When To Consider Joint Replacement
A normal cartilage layer in joints allows nearly frictionless and pain-free movement. When it is damaged or diseased by arthritis, joints become stiff and painful. Every joint is enclosed by a fibrous tissue envelope or capsule with a smooth tissue lining, called the synovium. The synovium produces fluid that reduces friction and wear in a joint.
After examination, joint replacement is considered if other treatment options will not relieve the pain and disability. The materials used in a joint replacement are designed to enable it to move just like a natural joint.
