自体骨软骨移植治疗股骨髁大块骨软骨缺损

目的 探讨修复骨软骨缺损，恢复关节功能的途径。方法 取同侧髌骨外侧关节面的骨软骨块，自体移植到股骨髁大块骨软骨缺损区。根据Cincinati膝关节评分标准进行评估。本组共8例病人。男性6例，女性2例；平均年龄26岁；缺损面积260-788m^2，平均480mm^2。术后平均随访28个月。结果 通过对所得评分进行统计学处理。结果 显示术前术后有显著的统计学差别，术前评分为42分，随访结束后平均评分为77分。表示术后膝关节功能较术前有显著改善，部分病人可恢复正常的日常生活。结论 通过骨软骨自体移植的方法修复关节软骨缺损是一条值得深入研究的途径。

Segmental osteochondral defects of femoral condyles treated by osteochondral autograft

Objective]To explore the paths to repair the segmental articular osteochondral defects and recover the function of the joint. Through osteochondral autografts taken from the ipsilateral lateral patellar facet, 8 patients (6 males and 2 females; average age 26 years) with segmental osteochondral defects of the femoral condyle was treated. The average area of the defects was 480 mm2 (from 260 to 788 mm2). These patients were followed up with average followup of 28 months. According to the Cincinati knee scores, there was a significant change between pre- and post- operation statistically (from average preoperative score of 42 to average postoperative score of 77). The result showed that the postoperative function of knee was improved markedly and partial patient could live and work normally. Conclusion] By osteochondral autograft, the segmental osteochondral defects can be effectively treated. This path is worthy to further study.
