The clinical manifestations and pathomechanics of contracture of the extensor mechanism of the knee. (1/666)

Experience with thirty-eight Asian children and adolescents who presented with either stiffness of the knee, genu recurvatum, habitual dislocation of the patella or congenital lateral dislocation of the patella showed that all those disorders were manifestations of contracture of the extensor mechanism, which fell into two groups according to the components involved. In Group I the main components affected were in the midline of the limb, namely rectus femoris and vastus intermedius; these patients presented with varying degrees of stiffness of the knee, or worse, with genu recurvatum. In Group II the main components involved were lateral to the midline of the limb, namely vastus lateralis and the ilio-tibial band; these patients presented with habitual dislocation of the patella, or worse, congenital lateral dislocation of the patella. In both groups untreated patients developed secondary adaptive changes such as subluxation of the tibia or marked genu valgum which made operative procedures more formidable and less effective. Release of the contracture should therefore be performed as early as possible.  (+info)

An operation for chronic prepatellar bursitis. (2/666)

An operation for chronic prepatellar bursitis is described in which only the posterior wall of the bursa is excised, thus preserving, undamaged, healthy and normally sensitive skin. This procedure is easier and less traumatic than complete excision of the bursa and results in fewer complications. It is suggested that removal of tha anterior wall of the bursa results in unnecessary and harmful interference with the underlying skin. The operation described gives a good functional and structural result; leaving the anterior wall of the bursa does not predispose to recurrence.  (+info)

The locked patella. An unusual complication of haemophilia. (3/666)

Mechanical derangements of the knee are an uncommon complication of chronic haemophiliac arthropathy. Two patients with locking of the patella were treated by manipulation. The mechanism of the injury was forced flexion of the knee joint beyond the limit of its restricted range. The injury is a serious one and may take six months to recover.  (+info)

Histomorphometry of the aging human patella: histologic criteria and controls. (4/666)

OBJECTIVE: A histomorphometric analysis of patellae from necropsies on persons between the third and tenth decades of life was carried out to trace the natural history of osteoarthritis. DESIGN: Minutiae of the histological changes in the surface and basilar portions of the articular cartilage were developed as criteria for the quantitation. A total of 99 patellas were harvested in the stated age range. The present study reports the results of ten grossly and radiologically normal specimens from subjects 23-32 years old served as controls. RESULTS: None of the control patellae were entirely histologically normal. Abnormality of the cartilage surface did not consistently proceed remodeling at the attachment to the subchondral plate. CONCLUSIONS: This observation throws into question the concept that osteoarthritis has a single histogenesis or always arises in articular cartilage.  (+info)

Knee pain and the infrapatellar branch of the saphenous nerve. (5/666)

Pain over the front of the knee is common after surgery or trauma but often a definite diagnosis is difficult to make. Over the past year we have seen five cases in which the pain could be ascribed to damage to a branch of the infrapatellar branch of the saphenous nerve. Two were subsequent to trauma and three to surgical procedures. In all five cases surgical exploration gave symptomatic relief. Eight cadaveric knees were prosected to explore further the anatomy of this nerve in relation to the injuries. Injury to one of these branches should be considered in cases of persistent anterior, anteromedial or anterolateral knee pain or neurological symptoms following surgery or trauma.  (+info)

Bone scintigraphy in chronic knee pain: comparison with magnetic resonance imaging. (6/666)

OBJECTIVE: To compare increased bone uptake of 99Tcm-MDP and magnetic resonance (MR) detected subchondral lesions, osteophytes, and cartilage defects in the knee in middle aged people with long-standing knee pain. METHODS: Fifty eight people (aged 41-58 years, mean 50) with chronic knee pain, with or without radiographic knee osteoarthritis, were examined with bone scintigraphy. The pattern and the grade of increased bone uptake was assessed. On the same day, a MR examination on a 1.0 T imager was performed. The presence and the grade of subchondral lesions, osteophytes, and cartilage defects were registered. RESULTS: The kappa values describing the correlation between increased bone uptake and MR detected subchondral lesions varied between 0.79 and 0.49, and between increased bone uptake and MR detected osteophytes or cartilage defects the values were < 0.54. The kappa values describing the correlation between the grade of bone uptake and the grade of the different MR findings was < 0.57. CONCLUSIONS: Good agreement was found between increased bone uptake and MR detected subchondral lesion. The agreement between increased bone uptake and osteophytes or cartilage defects was in general poor as well as the agreement between the grade of bone uptake and the grade of the MR findings.  (+info)

Knee cartilage topography, thickness, and contact areas from MRI: in-vitro calibration and in-vivo measurements. (7/666)

