Arthritis or other joint problems.
The average hospital stay after knee joint replacement is usually three to five days. The vast majority of people who undergo knee joint replacement surgery have dramatic improvement. This improvement is most notable one month or more after surgery. The knee joint is the largest and most complex and therefore the most stressed joint in the body. It is this complexity and stress which can cause arthritis. Knee replacement surgery – whether total or partial – is an effective treatment for degenerative arthritis in the knee joint. After knee joint replacement, people are standing and moving the joint the day after surgery. At first, you may walk with the help of parallel bars, and then a walking device -- such as crutches, walker, or cane -- will be used until your knee is able to support your full body weight. Total knee replacement, or total knee arthroplasty, is a surgical procedure in which parts of the knee joint are replaced with artificial parts (prostheses) (image 1). INTRODUCTION. Total knee replacement, or total knee arthroplasty, is a surgical procedure in which parts of the knee joint are replaced with artificial parts (prostheses) (image 1). A normal knee functions as a hinge joint between the upper leg bone (femur) and the lower leg bones (tibia and fibula) (figure 1). You and your doctor may consider knee replacement surgery if you have a stiff, painful knee that makes it difficult to perform even the simplest of activities, and other treatments are no longer working. This surgery is generally reserved for people over age 50 who have severe osteoarthritis. Knee replacement is the most common joint replacement surgery. The main reason to have knee replacement surgery is to ease pain and disability caused by arthritis or other joint problems, while preserving movement. Less commonly, it is used to correct some kinds of knee deformity. Knee replacement surgery, also known as knee arthroplasty, is regarded as a modern surgical procedure that can accurately be described as knee resurfacing . This procedure entails restoring the weight bearing facade of the knee joint that is damaged, worn out, or diseased to relieve pain and movement disability.
