BACKGROUND: Articular cartilage repair in the knee is aimed at young patients with area(s) of cartilage loss and no deformity of the knee. These patients arent indicated for a knee replacement. Articular cartilage repair leads to improvement of symptoms of pain, locking and function. Traditionally, articular cartilage repair has always involved exposing the entire knee joint with an arthrotomy. This, though effective, would lead to a large scar, longer hospital stay, longer rehabilitation and its associated complications. Also, the use of Bone Marrow Aspirate Cells (BMAC) for the purpose of cartilage repair has long been debated with both sides having valid arguments and good surgical results.. RATIONALE: Both procedures in this study are performed in one stage, arthroscopically and as day case procedures, which offers minimal scarring and quicker recovery. This automatically confers a significant advantage over the traditional surgical techniques.. To correct the articular cartilage defect, ...

Idiopathic chondrolysis of the hip (ICH), a very rare disorder of unknown etiology, occurs mainly in female adolescents. Characterized by pain, limp, stiffness and radiological narrowing joint space from the rapid destruction of the articular cartilage, ICH sometimes results in ankyloses. We present the case of a 10-year-old girl diagnosed with ICH based on arthroscopic inspection and synovium biopsy. The femoral deformity appeared gradually, like a cam-type femoroacetabular impingement. She was treated with intensive rehabilitation and immunosuppressive drug. We later performed an arthroscopic bumpectomy for residual symptoms. She achieved a favorable outcome as a 15-year-old at the latest follow-up.. ...

Complex cartilage lesions of the knee including large cartilage defects, kissing lesions, and osteoarthritis (OA) represent a common problem in orthopaedic surgery and a challenging task for the orthopaedic surgeon. As there is only limited data, we performed a prospective clinical study to investigate the benefit of autologous chondrocyte implantation (ACI) for this demanding patient population. Fifty-one patients displaying at least one of the criteria were included in the present retrospective study: (1.) defect size larger than 10 cm2; (2.) multiple lesions; (3.) kissing lesions, cartilage lesions Outerbridge grade III-IV, and/or (4.) mild/moderate osteoarthritis (OA). For outcome measurements, the International Cartilage Societys International Knee Documentation Committees (IKDC) questionnaire, as well as the Cincinnati, Tegner, Lysholm and Noyes scores were used. Radiographic evaluation for OA was done using the Kellgren score. Patients age was 36 years (13-61), defects size 7.25 (3-17.5) cm2,

A gold standard treatment for articular cartilage injuries is yet to be found, and a cost-effective and predictable large animal model is needed to bridge the gap between in vitro studies and clinical studies. Ideally, the animal model should allow for testing of clinically relevant treatments and the biological response should be reproducible and comparable to humans. This allows for a reliable translation of results to clinical studies.This study aimed at verifying the Göttingen minipig as a pre-clinical model for articular cartilage repair by testing existing clinical cartilage repair techniques and evaluating the use of two defects per knee. Sixteen fully mature Göttingen minipigs were used. The minipigs received bilateral trochlear osteochondral drill-hole defects or chondral defects (Ø 6 mm), either one defect per knee or two defects per knee. The defects were treated with one of the following: Matrix-induced autologous chondrocyte implantation (MACI), microfracture (MFx), autologous-dual

Cartilage degradation would result in osteoarthritis (OA). p16INK4awas found in some age-related diseases. In this study, we aimed to determine the role of p16INK4a during OA and to investigate the underlying mechanisms. Enzyme-linked immunosorbent assay (ELISA) was performed to test the activity of senescence-associated secretory phenotype (SASP). Real-time PCR (RT-PCR) and Western blot were used to determine the expressions of target genes. The increased expressions of p16INK4a and E2F2 were accompanied with cartilage degradation induced by IL-1β. Over-expression of p16INK4a enhanced the secretion of SASP markers (TGFβ, IL-6, IL-8, IL-1α, MMP3 and MMP13), reduced the expression of type II procollagen (COL2A1).Thus, the over-expression of p16INK4a lead to cartilage injury. Moreover, we found that the expression of E2F2 was enhanced in p16INK4a over-expression group, and that cartilage injury caused by p16INK4a was alleviated by depleting E2F2. p16INK4a was up-regulated during the cartilage injury in

