Osteoarthritis of knee. X-ray image of a side view of the knee joint of a 70 year-old woman with osteoarthritis. The lower end of the femur (thigh bone) is seen at top, this joins to the upper end of the tibia (shin bone, lower image). In a normal knee joint, a clear space should be seen between the femur and tibia. Osteoarthritis has lead to the loss of intervening joint surface which consists of cartilage and lubricating fluid. The ends of the bones have become severely eroded. Osteoarthritis is the most common type of arthritis due mainly to wear and tear on joints in the elderly. Treatments include painkillers, physiotherapy or surgery in severe cases.
