Knee Crepitus: We call crunching in the knee crepitus. It usually comes from problems under the kneecap. If the pain is located right in the center of the knee then the patella is the usual culprit. If the pain worsens going from sitting to standing or with stairs then i feel comfortable that the problem lies behind the patella. Strength training for your knee is the answer with weight training.