Postarthroscopic glenohumeral chondrolysis is a condition in which the cartilage located within the shoulder joint begins to deteriorate. This typically occurs after an individual has had surgery on the affected shoulder. The condition generally affects the glenohumeral joint, which is the joint at the end of the shoulder comprised of the socket of the shoulder blade and the ball of the arm bone. The cartilage between these two portions of the arm and shoulder is the site affected by postarthroscopic glenohumeral chondrolysis. As the cartilage begins to deteriorate due to the condition, the individual starts to experience the complications associated with the disorder.. Individuals diagnosed with postarthroscopic glenohumeral chondrolysis experience stiffness and pain in the shoulder that has been affected by the condition and in some cases, they can lose the ability to move or use the affected shoulder. The cartilage in the shoulder joint is what allows the joint to move freely and smoothly. As ...

Chondromalacia (otherwise known as chondromalacia patellae, anterior knee pain syndrome, patellofemoral disorder or runners knee) is caused by improper tracking of the kneecap over the femur. As a result, the cartilage under the kneecap becomes roughened and pain results when the knee is bent or straightened while bearing weight.

Discussion. Chondral cartilage lesions do not heal spontaneously and may progress to severe osteoarthritis. For cartilage repair, a variety of surgical techniques have been established over the years. Further research led to the development of current new one-step cell-free scaffold-assisted cartilage repair approaches based on the experience with scaffold materials in previous two-step autologous chondrocyte implantation procedures. Commercially available scaffold-based products for one-step chondral cartilage repair have been recently tested in first case series and showed promising clinical outcome in the short-term follow-up; however, medium- and long-term comparative studies are necessary to evaluate the regenerative potential of this new one-step cartilage repair procedure and to demonstrate its superiority over or adequacy to traditional approaches.. Conclusion. This critical review summarises the development from two-step cell-based autologous chondrocyte implantation procedures to new ...

Repair of cartilage damage with autologous chondrocyte transplantation (ACT) has become popular in clinical use during the past few years. Although clinical results have mostly been successful, several unanswered questions remain regarding the biological mechanism of the repair process. The aim of this study was to develop a goat model for ACT. The repair was not successful due to the graft delamination, but we characterize the subchondral changes seen after the procedure. A chondral lesion was created in 14 goat knees, operated on 1 month later with ACT, and covered with periosteum or a bioabsorbable poly-L/D-lactide scaffold. After 3 months, only two of the five lesions repaired with ACT showed partly hyaline-like repair tissue, and all lesions (n = 4) with the scaffold failed. Even though the lesions did not extend through the calcified cartilage, the bone volume and collagen organization of bone structure were decreased when assessed by quantitative polarized light microscopy. There was a ...

Articular cartilage defects in the knee have a poor intrinsic healing capacity and may lead to functional disability and osteoarthritis. Cartilage cell therapy using autologous chondrocyte implantation (ACI) has been established as the first advanced treatment therapy medicinal product. Although this technique has achieved good mid-term results, it is a costly and extensive two-stage procedure which is limited by the number of chondrocytes obtained by biopsy and the dedifferentiation resulting from the expansion phase. Therefore, there is a need for improvement. A new cartilage repair technique should aim at decreasing surgical trauma, lowering complexity, improving logistics and cost-effectiveness while retaining or improving clinical outcome. Direct contact between mesenchymal stromal cells (MSCs) and dedifferentiated articular chondrocytes in vitro showed improvement of the chondrogenic phenotype of dedifferentiated articular chondrocytes. In addition, preserving the pericellular matrix of ...

Any cartilage damage to the glenohumeral joint should be avoided, as these damages may result in osteoarthritis of the shoulder. To understand the pathomechanism leading to shoulder cartilage damage, we conducted a systematic review on the subject of articular cartilage lesions caused by traumas where non impression fracture of the subchondral bone is present. PubMed (MEDLINE), ScienceDirect (EMBASE, BIOBASE, BIOSIS Previews) and the COCHRANE database of systematic reviews were systematically scanned using a defined search strategy to identify relevant articles in this field of research. First selection was done based on abstracts according to specific criteria, where the methodological quality in selected full text articles was assessed by two reviewers. Agreement between raters was investigated using percentage agreement and Cohens Kappa statistic. The traumatic events were divided into two categories: 1) acute trauma which refers to any single impact situation which directly damages the articular

