A “Short Isometric Construct” Reconstruction Technique for the Medial Collateral Ligament of the Knee

Recently there has been increased focus on the medial collateral ligament (MCL) and the role the medial ligament complex plays in preventing valgus and external rotation, especially in the setting of a combined ligament injury. Multiple surgical techniques purport to reproduce “normal anatomy”; however, only one technique addresses the deep MCL fibers and the prevention of external rotation. Thus we describe the “short isometric construct” MCL reconstruction which is stiffer than the anatomic reconstructions. The “short isometric construct” technique resists valgus throughout range of motion whereas its obliquity resists tibial external rotation, helping to reduce the risk of anterior cruciate ligament graft re-rupture.
