内侧副韧带股骨止点深埋术治疗膝关节内侧松弛

Recessing femoral insertion of medial collateral ligament for medial laxity of the knee joint

目的 探讨膝关节内侧副韧带止点深埋术治疗膝关节内侧松弛的手术适应证和手术操作方法。 方法 1999年 11月～ 2 0 0 1年 12月 ,共收治 2 9例膝关节内侧松弛的患者 ,行内侧副韧带股骨止点深埋术 :游离内侧副韧带的股骨止点 ,连同止点骨块 (1.5cm× 1.5cm)在原位深埋0 .5cm ,并用螺钉固定。 结果 所有患者随访 3～ 2 7个月 ,平均 9个月。除 1例合并前交叉韧带下止点撕脱骨折外 ,其余患者膝关节内侧松弛均消失 ,膝关节功能正常。 结论 股骨止点深埋术对于治疗单纯膝关节内侧松弛、内侧分离在 0 .5cm以内患者疗效满意 ,手术操作简单。

Objective To introduce the indications and the operative techniques in recessing femoral insertion of the medial collateral ligament for medial laxity of the knee joint. Methods From November 1999 to December 2001, recessing femoral insertion of the medial collateral ligament was performed in 29 patients with medial laxity of the knee joint. Bone plug (1.5 cm×1.5 cm) and the femoral insertion of the free medial collateral ligament were recessed 0.5 cm and fixed in place with a screw. Results All the patients were followed up for 3-27 months (average 9 months). All patients got normal function of the knee joint without medial laxity except for one patient with avulsion fracture of tibial insertion of anterior cruciate ligament. Conclusions Recessing femoral insertion of the medial collateral ligament can be performed easily and is a good method for patients with medial laxity and medial isolation within 0.5 cm of the knee joint.