OBJECTIVE: This study assessed the three-dimensional accuracy of magnetic resonance imaging (MRI) for measuring articular surface topographies and cartilage thicknesses of human cadaveric knee joints, by comparison with the calibrated stereophotogrammetric (SPG) method. METHODS: Six fresh frozen cadaveric knees and the knees of four volunteers were imaged with a three-dimensional spoiled gradient-recalled acquisition with fat suppression using a linear extremity coil in a 1.5 T superconducting magnet. The imaging voxel size was 0.47 x 0.47 x 1.0 mm. Both a manual and a semi-automated segmentation method were employed to extract topographic measurements from MRI. Following MRI, each of the six cadaveric knees was dissected and its articular surfaces quantified using stereophotogrammetry. The MRI surface measurements were compared numerically with the SPG measurements. RESULTS: For six cadaveric knees, the average accuracies of cartilage and subchondral bone surface measurements were found to be 0.22 mm and 0.14 mm respectively and the thickness measurements demonstrated an average accuracy of 0.31 mm. It was found that while most of the error may be attributed to random measurement error, the accuracy was somewhat affected by systematic errors. For each bone of the knee, accuracies were most favorable in the patella, followed by the femur and then the tibia. The more efficient semi-automated method provided equally good and sometimes better accuracies than manual segmentation. CONCLUSIONS: This study demonstrates that clinical MRI can provide accurate measurements of cartilage topography, thickness, contact areas and surface curvatures of the knee.  (+info)

Localization of a gene for familial patella aplasia-hypoplasia (PTLAH) to chromosome 17q21-22. (8/666)

Patella aplasia-hypoplasia (PTLAH) is a rare genetic defect characterized by congenital absence or marked reduction of the patella. PTLAH can occur either as an isolated defect or in association with other malformations, and it characteristically occurs in the nail-patella syndrome and in some chromosome imbalances. We report the first evidence of linkage for isolated PTLAH in an extended Venezuelan family. After exclusion of the candidate chromosome regions where disorders associated with PTLAH have been mapped, a genomewide scan was performed that supported mapping of the disease locus within a region of 12 cM on chromosome 17q22. Two marker loci (D17S787 and D17S1604) typed from this region gave maximum LOD scores >3. Accordingly, multipoint analysis gave a maximum LOD score of 3.39, with a most likely location for the disease gene between D17S787 and D17S1604. Sequencing of the noggin gene, a candidate mapping between these markers, failed to reveal any mutation in affected subjects.  (+info)

Whilst patellofemoral pain is one of the most common musculoskeletal disorders presenting to orthopaedic clinics, sports clinics, and general practices, factors contributing to its development in the absence of a defined arthropathy, such as osteoarthritis (OA), are unclear. The aim of this cross-sectional study was to describe the relationships between parameters of patellofemoral geometry (patella inclination, sulcus angle and patella height) and knee pain and patella cartilage volume. 240 community-based adults aged 25-60 years were recruited to take part in a study of obesity and musculoskeletal health. Magnetic resonance imaging (MRI) of the dominant knee was used to determine the lateral condyle-patella angle, sulcus angle, and Insall-Salvati ratio, as well as patella cartilage and bone volumes. Pain was assessed by the Western Ontario and McMaster University Osteoarthritis Index (WOMAC) VA pain subscale. Increased lateral condyle-patella angle (increased medial patella inclination) was associated
Patellar subluxation syndrome, also known as patellar instability, or unstable kneecap is an injury that is concerned with the kneecap. Patellar subluxation is more common than patellar dislocation and is just as disabling. In this condition, the patella repetitively subluxates and places strain on the medial restraints and excessive stress/tension on the patellofemoral joint. Patellar subluxation can be caused by osseous abnormalities, such as incorrect articulation of the femoral groove with the patella, trochlear dysplasia, or patella alta, which is a distance of greater than 20 mm between the tibial tubercle and the trochlear groove. It can also result from soft-tissue abnormalities, such as a torn medial patellofemoral ligament, or a weakened vastus medialis obliquus. Symptoms are regulated by the amount of activity. Such pain is commonly caused by running and jumping sports and activities that place large forces on the patellofemoral joint. Symptoms usually include: Knee buckles and can no ...
These were the words of my first knee specialist doctor.. I was diagnosed with patella baja and infrapatellar contracture syndrome in July of 2001. This came 11 mos after my horseback riding accident, where I broke my tibia and fibula in 4 places. I developed arthrofibrosis of my knee, after the nailing procedure thru my knee, to repair the tibia fractures.. I was referred to a knee specialist in my town, by the OS who performed a tibia/fibula derotational osteotomy, to correct a malunion of the tibia. I had continuing problems with my knee from the surgery in the form of flexion and extension deficits, swelling, pain, heat, very tight patella and subluxation. I had a series of xrays taken by this knee specialists office. When the doctor came in, he immediately informed me, I had patella baja. He proceeded to show me, on the xrays, how low my patella was sitting. He took various measurements on the xrays to confirm this. He performed a thorough physical exam. This showed a patella with very ...
The patello-femoral joint refers to a specific part of the knee joint. Medically, the kneecap is known as the patella and the thigh bone is called the femur. The knee joint is composed of three bones - the femur (or thigh bone), the tibia (or shin bone), and the patella (or kneecap). The parts of the knee joint are subdivided into the tibio-femoral joint which refers to the joint space between the tibia and the femur; and the patello-femoral joint which is the joint space between the patella and the femur. Both of these joints (patello-femoral and tibio-femoral) form the knee joint.. The patella is connected to the quadriceps tendon at the top of the patella. The quadriceps tendon attaches to the quadriceps muscle which attaches to the pelvis. The patellar tendon goes from the bottom of the patella to the front of the tibia known as the tibial tubercle. When the quadriceps muscle contracts (shortens), it pulls the patella which in turns pulls on the tibial tubercle, which causes the knee to ...

