LCL Tear
Signs and Symptoms

The most common symptoms of an LCL tear are pain, stiffness, swelling and tenderness along the outside part of the knee. Your knee may feel loose, as though it will give way under stress, or it may lock. More severe tears can cause numbness or weakness in the foot, which occurs in the peroneal nerve (located near the LCL) if it is stretched at the time of injury or squeezed by swelling of the surrounding tissues.
