Purpose

The Judet’s technique of quadricepsplasty for an extension contracture of the knee joint offers the benefit of a sequential and controlled release of the intrinsic and extrinsic soft tissue constituents restricting the knee flexion. The main principle of our study was to analyze the clinical as well as functional outcome and to assess an extension lag following Judet’s quadricepsplasty for the knee extension contracture deformity.

Materials and Methods

This is a retrospective cohort study comprises of thirty three patients, operated for extension contracture with Judet’s quadricepsplasty with the mean follow-up was 30 months. Knee range of motion of the operated knee was recorded preoperatively and at 6, 12 and 24 month follow-up after the surgery. Judet’s criteria were used to evaluate the outcomes following the procedure.

Results

92.42° (range, 60°–110°) of knee flexion was achieved after an average follow-up of 24 months compared to preoperative knee flexion was 14.09° (range 5°–25°), reflecting a 74.69° average improvement in knee flexion. Twelve patients had excellent results, nineteen had good results as per Judet’s criteria but there were no patients with extension lag. The two patients with fair results had superficial wound infection which healed without any further surgical intervention.

Conclusions

Judet’s quadricepsplasty offers sequential release without extension lag of the knee joint. Patients with the knee extension contractures deformity can be successfully managed with the Judet’s quadricepsplasty to gain useful knee motion and function.

Judet 的股四头肌成形术技术为膝关节伸展挛缩提供了出色的功能结果，且没有伸展滞后：33 名患者的回顾性队列

目的

Judet 的股四头肌成形术用于膝关节伸展挛缩，其优点是能够顺序且受控地释放限制膝关节弯曲的内在和外在软组织成分。我们研究的主要原则是分析临床和功能结果，并评估 Judet 股四头肌成形术治疗膝关节伸展挛缩畸形后的伸展滞后。

材料和方法

这是一项回顾性队列研究，由 33 名患者组成，他们因伸展挛缩而接受 Judet 股四头肌成形术，平均随访时间为 30 个月。术前以及术后6、12和24个月的随访时记录手术膝关节的膝关节活动度。 Judet 的标准用于评估手术后的结果。

结果

平均随访 24 个月后，膝关节屈曲度达到 92.42°（范围 60°–110°），与术前膝关节屈曲度 14.09°（范围 5°–25°）相比，膝关节平均改善 74.69°屈曲。 12 名患者获得了优异的结果，19 名患者根据 Judet 的标准获得了良好的结果，但没有患者出现伸展滞后。两名结果良好的患者出现浅表伤口感染，无需进一步手术干预即可愈合。