Another option is using the patients own cells, either cartilage cells or bone marrow stem cells, to attempt to re-grow new cartilage in the ulcer. This technique is called Autologous Chondrocyte Implantation (ACI). Typically this requires 2 separate operations, the first to harvest the cells, and the second to implant them. Culturing the cells usually takes between 3 to 6 weeks. The picture to the right shows ACI performed on a 3 cm square cartilage defect.. The implantation surgery is usually open traditional surgery, in which the cells are impregnated in a collagen scaffolding (that looks like a piece of wet tissue paper), and this is pasted into the cartilage defect. ...

A knee cartilage injury can occur through trauma, overuse or age related degeneration, ranging from softening of the cartilage to a tear.

One important injury-activated pathway involves the release of pericellular fibroblast growth factor-2 (FGF2) from the articular cartilage. Using a novel model of murine cartilage injury, and joints from surgically destabilized mice we examined the extent to which FGF2 contributes to the cellular gene response to injury. Femoral epiphyses from 5 week old wild type mice were avulsed into serum-free medium. Explant lysates were western blotted for phospho-ERK, phospho-p38 and phospho-JNK or were fixed for immunohistochemistry for nuclear translocation of p65 (indicative of NFκB activation). RNA was extracted from injured explants, rested explants stimulated with recombinant FGF2 or FGF18, or whole joints of either wild type or Fgf2-/- mice. RT-PCR was performed for a number of inflammatory response genes previously identified from a microarray analysis. Murine cartilage avulsion injury resulted in the rapid activation of the three mitogen activated kinase pathways as well as NFκB. Almost all ...

The term chondropenia indicates the early stage of degenerative cartilage disease, and it has been identified by carefully monitoring early-stage osteoarthritis (OA). Not only is it the loss of articular cartilage volume, but it is also a rearrangement of biomechanical, ultrastructural, biochemical and molecular properties typical of healthy cartilage tissue. Diagnosing OA at an early stage or an advanced stage is valuable in terms of clinical and therapeutic outcome. In fact degenerative phenomena are supported by a complex biochemical cascade which unbalances the extracellular matrix homeostasis, closely regulated by chondrocytes. In the first stage an intense inflammatory reaction is triggered: pro-catabolic cytokines such as IL-1β and TNF-α triggering matrix metalloproteases and aggrecanase (ADAMT-4 and 5), responsible for the early loss of ultrastructural components, such as type II collagen and aggrecan. In addition nitric oxide and reactive oxygen species modulate the physiopathology ...

© Springer International Publishing Switzerland 2017. Mechanical stress is an obligatory aetiological factor in the development of OA so understanding how tissues of the joint respond to mechanical injury is likely to inform our understanding of pathogenesis. Much is known about how vascular tissues respond to damage, a process that involves activation of platelets on the exposed endothelium and recruitment of leukocytes to the site of injury. The articular cartilage is avascular yet responds rapidly and strongly to a range of mechanical stresses including cutting, avulsion, impact loading and shearing. It does so by activating a number of mechanosensitive pathways mediated by release of molecules trapped within the pericellular matrix as well as by triggering mechanoreceptors at the cell surface. In this way injury drives a number of intracellular signalling pathways, leading to a broad range of cellular responses. These pathways appear to be relevant to the in vivo response to mechanical disruption

PURPOSE: The goal of the study was to report the prevalence of the lesions of the articular cartilage of the femoral condyles and tibial plateau in patients with a symptomatic anterior cruciate ligament (ACL)-deficient knee undergoing day-case arthroscopy. TYPE OF STUDY: Case series study. METHODS: We studied 378 skeletally mature patients (average age, 27.3 years; range, 16-50 years; 282 men and 84 women), part of a sample of 1,978 patients undergoing a primary knee arthroscopy between January 1986 and August 1993. The articular cartilage lesions were classified according to Outerbridge by a single observer. We assessed the relationship between time of injury and articular cartilage lesions and between meniscal lesions and articular cartilage lesions. RESULTS: A complete ACL tear was found in all 378 knees. Of these, 157 showed at least one lesion of the articular cartilage. The medial femoral condyle (MFC) showed the highest frequency of articular cartilage lesions, especially in the ...

