What is a knee replacement?

It is a procedure performed to alleviate chronic knee pain, usually due to arthritis. It involves removing affected soft tissues and part of the knee bone, then replacing them with an implant or prosthetic joint components. [1]

There are basically two types of these procedures: the traditional knee replacement, and the minimally invasive knee replacement. 

A traditional knee replacement requires making a large skin incision compared to a minimally invasive knee replacement. It also involves the removal of a larger portion of the soft tissues like the muscles, ligaments, and tendons. A minimally invasive knee replacement is often preferred over traditional procedures. [2]

It can be performed on one or both sides. Most women develop osteoarthritis in the knee joints of both sides. A family history of osteoarthritis may increase the risk of bilateral knee replacement.

The disabling pain caused by osteoarthritis often forces people to give up the activities they enjoy. It may even prevent them from simple pleasures like taking a walk in the park. This surgery can enable people to resume their physical activities with less restrictions and discomfort. [8] [9]

The costs involved in treatment and post-operative care, like physical therapy, can also be reduced if a person plans knee surgery for both knees at the same time. 

What are the risks involved in knee replacement surgery?
