Abstrakt: Background: Several studies have demonstrated suture repair of ramp lesions of the medial meniscus via a posteromedial approach was associated with a significantly lower rate of secondary meniscectomy. However, these studies are not long-term and highlight the need for extended follow-up research to better understand the outcomes over a more extended period. Purpose: To evaluate the long-term results and reoperation rate for the failure of arthroscopic all-inside suture repair of ramp lesions of the medial meniscus via a posteromedial approach during anterior cruciate ligament (ACL) reconstruction. Study Design: Case series; Level of evidence, 4. Methods: All patients who underwent all-inside suture repair of the posterior segment of the medial meniscus (ramp lesion) via a posteromedial approach during ACL reconstruction at a minimum follow-up of 10 years were included in the study. Side-to-side anterior laxity was assessed preoperatively and postoperatively. Pre- and postoperative functional assessment was based on the subjective International Knee Documentation Committee score for activities of daily living and the Tegner activity scale for sporting ability. Reinterventions for meniscal repair failure and other complications were also recorded at the last follow-up. Results: A total of 81 patients met the inclusion criteria for this study. Two patients had an ACL graft rupture with a new ramp lesion and were excluded from the analysis. Additionally, 15 patients were lost to follow-up, leaving a total of 64 patients in the final analysis. The mean follow-up was 124.8 months (range, 122.4-128.4 months). Mean side-to-side difference in anterior laxity significantly improved from 7.4 ± 1.5 mm (range, 5-12 mm) to 0.4 ± 1.3 mm (range, –3 to 4 mm) (P =.01). The mean subjective International Knee Documentation Committee score increased from 64.3 ± 13.4 (range, 34-92) before the operation to 91.1 ± 10.1 (range, 49-100) at the last follow-up (P =.001). The Tegner activity scale score at the last follow-up (6.3 ± 1.6) was lower than that before the trauma (7.1 ± 1.6) (P =.02). Fourteen patients (21.9%) had a failed meniscal repair and were reoperated. The mean time from initial repair to reoperation was 64.5 months (range, 13-126 months), and the median was 60.6 months. The multivariate analysis, including parameters such as lateral tenodesis (hazard ratio [HR], 1.62; P =.50), preoperative Tegner score (HR, 1.66; P =.41), preoperative laxity (HR, 1.75; P =.35), age at surgery (HR, 1.02; P =.97), and number of sutures (HR, 2.38; P =.19), did not reveal any factors associated with suture failure. Conclusion: The results show that arthroscopic repair of ramp lesions of the medial meniscus during ACL reconstruction using a posteromedial approach has a high failure rate at the 10-year follow-up, with half of these suture failures occurring within 5 years after the initial repair.
