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. <br>RESULTS: The load-to-failure for the posteromedial suture anchor construct was significantly higher than 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 MTLC failed at the meniscus-MTLC interface. The suture anchor groups had various failure modes, including suture pullout and breakage. <br>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.<p> 10.1016/j.jisako.2025.100385 Suture anchor fixation of the pediatric posteromedial and posterolateral menisco-tibial ligament complex matches or exceeds native tissue strength: a cadaveric study 23801 Surgery 41222 document-rn43531 Knee Orthopedics
