Knee replacement surgery — also known as knee arthroplasty  can help relieve pain and restore function in severely diseased knee joints. The procedure involves cutting away damaged bone and cartilage from the thighbone, shinbone and kneecap and replacing it with an artificial joint (prosthesis) made of metal alloys, high-grade plastics and polymers.

The most common reason for knee replacement surgery is to relieve severe pain caused by osteoarthritis. People who need knee replacement surgery usually have problems walking, climbing stairs, and getting in and out of chairs. Some also have knee pain at rest.

When is the surgery performed?

Conditions that can damage the hip joint, such as:

• Incision is made in the front of the knee.
• The patella bone is everted to the side and the knee joint is visualized
• Specialized measurement instruments are used to cut the layers of both joint surfaces to recreate the joint line and knee alignment.
• The implants are fixed to the femur and tibia using bone cement.
• Stability is assessed and the wound is closed.

Knee replacement is one of the most commonly done surgery worldwide. Sometimes both the knees can be replaced in the same sitting depending on the patient and disease condition.
