We describe and evaluate a computer algorithm that automatically develops a surgical plan for computer assisted mosaic arthroplasty, a technically demanding procedure in which a set of osteochondral plugs are transplanted from a non-load-bearing area of the joint to the site of a cartilage defect. We found that the algorithm produced plans that were at least as good as a human expert, had less ...

We reviewed, retrospectively, 13 patients who had undergone open anterograde autologous bone grafting of the talus for symptomatic osteochondral defects of the dome of the talus. The mean age of the seven men and six women was 38.4 years. The defects included the full thickness of articular cartilage, extended through the subchondral plate and were associated with subchondral cysts. Six patient...

We reviewed lesions of the femoral condyles seen in 5,000 knee arthroscopies, recording the findings and the age and sex of the patients. We were able to distinguish the characteristics of developing and late osteochondritis dissecans, acute and old osteochondral fractures, chondral separations, chondral flaps and idiopathic osteonecrosis, and suggest that these are separate distinct conditions...

Pigmented villonodular synovitis of the elbow is rare and even rarer in children. We report a case of pigmented villonodular synovitis of the elbow in a 6-year-old girl who underwent total synovectomy after the diagnosis was confirmed by biopsy. The osteochondral defect at the olecranon was filled with calcium phosphate bone paste. Two years after surgery, neither recurrence nor joint degenerat...

Knee cartilage or osteochondral lesions are common and challenging injuries. To date, most symptomatic lesions warrant surgical treatment. We present two cases of patients with knee osteochondral defects treated with a one-step surgical procedure consisting of an autologous-based matrix composed of healthy hyaline cartilage chips, mixed plasma poor-rich in platelets clot, and plasma rich in gro...

Regardless of their etiology, cartilage defects of articular joints remain one of the unsolved problems in medicine. Therefore, numerous techniques to enhance cartilage repair are under clinical or experimental investigation. In any serious approach experimental investigation should precede human application. If the decision is made to implement an animal model, which one should be used? What i...
