Sports Knee Injuries / The Knee
MCL & LCL Tear

The MCL connects the femur and tibia on the inner side (between the knees) and resists forces acting on the outer side of the knee, and the LCL connects the femur and tibia on the outside of the knee and resists forces acting on the inner side of the knee. The two ligaments provide support and stability to the knee. The MCL is more often injured than the LCL as injuries are often caused by a blow to the outer side of the knee (as seen in contact sports) that stretches and tears the ligaments on the inner side of the knee.

Initial symptoms of MCL and LCL tears include pain, stiffness, swelling and tenderness along the inner side or outside of the knee. In addition, the knee may feel unsteady or it may lock or catch.
