Functional Outcomes of Arthroscopic Combined Anterior Cruciate Ligament Reconstruction and Meniscal Repair: A Retrospective Analysis.

ABSTRACT: Purpose:To evaluate the outcomes of arthroscopic meniscal repair performed in combination with anterior cruciate ligament (ACL) repair. Methods:This study presents a case series of 34 patients who underwent repair of meniscal tears along with ACL reconstruction from 2014 to 2016. Cases of discoid meniscal lesions and combined or ligament injuries other than ACL injuries were excluded. Patients were followed up periodically, at 3, 6, 9, 12, and 24 months. Preoperative and postoperative functional evaluations were performed using visual analog scale, International Knee Documentation Committee, and Lysholm knee scores. Results:The mean age of the patients was 29.1 years (range, 17-44 years). The mean follow-up period was 18 ± 7.8 months (range, 6-24 months). Among the 34 individual knees, 1 patient (3%) underwent both medial and lateral meniscal repairs. Medial meniscal repair was performed in 20 knees (59%), whereas the lateral meniscus was repaired in 13 knees (38%). A longitudinal tear was the most common type of tear pattern, followed by radial (6 patients) and complex (3 patients) tear patterns. The radial and complex tears were treated with an additional partial meniscectomy. The mean International Knee Documentation Committee score was 38.46 preoperatively and improved to 80.30 at final postoperative follow-up (statistically significant difference, P < .01). The mean Lysholm score was 50.30 preoperatively and improved to 91.40 at final postoperative follow-up (statistically significant difference, P < .01). According to the Lysholm knee score, 31 patients (89%) had excellent or good results. The mean visual analog scale score decreased from 7.3 preoperatively to 2 postoperatively. The clinical success rate of the repairs was 89%. Of 35 repairs, 4 (11%) had retears. Conclusions:Arthroscopic meniscal repair along with ACL reconstruction provided predictable high rates of meniscal healing and yielded favorable functional and clinical results. Patient selection remains one of the most important prognostic factors. Level of Evidence:Level IV, therapeutic case series.

Project description:BackgroundWhen meniscal repair is performed during anterior cruciate ligament (ACL) reconstruction (ACLR), the effect of ACL graft type on meniscal repair outcomes is unclear.HypothesisThe authors hypothesized that meniscal repairs would fail at the lowest rate when concomitant ACLR was performed with bone--patellar tendon--bone (BTB) autograft.Study designCohort study; Level of evidence, 3.MethodsPatients who underwent meniscal repair at primary ACLR were identified from a longitudinal, prospective cohort. Meniscal repair failures, defined as any subsequent surgical procedure addressing the meniscus, were identified. A logistic regression model was built to assess the association of graft type, patient-specific factors, baseline Marx activity rating score, and meniscal repair location (medial or lateral) with repair failure at 6-year follow-up.ResultsA total of 646 patients were included. Grafts used included BTB autograft (55.7%), soft tissue autograft (33.9%), and various allografts (10.4%). We identified 101 patients (15.6%) with a documented meniscal repair failure. Failure occurred in 74 of 420 (17.6%) isolated medial meniscal repairs, 15 of 187 (8%) isolated lateral meniscal repairs, and 12 of 39 (30.7%) of combined medial and lateral meniscal repairs. Meniscal repair failure occurred in 13.9% of patients with BTB autografts, 17.4% of patients with soft tissue autografts, and 19.4% of patients with allografts. The odds of failure within 6 years of index surgery were increased more than 2-fold with allograft versus BTB autograft (odds ratio = 2.34 [95% confidence interval, 1.12-4.92]; P = .02). There was a trend toward increased meniscal repair failures with soft tissue versus BTB autografts (odds ratio = 1.41 [95% confidence interval, 0.87-2.30]; P = .17). The odds of failure were 68% higher with medial versus lateral repairs (P < .001). There was a significant relationship between baseline Marx activity level and the risk of subsequent meniscal repair failure; patients with either very low (0-1 points) or very high (15-16 points) baseline activity levels were at the highest risk (P = .004).ConclusionMeniscal repair location (medial vs lateral) and baseline activity level were the main drivers of meniscal repair outcomes. Graft type was ranked third, demonstrating that meniscal repairs performed with allograft were 2.3 times more likely to fail compared with BTB autograft. There was no significant difference in failure rates between BTB versus soft tissue autografts.RegistrationNCT00463099 (ClinicalTrials.gov identifier).
