Arthroscopic meniscal repair evaluated with repeat arthroscopy

Arthroscopic meniscal repair is a technically feasible approach to the treatment of meniscal tears in young active individuals. To evaluate this premise, we repaired 29 minisci in 27 patients and then arthroscoped their knees 3 months later. Repairs were limited to displaceable longitudinal tears. In 16 patients ligaments were intact. Eleven patients were anterior cruciate ligament deficient, six of whom underwent concomitant ACL reconstructions. In two patients, bicompartmental tears were encountered. Under arthroscopic control, using curved cannulae, horizontal mattress sutures of absorbable monofilament were placed across the tear, out through the capsule, and tied over the fascia, deep to the skin. No arthrotomies were performed, and all portions of the menisci could be reached with this method. Twenty-four of 29 repairs healed completely; 5 healed partially (30 to 50% healing). Four of the five failed repairs occurred in unstable anterior cruciate ligament deficient knees.
