Knee replacement surgery is performed to relieve pain caused by arthritis in the knee. Arthritis results in stiffness, inability to walk, weight loss, poor sleep, tenderness and difficulty moving the joint. While medication provides temporary relief from knee pain, knee replacement surgery offers a more permanent solution. There are two main types of knee replacement - total knee replacement which replaces the entire knee joint, and partial or half knee replacement which replaces only one side of the knee affected by arthritis. The surgery is performed by Dr. Santpure Sivakumar at his clinic in Aurangabad, Maharashtra, India.
