Abstract
BACKGROUND: Return to sports rate of chronic meniscus repair concurrent with Anterior Cruciate Ligament (ACL) reconstruction remains unclear, especially there is no well-defined return to sports criteria for evaluation. The purpose of this retrospective study was to determine the success rate of chronic locked bucket-handle meniscal tear (BHMT) repair with concomitant ACL reconstruction. METHODS: This study includes 51 chronic ACL injury patients with a locked meniscal tear of at least 6 weeks who underwent surgery. All cases were treated with arthroscopic BHMT repair and ACL reconstruction between 2017 and 2020. Patient demograph-ics, chronicity, pre-operative, and intraoperative surgical variables which associated with return to sports were defined. BHMT was repaired with an all-in-side meniscus repair and/or combined repair procedure first, then an anatomic outside-in ACL reconstruction using a suspension device for femoral fixation was performed. Patients underwent same rehabilitation program with the goal of return-ing to sport at approximately 4-8 months. A modified return-to-sport criterion was performed in this study. RESULTS: Fifty-one patients with an average age of 27.4 (range 18-48) years were included in the study. The average time elapsed from the occurrence of locked knee symptoms to surgery was 10.5±4.4 weeks. The mean follow-up time was 25.3±4.5 months. Sig-nificant improvement was observed in all patient-reported outcomes from baseline to the final follow-up. The mean modified Lysholm knee score increased from 45.5 points to 91.5 at the final follow-up (p<0.001). The 43 out of 51 patients (84.3%) were return to their recreational activities (amateur sports). The mean time to return to sport was 5.9±0.8 (5-8) months. CONCLUSION: Majority of the patients who underwent ACL reconstruction with BHMT repair return to their pre-operative activity levels in 8 months. All neglected BHMTs with concomitant chronic ACL rupture should be repaired in a single-stage surgery if the half plane-concave shape of the menisci has been preserved regardless of the delay in time to surgery.
