CASE
A 51-year-old patient with medial compartment osteoarthritis of the left knee underwent an osteotomy of the proximal aspect of the fibula. Gait kinematic data were collected before and after the surgery with use of an optical tracking system during level walking. A sharp increase of approximately 5° to 7° in femoral abduction and a 5° to 8° increase in femoral external rotation were exhibited at 3 months postsurgery. At 1 year postsurgery, femoral external rotation had increased by 3° to 5°. There was also an increase of distal femoral translation (approximately 2 to 10 mm).
CONCLUSION
An osteotomy of the proximal aspect of the fibula altered the kinematics by increasing valgus, femoral external rotation, and distal translation of the knee. These alterations may help reduce knee pain and improve early functional recovery.
病例
一名51岁的左膝内侧间室骨关节炎患者接受了腓骨近端截骨术。在平地上行走时，使用光学跟踪系统在手术前后收集步态运动学数据。术后3个月，股骨外展角度急剧增加约5°至7°，股骨外旋角度增加5°至8°。术后1年，股骨外旋增加了3°至5°。股骨远端平移也有所增加（约2至10毫米）。
结论
腓骨近端截骨术通过增加膝关节外翻、股骨外旋和远端平移改变了运动学。这些改变可能有助于减轻膝关节疼痛并促进早期功能恢复。
