Objectives: Meniscal injuries are among the most common orthopedic injuries in the United States. Meniscus repairs frequently achieve stability via capsular based repair techniques. Recent studies on meniscal ramp lesions, postero-lateral tears, and meniscus transplants demonstrate some shortcomings of meniscus suture techniques that incorporate menisco-capsular complex (MCC) repair. 1-3 Meniscus extrusion may also be affected by the function and integrity of the meniscus/menisco-tibial ligament complex (MTLC). 4 Inclusion of the MTLC in some repair/transplant constructs may produce more normal anatomic and biomechanical meniscus function, including the prevention of meniscus extrusion. However, the biomechanical properties of the MTCL in pediatric tissue has not been studied. Our objective was to evaluate the anatomy and biomechanical strength of the MTLC of the medial and lateral meniscus of pediatric knees. We hypothesized: 1) posterior anatomy of the medial and lateral knee would demonstrate a consistent recess or space between the posterior meniscus/MTLC complex and the MCC; and 2) the MTLC would demonstrate unique biomechanical characteristics between the posterior, middle, and anterior 1/3 zones of the medial and lateral meniscus. Methods: 14 fresh-frozen pediatric human knees from 10 donors (mean 7.5 years, range 5-10 years) were used in this study. The distance between the mensico-tibial ligament at the joint capsule and the height of the meniscus was measured with a depth gauge and digital caliper. We define this distance as the depth of the recess between MTLC and MCC (Fig. 1). Subsequently, the medial and lateral menisci were divided into approximate thirds with radial cuts extending through the menisco-tibial ligaments, creating anterior, central, and posterior testing zones for each meniscus (Fig. 2A). The posterior and anterior roots of each meniscus were released from the tibial attachment. Sandpaper was glued to each meniscus segment. Each tibial specimen was potted in fiberglass resin and mounted on an Instron 5944 test frame with a 2 kN load cell. Each meniscus/MTLC complex underwent 10 cycles of preconditioning from 3-5N at 10 mm/min followed by monotonic load to failure testing (Fig. 2B). The depth of recess, load-to-failure, and stiffness (maximum slope of load-displacement curve) were analyzed using linear mixed models with donor and limb as random factors and compartment (M/L) and position as fixed factors.
