What is the cause of osteoarthritis?
Osteoarthritis is the end result of cartilage wearing away on bones, usually due to cumulative damage to the joint. This leads to increased friction, clicking and locking up of the affected joint. Cartilage is important as it cushions the space between the bones and helps to form the joint. Once the cartilage wears away completely, there is usually bone-on-bone rubbing, which is very painful.
