MEASURING DYNAMIC KNEE MOTION DURING JUMP LANDING

The majority of anterior cruciate ligament (ACL) injuries in female athletes has been observed in noncontact situations such as jump landing. Theoretically, valgus and external rotation moments imposed to the knee joint will place ACL at high risk for injury (Olsen et al., 2004). Even though, it has been accepted that tibial and femoral rotation affects ACL tension, few studies have demonstrated tibial and femoral rotation angle in the relationship to neutral position. Therefore, the purpose of this study was to measure the tibial and femoral rotation angle during jump landing in female athletes
