Understanding knee pain
Normal body movements rely on joints working smoothly and without pain – maintaining maximum joint function allows us to enjoy an active and fulfilling life. The knee is the largest and one of the most complex joints of the body, as well as the one most likely to be injured at some point during your lifetime.
The knee is responsible for a wide range of movements – from walking and running to turning and squatting. As long as the knee remains healthy, we often take its functioning for granted, not appreciating just how much we rely on it for our daily mobility. However when problems arise, the resultant pain and stiffness reduce the joint’s flexibility, impeding our ability to perform everyday activities.
Whilst the knee joint is made up of a number of moving elements – bones, cartilage, muscles, ligaments and tendons – the different causes of knee pain are actually relatively few in number. In general, most conditions arise from only a narrow range of injuries or disorders.
Some mechanical knee problems arise as a result of an injury or sudden movement that places too much stress on the joint, straining it beyond its normal range of movement. Arthritis is a common cause of knee pain arising from damage to the cartilage within the joint, although other conditions exist which can also cause pain or discomfort in this area.
