Osteoarthritis of knee. Illustration of the joint of a human knee affected by osteoarthritis. The cartilage (purple) at the end of the thigh bone (femur, at top) has worn away in patches. Irregular bony outgrowths, called osteophytes, have grown at the top of the shin bone (tibia). This picture shows the kneecap (patella) hanging loose to reveal the joint. The fibrous purple tissues are tendons and ligaments, which hold muscles and bones together inside joints. Osteo- arthritis results from wear and tear of joints. It is most common in the elderly and obese. Deterior- ation of joints causes pain, stiffness and lack of mobility. Treatment includes drugs and surgery.
