Which term refers to a surgical joint replacement of the hip?

• A. Total Hip Replacement
• B. Total Knee Replacement
• C. Arthroplasty
• D. Osteoarthritis

Answer: (A)

When a joint is surgically replaced, the procedure for the hip is called a total hip replacement. This term specifies replacing the hip joint itself, typically with a prosthetic ball and socket, and is also known as a total hip arthroplasty.

Total knee replacement refers to replacing the knee joint, not the hip. Arthroplasty is a broad term for joint replacement in general, applicable to any joint, not the hip specifically. Osteoarthritis is a disease that damages joints and can lead to the need for replacement, but it is not a procedure.

So the term that describes a surgical hip joint replacement is total hip replacement.
