Knee Replacement Specialist in India

A surgical procedure in which damaged parts of the knee joint are replaced with artificial parts.

The surgery is done by separating the muscles and ligaments around the knee to expose the inside of the joint. The ends of the thigh bone (femur) and the shin bone (tibia) are removed as is often the underside of the kneecap (patella). The artificial parts are then cemented into place.

The new knee typically has a metal shell on the end of the femur, a metal and plastic trough on the tibia, and sometimes a plastic button in the kneecap.

Total knee replacement may be done on people, usually over 55, whose knees have been damaged by arthritis, trauma, or other destructive diseases of the joint resulting in severe limiting knee pain and significant stiffness, instability (constant giving way) and deformity (lock-knees or bowlegs) of the knee.

The hip is a ‘ball and socket’ joint. This means that the caput of the femur fits in the acetabulum of the pelvis. The ‘ball’ is the femoral head which fits into the socket is the acetabulum of the pelvis. This ball and socket design is what allows the poly-axial movement seen at the hip. The hip is made up of the pelvis and the femur. The pelvis is formed by 3 bones; the ischium, ilium and pubis. The femur is the longest and strongest bone in the human body[7]. The acetabulum is cup-shaped providing the articular surface for the head of femur to move within. The head of the femur is gripped by the acetabulum beyond its maximum diameter. The caput of the femur and the inside of the acetabulum are covered with a layer of hyaline cartilage.

The top end of your upper arm bone is shaped like a ball. Muscles and ligaments hold this ball against a cup-shaped part of the shoulder bone. Surgeons usually replace the top of the upper arm bone with a long metal piece, inserted into your upper arm bone, that has a rounded head. If the cup-shaped surface of your shoulder bone that cradles your upper arm bone is also damaged, doctors smooth it and then cap it with a plastic or metal and plastic piece.

There are different types of elbow replacements, and components come in different sizes. There are also partial elbow replacements, which may be used in very specific situations. A discussion with your doctor will help to determine what type of elbow replacement is best for you.
