Knee Pain: Common Cause
The most common cause of chronic knee pain is chondromalacia patella, a condition which develops due to the softening of the cartilage beneath the knee cap (patella). The cartilage breaks down and the knee cap rubs against the thigh bone when the knee bends.
The process of this breakdown in cartilage is sometimes called patellofemoral syndrome and the rate of onset is increased by trauma, overuse or if abnormal forces are applied to the knee joint. Activities such as skiing, running, cycling and playing football can increase the pain felt by such a condition.
Apart from pain at the front and side of the knee, the condition is made worse when running, jumping, climbing stairs or when kneeling. 
A grating or grinding sensation may also be felt when the knee is extended.
X-rays of a knee with this condition may show a slight displacement of the knee cap. Therefore exercises designed to strengthen the muscle groups around the knee and restore normal alignment of the knee cap can help to reduce pain.
Assistance to realign the knee cap during exercise can be found in the form of a patella brace.
