Knee replacement, sometimes called total knee replacement surgery - https://bookinghealth.com/diseases/knee-replacement , is a surgery to replace the heavy weight-bearing ends of a knee joint to alleviate disability and pain. It's most commonly done for osteoarthritis (osteoarthrheic disorder), and for other knee ailments including rheumatoid arthritis, gout and psoriatic arthritis among others. People who get this kind of surgery have better chances of avoiding complications than those who don't. They recover faster and their hip and knee joints are more stabilized. This way even people with limited mobility can still enjoy an active lifestyle, sports and physical exercise.
