Distal Knee Medial Collateral Ligament Repair With Suture Augmentation

Abstract

The medial collateral ligament (MCL) is the most commonly injured ligament of the knee. Given its extra-articular location, the MCL has great healing capacity such that the mainstay of treatment for most injuries remains conservative management. However, certain injury patterns place patients and athletes at risk of residual valgus laxity, which may require delayed surgical care and prolonged time out from sports. As such, identifying the specific injuries known to place patients at risk for failure with nonoperative management is of paramount importance. Although controversy remains regarding the optimal treatment of grade III MCL injuries, it is generally accepted that MCL ruptures from the distal tibia attachment require operative fixation. This technique article with accompanying video provides a detailed description of a technique for repairing the distal MCL attachment with suture augmentation. There are several advantages associated with an augmented direct repair including early, safe rehabilitation; prevention of valgus instability; and avoiding the comorbidities associated with a larger reconstruction.
