Does your knee pain prevent you from performing and enjoying everyday activities?

Osteoarthritis affects nearly 350 million people worldwide.1 It is a common condition in which cartilage breakdown around the joints causes your bones to rub together, and it is especially common in the knee joint, which carries most of the body’s weight. Symptoms include pain, swelling, and changes in appearance and function of the joint – which can contribute to loss of motion.

If other treatments, such as medication, therapy or injections, have proven ineffective, a total knee replacement may be the best way to get your life back.
