Patellofemoral Pain (Runner's Knee)
This condition is characterized by a dull or aching pain around or under the knee cap. Pain typically occurs when walking up or down stairs, squatting, kneeling and sitting with knees bent for an extended period of time. It is usually caused by any of the following: overuse of the joint, partial or complete dislocation of the kneecap, flat feet, a misalignment of the kneecap's position, and tight, weak or imbalanced thigh muscles.
Prevention methods include staying in decent shape, using proper running form, using proper running gear, and increasing training at a steady, healthy pace. Physical therapy will encompass exercises to strengthen knee, increase mobility as well as flexibility.
