List the four major ligaments of the knee, describe the location of each and explain the role each one plays in providing stability to the joint.
ACL(anterior cruciate ligament)- located deep within the notch of the distal femur. Resists anterior translation and medial rotation of the tibia, in relation to the femur
PCL(posterior cruciate ligament)- located within the knee joint, originates from the lateral edge of the medial femoral condyle. Prevents the femur from sliding off the anterior edge of the tibia.
MCL(medial collateral ligament)- Located down the inner part of the knee, from the femur to the tibia. Prevents leg from over-extending inward.
LCL (lateral collateral ligament)- Located outside the knee. Keeps the knee stable as it moves through its motion