Perichondritis is inflammation of the perichondrium, a layer of connective tissue which surrounds cartilage. A common form, auricular perichondritis (perichondritis auriculae) involves infection of the pinna due to infection of traumatic or surgical wound or the spread of inflammation into depth. It may lead to severe deformation of the pinna if not treated vigorously with IV antibiotics. The causative organism is usually Pseudomonas aeruginosa. A rare form is laryngeal perichondritis (perichondritis laryngis). It develops suddenly due to an injury, virulent organisms or compromised immune status of the host, and also affects cartilage of the larynx. This may result in deformations and stenoses.

Purpose: To evaluate the effectiveness and limitations of autologous osteochondral grafting for the treatment of articular cartilage defects in the knee. Methods: The subjects were 40 patients who had undergone autologous osteochondral grafting. Fifteen knees had cartilage defects combined with anterior cruciate ligament tears (ACL group), 15 knees had cartilage defects combined with osteoarthritis (OA group), and 10 knees had cartilage defects combined with osteochondral dissecans (OCD group). From one to five osteochondral pegs were harvested from the less-weight-bearing periphery of the articular surface of the femoral condyle and grafted to cartilage defects. The clinical results were assessed based on the Lysholm score and radiographic and magnetic resonance imaging (MRI) image assessment. Results: The median follow-up duration was 24 months (range from 12 to 41 months). The mean Lysholm score following treatment was improved in all groups. The patients who had cartilage defects combined ...

Autologous chondrocyte implantation (ACI) is the most widely used cell-based surgical procedure for the repair of articular cartilage defects. Challenges to successful ACI outcomes include limitation in defect size and geometry as well as inefficient cell retention. Second-generation ACI procedures have thus focused on developing three-dimensional constructs using native and synthetic biomaterials. Clinically significant and satisfactory results from applying autologous chondrocytes seeded in fibrin within a biodegradable polymeric material were recently reported. In the future, third-generation cell-based articular cartilage repair should focus on the use of chondroprogenitor cells and biofunctionalized biomaterials for more extensive and permanent repair.

Perichondritis is a condition characterized by pain, swelling and purulent discharge from the external ear, which may progress to a deformity of the pinna. The presence of co-morbidities such as diabetes mellitus may aggravate the situation. The main aetiological agent is Pseudomonas aeruginosa and treatment consists of antibiotics combined with surgical drainage of the ear. We present the case of a diabetic patient with recurrent perichondritis of the pinna treated with hyperbaric oxygen therapy, with successful healing. Hyperbaric oxygen therapy has proved beneficial as adjunctive therapy of lesions in diabetic patients with foot ulcers, acting in the regeneration of intracellular free radicals and promotion of wound-healing factors. Thus, owing to its mechanisms of action, its effect on other injuries such as perichondritis in diabetic patients may be beneficial and lead to improvement ...

Patients with glenohumeral chondrolysis encompass a wide age range and typically present within 12 months after a surgical intervention or other insult. They are often young and have fairly rapid progression of pain with limited range of motion, crepitus and mechanical catching.1 The pain may be out of proportion to the clinical findings, which could lead to an incorrect diagnosis of complex regional pain syndrome. The most common cause is surgery in which there has been violation of the articular cartilage, including placement of pins, screws, suture anchors and knots, usage of electrocautery, radiofrequency probes and YAG laser, and intraarticular administration of local anesthetics with pain pump, chlorhexidine, and gentian violet.2 In a retrospective cohort study of 375 patients that underwent shoulder arthroscopy 13% developed glenohumeral chondrolysis, and each one of those patients had received an intra-articular postoperative infusion of an anesthetic.3 The risk of glenohumeral ...

Cell therapeutics to treat cartilage defects include autologous chondrocyte implantation products. However, little is known on the correlation of cartilage cell transplant properties before implantation and their potency to regenerate cartilage tissue after implantation. In this study, an ex vivo human cartilage repair model was developed, consisting of human condyle chips in which a standardized subchondral cartilage defect was manually set, being representative of cartilage defects as treated in the clinic. This model was used to test the potency of a cartilage cell transplant. To do so, cartilage cell transplants (spheroids) were implanted into these defects in a clinical relevant dosage and the defect filling and tissue regeneration process was followed ex vivo for 12 weeks. Most importantly, before implantation, characteristics of spheroids from the same batch as used for the implantation were determined with respect to general spheroid characteristics, gene expression of the chondrogenic ...