Seattle Veterinary Specialists Clinical Update MEDIAL PATELLAR LUXATION (MPL) Patella luxation occurs due to a combination of anatomic abnormalities in the rear limb that force the knee cap out of its normal groove ANATOMY The patella (knee cap) is part of the quadriceps muscle (large muscle group on the front of the thigh) mechanism. The muscle originates at the top of the femur and inserts, via the patella ligament, onto the tibial tuberosity. The quadriceps mechanism forms a straight line from origin to insertion. The patella rides in a groove in the distal femur called the trochlea. WHY DOES THE PATELLA DISLOCATE? If the femur is slightly bowed and the tibial tuberosity (insertion point of the patella ligament) is medially displaced, then the patella is pulled toward the medial side (inside) of the knee. The tissues on the lateral side (outside) of the knee tend to stretch and the patella eventually dislocates medially. The trochlea is often more shallow than normal. [1] CLINICAL SIGNS Dogs ...
Acute traumatic, unilateral, quadriceps rupture after patellectomy is rare. We present a 42-year old male who experienced a unilateral left quadriceps tendon rupture following assault by four people. Twenty-seven years before this injury, the patient had suffered ipsilateral femur and comminuted patellar fractures, which were managed by intramedullary nailing and patellectomy respectively. We performed primary end to end repair of the torn tendon. Postoperatively, histology revealed findings consistent with pre-existent degenerative changes. The patient made good recovery, and returned to his former occupation which was reliant on his ability to drive. Degenerative changes of the tendon of the extensor mechanism of knee following patellectomy may predispose the quadriceps tendon to traumatic rupture. Early operative intervention and protracted rehabilitation are required to obtain the best functional results.
Medially luxating patella is a condition where the patella (knee cap) pops in and out of place in response to extension, flexion, or weight bearing of the knee joint. The disease is congenital in origin, resulting from inherited shallow patellar grooves (the groove in which the patella normally sits in), an inherited abnormally medially located tibial attachment point for the patellar tendon or both. The luxations almost always occur in the medial direction (toward the center of the body). For example, in the left limb, the tendency is for the patella to luxate to the right. The opposite is true for the right limb. The majority of luxating patella cases are bilateral.. Luxations cause inflammation and pain in the knee joint. Also, because the chief purpose of the patella is to redistribute tendon forces to best handle weight bearing and stress, patellar luxations tend to throw off the physics of the entire leg, causing excessive wear on the hips and ankles. This predisposes to degenerative joint ...
There has been an interesting series of commentaries based on the initial paper by Pan et al. 1-4 I note with interest the suggestion by Binks et al 4 that to preserve the infrapatellar fat pad (IPFP) and perform later arthroscopic resection on a case by case basis may be a viable option for management of anterior knee pain (AKP) after total knee arthroplasty (TKA). This is contrary to the solution offered by Han et al 3 to use a prospective MRI to screen patients prior to TKA with subsequent resection based on signal changes within the IPFP. This approach would however, prove difficult in the resource-constrained environment of most primary care facilities.. Current arguments in support of preserving the IPFP are largely based around the incidence of postoperative AKP.5 6 One area of conflicting evidence is the incidence of patella tendon shortening, also known as patella baja, after resection. Recent studies have shown no significant effect on postresection patella tendon length.7 8 This ...
You, your family veterinarian, and Dr Jha (Board Certified Surgeon) will use several diagnostic tools to confirm a patella luxation in your pet friend. You may notice lameness mainly with a skipping gait in your dog and your dog lifting the affected leg intermittently. Your primary care veterinarian will detect pain and a dislocated patella on physical exam. We complete the diagnostic process by performing a thorough orthopedic and neurological examination, follow up x-rays under sedation or general anesthesia. In many dogs we recommend a CT scan to diagnose the complex causes of patella luxation and plan for surgical correction. An experienced surgeon can palpate the knee joint with patella luxation and generally be able to tell the grade of luxation and recommend the level of treatment needed. Patella luxation is divided into grades I,II, III, and IV. Grade III and IV generally need a surgical correction and in some instances a patella luxation of grade II can also benefit from surgical ...
A patella drill guide includes a base portion rotatably mounted on a bone-gripping component. A trial portion with a contoured articulation surface is above the base portion. The base portion and trial portion have aligned drill guide bores. The base portion and trial portion can be rotated together on the bone-gripping component to optimize the positions of the drill guide bores with respect to the patella surface, thereby optimizing the locations of the mounting pegs of the patella implant component on the patella to optimize the orientation of the patella implant component. The base and the bone-gripping component may be unitary so that the entire assembly rotates on the patella about the central longitudinal axis of the bone-gripping component.

Introduction. Sleeve fractures are rare in the skeletally immature child and represent chondral or osteochondral injuries that occur between the cartilage sleeve and the main part of the patella and ossific nucleus. Fractures of the patella collectively form 1% of all fractures, with sleeve fractures representing 57% of these (1-3). This is due to the anatomy of the immature patella, which begins to ossify at about 3-6 years of age and is surrounded by a layer of protective cartilage and soft tissue. It is this eggshell-like fragment that is avulsed that consists of cartilage, periosteum and retinaculum (1). The greatest challenge is the early diagnosis of these fractures, which are often missed or delayed because much of the fragment is unossified and can be missed on plain radiographs, these fractures are rare(4), and primary clinicians lack knowledge of them (5). At times the only indication of this fracture is a patella alta that is determined using the Insall-Salvati index. Neglect or ...

