Arthroscopic meniscus repair with a posterior incision.
The transarticular arthroscopic approach with a posterior incision provided a method of repairing more than 98% of unstable meniscus tears encountered between November 1983 and November 1986. A clinically stable bond was obtained in most of these tears with a subjective failure rate of 2% or less. There was a trend towards better healing of isolated meniscus repairs and lateral meniscus tears less than eight weeks old associated with ACL reconstruction when a blood clot injection was used to supplement the rasp abrasion of the parameniscal synovium. Healing of rim widths to 5 mm can be obtained with these methods. Indications for meniscus repair include all lateral meniscus tears and all medial meniscus tears except when repair of a stump would not replace 25% or more of the missing area. In our experience, this includes more than 98% of all unstable meniscus tears. Contraindications to meniscus repair include short (10 mm or less) stable tears, partial thickness (less than 50% of vertical height), and shallow radial tears (3 mm or less in depth). The posterior incision and popliteal retractor are necessary to protect the popliteal neurovascular structures.
