Sixteen quadricepsplasties performed for severe extension contractures of the knee were reviewed. Preoperatively all cases showed a severe extension contracture with an average of 23 degrees flexion. Only two patients had more than 30 degrees flexion preoperatively. The average improvement in knee flexion at follow-up was 69 degrees with 11 (68.7%) patients achieving a final flexion of 90 degrees or more. In four cases there was a 15 degrees loss of terminal active extension. In one case a rapid recurrence of the contracture was seen during the initial postoperative weeks. One patient developed a deep infection, and another an acute compartment syndrome.
回顾了16例因膝关节严重伸直挛缩而进行的股四头肌成形术。术前所有病例均表现为严重伸直挛缩,平均屈曲23度。术前仅有2例患者屈曲超过30度。随访时膝关节屈曲平均改善69度,11例(68.7%)患者最终屈曲达到90度或以上。4例患者终末主动伸直丧失15度。1例患者在术后最初几周出现挛缩快速复发。1例患者发生深部感染,另1例发生急性骨筋膜室综合征。
