Medial Collateral Ligament Reconstruction With Anteromedial Reinforcement for Medial and Anteromedial Rotatory Instability of the Knee

Abstract

Even though structures of the medial side of the knee have a high potential to heal without surgery, in some circumstances injuries of this region may lead to development of chronic medial and anteromedial rotatory instability (AMRI). In those circumstances, surgery should be performed. Current-day surgical techniques are focused on recreating the function of the main stabilizers of the medial side of the knee, which are the medial collateral ligament and the posterior oblique ligament, but they omit the role of the anteromedial capsule. Nonetheless, they are able to restore at most “near-native” biomechanics of the joint, are highly invasive, and require advanced skills in posteromedial knee surgery. Maybe we should take a look at chronic medial instability and AMRI from the other side? We present a minimally invasive reconstruction of the superficial medial collateral ligament with anteromedial reinforcement for the AMRI component. Level of evidence: 1 (knee) and 2 (collateral ligaments).
