LCL Tear
Signs and Symptoms

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