The medial collateral ligament (MCL) is the primary restraint to valgus stress of the knee. Although the MCL has demonstrated an ability to reliably heal with conservative management, chronic medial instability has been well described following an isolated MCL injury or in combination with an anterior cruciate ligament (ACL) tear. When the MCL heals with persistent medial laxity surgical treatment may be necessary to prevent chronic medial instability and valgus overload of a reconstructed cruciate ligament. We present a simple technique for MCL recession that can be used for isolated MCL laxity as well as in chronic ACL/MCL knee injuries. This technique allows for secure fixation with bone-to-bone healing, avoids donor-site morbidity, maintains relative MCL isometry, and can be performed through a modest incision.
内侧副韧带（MCL）是膝关节外翻应力的主要限制结构。尽管MCL已被证明通过保守治疗能够可靠愈合，但孤立的MCL损伤或合并前交叉韧带（ACL）撕裂后，慢性内侧不稳定已被充分描述。当MCL愈合但仍存在持续性内侧松弛时，可能需要手术治疗以预防慢性内侧不稳定和重建交叉韧带的外翻过载。我们介绍一种简单的MCL后移技术，可用于孤立的MCL松弛以及慢性ACL/MCL膝关节损伤。该技术允许骨对骨愈合的牢固固定，避免供区并发症，维持MCL相对等长性，并且可通过适度切口进行操作。
