Background: There are few large-scale, long-term studies comparing medial meniscal repairs with or without concurrent anterior cruciate ligament (ACL) reconstruction. Methods: A total of 140 patients who underwent arthroscopic medial meniscal repair were divided into two groups: Group A, meniscus repair only and Group B, meniscus repair with concurrent ACL reconstruction. Clinical assessments in- cluded physical examination findings, Lysholm score, and the International Knee Documentation Committee (IKDC) form. Barret criteria were used for the clinical assessment of healing status. Magnetic resonance imaging (MRI)was obtained to confirmhealing and failure. Subgroups of participants were compared in terms of suture technique, type of tear, and location of tear. KT-2000 arthrometer testing was used for objective evaluation of anterior-posterior knee movement. Results: Mean follow-up duration was 61 (34-85) months. Clinical outcomes in both groups were significantly improved compared to baseline (P = .0.001 vs. P = 0.001); however, there was no significant between-group difference in postoperative Lysholm and IKDC scores (P = 0.830). The outcomes of three participants (seven percent) in Group A and 11 (11.3%) in Group B were considered as treatment failures (P = 0.55). Red-red zone tears had higher scores. Mean postoperative KT2000 arthrometer values of failed participants in Groups A and B were 4.66 mm (range, four to six) and 5.2 mm (range, two to seven), respectively. Conclusion: Concurrentmedialmeniscus repair and ACL reconstruction did not have clinical superiority over meniscus repair alone. Repairs in the red-red zone appeared to be associated with better outcomes. (C) 2017 Elsevier B.V. All rights reserved.
