Hip replacement surgery, also known as hip arthroplasty, is a common and highly effective procedure designed to alleviate pain and improve function in individuals suffering from severe hip joint damage. This damage often results from conditions such as osteoarthritis, rheumatoid arthritis, or traumatic injury. During the surgery, the damaged hip joint is replaced with a prosthetic implant made of metal, ceramic, or high-density plastic. The procedure can be performed as a total hip replacement, where both the acetabulum (hip socket) and the femoral head (thighbone) are replaced, or as a partial hip replacement, where only the femoral head is replaced. Patients typically undergo this surgery after non-surgical treatments, like physical therapy and medications, fail to provide sufficient relief. Hip replacement surgery can significantly reduce pain, enhance mobility, and improve the overall quality of life. Recovery involves a combination of hospital stay, physical rehabilitation, and a gradual return to daily activities. Most patients can resume normal activities within a few months post-surgery, although full recovery can take up to a year. Advances in surgical techniques and implant materials have increased the success rates and longevity of hip replacements, making it a reliable solution for many people facing debilitating hip joint conditions.
