Abstract
The purpose of this study was to determine the strain in the ACL and MCL under simulated athletic activities using a novel hybrid robotic/cadaveric simulator. Four cadaveric knees, with ACL and MCL instrumented with strain transducers, were tested under simulated jump landing conditions from a height of 30 cm with various degrees of valgus orientation (fixed hamstring and quadricep forces) and various Quadriceps (Q) and Hamstring (H) force levels (fixed degrees of valgus). The response of Anterior Cruciate Ligament (ACL) and Medial Collateral Ligament (MCL) were monitored and assessed during the dynamic loading conditions. 4 – 5 tests were completed for each cadaveric leg, totalling 48 – 64 total tests. Analysis of data revealed that muscle activation (Q&H), in anticipation of landing, reduces the ACL strain even under severe valgus orientations. However, MCL strain is not influenced heavily by muscle activation.
