Flexion contracture is a common deformity encountered during total knee arthroplasty. Most deformities are mild and can be passively corrected at the time of surgery. Severe fixed deformities require surgical correction with release of the contracted soft tissues and appropriate management of the femoral bone resection. The goal of surgery is to correct the contracture and bring the knee to full extension. After surgery, attention must be given to maintaining full extension during the rehabilitation phase. Residual or recurrent flexion contractures are not tolerated well by the patient and pose a functional disability.
屈曲挛缩是全膝关节置换术中常见的畸形。大多数畸形较轻，在手术时可被动矫正。严重的固定畸形需要手术矫正，松解挛缩的软组织并适当处理股骨截骨。手术的目标是矫正挛缩并使膝关节完全伸直。术后，在康复阶段必须注意保持完全伸直。残留或复发性屈曲挛缩患者难以耐受，会导致功能残疾。
