Evaluation of success of a meniscus repair device for vertical unstable medial meniscus tears in ACL-reconstructed knees.

Abstract

We retrospectively reviewed the success of meniscus repair with the FasT-Fix meniscus repair device for vertical unstable medial meniscus tears at the time of anterior cruciate ligament (ACL) reconstruction. A repair failure was defined as patients having medial knee symptoms leading to a subsequent arthroscopy confirming a tear at the repair site. Objective follow-up was obtained on 27 patients at a mean of 3.1 years postoperatively (range, 2-5 years). Two of 22 repairs (9%) in the red-red vascular zone and 4 of 5 repairs (80%) in the red-white vascular zone retore at the repair site at an average of 9 months postoperatively (range, 3-20 months). The results of this study showed a high failure rate (22%) of unstable vertical medial meniscus repairs with ACL reconstruction, especially for repairs done to tears in the red-white vascular zone.