What is it and how does it occur? Patella luxation is otherwise known as knee dislocation and is a common condition typically affecting young small and toy-breed dogs. The patella in each knee lies in a trochlear groove and when it luxates it moves out of this groove causing pain and instability. Usually luxations are related to congenital changes, that is, the animal is born with a shallow groove or the quadriceps tendon attaches to the tibia bone unusually so that the patella slips out when the quadriceps are flexed. Trauma can also cause luxation and obese dogs are more prone to luxation.. Initially pain may only be apparent when the patella is not sitting in the groove however over time the groove becomes worn and flattened so the patella slips in and out easily and arthritis develops within the joint.. What are the signs? Most dogs will show intermittent lameness. Often the lameness is described as suddenly lifting the back leg up at an odd angle for a few steps, perhaps flicking the leg a ...

Grades II, III, and IV require surgery to correct, if the animal has difficulty walking. The surgery required is governed by the type of abnormality present, but often involves a sulcoplasty, a deepening of the trochlear sulcus where the patella sits, a realignment of the attachment of the patella tendon on the tibia, and tightening or releasing of the capsule on either side of the patella, according to which side the patella is slipping. Some grade IV conditions may require more involved surgery to realign the femur and/or tibia. A therapeutic dosage of glucosamine can be used as a preliminary treatment to strengthen ligaments and the surrounding tissues of the joint and can delay or prevent surgery.[5] Additional help can be given with the use of pet ramps, stairs, or steps. These can help the animal travel from one place to another, especially up and down, without adding any pain or damage to the patella. ...
The substance of the patella The substance of the patella in older persons is quite hard and solid, notwithstanding Galens assertion that it is cartilaginous on the outside; 11 Marinus likewise, among other prominent anatomists, independently called it a cartilaginous bone and devoted a chapter to it in a book which he wrote, On Cartilaginous Bones. 12 These authors were perhaps thinking of the material of the tendons to which the patella is attached, which when boiled resembles soft cartilage, like the parts from which the sinewy heads of the muscles or the ligaments take their origin or into which they are inserted. But when the patella is properly cleaned of tendons 13 it is seen to be in no way cartilaginous, but quite solid and strong not only in humans but also in cattle, sheep, and other quadrupeds. Before their knee joint, as well, the Maker of things placed a patella, much longer and narrower than in humans, as in most birds it is wider and shorter. 14 ...
Does the problem improve with rest? With an acute patella luxation the lameness is usually the result of trauma and so this questioning is not so important as the physical examination. With a chronic patella luxation, the lameness usually varies, is often worse when first getting up after lying down, may produce some skipping during exercise or low grade partial weight bearing lameness that is slowly becoming more noticeable and does not change much despite rest.. Your veterinarian will ask you to walk and then trot your dog, in order to observe the lameness. With your pet in a standing position, the affected side will be compared to the opposite side for muscle wasting, patella position while standing, swelling of the knee joint, thickening of the joint, position and thickness of the patella tendon and its attachment to the tibia, the bone below the joint.. The stifle joint will be put through a normal range of motion, paying particular attention to the tracking of the patella through its ...

While epidemiological studies have reported a potential role for hypercholesterolemia (HCE) in osteoarthritis (OA), the association between HCE and OA has yet to be clarified. Adipose tissue is a primary locus for cholesterol metabolism and the presence of HCE reportedly causes adipose dysfunction. The knee joint contains adipose tissue in the form of the infrapatellar fat pad (IPFP), which has been shown to contribute to the pathophysiology of OA in the knee via the secretion of inflammatory mediators. However, the effect of HCE on the expression of inflammatory mediators in the IPFP has not been elucidated. IPFP and synovial tissues (ST) were extracted from 145 subjects with OA, diagnosed by radiography, during total knee arthroplasty. OA patients were divided into three groups according to their total cholesterol levels (Desirable, Borderline high and High) based on the National Cholesterol Education Program Adult Treatment Panel III (NCEPATP III). We examined the expression of cyclooxygenase-2 (COX

0058]In the illustrative embodiment of FIGS. 1-4, offsetting the curved peak surface 18 of the patella component 10 in the superior direction in such a manner results in a thickened superior edge relative to conventional dome-shaped patella components in which the tip of the curved peak surface (i.e., the posterior-most point) is positioned in the center of the component. Specifically, as can be seen in FIGS. 3 and 4, the superior edge of the patella component 10 is thicker than its inferior, medial, and lateral edges. Because the edges of the patella component 10 are rounded, such a feature can be demonstrated geometrically in a number of different manners. One way to do so is shown in FIGS. 3 and 4 and described hereinafter. However, it should be appreciated that the relative thickness of each of the components edges may be demonstrated geometrically in other ways. In the illustrative manner described herein, the tangent point of the edges rounded corner serves as a common point of reference ...

