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

Abstract Recurrent subluxationof the lateral meniscusis characterized by episodes of mechanical locking of the knee joint. To completely preclude the posterior segment of the lateral meniscusfrom undergoing anterior dislocation during deep knee flexion, the structures to which it is attached need to be relatively taut. The posterosuperior popliteomeniscal fascicleretains its tension during deep knee flexion; therefore, reconstruction of the posterosuperior and anteroinferior popliteomeniscal fascicleswas performed with an autograft harvested from the iliotibial band. This technique provides stabilization of the posterior segment of the lateral meniscusduring deep knee flexion without interfering with the normal movement of the lateral meniscusthroughout the rangeof motionof the knee joint.
