This study examines the relationship between meniscus tear presentations and failure rates following all-inside repair in isolation and in conjunction with an anterior cruciate ligament (ACL) reconstruction. Eighty seven consecutive patients undergoing all-inside meniscal repair at a single institution from July 2016 to June 2018 were retrospectively reviewed. Details of patient presentation, tear type and location, the presence or absence of simultaneous ACL reconstruction, and surgical repair details were recorded to evaluate the relationship between patient characteristics and the primary endpoint of repair failure. Patients were followed for an average of 2.7 ± 0.8 years. Three patients (3.4%) experienced 30-day complications including 1 deep vein thrombosis and 2 joint aspirations. Within the study time frame, 15 repairs (17.2%) failed, with 10 (11.5%) failing within one year of the initial procedure; the average time to failure was 12.3 ± 9.0 months. Patients undergoing concurrent ACL reconstruction were less likely to experience repair failure (9.7% vs. 36.0%, p = .009), while bucket-handle repairs were more likely to fail during the study period (45.0% vs. 9.0%, p = .001). These trends remained after controlling for tear location, body mass index, and number of sutures (ACL reconstruction Odds Ratio [OR]: 0.229, p = .029; Bucket-handle OR: 9.400, p = .003). Our findings suggest concurrent ACL reconstruction at the time of meniscal repair is associated with increased repair survival. The all-inside technique may be successfully used across a variety of tear types and locations, although further study of its efficacy in repairing bucket-handle tears is warranted.
