Meniscal lesions associated with anterior cruciate ligament injury.
The menisci frequently are injured during anterior cruciate ligament (ACL) injury or degenerate in a period of several years. The meniscus, in addition to transferring force across the joint, prevents tibial displacement on the femur if the ACL is injured. Ten per cent to 30% of the peripheral meniscus has circulation; healing can occur if a tear communicates with this region. Arthroscopic partial meniscectomy in irreparable tears can be helpful in some patients with meniscus-derived complaints. Total meniscectomy should be avoided in ACL insufficient knees when possible. Accurate meniscal reattachment with ligamentous reconstruction should restore knee stability.
