A comparative chemical and histochemical study of the chondrodystrophoid and nonchondrodystrophoid canine intervertebral disc. (1/338)

The chemical composition of the intervertebral disc of 9-month-old chondrodystrophoid and nonchondrodystrophoid dogs was studied for collagen, noncollagenous protein and glycosaminoglycan. Content of these substances differed significantly between breeds. The differences were most marked in the nucleus pulposus; the noncollagenous protein content of the nonchondrodystrophoid breed was higher than in that of the chondrodystrophoid dogs. The total nitrogen value of the nonchondrodystrophoid nuclei pulposi was less than that of the corresponding chondrodystrophoid discs mainly because of the high collagen content of the latter discs. Histochemically, it was found that the nuclei pulposi of the nonchondrodystrophoid breed contains larger amounts of glycosaminoglycan than in the discs of the chondrodystrophoid breeds.  (+info)

Gender differences in knee cartilage volume as measured by magnetic resonance imaging. (2/338)

OBJECTIVE: The aim of this study was to analyze sex differences in knee cartilage volume. METHODS: Articulate cartilage volumes were determined by processing images acquired in the sagittal plane using T1-weighted fat saturation magnetic resonance on an independent work station. The knees of 28 subjects (17 male, 11 female) who underwent MRI for clinical indications (pain <3 months) but who had a normal X-ray and structurally normal MRI were examined. RESULTS: Males had significantly larger cartilage volumes than females, with difference in cartilage volume remaining statistically significant after adjusting for age, height, weight and bone volume. The differences for males relative to females were: femoral cartilage volume [4.1 ml 95% CI (2.0, 6.1)]; and patella cartilage volume [1.4 ml (0.2, 2.7)]. Although not statistically significant, the tibial cartilage volume also showed these sex differences. Exploratory analysis indicated an increasing gender difference with increasing age for patellar cartilage volume. CONCLUSION: Men have significantly larger knee cartilage volume than women, independent of body and bone size. The mechanisms for this will need to be determined.  (+info)

Immunohistochemical observations on the initial disorders of the epiphyseal growth plate in rats induced by high dose of vitamin A. (3/338)

The initial disorders of the epiphyseal growth plate cartilage were immunohistochemically examined in the proximal tibia of rats administered a high dose of vitamin A. Male Wistar rats were given 100,000 IU/100 g body weight/day of vitamin A for administration periods of 1 to 5 days (Day 1 to 5) from 4 weeks after birth or were given deionized water and used as control. They were sacrificed after 5-bromo-2'-deoxyuridine (BrdU) injection on Day 1 to Day 5 to remove the tibiae. The tibiae were processed for immunohistochemical examinations using antibodies against type I, II, X collagens and BrdU. BrdU-incorporated chondrocytes and type X collagen-negative area were reduced since Day 2 and type X collagen-positive area was reduced since Day 4. The cartilage matrix partially lost type II collagen and deposited type I collagen in the epiphyseal growth plate near the periosteum on Day 5. These findings suggest that a high dose of vitamin A initially disturbed the differentiation from resting to proliferating chondrocytes, subsequently inhibited the differentiation from proliferating to hypertrophic chondrocytes, caused the chondrocytes to deviate from the process of normal differentiation, and finally resulted in the deformation of the epiphyseal growth plate.  (+info)

Articular cartilage repair: are the intrinsic biological constraints undermining this process insuperable? (4/338)

This article reviews the experimental and clinical strategies currently in use or under development for the treatment of articular cartilage lesions. The vast majority of protocols under investigation pertain to the treatment of full-thickness defects (i.e., those which penetrate the subchondral bone and trabecular-bone spaces) rather than partial-thickness ones (i.e., those which are confined to the substance of articular cartilage tissue itself). This bias probably reflects the circumstance that partial-thickness defects do not heal spontaneously whereas full-thickness ones below a critical size do, albeit transiently. And it is, of course, a seemingly easier task to manipulate a process which is readily set in train than it is to overcome an induction-problem which Nature herself has not solved. Indeed, the reasons for this inert state of partial-thickness defects have only recently been elucidated, and these are briefly discussed. However, the main body of this review deals with the various transplantation concepts implemented for the repair of full-thickness defects. These fall into two broad categories: tissue-based (entailing the grafting of perichondrial, periosteal, cartilage or bone-cartilage material) and cell-based (utilizing chondroblasts, chondrocytes, periochondrial cells or mesenchymal stem cells). Cell-based systems are further subdivided according to whether cells are transplanted within a matrix (biodegradable, non-biodegradable or synthetic) or free in suspension. Thus far, the application of cell suspensions has always been combined with the grafting of a periosteal flap. The strengths and weaknesses of each concept are discussed.  (+info)

Biomechanics of integrative cartilage repair. (5/338)

