Meniscus Repair With Simultaneous ACL Reconstruction: Clinical Outcomes，Failure Rates And Subsequent Processing

Study Overview
=================
Brief Summary
-----------------
Our study has explored the causes of failure of meniscus repair and investigated the clinical effects of partial meniscectomy when meniscus repair failed.

Detailed Description
-----------------
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.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The result of partial meniscus resection | Clinical signs were assessed after the surgery, including swelling of the joint, tenderness at the joint line, locked-in syndrome, and positive McMurray's sign. | Two years after the surgery | 
| International Knee Documentation Committee（IKDC）scores | The minimum is 0, the maximum is 100, and the higher the score, the better the result | Two years after the surgery | 
| Visual analog scale (VAS) scores | The minimum is 0, the maximum is 10, and the higher the score, the worse the result | Two years after the surgery | 
| Lysholm scores | The minimum is 0, the maximum is 100, and the higher the score, the better the result | Two years after the surgery |
