Research workers in Sweden have shown that full thickness defects in the articular cartilage of the knee may be repaired by transplantation of cultured chondrocytes (New England Journal of Medicine 1994;331:889-95). The chondrocytes were removed from the knees at arthroscopy, cultured for 14-21 days, and then injected into the defect and covered with a flap of periosteum. Two years after transplantation 14 of 16 patients with lesions of their femoral condyles had good to excellent results; the outcome was less encouraging in seven patients with patellar lesions, only two of whom had good results.
