What is a knee replacment?

Answer 1

Knee joint replacement involves replacing part or all of a knee joint that has been damaged or worn away with a prosthesis (new joint made of metal and plastic) to reduce pain and improve function.

There are two types of knee joint replacement:

1) Partial Knee Replacement - where only one side of the knee joint is removed and replaced with a metal and plastic prosthesis. It is sometimes known as a Unicompartmental Knee Replacement (UKR) or Unicondylar Knee Arthroplasty

2) Total Knee Replacement - all the bone and cartilage at the bottom of the thigh bone (femur) and at the top of the shin bone (tibia) are removed. The entire knee joint is then replacement with a prosthesis (implant) made of metal and plastic. Also known as a TKR or Total Knee Arthroplasty.

Answer 2

Knee replacement surgery involves removing the damaged bone and cartilage at the end of the thigh bone and the top of the shin bone. It may also require replacing the kneecap surface.

The anatomy of the knee varies between individuals and between genders.

Damage to the knee joint can hamper simple daily activities such as walking. It could also cause visible deformities such as knock-knees or crepitus.

Joint replacement is an option for those who have suffered injury or conditions such as osteoarthritis. When the pain in the joints limits a person’s daily activities and does not seem to be responding to conservative treatment, joint replacement surgery is recommended. Several factors increase the risk of weakening your joints such as hereditary, trauma, obesity, repetitive injuries, etc. A joint replacement surgery should only be considered after all other treatments have failed to show desired results.

Answer 3

Knee replacement is where portions of the bones that form the knee joint are removed and replaced with artificial implants. It is performed primarily to relieve knee pain and stiffness caused by osteoarthritis.

Most people who get this surgery have advanced knee Arthritis, in which the knee cartilage is worn away and the surface of the knee becomes pitted, eroded, and uneven. This causes pain, stiffness, instability and a change in body alignment. Knee replacement surgery can also help some people who have a weakened knee joint caused by an injury or other condition.
