BACKGROUND: Large osteochondral defects of the weight-bearing zones of the femoral condyles in young and active patients were treated by autologous transfer of the posterior femoral condyle. This technique is a salvage procedure and aims at pain-free mobility of patients. MATERIAL AND METHODS: Between July 1999 and December 2000, 18 patients were operated on. Sixteen patients were evaluated using the Lysholm score. X-rays were done, and eight individuals underwent magnetic resonance imaging (MRI) analysis. The average age at the date of surgery was 37.4 (15-59) years, and the mean follow-up time was 55.2 (46-62) months. The mean defect size was 5.4 cm(2) (3.1-7.1). Trauma or osteochondrosis dissecans was pathogenetic in 81%. RESULTS: The Lysholm score showed a significant (p=0.001) increase from a preoperative median of 65.0 to a postoperative median of 86.0 points. Fifteen patients returned to sport activities. X-rays showed a rounding of the osteotomy edge in 12 patients and a partial bone-dense remodelling of the posterior femoral condyle in 11 patients. All MRI examinations showed vital and congruent grafts. CONCLUSION: Thus, the procedure is recommended for treating large and deep focal osteochondral lesions in the weight-bearing zone of the femoral condyle.     «
