These injuries are quite prevalent, affecting 1 in 3000 Americans. Studies have shown female athletes are two-to-eight times more susceptible to ACL injuries than their male counterparts. ACL injuries are devastating to young athletes and often require a year of rehabilitation and pose a significantly greater risk for developing knee osteoarthritis. Many advances have been made with regard to surgical instrumentation and techniques, as well as rehabilitation programs, but none of these improvements have been proven to reduce the odds of developing osteoarthritis after ACL injury. The aims of the current study were to evaluate cadaveric knee kinematics to better understand ACL injury modalities.In this study, a total of 18 cadaveric knee specimens (age 44 +/- 8 years, 10 female and 8 male, 10 right and 8 left limbs) were tested under 65 loading conditions with and without Tekscan digital pressure sensors inserted between the tibial plateau and the meniscus. The tests were performed on a force couple testing system (FCTS) with simulated quadriceps (300 N) and hamstrings (180 N) muscle loads along with a joint compressive force (150 N). Similar trends were observed between knee kinematics obtained from this study and results obtained from previous studies. No significant differences in knee kinematics were observed between the specimens with and without Tekscan sensors. This study suggests the FCTS is a validated method for investigating in vitro knee kinematics and biomechanics.","abstract_html":"Anterior cruciate ligament injuries are severe sports injuries which tend to occur in younger populations.