Aquatic physiotherapy can be an excellent tool in the management of patellofemoral pain. Here is a recent case study where dry land treatment was incorporated with aquatic therapy.. Our case patient (PB) had a previous history of right sided patellofemoral pain and six years prior had undergone lateral release surgery to try and correct lateral tilt and maltracking of his patella. He is a keen amateur cyclist, a sport which he maintains to a good level and he had recently completed LEtape Du Tour a gruelling amateur cycling event replicating one of the Tour De France stages. Not long after completing this event he described an innocuous flick with his foot to move a ball situated on the floor and the onset of his anterior knee pain.. On assessment his patella was excessively mobile laterally with poor vastus medialis obliquus muscle bulk and function, which is a muscle on the inside of the knee that helps to provide support to the patella from laterally tracking. He had weak lateral hip and ...
At the recent Patellofemoral Research Retreat that I attended there was a lot of focus on patellofemoral pain as a continuum with patellofemoral osteoarthritis. In line with this question there was interest around dysplasia. I personally am very interested by patellofemoral dysplasia and think that it is seen on a huge spectrum with many patients showing subtle anatomical variation. Dysplasia is such a good example of where understanding the anatomy really helps to alter treatment. So, for example if a patient has a lateralized tibial tuberosity I understand they will find it hard to absorb medial femoral rotation, so I think of particularly addressing horizontal plane control. In contrast someone with a long patella tendon, (patella alta) will take longer into flexion for their patella to engage, and hence receive stability from the trochlea. Understanding this anatomy leads me to focus their dynamic control work in the early ranges of knee flexion ...

Chondroblastoma is a rare tumor, representing only 1-3% of all primary bone tumors, with local pain and swelling lasting for several months as the most important symptoms. It is usually seen as a lytic lesion involving the epiphysis with a thin border of sclerosis and central punctuate calcification in half of the cases in radiographs. It usually causes expansion or enlargement in the affected site. Primary patella lesions are categorized into benign and malignant tumors and metabolic disorders. Giant cell tumor is the most likely differential diagnoses with tumors of the patella. Patella is a relative uncommon site for chondroblastoma.Most of cases of chondroblastoma in patella reported in literature are treated with patellectomy.We treated a large chondroblastic lesion in patella of an 22 year old male with curettage, burring and bone graft and the result was satisfactory after 8 months postoperation,with complete consolidation of new bone on radiographs, absence of pain and full range of knee ...
The patella tendon connects the patella to the tibia (shin bone) and is very important because it works in unison with the quadriceps tendon to straighten the leg and stabilize the knee. Forceful jumps and falls and sometimes lacerations cause patella tendon tears. Tears may be partial or complete. Partial tears are usually treated non-surgically and complete tears usually require a patella tendon repair. Torn patella tendon symptoms patients should be aware of include the following:. ...
Recurrent patella dislocation can be caused by bony abnormalities, such as patella alta, increased tibial tubercle lateralization, trochlea dysplasia, excessive femoral neck anteversion and external tibial torsion. It can also be caused by soft tissue abnormalities such as a ruptured medial patellofemoral ligament (MPFL) or a weak vastus medialis obliquus. It has been reported in…
Aims: The aim of the study was to assess quadriceps myoelectric activation and manifestation of fatigue in a group of healthy active elderly males compared to a control group of healthy active young males. Methods: fourteen elderly (65-77 years) and 12 young males (21-26 years) performed three knee position tasks aimed to maintain 60deg angle (0deg= full extension) at 30%, 50% and 70% of knee extension maximal voluntary contraction (MVC). Initial values and rate of change of average rectified value (ARV), mean spectral frequency (MNF), and muscle conduction velocity (CV) were estimated recording surface EMG signals (sEMG) from vastus lateralis (VL) and vastus medialis obliquus (VMO) muscles of dominant limb, using eight electrodes arrays. Friedman tests were used to compare sEMG variables among the three contraction levels, whereas Mann Whitney U tests were used to compare the groups. Results: In VMO: Friedman and post hoc tests found significant increase of CV at 50% and 70% with respect to ...

TY - JOUR. T1 - Fracture of the patella following total knee arthroplasty. AU - Le, Anh X.. AU - Otsuka, Norman Y.. AU - Bhargava, Manoj. AU - Cameron, Hugh U.. AU - Harrington, Ian J.. PY - 1999/4/1. Y1 - 1999/4/1. N2 - The charts of 21 patients (22 knees) with significant radiographic changes of the patella after total knee arthroplasty were reviewed. The average patient age was 73 years, and average follow-up after arthroplasty was 7.3 years. Lateral release, fat pad excision, quadriceps tendon release, and previous surgery were implicated in the etiology of fracture of the patella. Five cases had type 1 pattern (sclerosis, fragmentation, and no fracture), 5 cases had type 2 pattern (undisplaced fracture and fragmentation), and 12 cases had type 3 pattern (displaced fracture and fragmentation). Type 1 and 2 patterns required no surgical treatment and were rated good to excellent according to the Hospital for Special Surgery Disability Score Sheet. Patients with a type 3 pattern who did not ...

