BACKGROUND: There are sparse data available regarding outcome of meniscal repair performed at the time of ACL reconstruction in the pediatric and adolescent population. PURPOSE: To review the results of meniscal repair performed at the time of ACL reconstruction in pediatric and adolescent patients. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: The records of all patients age 18 years or younger who underwent meniscal repair at the time of ACL reconstruction between 1990 and 2005 were reviewed. Ninety-nine patients (56 female, 43 male) with an average age of 16 years (range, 13-18) were included. Average injury to surgery interval was 107 days (range, 2-1109). Clinical outcomes were assessed at a mean of 8 years postoperatively (range, 2-19). A multivariate model was used to compare this cohort with a previously published cohort of patients with isolated meniscal tears. RESULTS: The clinical success rate of meniscal repair was 84% for simple tears, 59% for displaced bucket-handle tears, and 57% for complex tears (74% overall). Twenty-six menisci (26% overall) failed repair and 25 patients underwent repeat arthroscopic surgery (19 partial meniscectomies, 6 re-repairs). The average Tegner and International Knee Documentation Committee scores were 6.2 (range, 2-10) and 90.3 (range, 52-100), respectively. Risk factors for failure included complex and bucket-handle tear (P = .01), medial meniscal tears (P = .03), and skeletal immaturity (P = .01). Compared with isolated meniscal repairs in a similar pediatric and adolescent population, complex tears repaired in combination with ACL reconstruction did significantly better (57% vs 13%; P = .004). CONCLUSION: Clinically successful repair of meniscal tears treated at the time of ACL reconstruction in patients 18 years or younger depends on tear type, with complex and bucket-handle tears being negative prognostic factors. Complex tears have a higher rate of clinical success when repaired at the time of ACL reconstruction versus when repaired in isolation.
