What is Runner’s Knee?
Runner’s knee is caused by overuse and strain of the knee joint. Causes of runner’s knee include sports activities that require repetitive bending motion in the knee, usually running, and are commonly seen in sports medicine. This irritates the nerves in the kneecap or overstresses the tendons that connect muscle to bone in the knee joint.
Trauma to the knee (such as from a fall or direct blow) and weak thigh muscles can also cause runner’s knee symptoms.
Runner’s knee may also result from the misalignment of the bones in the joint, which can cause the weight of the body to be distributed unevenly in the knee.
Flat feet, also known as fallen arches, may contribute to runner’s knee by overstretching the tendons in the lower leg.

A healthcare provider may suggest special exercises or stretches that can help treat runner’s knee. For those with flat feet, arch supports may be inserted into the shoes to reduce the strain put on the tendons.
In severe cases, surgery may be necessary to remove damaged cartilage or correct the position of the kneecap.
