Pain In The Kneecap When Jogging On A Treadmill

The pain in your kneecap when jogging on a treadmill is likely caused by overuse of the joint. But since the knee is such a complex structure, the overuse of this joint can contribute to a number of conditions that often fall under the name of "runner's knee." These conditions can range anywhere from patellofemoral pain syndrome to patellofemoral malalignment to patellar tendinitis.

Patellofemoral Pain Syndrome

Running can cause damage to the cartilage under your kneecap, resulting in what's known as patellofemoral pain syndrome. Also referred to as chondromalacia patella, the repetitive stress on the knee joint from a run can eventually cause the cartilage to break down. Resting and icing the knee can help reduce inflammation and lessen pain, while a knee brace can support and better align the joint, alleviating further irritation.

Patellofemoral Malalignment

Patellofemoral malalignment is the displacement of the patella in relation to the groove at the base of the femur. This displacement is often the result of weakness or tightness along the quadriceps muscles, but may also be caused by tight ligaments near the knee, flat feet or overly pronated knee joints. Stretching and strengthening the upper legs can correct this issue when caused by weakness or tightness. If the condition is a result of flat feet, an arch support may help keep the patella aligned during a run.

Patellar Tendinitis

Patellar tendinitis is an inflammation of the tendon connecting the kneecap to the shinbone. It's the result of repeated stress on the patellar tendon that causes small tears to develop within this connective tissue. Like patellofemoral pain syndrome, self-care measures help to improve this condition, so resting, icing and elevating the affected leg typically proves beneficial. You may also see an improvement in the pain by wrapping the pained knee.

Prevention

Warming up prior to your run may help eliminate some of the stress placed on the knees during more strenuous athletic pursuits. You may also reduce the chances of runner's knee by working in some strength training for the lower body. The added muscle can better support your knee joints, and thereby alleviate some of the strain. Stretching can improve flexibility, which may also reduce the chances of injury.

Recommendation

Talk to your doctor to determine the exact cause of patella pain. You may need to work with a physical therapist to establish an exercise routine as well as modify your running form to prevent reinjury. Also, make sure to swap old shoes for new ones as the miles increase.
