Extension contracture of the knee is an increasingly recognized complication of severe femur fracture. Traditional management by Thompson quadricepsplasty may result in a variable return of knee flexion and the possibility of significant extension lag. The Judet technique of quadricepsplasty offers the advantages of a controlled, sequential release of the components limiting knee flexion and a reduced potential for iatrogenic quadriceps rupture or extension lag. Judet quadricepsplasty corrected severe bilateral extension contractures with excellent results at 17 months postoperatively in a 29-year-old man.
膝关节伸直挛缩是严重股骨骨折越来越常见的并发症。传统的汤普森股四头肌成形术治疗可能导致膝关节屈曲恢复程度不一，且有明显伸直滞后的可能。朱代股四头肌成形术具有可控、逐步松解限制膝关节屈曲的结构成分的优点，医源性股四头肌破裂或伸直滞后的可能性降低。朱代股四头肌成形术矫正了一名29岁男性严重的双侧伸直挛缩，术后17个月效果极佳。
