Understanding Runner’s Knee: Causes, Symptoms, Treatment
Runner’s knee is a common term for pain felt around or behind the kneecap, especially during activities like running, squatting, climbing stairs, or prolonged sitting. The most common cause is patellofemoral pain syndrome (PFPS), a condition that occurs when the kneecap (patella) does not move smoothly along the groove of the thigh bone (femur). This can lead to irritation, inflammation, and discomfort in the front of the knee.
Although it’s often associated with running, runner’s knee can affect anyone, especially those who engage in repetitive knee-bending motions. Symptoms typically include a dull, aching pain around the kneecap, worsened by activity or sitting for long periods. Some people may also experience a grinding or popping sensation in the knee or mild swelling.
Runner’s knee can be caused by a combination of factors such as overuse, poor alignment of the leg or kneecap, muscle imbalances in the hips or thighs, or previous injury. Weakness in the surrounding muscles can also contribute to abnormal kneecap tracking.
Diagnosis is based on physical examination and activity history. Imaging such as X-rays may be used to rule out other knee conditions but is often not required for PFPS.
Treatment usually includes rest, activity modification, physical therapy to strengthen and balance the muscles around the knee and hip, and the use of orthotics or knee supports if needed. Most people recover well with conservative care. In rare cases where symptoms persist, surgical options may be considered.