A) In my particular instance, I dont think I have any major muscular imbalances. My personal theory is that the notion of strengthening the posterior chain for knee pain doesnt solely help because of muscle imbalance, but rather that people who have strong posterior chains usually have better biomechanic (ie. dont leg press a squat) and dont let their anterior chains get overworkedand tight (through indirect anterior stretching; you cant finish full hip extension if your anterior chain is out of wack).. B) I was tight in the first place because I was running 4-5 times a week, swimming 3 days a week, and fin swimming 2 days a week (Air Force). I neglected stretching. I wasnt as strict on my biomechanics either. Thats the first change to make. No knee valgus, no excessive knees over toes, etc.. C) You need to stretch/mobilize to not get tight. But you need to break up all that stiffness with the myofascial work to aid the mobilization. Its like peanut butter and jelly.. 3) The barbell, and ...

Maybe Im changing too many things up, but Ive also been doing some isometric holds that Naudi Aguilar recommends in some of this videos, making sure Im concentrating on a neutral pelvis while doing them. Ive said this before, but Im seeing some improvement. Ive also been dry needling myself, mostly get a twitch response from the vastus lateralis and rectus femoris on the affected side.. ...

Joint, or articular, cartilage covers the ends of bones and allows for joints to glide smoothly with minimal friction. Cartilage damage, or chondral defects, can be caused by acute trauma, such as a bad fall or sports-related injury, or by repetitive trauma, such as general wear over time. Unlike other tissues in the body, joint cartilage has no innate ability to repair itself, making any injury permanent. Left untreated, knee cartilage damage can deteriorate into debilitating osteoarthritis and chronic pain, ultimately necessitating a joint replacement procedure.. We estimate, based on internal research, that over 500,000 knee cartilage procedures are performed annually in the United States primarily in the form of debridement, microfracture, conventional autologous chondrocyte implantation (ACI) and osteochondral grafting. Debridement and microfracture procedures are the most frequently performed surgical procedures for the treatment of cartilage damage, accounting for an estimated 90% of all ...

Cartilage defects in the knee are often seen in young and active patients. There is a need for effective joint preserving treatments in patients suffering from cartilage defects, as untreated defects often lead to osteoarthritis. Within the last two decades, tissue engineering based techniques using a wide variety of polymers, cell sources, and signaling molecules have been evaluated. We start this review with basic background information on cartilage structure, its intrinsic repair, and an overview of the cartilage repair treatments from a historical perspective. Next, we thoroughly discuss polymer construct components and their current use in commercially available constructs. Finally, we provide an in-depth discussion about construct considerations such as degradation rates, cell sources, mechanical properties, joint homeostasis, and non-degradable/hybrid resurfacing techniques. As future prospects in cartilage repair, we foresee developments in three areas: first, further optimization of degradable

A knee cartilage injury is commonly seen in sporting activities. Symptoms of cartilage damage in knee can range from dull aching and swelling to lock knee.

Management of articular cartilage lesions is based on the concept that providing blood with mesenchymal stem cell precursors access to the lesion encourages healing by formation of fibrocartilage. Several marrow stimulating techniques have been described to achieve this. Abrasion arthroplasty involves uniform removal of subchondral bone until bleeding is achieved. This can be accomplished in the canine elbow by use of either a curette or burr attachment on a small joint shaver. The shaver is usually more rapid and efficient and generally just as accurate. Another marrow stimulating technique is microfracture. In this technique numerous microcracks are created in the subchondral bone plate with a specialized micropick to allow bleeding at the lesion surface.. Arthroplasty and Microfracture. Indications for abrasion arthroplasty or microfracture vary with the size and degree of cartilage loss. In general, lesions small to moderate size (1-2 cm in humans) can be treated with resurfacing techniques. ...

Cartilage problems are among the most common problems in bone and joint problems. Left untreated, may result in the development of osteoarthritis, with a big impact on the quality of life in the long term. The present-date treatment such as microfracture, autologous chondrocyte implantation has shown only a modest degree of success. Despite the variety of available techniques, the effectiveness of these in terms of preventing or delaying the development of osteoarthritis is questionable. Stem ce
