Abstract	The geometry of the tibial plateau and the femoral condyles are emerging as key parameters to be studied as anterior cruciate ligament (ACL) injury risk factors. In this paper, we study the role of curved profile of the medial compartment of the tibia in a sagittal plane as a critical risk factor for the anterior cruciate ligament (ACL) injuries. The curvature of the mid-medial compartment of Tibia in 40 uninjured controls (21 women and 19 men) and 44 anterior cruciate ligament-injured cases (23 women and 21 men) were measured using magnetic resonance images and in-house matlab programming. We hypothesized that the Individuals with a less curved profile in the medial compartment of the tibia are at increased risk of suffering an anterior cruciate ligament injury compared to those with larger curved profiles. Based on t-tests, we established that the uninjured controls had larger curvature (p<0.05) compared to the injured cases. Biomechanically speaking a larger curvature of the tibia could prevent excessive sliding movement of femur with respect to the tibia, and thus could reduce the ACL strain. We suggest that future studies are needed to confirm this relationship and to evaluate the potential role of this curved profile of tibia in the risk of ACL injury.
