거골 골연골 병변의 자가 골연골 이식술의 임상 결과

Purpose: To evaluate clinical results of autologous osteochondral graft in osteochondral lesions of the talus. Materials and Methods: Twenty feet in twenty patients underwent osteochondral autologous transfer in the osteochondral lesions of the talus. Sixteen were men and four were women. The mean age was 40.8 years old. The mean follow up was 2 years 9 months. Eighteen cases were medial, one case was lateral and one case was both, respectively. The average duration of symptom was 4 years 3 months. AOFAS ankle/hindfoot score (AOFAS score), visual analogue scale (VAS), Lysholm knee score were evaluated preoperatively and at the final follow up. Results: Postoperative AOFAS score was 87.3 (range, 69-100), which was significantly improved from preoperative AOFAS score of 62.0 (p=0.000). Postoperative VAS was 2.9 (range, 0-7), which was significantly improved from preoperative VAS of 7.5 (p=0.000). Postoperative Lysholm knee score was 92.4 (range, 80-100). All osteotomy of medial malleolus was united by the 4th month after surgery. Postoperative VAS was conversely correlated with the follow up period (p=0.024). There was no complications associated with surgery. Conclusion: Autologous osteochondral grafts in osteochondral lesion of the talus demonstrated excellent results with a short-term follow up.
