Runner’s Knee (Patellofemoral Pain Syndrome)

Runner’s knee is common among runners, but other athletes, including walkers and bikers can be affected as well. It can result from overuse injury, direct trauma to the knee, misalignment, foot problems, and weak thigh muscles.

The most common complaint is aching knee pain around the kneecap, but people suffering from runner’s knee may also feel pain when bending the knee or walking downstairs. The knee may swell or make popping or grinding sensations.

Possible treatments include rest, medication, and physical therapy.
