摘　　要：目的对人工全膝关节置换术(TKA)治疗单侧膝内翻合并屈曲挛缩畸形进行临床分析。方法对15例膝内翻(内翻角度5～20°)合并屈曲挛缩畸形(屈曲畸形角度>20°)患者行人工全膝关节置换术。分析术中软组织的松解、下肢力线的恢复以及术后双下肢的等长问题。结果术中除1例原屈曲挛缩角度60°者手术矫正后仍残留5°屈曲,其余14例术后均达到膝关节完全伸直。结论对于膝内翻合并屈曲挛缩畸形,股骨、胫骨要求对线准确,保证假体置入后股骨头中心、膝关节中心与踝关节中心位于一条直线,使力线得到矫正;软组织松解的平衡要求每完成一步都要进行测量,预防术后关节不稳;下肢长度要恢复等长,防止术后跛行。Objective To perform clinical analysis of total knee arthroplasty therapy for unilateral knee varus combined with flexion contracture deformity. Methods Fifteen cases of varus （varus angle of 5-20°） combined with flexion contracture （flexion deformity angle〉20°） underwent total knee arthroplasty. The release of soft tissue surgery,lower extremity alignment restoration and postoperative lower extremity length were analyzed. Results After surgery,one patient with preoperative 60~ flexion contracture improved to residual 5~ knee flexion. The other 14 patients achieved full extension. Conclusion For patients with knee varus combined with flexion contraeture deformity,alignment of the femur and tibia should be corrected to ensure the center of the femoral head, knee joint and ankle joint at the same line. The alignment should be corrected. Release of the soft tissue should be measured after each procedure is finished to prevent the instability of the joint after operation. The length of beth lower limbs should be restored equally to prevent limping after surgery.