GARCIA, Fabiana R. et al. Effects of electrical stimulation of vastus medialis obliquus muscle in patients with patellofemoral pain syndrome: an electromyographic analysis. Rev. bras. fisioter. [online]. 2010, vol.14, n.6, pp.477-482. ISSN 1413-3555. http://dx.doi.org/10.1590/S1413-35552010000600005.. BACKGROUND: The use of surface electromyography (SEMG) has been considered a tool for quantitative assessment of patellofemoral pain syndrome (PFPS). Conservative treatments aim to improve patellar alignment, and electrical stimulation of the vastus medialis obliquus (VMO) muscle has been considered effective because it is selective and does not cause joint irritation. OBJECTIVE: This study aims to investigate the efficiency of a muscle strengthening program with electrical stimulation of the VMO muscle in PFPS by SEMG. METHODS: A group of ten young women (age: 23.1±4.9 years; body mass: 66.8±14.0 kg; height: 1.63±6.9 cm; BMI: 25.1±5.6 kg/m2) with unilateral PFPS participated in the study. They ...

Displaced transverse fractures of the body of the patella are usually associated with disruption of extensor mechanism and should be fixed surgically. The most common method is a tension band wiring (TBW) technique. Some surgeons concurrently employ an augmented circumferential cerclage wiring (ACCW) technique to help fracture stabilization and aid in fracture healing; however, its role and effect on the treatment outcomes is unclear. We performed a STROBE-compliant retrospective observational cohort study on all cases of acute closed patella fracture that were treated at our institution between 2006 and 2012. Of 185 episodes, 72 (38.9%) were eligible for this study according to our inclusion/exclusion criteria. We classified these subjects with AO/OTA type 34-C1.1 or 34-C2 lesions into two groups for analyses: fractures treated with modified TBW and ACCW (group 1, n = 27) and those treated with modified TBW alone (group 2, n = 45). Plain radiographs were used to evaluate radiographic outcomes and the
Introduction. A2 Biology Investigation Comparing the mean ratios of shell height/diameter of the Patella spp on an exposed and sheltered shore Rebekah Riley Candidate number: 5037 Centre number: 28384 Background Information Limpets are slow moving molluscs, characteristic of rocky shores and are very well adapted to life on the seashore. They have a hard shell to protect themselves against predators and damage from moving rocks, and a large muscular foot that enables them to clamp firmly onto rocks to conserve water and maintain their position during rough weather. The most common limpet is Patella vulgata. The conical shell of Patella vulgata can be up to 6 cm long with radiating ridges and the apex central or slightly anterior. Orton (1928) has shown that individuals that inhabit the upper shore generally have a taller shell and smaller shell length when compared to juveniles and lower shore organisms. The thickness of shells is believed to be concerned with heat insulation and water ...

Dislocation or subluxation of the patella or kneecap is a common acute injury for young athletes, especially in sports and activities such as basketball, football, lacrosse, gymnastics and dance. These injuries may be routinely observed in clinic, and depending on severity, may warrant a referral to a pediatric orthopedic specialist.. The term patellofemoral instability can refer to both the condition in which an individual experiences a traumatic dislocation of their patella, and the general instability that a patient can feel or a physician may observe upon examination. In both cases, there are observations that may be made or treatments that can be provided that may reduce the risk of a dislocation event occurring in the future, as well as protect a young athlete from further damage.. Notes talked to Matthew Milewski, MD, a pediatric orthopedic surgeon in Boston Childrens Orthopedics and Sports Medicine Center, about how to best care for young athletes with patellofemoral ...
OBJECTIVE:To examine the effect of the application of tape over the patella on the onset of electromyographic (EMG) activity of vastus medialis obliquus (VMO) relative to vastus lateralis (VL) in participants with and without patellofemoral pain syndrome (PFPS). DESIGN:Randomised within subject. SETTINGS:University laboratory. PARTICIPANTS:Ten participants with PFPS and 12 asymptomatic controls. INTERVENTIONS:Three experimental taping conditions: no tape, therapeutic tape, and placebo tape. MAIN OUTCOME MEASURES:Electromyographic onset of VMO and VL assessed during the concentric and eccentric phases of a stair stepping task. RESULTS:When participants with PFPS completed the stair stepping task, the application of therapeutic patellar tape was found to alter the temporal characteristics of VMO and VL activation, whereas placebo tape had no effect. In contrast, there was no change in the EMG onset of VMO and VL with the application of placebo or therapeutic tape to the knee in the asymptomatic ...

Or maybe its Patellofemoral Pain Syndrome (PFPS) aka Runners Knee where the patella gets subtley out of its groove creating inflamation. Its caused by a muscle imbalance which results in the patella getting pulled to one side. I suffered from that and PT had me do wall sits amongst other things and did stim to strenghten my Vastus Medialis (huge on cyclists). BUT THE KEY was that they first taped my knee using a McConnell taping technique. It was the first time I had excercised pain free in years. I learned how to do it myself and was running pain free. That and the PT got me going again. Id first take some time off and ice to get the inflamation down. Check these out and see if the symptoms match. Maybe just try the taping and see if the pain is reduced too ...

