Arthroscopic Repair for the Anterior Horn of the Lateral Meniscus With Suture Anchor.

The anterior horn tear of the lateral meniscus, often accompanied with local parameniscal cysts, is usually managed by cysts debridement and meniscus repair with the outside-in technique (OIT). However, a big gap between the meniscus and anterior capsule would be produced after cysts debridement and be difficult to be closed by the OIT. Or, the OIT would result in knee pain because of the overly tight knots. Therefore, we devised an anchor repair technique. Following the cysts resection, the anterior horn of the lateral meniscus (AHLM) is fixed at the anterolateral edge of the tibial plateau with 1 suture anchor, and then followed by suturing the AHLM with the surrounding synovium to promote healing. We recommend this technique as an alternative method for repairing an AHLM tear accompanied with local parameniscal cysts.
