Knee joint replacement is a surgery to replace a knee joint with a man-made joint. The artificial joint is called a prosthesis.
Osteoarthritis in the knee is the most common reason for knee pain.
Arthritis can be a very painful disorder which may slow down your mobility and keep you from doing normal daily activities.
The prognosis or outcome for a total knee replacement is very good. The operation should decrease pain and improve your quality of life.
