What is osteoarthritis, knee?

Symptoms of OA of the knee arise from loss of the normal articulation between the femur and tibia or of the articular cartilage. They may worsen with age and change, and their severity can be greatly influenced by physical activity. The knee is always a major weight-bearing joint of the lower limb and joints of its upper limb (arm, wrist, etc.) are involved in the pathophysiology of OA of the knee.