Cartilage repair is required in a number of orthopaedic conditions and rheumatic diseases. From a macroscopic viewpoint, the complete repair of an articular cartilage defect requires integration of opposing cartilage surfaces or the integration of repair tissue with the surrounding host cartilage. However, integrative cartilage repair does not occur readily or predictably in vivo. Consideration of the 'integrative cartilage repair process', at least in the relatively early stages, as the formation of a adhesive suggests several biomechanical approaches for characterizing the properties of the repair tissue. Both strength of materials and fracture mechanics approaches for characterizing adhesives have recently been applied to the study of integrative cartilage repair. Experimental configurations, such as the single-lap adhesive test, have been adapted to determine the strength of the biological repair that occurs between sections of bovine cartilage during explant culture, as well as the strength of adhesive materials that are applied to opposing cartilage surfaces. A variety of fracture mechanics test procedures, such as the (modified) single edge notch, 'T' peel, dynamic shear, and trouser tear tests, have been used to assess Mode I, II, and III fracture toughness values of normal articular cartilage and, in some cases, cartilaginous tissue undergoing integrative repair. The relationships between adhesive biomechanical properties and underlying cellular and molecular processes during integrative cartilage repair remain to be elucidated. The determination of such relationships may allow the design of tissue engineering procedures to stimulate integrative cartilage repair.  (+info)

Concerning the ultrastructural origin of large-scale swelling in articular cartilage. (6/338)

The swelling behaviour of the general matrix of both normal and abnormally softened articular cartilage was investigated in the context of its relationship to the underlying subchondral bone, the articular surface, and with respect to the primary structural directions represented in its strongly anisotropic collagenous architecture. Swelling behaviours were compared by subjecting tissue specimens under different modes of constraint to a high swelling bathing solution of distilled water and comparing structural changes imaged at the macroscopic, microscopic and ultrastructural levels of resolution. Near zero swelling was observed in the isolated normal general matrix with minimal structural change. By contrast the similarly isolated softened general matrix exhibited large-scale swelling in both the transverse and radial directions. This difference in dimensional stability was attributed to fundamentally different levels of fibril interconnectivity between the 2 matrices. A model of structural transformation is proposed to accommodate fibrillar rearrangements associated with the large-scale swelling in the radial and transverse directions in the softened general matrix.  (+info)

Para-articular chondroma and osteochondroma of the infrapatellar fat pad: a report of three cases. (7/338)

We report three cases of para-articular chondroma and osteochondroma in the region of infrapatellar fat pad. All three lesions were resected and examined histologically. Two of them were primarily cartilaginous with a lobular pattern internally, and one uniformly osseous with peripheral cartilage. We conclude that these lesions are not the same. The former should be designated para-articular chondroma after Jaffe and the latter, osteochondroma.  (+info)

Premature termination codon in the aggrecan gene of nanomelia and its influence on mRNA transport and stability. (8/338)

AIM: To analyze the influence of the premature termination codon on mRNA transport and stability METHODS: Chondrocyte mRNA was isolated from homozygous and heterozygous nanomelic 17-days old embryos and examined by RT-PCR analysis. To analyze aggrecan mRNA stability, mRNA synthesis was inhibited with DRB [5,6 dichloro-1-(-D-ribofuranosyl benzimidazole)], a specific inhibitor of RNA polymerase II. Visualization of the aggrecan alleles was performed by in situ hybridization. RESULTS: The level of mutant aggrecan mRNA within the nucleus was equal to that of the control, but no mutant mRNA was observed in the cytoplasm. RT-PCR revealed that the mutant transcript was only detectable in the nucleus, compared with house-keeping glyceraldehyde-3-phosphate dehydrogenase (GAPDH) gene or collagen type II. A restriction site induced by premature termination codon TAA allowed the distinction of normal and mutant transcripts in chondrocytes derived from embryos heterozygous for the nanomelic mutation. After the treatment with DRB, identical decay rates were demonstrated for both transcripts within the heterozygous nucleus. In situ hybridization showed no abnormal mRNA accumulation. CONCLUSION: This is the first evidence suggesting that the transcript of the mRNA with the premature termination codon within an exon does exit the nucleus.  (+info)

TY - CHAP. T1 - Pure cartilage-based repair modalities of focal cartilage lesions. AU - Bárdos, T.. PY - 2013/6/1. Y1 - 2013/6/1. N2 - Focal cartilage lesions in diarthrodial joints have a limited capacity to heal, and repair techniques used at present are still unable to provide a universal solution. Osteochondral auto- and allografts are accepted and successful methods for the treatment of these lesions, but occasionally the osseal incorporation is delayed or insufficient and graft integration might be unsuccessful. Failure at this level generates a large osseos crater and the consequences can prove challenging. Until just a few years ago, it was a generally accepted dogma that when cartilage is detached from the subchondral bone it would fail to reintegrate to its bed and its surrounding cartilage. Recently, innovative approaches have been established to repair cartilage defects using pure cartilage-based implants, and so far they seem to have had considerable success. One of the available ...
This is a 12 year old Asian female with insidious onset of left hip pain 4 months in duration. At one point, her pain was so severe she could not bear weight and had to be picked up from school. She denies trauma to the hip. She could not participate in sports secondary to pain and also developed a limp with apparent leg length discrepancy secondary to pelvic obliquity and local muscle spasm. She complains of no other joint symptomatology. Her previous medical history is negative. ...
The joints consist of bones, cartilages (connective tissue) and synovial fluid. The role of cartilage is to reduce friction and optimize joint movement. Reduced synovial fluid production and cartilage degeneration leads to gradual degeneration of joints, resulting in increased friction, inflammation and thus reduced mobility and pain. This situation is called chondropathy or otherwise chondromalacia.. Chondropathy can affect any joint of the body, but the most common position is in the knee. It usually starts as a small destroy of a small area of cartilage either in the knee joint (knee chondropathy) and less often to the femur.. ...
The treatment of chondral defects of the leg can depend upon the area and size of the problem. In general, those that are about the end of the thigh bone, the femur, are those who are easiest to treat and have the best outcomes. Those around the tibia and kneecap (patella) are harder to treat and the results are not as reliable. Intended for those patients who have got a surface defect of the cartilage, with a flap or crack in it, a cleaning out collaflex zamiennik or shaving of a defect, called a chondroplasty, can be performed. This may be useful to alleviate the catching and painful symptoms from a cartilage flap, but they do not cure the underlying chondral defect. In effect, it is resurfacing the defect and that is important the sufferer end up being careful about returning to those activities which caused the cartilage flap in the first place or it could happen all over once again ...