To evaluate the postoperative change in patellar position after medial closed distal femoral osteotomy (DFO) performed for valgus osteoarthritic knees. The study included 21 consecutive knees in 20 patients undergoing DFO. A minimum of 2-year follow-up data was obtained for all subjects with a mean follow-up period of 42 months (range 31-59 months). The patellar position was evaluated on plain radiographs preoperatively, 1-year postoperatively, and 2-year postoperatively. For patellar height, the modified Insall-Salvati Index (mISI), modified Caton-Deschamps Index (mCDI) and modified Blackburne-Peel Index (mBPI) were measured on the standing lateral radiographs. Patellofemoral alignment on the axial plane was assessed on skyline views with 30° flexion based on the measurements for lateral patellar tilt (LPT) and lateral patellar shift (LPS). Measured values at pre- and postoperative phases were statistically compared using a two-way analysis of variance. All indices including mISI, mCDI, mBPI, LPT and
Patella Tendinopathy (also commonly referred to as Jumpers Knee) is a failed healing process of the patella tendon that results in pain and stiffness at the front of the knee just below the knee cap.
In adolescents and in athletic children who are growing rapidly, pain may be localised to the anterior part of the knee where the patella, the patellar tendon, femoral condyles, and quadriceps muscle form an important unit. Pain in this area can be due to a number of causes, including a patellar tracking abnormality, chondromalacia patellae (abnormality of the cartilage underlying the patella), recurrent subluxation of the patella, and osteochondritis dissecans. These latter two disorders should be diagnosed from the history and radiographs. Physiotherapy and medial patellar strapping may help in anterior knee pain.17 Back pain, which is common in adolescence (8% of 14-15 year olds),18 particularly if the pain is localised in the paravertebral muscles, may respond to physiotherapy once other organic treatable causes have been excluded. Again, it is important to be aware that unrecognised organic causes may evolve with the passage of time and reassessment may be necessary.. After an injury which ...
Jumping puts a great deal of force on the joints and tendons. Athletes who play basketball, volleyball, and/or jumping track sports sometimes complain of pain and swelling in the knee area. Jumpers knee is most commonly associated with an inflamed patella tendon but sometimes the pain originates in the quadriceps tendon. A thorough evaluation can help determine source of pain and the best plan for recovery.. Jumpers knee is most often associated with a sharp pain in the front of the knee when athletes take off and land following a jump. It is critical for the healthcare specialist to determine if the pain originates from the quadriceps femoris or patella tendon.. These two tendons differ in many ways and the approach to rehabilitation of an injured tendon should be based on its characteristics. The quadriceps tendon originates at the musculotendinous junction of the four quadriceps femoris muscles and crosses the knee joint by engulfing the patella and extending to the tibia via the ...

Radiofrequency ablation and percutaneous cryoneurolysis to relieve knee pain requires treating large areas to ensure coverage due to high variability in the sensory innervation of the knee and limitations of current methods for defining treatment targets. This study sought to define and validate a new treatment approach targeting the major sensory nerves of the superior patella and expand upon previous work to define a more efficient treatment approach targeting the sensory nerves of the inferior patella. Transcutaneous electrical nerve stimulation and ultrasound were used to evaluate the location and relationship of the cutaneous nerves to the superior and inferior aspects of the knee in 25 healthy volunteers. Using information derived from these evaluations, investigators defined new linear target treatment areas, or treatment lines, using anatomical landmarks, which were validated against locations of sensory nerves through cadaveric dissection of 15 fresh specimens. The proposed treatment lines
This condition occurs when the tendon that holds the patella, (the knee cap), to the tibia tears and splits apart, allowing the patella to slide upward. This causes pain and an inability to straighten the knee.
BACKGROUND:Reconstruction of the extensor mechanism after resection of the proximal tibia is challenging, and several methods are available. A medial gastrocnemius flap commonly is used, although it may be associated with an extensor lag. This problem also is encountered, although perhaps to a lesser extent, with other techniques for reconstruction of the extensor apparatus. It is not known how such lag develops with time and how it correlates with functional outcome.QUESTIONS/PURPOSES:We therefore (1) assessed patellar height with time, (2) correlated patellar height with function using the Musculoskeletal Tumor Society (MSTS) score, and (3) correlated patellar height with range of motion (ROM) after medial gastrocnemius flap reconstruction.METHODS:Sixteen patients underwent tumor endoprosthesis implantation and extensor apparatus reconstruction between 1997 and 2009 using a medial gastrocnemius flap after sarcoma resection of the proximal tibia. These patients represented 100% of the ...

The lateral surface, quadrilateral in form, is broad, rough, convex, and marked by a diagonal impression, which extends from the postero-superior to the antero-inferior angle, and serves for the insertion of the tendon of the gluteus medius. Above the impression is a triangular surface, sometimes rough for part of the tendon of the same muscle, sometimes smooth for the interposition of a bursa between the tendon and the bone. Below and behind the diagonal impression is a smooth triangular surface, over which the tendon of the gluteus maximus lies, a bursa being interposed. The medial surface, of much less extent than the lateral, presents at its base a deep depression, the trochanteric fossa (digital fossa), for the insertion of the tendon of the obturator externus, and above and in front of this an impression for the insertion of the obturator internus and superior and inferior gemellus muscles. ...

The antero-lateral border begins above in front of the head, runs vertically downward to a little below the middle of the bone, and then curving somewhat lateralward, bifurcates so as to embrace a triangular subcutaneous surface immediately above the lateral malleolus. This border gives attachment to an intermuscular septum, which separates the extensor muscles on the anterior surface of the leg from the peronaei longus and brevis on the lateral surface. The antero-medial border, or interosseous crest, is situated close to the medial side of the preceding, and runs nearly parallel with it in the upper third of its extent, but diverges from it in the lower two-thirds. It begins above just beneath the head of the bone (sometimes it is quite indistinct for about 2.5 cm. below the head), and ends at the apex of a rough triangular surface immediately above the articular facet of the lateral malleolus. It serves for the attachment of the interosseous membrane, which separates the extensor muscles in ...

