Symptoms of Runner's Knee
Runner's knee results in pain experienced under the patella, or knee cap. This discomfort is most often experienced during activity such as running. Positions such as squatting and kneeling also result in anterior knee joint discomfort due to dysfunctional patellar tracking. Rubbing, grinding, and clicking noises are often heard with runner's knee.