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, ...
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,
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..

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 ...

© 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
The most important finding in the present case was that in addition to favourable clinical, functional and radiographic results, transformation of the cell-free COL1 scaffold took place. The biopsy showed no signs of remaining COL1, but instead showed COL2 with embedded vital chondrocytes.. Several studies have shown that the use of cell-free scaffolds leads to favourable results comparable to those for cell-seeded scaffolds in different animal models [10, 12]. Similar results regarding clinical and morphologic outcome after implantation of cell-free COL1 matrices in humans were recently published [13].. The clinical course for the present case is in line with these results. After implantation of the cell-free scaffold, clinical, functional and morphological assessment revealed continuing improvement over time. The deterioration in results at the latest follow-up can undoubtedly be attributed to the traumatic meniscal tear the patient suffered. This injury also explains the slight deterioration ...
Ive had it for a few years. If your doc prescribes physical therapy, you are going to concentrate on building the muscles in your inner thigh (these muscles support the alignment of the knee). The pain medicine, braces, etc. are just band aids. Only when I took working on muscle tone seriously did my symptoms subside. Also, do what you can to avoide significant weight gain. The dilemma is twofold if you do because 1. you are less likely to exercise and your muslce tone weakens, and 2. the additional weight makes it more difficult on your weight bearing joints, i.e. knees ...

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.

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 ...

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

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. ...

INTRODUCTION. Cartilaginous tissue of the articular surface is not vascularized and its nutrition is carried out by diffusion of substances found in synovial fluid, reason why articular cartilage lesions are difficult to heal (Lombelo et al., 2003). Several surgical and clinical treatments have been proposed over the years to repair articular lesions, including surgical excision of damaged tissue (Denoncourt et al., 1986), electrotherapy (Sousa et al., 2001), use of nutraceuticals (Henrotin et al., 2005), and mosaycplasty (Huntley et al., 2005). Nevertheless, all these procedures have resulted in a tissue with fibrocartilaginous repair, which does not have the same biomechanical properties of hyaline articular cartilage. In this context, cellular therapy may be used as an alternative to obtain the best morphophysiological repair result.. The clinical use of cultivated autologous chondrocyte implants began in 1987 (Jones and Peterson, 2006). At present, this method is used in human patients who ...

Most patients are able to return home on the same day as surgery or the following day. All patients will need someone to take them home and be with them on the night following surgery.. The anaesthetic will wear off after approximately 6 hours. Simple analgesia (pain killers) usually controls the pain and should be started before the anaesthetic has worn off. MENISECTOMY. For most patients undergoing meniscal cartilage surgery, where a damaged cartilage is trimmed (partial menisectomy), there is no reason to specifically restrict function other than to be guided by how the knee feels. Most patients who drive a car should be able to recommence this activity within 24-48 hours of the operation if they feel safe and confident to do so. Unless the surgeon advises otherwise it is important that patients build up their level of activity as soon as possible, accepting a little discomfort for a few weeks after surgery. Again, unless the surgeon advises otherwise, patients cannot cause any permananent ...

Usually, the first thing that happens is that the knee will immediately swell and cause tremendous pain. Athletic trainers and doctors are trained to physically examine the injury by pressing on the area where the meniscus is located. If tenderness is noted then is likely to be a tear.Patients can also note a tendency for the knee joint to pop or crack when the joint is moved. If the patients knee locks in place and will not straighten there may be impingement in the joint caused by a tear to the cartilage that interferes with natural movement ...

Cartilage is a type of hard, thick, slippery tissue that coats the ends of bones where they meet with other bones to form a joint. Cartilage lines the joint space between bones throughout the body, including the spine and the rib cage. It acts as a protective cushion between bones to absorb the stress applied to joints during movement.. Cartilage is made up of protein strands called collagen that form a tough, mesh-like framework. The mesh is filled with substances that hold water, much like a sponge. When weight is placed on cartilage, water is squeezed out of the mesh. When weight is taken off, the water returns. Cartilage does not contain blood vessels or nerves. ...
