膝关节镜辅助下诊治股骨外髁骨软骨骨折的临床观察

Arthroscopic-assisted diagnosis and treatment in osteochondral fracture at external condyle of femur with the miniature incision

对8例股骨外髁骨软骨骨折患者，采用关节镜引导下结合微小切口复位可吸收棒内固定术进行治疗。术后随访8～12个月，平均（10±2）个月，Lysholm膝关节功能评分术前（42±4）分，术后（87±）分（P〈0．05）；膝关节活动范围术前（78±13）°，术后（125±9）°（P〈0．05）。关节镜引导下结合微小切口治疗股骨外髁骨软骨骨折，具有创伤小、并发症少、功能恢复好等优点。

Eight patients with osteochondral fracture of femur condyle were diagnosed and treated with arthroscopie-assisted miniature incision, the osteoehondral fracture blocks were fixed with the absorbable rod. All patients were followed-up for 8 to 12 months （mean 10 months）. The score of Lysholm scale of the knee function in preoperation was 42 ± 4, that in postoperation was 87 ± 6 ; the movement range of the knee joint in preoperation was （78 ± 13）°, that in postoperation was （125 ±9）°. The results indicate that arthroscopic-assisted surgery with the miniature incision for the treatment of osteocbondral fracture in external condyle of femur has the advantages of minimal trauma, less complication, well functional recovery and the comprehensive recovery of knee joint function.
