Percutaneous Arthroscopic Assisted Knee Medial Collateral Ligament Repair

摘要

Medial collateral ligament (MCL) injuries are commonly encountered alongside anterior cruciate ligament injuries. Treatment modalities have ranged from conservative management to surgical repair, augmentation, and reconstruction. Various reports have reported residual valgus instability, especially in higher-grade injuries that have been treated conservatively. The MCL provides valgus stability but also is an element of anterior stability to the tibia in addition to the anterior cruciate ligament. In addition, meniscal “lift-off” and “floating” have been described as consequences after MCL injuries, and meniscal dysfunction has been shown to lead to accelerated joint degeneration; therefore, all efforts should be made to treat these injuries adequately. We describe a simple, minimally invasive technique that involves suturing the deep MCL to the medial joint capsule, allowing better MCL healing, causing less soft-tissue scarring, and preventing meniscal extrusion.
