The arcuate ligament revisited: role of the poster olateral structures In providing static stability in the knee joint

摘要

Purpose To determine the involvement of the postero-lateral structures including the lateral collateral ligament, the popliteus muscle-tendon unit, the arcuate ligament (popliteofibular ligament, fabellofibular ligament, popli-teomeniscal fascicles, capsular arm of short head of the biceps femoris and anterolateral ligament) and the posterior cruciate ligament in providing restraint to excessive re-curvatum, tibial posterior translation and external tibial rotation at 90° of flexion.
