Background:
Meniscal repair is the goal, whenever possible, for the treatment of meniscal injury. The purpose of this study was to evaluate the long-term clinical success of meniscal repair performed with a second-generation, all-inside repair device with a concomitant anterior cruciate ligament (ACL) reconstruction.
Methods:
This was a retrospective review of prospectively collected patients who underwent meniscal repair by a single surgeon using the all-inside FAST-FIX Meniscal Repair System (Smith & Nephew) in conjunction with a concurrent ACL reconstruction. Eighty-one meniscal repairs (81 patients) were identified: 59 medial repairs and 22 lateral repairs. Clinical failure was defined as repeat surgical intervention involving resection or revision repair. Clinical outcomes were assessed with the Knee injury and Osteoarthritis Outcome Score (KOOS), International Knee Documentation Committee (IKDC) score, and Marx Activity Rating Scale score.
Results:
Ten-year follow-up was obtained for 85% (69) of 81 patients. Nine patients (13% of 69) underwent a failed meniscal repair (6 medial, 3 lateral), corresponding to a failure rate of 12% (6 of 50) for medial repairs and 16% (3 of 19) for lateral repairs. The mean time to failure was 2.8 years (range, 1.2 to 5.6 years) for the medial repairs and 5.8 years (range, 4.2 to 7.0 years) for the lateral repairs (p = 0.002). There was no difference in mean patient age, sex, body mass index, graft type, or number of sutures utilized between successful repairs and failures. Postoperative KOOS and IKDC outcome scores significantly improved over baseline scores (p < 0.001). There was no significant difference in patient-reported outcomes at 10 years between the group with successful repairs and those who had a failed repair.
Conclusions:
This report of long-term follow-up results of primary second-generation, all-inside meniscal repair demonstrates its relative success when it is performed with concurrent ACL reconstruction. After a minimum follow-up of 10 years, 84% to 88% of the patients continued to demonstrate successful repair. Failure of medial meniscal repairs occurred significantly earlier compared with lateral meniscal repairs.
