Runner's knee

What is Runner's knee (Chondromalacia Patellae)?

Chondromalacia Patellae (CMP, patello-femoral pain syndrome or Runner's Knee) is a discomfort or dull pain in the knee or just under or around the knee. It is most common in young adults, soccer players, cyclists and runners. Either the knee cap has been damaged or put off-center by trauma, or the cartilage has been worn out on one side or completely.

Causes

CMP is caused by trauma or muscular imbalance in the upper leg through excessive force or training of a single muscle or joint, where certain muscles are putting more force on the joint than others. See also Iliotibial band syndrome.

Treatments

Strengthen your muscles by doing light cycling or swimming or zero-impact, low-intensity exercise.

Strengthen your thigh and inner quadriceps (Vastus Medialis) to balance the forces on your knee cap.

Do not over-train. See overtraining.

When lying down, don't allow your bodyweight to put pressure or shift your knee cap. Use a pillow to keep your legs slightly bent and your knee-caps in place.

Ensure that you have enough leg room in your car and at your desk.

Maintain good posture at all times. Avoid crossing your legs for long periods.

Avoid twisting the knee joint, when changing direction, while walking.

Avoid applying excessive weight on the affected joint. Lose weight if necessary.

Stretch your quads, iliotibial band, hamstrings, back and calves regularly.

Wear comfortable shoes.

Taping the patellae in place may aid recovery.
