Hip replacement is a surgical procedure in which the hip joint is replacing by a prosthetic implant, that is, a hip prosthesis. Hip replacement surgery can performed as a total replacement or a hemi (half) replacement. Such joint replacement orthopedic surgery is generally conducting to relieve arthritis pain or in some hip fractures. A total hip replacement (total hip arthroplasty or THA); consists of replacing both the acetabulum and the femoral head while hemiarthroplasty; generally only replaces the femoral head.
Total hip replacement is most commonly using to treat joint failure caused by osteoarthritis. Other indications include rheumatoid arthritis, avascular necrosis, traumatic arthritis, protrusion acetabuli, certain hip fractures, benign and malignant bone tumors, arthritis with Paget’s disease, ankylosing spondylitis and juvenile rheumatoid arthritis. The aims of the procedure are pain relief and improvement in hip function. Hip replacement is usually considering only after other therapies; such as physical therapy and pain medications, have recently failed.
The total hip replacements
Hip replacement is currently one of the most common orthopedic operations; though patient satisfaction short- and long-term varies widely. Approximately 58% of total hip replacements are estimated to last 25 years. The average cost of a total hip replacement in 2012 was $40,364 in the United States and about $7,700 to $12,000 in most European countries.
A new Johns Hopkins Medicine study looking at medical records of more than 43,000 U.S. adults; with hip-joint damaging osteoarthritis suggests that those who cannot perform daily activities independently before total hip replacement; surgery are more likely to have poorer outcomes after surgery. Overall, those less able to care for themselves appeared to two to three times more likely to have surgical complications and to spend; time in a nursing or rehab facility before going home and to have a 19% longer length of hospital stay.
The postoperative outcomes
The researchers to conclude that a pre-operative assessment of the ability to perform daily activities such as taking showers; eating, getting dressed and going to the bathroom can used as a simple tool to help predict postoperative outcomes. This will further help determine if other interventions such as physical therapy are need beforehand to better prepare the patient for surgery and increase the likelihood of a successful result.
With an aging society, we see an increased number of people who needs or are referred for hip replacement surgeries. However, without a better understanding of factors that influence outcomes after surgery, they may not make the best treatment plans for our patients, and our study offers a simple tool to help inform treatment decisions. Researchers say future studies are needs to explore more precise and standardized ways to measure daily self-care abilities.
