For sports like skiing, basketball and soccer with many stop and go motions, jumping can be the common cause for ACL and MCL injuries. The MCL is a ligament that provides stability to the inner knee whereas the ACL controls forward movement and rotation of the shin bone from the center of the knee.ĪCL and MCL tears are the most common knee injuries during sports or activities that involve twisting, bending and quick change of direction.

The ACL (anterior cruciate ligament) is located in the middle of your knee which can prevent the femur from sliding backward on the tibia, while MCL (Medial Collateral Ligament) is a band of tissue on the inside of your knee to connect your thigh bone and the bone of your lower leg which prevents your knee from bending inward. ACL and MCL are two out of four major knee ligaments that stabilize the knee.

People often ask about the difference between an ACL tear and an MCL tear.
