Ligaments are strong connective tissues that bind your bones together. In your knee joint, four ligaments work to keep your upper leg (femur) and lower leg (tibia and fibula) connected as your knee bends and extends. These ligaments are located on the inside and outside of your knee (tibial collateral ligament [MCL] and fibular collateral ligament [LCL]) and crossed-formed deep within your knee joint (anterior cruciate ligament [ACL] and posterior cruciate ligament [PCL]). In sports consisting of multi-directional movement or repetitive impact to the lower body, these ligaments are challenged to maintain proper knee alignment. In fact, many of the knee injuries that occur in a variety of sports come from ligaments being pulled passed their capacity and torn, often from an inward collapse of the knee (ACL and MCL tears). If you participate in a sport, it is wise to take the time to learn to decelerate, change direction, and land without compromising the knee joint. Doing so may help you avoid experiencing an injury during a competitive event. Regardless, some may be at a higher risk than others due to structural and biomechancial differences (size and shape of the femoral notch, degree of tibial torsion and femoral anteversion, joint laxity, etc).
