Meniscectomy and repair in the anterior cruciate ligament-deficient patient.

Meniscal injuries are frequently associated with acute injuries to the anterior cruciate ligament (ACL). With the passage of time, this frequency increases significantly. The management of the torn meniscus varies with the type of lesion and the patient's goals. When possible, meniscus repair combined with ACL reconstruction is recommended in young, athletically active patients. Repair may be accomplished by open or closed techniques. Because of significant risks associated with arthroscopic approaches, an outside-in type of repair has been devised. Overall, the clinical success approaches 90% if the ACL is reconstructed. Failure rates of 30% to 40% ensue if the knee remains unstable.
