Osteoarthritis of the knee is a loss of cartilage between the thigh bone (femur), shin bone (tibia), and knee cap (patella). This can be caused by sudden injury or normal wear and tear. Factors that increase loss of cartilage can be increased weight, family history, or diabetes. Symptoms include joint stiffness, decreased range of motion, painful stairs, unsteady feeling of joint “giving out”. Goal: Improve flexion and extension, decrease inflammation and stiffness, increase knee and hip stabilization.
