Arthroscopic Release of the Deep Medial Collateral Ligament to Assist in Exposure of the Medial Tibiofemoral Compartment

Abstract

Arthroscopy of the knee is a widely used surgical procedure for addressing intra-articular pathology. In assessing the intra-articular structures, visualization is of paramount importance. The medial tibiofemoral compartment is often difficult to fully visualize in tight knees in which limited access can compromise surgical efficacy. Poor visualization can increase the possibility of a residual meniscal tear after attempted partial meniscectomy, as well as the possibility of iatrogenic chondral injury from arthroscopic instruments. We describe a technique that allows improved medial tibiofemoral visualization with release of the deep medial collateral ligament. We use standard arthroscopic portals, without the need for further incisions or stab holes and with minimal additional patient morbidity. This procedure allows easier exposure of the medial knee chondral surfaces and meniscus and easier use of arthroscopic instrumentation in the medial compartment.
