Knee flexion contractures can arise from posterior capsule arthrofibrosis secondary to trauma, surgery, or chronic degenerative disease. This leads to limited knee extension and increased mechanical stress on the contralateral joint. Depending on the severity of the contracture, a treatment option may include surgical release of the posterior capsule. Arthroscopic posterior capsular release has been reported previously to have excellent resolution of extension deficits with minimal risk of postoperative complications. These techniques typically use an array of instruments, including shavers, biters, or scissors to perform arthrolysis of the posteromedial and posterolateral capsules. Our primary objective is to present a modified arthroscopic surgical technique for percutaneous treatment of knee flexion contracture using a spinal needle to perform a posterior capsule release.
膝关节屈曲挛缩可由创伤、手术或慢性退行性疾病继发的后关节囊关节纤维组织增生引起。这会导致膝关节伸展受限，并增加对侧关节的机械应力。根据挛缩的严重程度，治疗选择可能包括后关节囊的手术松解。先前已有报道称，关节镜下后关节囊松解术在解决伸展功能障碍方面效果极佳，且术后并发症风险极小。这些技术通常使用一系列器械，包括刨刀、咬骨钳或剪刀来进行后内侧和后外侧关节囊的关节松解术。我们的主要目的是介绍一种改良的关节镜手术技术，用于经皮治疗膝关节屈曲挛缩，即使用脊椎穿刺针进行后关节囊松解。
