Abstract:
Objective To evaluate the possibility for the treatment of chondral defects on the femoral bearing surface with autologous osteochondral transplantation under arthroscopy. Methods There were 17 patients with cartilaginous surface defects, including 12 males and 5 females. The average age of patients was 29 years ranging from 18 to 45 years. The defects were located at 10 left knees and 7 right knees. The functional status of patients were evaluated according to the Brittberg-Peterson scoring scale system, the results were average 80.65?9.69 points ranging from 65 to 105. 3 patients had no an obvious history of trauma, but suffered from the rheumatoid disease; however, the other 14 patients had been injured at the knee joint with pain and followed with muscle atrophy on the thigh. 3 patients experienced interlocking, and 2 had snapping in their knee joints. All the 14 patients with traumatic history had only solitary lesion, the area of local cartilaginous defects at the bearing surface of the lateral femoral condyle was of 2.5-3.0 cm2; the local defects of the other 3 patients were located at the medial femoral condyle with defect area of 2.0-2.5 cm2, which was diagnosed either as chondomalacia or corruption. The procedures of the mosaicoplasty consisted of harvesting osteochondral cylinders from non-weight bearing surface of the knee and then implanting the grafts into the cartilaginous defects under arthroscopy. Results All the patients were followed up for 10 to 20 months (mean, 15 months). The joint mobility recovered to nearly normal. According to the Brittberg-Peterson system, 14 patients had score of 0, and 3 had scores of 2-3 because of mild pain. The follow-up MRI showed adequate cartilaginous coverage in the original lesions and excellent position of the cylindrical osteochondral grafts. Conclusion The autologous osteochondral mosaicplasty is proved to have good and reliable clinical results for the cartilaginous defects in the knee bearing surface.
