Knee joint replacement surgery may be total where both sides of the knee joint are replaced, or uni-compartmental where only one side of the knee joint is replaced. The procedure is performed by separating muscles and ligaments around the knee to expose the knee capsule, and then the inside of the joint.
Knee replacement is surgery for people with severe knee damage. Knee replacement can relieve pain and allow you to be more active. Your doctor may recommend it if you have knee pain and medicine and other treatments are not helping you anymore

What is a Knee Joint?

A joint is a special structure in the body where the ends of two or more bones meet. The knee is the largest joint in the body. The knee is made up of the lower end of the thigh bone (femur), which rotates on the upper end of the sin bone (tibia), and the knee cap ( patella), which glides in a groove on the end of the femur. The end of the bones are covered by glistening material called hyaline cartilage. The hyaline cartilage cushions the underlying bone from excessive force and allows the joint to glide freely without pain.

The joint is held together with ligaments to keep the joint stable. The joint is enclosed in a capsule with a smooth lining called the synovium. The synovium provides the lubrication ( synovial fluid), which helps reduce friction and wear in the joint. Surrounding muscles and tendons enable the joint to move in various directions and also keep it stable.

A joint usually contains dense, pad-like structures called menscii ( or cartilages) and fibre-like connecting tissue called ligaments. The cartilages and ligaments cushion the bones and stabilize the joint so that the joint can move easily without pain. Additional stability and the ability to control movement are provided by tendons and muscles which are attached to the bones on each side of the joint.
