Abstract

Background: Meniscal pathology in children and adolescents is now a common occurrence because of their ever-increasing participation in youth sports.

Purpose: To investigate the outcomes of arthroscopic meniscal repair in an adolescent cohort and analyze the variables that may affect outcomes, specifically the number of fixation sites utilized during repair.

Study design: Case series; Level of evidence, 4.

Methods: A retrospective review of all children and adolescents younger than 18 years who underwent arthroscopic meniscal repair at a single institution was performed. Patient characteristics, operative details (eg, tear pattern, tear location, method of repair, and number of fixation sites [determined based on the number of sutures used for repair]), and concomitant procedures were recorded.

Results: A total of 175 primary meniscal repairs met inclusion criteria and were analyzed. Of this cohort, 115 were able to be contacted and were included in the final study cohort. The mean follow-up was 41 months. The mean age of the children was 14.9 years, and 91 (79%) had concomitant anterior cruciate ligament reconstructions with their meniscal repair. The mean Pediatric International Knee Documentation Committee functional outcome score was 91 (range, 43-100), and the mean Lysholm functional outcome score was 91 (range, 47-100). Of the 115 meniscal repairs, there were a total of 19 reoperations (17%); 15 (13%) were because of meniscal repair failures. The only variable that statistically increased the risk of meniscal repair failure was low number of fixation sites, with the failure group having a mean of 1.79 sutures and the nonfailure group having a mean of 2.97 sutures (P = .03).

Conclusion: Successful meniscal repairs and a lower failure rate may be achieved with a greater number of fixation sites with promising results at a minimum 2-year follow-up. Validated functional outcome scores were good, with a 13% failure rate. Larger cohort, longer term, multicenter multisurgeon data are still needed to further elucidate the number of fixation sites needed when performing a meniscal repair in the pediatric and adolescent knee.
