A custom-designed six degrees of freedom (6DoF) test rig has been built to measure and compared the failure loads of native pig meniscus horns and those reattached using a novel bone tunnel technique.

The test rig allows precise manipulation of the tibia in all rotational and translational directions, closely replicating real joint motion. Native pig menisci were tested to failure using a torque wrench to establish baseline strength. In parallel, menisci in separate knee joints were surgically reattached with the new technique and subjected to the same loading conditions.

Key findings show that the reattached menisci withstood only 10% less load compared to healthy horns, with no observed damage to the meniscus or surrounding bone. These initial results indicate that the new bone tunnel technique provides a strong and reliable method for meniscus repair, closely replicating the performance of natural tissue.

This research lays the groundwork for future clinical studies and could significantly impact the treatment of meniscal injuries, improving joint stability and long-term patient outcomes.
