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.. 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 ...

© 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 ...
