The treatment of chondral defects of the knee can depend upon the location and size of the defect. to detect the most effective treatment option for primary talar osteochondral defects in adults. An osteochondral defect refers to a focal area of damage that involves both the cartilage and a piece of underlying bone. Trauma, osteochondritis dissecans, osteonecrosis, osteochondroses, and hereditary epiphyseal abnormalities can cause osteochondral lesions in the knee joint.25, 61, 62, 72 When an osteochondral defect persists in a weightbearing portion of the knee joint, degenerative arthritis of that compartment can result. The type of surgery that is most effective depends on the size, location and severity of the lesion. The use of minced articular cartilage for the repair of osteochondral articular cartilage defects of the knee is considered experimental and investigational. In the management of large cartilage defects, the two classically utilized cartilage restoration procedures are osteochondral allograft (OCA) … It is known from long-term followup studies, such as those conducted by Linden, 7 that osteochondritis dissecans diagnosed in adulthood is likely to lead to the development of early onset osteoarthritis. Commonly, multiple cylinders have to be transplanted to fill larger defects. Surgical treatment includes arthroscopic drilling of intact lesions, securing of cartilage flap lesions with pins or screws, drilling and replacement of cartilage plugs, stem cell transplantation, and in very difficult situation in adults joint replacement.

TREATMENT ALGORITHM FOR OSTEOCHONDRAL INJURIES OF THE KNEE. Physiotherapy plays a crucial role in rehabilitation and recovery following knee microfracture surgery. As a result, orthopedic research has concentrated on the development of alternative strategies. The fixed sutures on the femoral surface did not have much effect on the joints, and the patients did not feel any discomfort. Cartilage can be focally damaged, producing a “pot hole” in the joint surface, when the knee ligaments are injured. For instance, if the anterior cruciate ligament were to rupture, the tibia can slide forward (subluxate) and impact the femoral condyle (a so-called kissing contusion). Osteochondral autograft transplantation is used to address small to medium defects (1–4 cm 2), often with associated bone loss. The advantage of this treatment is that the patient's own cartilage is used to repair the damaged area. Chondral and osteochondral defects in the PF compartment are often encountered in clinical practice on advanced imaging studies and/or during arthroscopy. Unless the injury is extensive, it may take months, a year or even longer for symptoms to develop. Background: Mosaicplasty and fresh osteochondral allograft transplantation (OCA) are popular cartilage restoration techniques that involve the single-stage implantation of viable, mature hyaline cartilage-bone dowels into chondral lesions of the knee. This case report presents a massive OCD with displaced osteochondral fragment and loose body in the knee joint that occupied almost all of the weight bearing area of the medial femoral condyle and was treated with concomitant osteochondral autograft transplantation and fixation of displaced osteochondral fragment. James L. Chen, MD, (San Francisco, CA) provides a case presentation of a patient with an osteochondral lesion of the lateral femoral condyle. Most commonly, a surgeon will … We evaluated 13 patients who were treated with autologous osteochondral transplantation for a focal osteochondral knee lesion, with repeated bone scintigraphies of the donor and the recipient site up to 5 years after surgery. Those on the tibia and kneecap (patella) are harder to treat and the results are not as reliable. Available via license: CC BY 4.0. Address reprint requests to E.

For large osteochondral defects (> 9.6 cm2) of weightbearing areas of the knee, techniques established for smaller sized lesions such as drilling, microfracturing, and transplantation of osteochondral plugs (OATS, Mega-OATS) provide only insufficient clinical outcomes (12, 13). In general, those that are on the end of the thigh bone, the femur, are the ones that are easiest to treat and have the best outcomes. einstein. A chondral defect refers to a focal area of damage to the articular cartilage (the cartilage that lines the end of the bones). Treatment of osteochondral injuries and osteochondritis dissecans (OCD) is quite controversial and has received recent attention in the literature. Berruto M. et al. 2009;7(2 Pt 1):245-7. Damage to the surface of the knee joint is commonly caused by osteochondral lesions. Contraindications included patients with inflammatory arthritis, age below 35 or above … Current surgical treatments, such as microfractures, ACI and OAT, are the best options available, though it could be hard to increase the use of ACI and OAT because of similar results and higher costs, if compared with MF. Treatment options to restore joint congruity vary widely from nonoperative closed treatment to arthroscopic drilling, with or without fixation, to tissue transplantation or reconstructive procedures.
