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.
外侧半月板复发性半脱位的特征是膝关节出现机械性锁定发作。为了在屈膝程度较深时完全防止外侧半月板后段向前脱位，其附着的结构需要相对紧绷。腘肌腱半月板后上束在屈膝程度较深时保持张力；因此，采用取自髂胫束的自体移植物对腘肌腱半月板后上束和前下束进行重建。该技术可在屈膝程度较深时稳定外侧半月板后段，而不会在膝关节整个活动范围内干扰外侧半月板的正常运动。