Hand and wrist injuries are reported to account for fifteen to twenty percent of emergency room injuries, and metacarpal fractures represent a significant number of those injuries. Hand injuries of this sort are most prevalent among fifteen- to thirty-five-year-old males, and the fifth metacarpal is the one most commonly affected.[10] Males are nearly fifty percent more likely to sustain fracture from a punch mechanism than females. Male intentional punch injuries are correlated predominantly with social deprivation, while female punch intentional injuries show more correlation with psychiatric disorders.[11] Approximately 3.7 male hand injuries, per 1000, per year, and 1.3 female hand injuries, per 1000, per year, have been reported. Common mechanisms of injury are gender specific. Although the fiscal cost is not available, it can be asserted that the cost is reasonably significant per individual, depending on the cost of emergency care, immobilization, surgery, follow up doctors' visits, etc. ...
... is most common in younger people, accounting for 17% of injuries to the body in those aged 0-6 years compared to an average of 5% across all ages.[40] It is more frequently observed in males compared to females.[41] Traumatic dental injuries are more common in permanent teeth compared to deciduous teeth and usually involve the front teeth of the upper jaw.[42] "The oral region comprises 1% of the total body area, yet it accounts for 5% of all bodily injuries. In preschool children, oral injuries make up as much as 17% of all bodily injuries. The incidence of traumatic dental injuries is 1%-3%, and the prevalence is steady at 20%-30%."[43] Almost 30% of the children in pre-school have mostly experienced trauma to primary teeth. Dental injuries involving the permanent teeth happen to almost 25% of children in school and 30% of adults. The incident varies in different countries as well as within the country itself. Dental traumatic accidents depends on one's activity status and also ...

Treatment of scaphoid fractures is guided by the location in the bone of the fracture (proximal, waist, distal), displacement (or instability) of the fracture, and patient tolerance for cast immobilization.. Non displaced or minimally displaced waist and distal fractures have a high rate of union with closed cast management. The choice of short arm, short arm thumb spica or long arm cast is debated in the medical literature and no clear consensus or proof of the benefit of one type of casting or another has been shown; although it is generally accepted to use a short arm or short arm thumb spica for non displaced fractures.[5] Non displaced or minimally displaced fracture can also be treated with percutaneous or minimal incision surgery which if performed correctly has a high union rate, low morbidity and faster return to activity than closed cast management.[9]. Fractures that are more proximal take longer to heal. It is expected the distal third will heal in 6 to 8 weeks, the middle third will ...
Before the 18th century, distal radius fracture was believed to be due to dislocation of the carpal bones or the displacement of the distal radioulnar articulation. In the 18th century, Petit first suggested that these types of injuries might be due to fractures rather than dislocations. Another author, Pouteau, suggested the common mechanism of injury which leads to this type of fractures - injury to the wrist when a person falls on an outstretched hand with dorsal displacement of the wrist. However, he also suggested that volar displacement of the wrist was due to the ulnar fracture. His work was met with skepticism from colleagues and little recognition, since the article was published after he died. In 1814, Abraham Colles described the characteristics of distal end radius fracture. In 1841, Guilaume Dupuytren acknowledged the contributions by Petit and Pouteau, agreeing that the distal end radius fracture is indeed a fracture, not a dislocation. In 1847, Malgaigne described the mechanism of ...

Many important activities of daily life are dependent on the ability to grasp, pinch, and oppose the thumb. In fact, thumb function constitutes about 50% of overall hand function. These abilities are in turn dependent on an intact and functional thumb CMC joint. The CMC joint of the thumb allows a wide range of motion while maintaining stability for grasp and pinch. With this in mind, failure to properly recognize and treat the Bennett fracture will not only result in an unstable, painful, arthritic CMC joint with diminished range of motion: it will also result in a hand with greatly diminished overall function. In the case of the Bennett fracture, the proximal metacarpal fragment remains attached to the anterior oblique ligament, which in turn is attached to the tubercle of the trapezium bone of the CMC joint. This ligamentous attachment ensures that the proximal fragment remains in its correct anatomical position. The distal fragment of the first metacarpal bone possesses the majority of the ...

Contrast is defined as the difference in radiographic density between adjacent portions of the image. The range between black and white on the final radiograph. High contrast, or short-scale contrast, means there is little gray on the radiograph, and there are fewer gray shades between black and white. Low contrast, or long-scale contrast, means there is much gray on the radiograph, and there are many gray shades between black and white. Closely related to radiographic contrast is the concept of exposure latitude. Exposure latitude is the range of exposures over which the recording medium (image receptor) will respond with a diagnostically useful density; in other words, this is the "flexibility" or "leeway" that a radiographer has when setting his/her exposure factors. Images having a short-scale of contrast will have narrow exposure latitude. Images having long-scale contrast will have a wide exposure latitude; that is, the radiographer will be able to utilize a broader range of technical ...
