Hip replacement surgery involves surgically removing the damaged hip joint and replacing it with an artificial joint made of metal and plastic components. It is usually an option after other treatments have failed to provide relief from pain caused by conditions like osteoarthritis or rheumatoid arthritis. While age is less of a factor now, overall health and ability to recover are important considerations for whether someone is a good candidate for replacement surgery. The procedure takes 1-2 hours and involves removing diseased bone and cartilage and replacing it with artificial femoral head and acetabulum components. Limited movement is allowed after surgery, and exercises like clam shells help strengthen muscles while avoiding twisting or back strain during recovery.
