Posterior cruciate ligament:
The PCL (Posterior cruciate ligament) is located within the knee joint where it stabilizes the articulating bones, particularly the femur and the tibia, during movement. The PCL one of the four ligaments in the knee, and is the ligament that prevents the tibia (shin bone) from sliding too far backwards. Along with the ACL, which keeps the tibia from sliding too far forward, the PCL helps to maintain the tibia in position below the femur (thigh bone). It originates from the lateral edge of the medial femoral condyle and the roof of the intercondylar notch then, stretches at a posterior and lateral angle toward the posterior of the tibia just below its articular surface.
PCL tears typically occur during activities

The usual mechanism of injury for a PCL tear is either a Hyperextension force (e.g. where a player falls across the front of the knee causing it to straighten excessively) or due to a direct blow to the front of the shin bone with the knee in a bent position. Occasionally a PCL tear may occur during twisting movements, particularly when landing from a jump. (PhysioAdvisor) Injuries to the posterior cruciate ligament are not as common as other knee ligament injuries. In fact, they are often subtle and more difficult to evaluate than other ligament injuries in the knee. Many times a posterior cruciate ligament injury occurs along with injuries to other structures in the knee such as cartilage, other ligaments, and the …show more content…
The MCL is one of the most important ligaments of the knee because it gives the joint stability as a whole. The MCL prevents excessive twisting, and side to side movements of the knee. When these movements are excessive and beyond what the ligament can withstand, tearing to the MCL occurs. A MCL tear may range from a small partial tear resulting in minimal pain, to a complete rupture of the MCL resulting in significant pain and disability. (Ortho Info) MCL tears most commonly occur during activities in which excessive strain is placed on the MCL. This generally occurs suddenly due to a specific impact, however, may occur due to repetitive strain. Twisting of the knee and valgus forces upon the knee usually place stress on the
