Background: Meniscus repair performed during ACL reconstruction may fail and the subsequent treatment includes revision meniscal repair or partial meniscectomy.~Purpose: To retrospectively analyze the clinical outcomes of meniscus repair with simultaneous anterior cruciate ligament (ACL) reconstruction and explore the causes of failure of meniscus repair.~Methods: From May 2013 to July 2018, the clinical data of 165 patients who were treated with meniscus surgery and simultaneous ACL reconstruction by the same doctor, including 69 cases of meniscus repair (repair group) and 96 cases of partial meniscectomy (partial meniscectomy group), were retrospectively analyzed. The 69 patients of the repair group were divided into the nonfailure group (62 cases) and the failure group (7 cases) depending on the repair effect. The average follow-up period was 38 (±10.5) months. Postoperative outcomes of the repair group and the partial meniscectomy group were compared. General conditions and postoperative outcomes of the failure group and the nonfailure group were compared. Seven patients in the failure group who underwent second arthroscopy were followed up for 30 (±17.4) months, and their postoperative outcomes were summarized.
Our study has explored the causes of failure of meniscus repair and investigated the clinical effects of partial meniscectomy when meniscus repair failed.
