The knee is made up of the lower end of the thigh bone (femur), which rotates on the upper end of the shin bone (tibia), and the knee cap (patella), which slides in a groove on the lower end of the femur. Large ligaments attach to the femur and tibia to provide stability. The long thigh muscles (quadriceps) give strength to the knee. The joint surfaces where these three bones touch each other are covered with articular cartilage, a smooth substance that cushions the bones and enables them to move easily. A thin, smooth tissue liner called the synovial membrane covers all remaining surfaces of the knee.

Shoulder replacement is a surgical procedure in which all or part of the glenohumeral joint is replaced by a prosthetic implant. Such joint replacement surgery generally is conducted to relieve arthritis pain or fix severe physical joint damage. In shoulder replacement surgery, the damaged parts of the shoulder are removed and replaced with artificial components, called a prosthesis.

Broadly speaking a knee replacement surgery can be carried out either through the traditional approach, or newer minimally invasive approach (MIS), also known as quadriceps-sparing approach. It allows surgeons to insert the same artificial implant through a shorter incision. This surgical approach avoids trauma to the quadriceps muscle, which is the most important muscle group around the knee, thereby allowing quicker recovery time including walking and knee bending movements.

Joint replacement surgery is a combination of precision and surgical skills. The most important aspect of knee replacement surgery is to accurately restore the mechanical alignment of the leg. Computer navigation improves component position and alignment after knee replacement; thereby it is expected to further improve the results. The use of such a technology has certain additional benefits. Not only does the computer guide the accurate bony cuts, but they can also be carried out with a small incision, which is called ‘minimally invasive surgery’ (MIS). Computer navigation also reduces the risk of complications by providing constant guidance and monitoring during the surgery. However, there are few disadvantages of Computer Navigation. Technology is expensive and has long learning curve. If the bone mapping is not done accurately then there is high chances of error in the component final position.

The joint is one of the most important parts of our body that helps to make our move and perform our daily activities. A person who is facing advanced arthritis problems generally feels restriction in their movement and difficulties in performing daily activities. Robotic joint replacement surgery is one of the most effective solutions for them it helps to treat their problem without causing any additional problems.
