Reconstruction of the Popliteomeniscal Fascicles for Treatment of Recurrent Subluxation of the Lateral Meniscus

Recurrent subluxation of the lateral meniscus is characterized by episodes of mechanical locking of the knee joint. To completely preclude the posterior segment of the lateral meniscus from undergoing anterior dislocation during deep knee flexion, the structures to which it is attached need to be relatively taut. The posterosuperior popliteomeniscal fascicle retains its tension during deep knee flexion; therefore, reconstruction of the posterosuperior and anteroinferior popliteomeniscal fascicles was performed with an autograft harvested from the iliotibial band. This technique provides stabilization of the posterior segment of the lateral meniscus during deep knee flexion without interfering with the normal movement of the lateral meniscus throughout the range of motion of the knee joint.
