All About Knee Replacement Surgery

Knee replacement surgery, also known as total knee arthroplasty, is a medical procedure that involves the replacement of a damaged or worn knee joint with an artificial implant. This surgery is typically recommended for people who suffer from severe knee pain or mobility problems that cannot be effectively treated with non-surgical methods.

Adults of any age might need knee replacement surgery, but it is mostly done in people between 60-80 years.
