Hip replacement is surgery for people with severe hip damage. When you have a hip replacement, the surgeon removes damaged cartilage and bone from your hip joint and replaces them with new, man-made parts. This can relieve pain, help your hip joint work better, and improve your walking and other movements. Your doctor may recommend it if you have hip damage and pain, and physical therapy, medicines and exercise don't help.
The most common problem after surgery is hip dislocation. Because a man-made hip is smaller than the original joint, the ball can come out of its socket. The surgery can also cause blood clots and infections. After a hip replacement, you might need to avoid certain activities, such as jogging and high-impact sports.

'''Hip replacement''' is the most successful, cheapest and safest form of replacement surgery. The first artificial hips were inserted in the 1930s, made of steel or chrome. They were better than arthritis but had a number of drawbacks. The main problem being that the articulating surfaces could not be lubrication by the body, leading to wear and loosening and hence the need to replace the joint again (known as revision operations). Attempts to use teflon produced joints that caused osteolysis and wore out within two years. The modern artificial joint owes much to the work of John Charnley at the Manchester Royal Infirmary; his work in the field of tribology resulted in a design that completely replaced the other designs by the 1970s. Charnley's design was a three-parter: 1: a metal (originally Stainless Steel) femoral component, 2: a plastic polyethylene acetabular component, both of which were fixed to the bone using 3: special bone cement. The replacement joint, which was known as the Low Friction Arthroplasty, was lubricated with synovial fluid. The small femoral head (22.25mm) produced wear issues which made it suitable only for sedentary patients, but - on the plus side - a huge reduction in resulting friction led to excellent clinical results. For over two decades, the Charnley Low Friction Arthroplasty design was the most used system in the world, far surpassing the other available options (like McKee and Ring). In the last decade several evolutionary improvements have been made in the total hip replacement procedure and prosthesis. Many hip implants are made of a ceramic material rather than polyethylene, which some research indicates dramatically reduces joint wear. Metal-on-metal implants are also gaining popularity. Most implants are joined without cement; the prosthesis is given a porous texture into which bone grows. This has been shown to reduce the need for revision. The ... [ Read More ]
