Understanding the anatomy and biomechanics of the medial collateral ligament (MCL) is crucial in producing good outcomes after total knee arthroplasty. A solid grasp of the surgical techniques that address the MCL are necessary to ensure good coronal plane ligament balance. Furthermore, intraoperative injury to the MCL in total knee arthroplasty is an uncommon yet serious complication which often goes unrecognized. Loss of the integrity of the MCL can lead to instability, loosening, and accelerated polyethylene wear. There is still controversy regarding the ideal method of treatment of intraoperative MCL injuries with suggested treatment modalities ranging from conservative management to use of varus-valgus constrained implants.
了解内侧副韧带（MCL）的解剖结构和生物力学对于全膝关节置换术后获得良好效果至关重要。掌握处理 MCL 的手术技术对于确保良好的冠状面韧带平衡是必要的。此外，全膝关节置换术中对 MCL 的损伤虽然不常见但很严重，且常常被忽视。MCL 完整性的丧失可导致不稳定、松动和加速聚乙烯磨损。对于术中 MCL 损伤的理想治疗方法仍存在争议，建议的治疗方法从保守治疗到使用内外翻约束型植入物不等。
