OBJECTIVES: This study aimed to compare the biomechanical strength and stiffness of the native posteromedial and posterolateral meniscotibial ligament complex (MTLC) to suture anchor repair of the MTLC.
METHODS: Biomechanical testing was performed on 24 fresh-frozen pediatric human knees. Four conditions were tested: native posteromedial MTLC (n = 14), native posterolateral MTLC (n = 14), posteromedial MTLC repair (n = 5), and posterolateral MTLC repair (n = 5). Load to failure and stiffness were measured for all conditions.
RESULTS: The load to failure for the posteromedial suture anchor construct was significantly higher than that for the native MTLC (p < 0.01). The posterolateral suture anchor construct had a significantly greater stiffness than the native MTLC (p = 0.03). Posterolateral MTLC load to failure and posteromedial MTLC stiffness were similar between native tissue and suture-anchor repair. All native MTLCs failed at the meniscus-MTLC interface. The suture anchor groups had various failure modes, including suture pullout and breakage.
CONCLUSION: Suture anchor fixation can match or exceed the native tissue's load to failure. This study supports the viability of suture anchor-based posterior MTLC repairs of the medial and lateral meniscus in pediatric bone.
