Final answer:
The client underwent a right knee arthroplasty, which is a joint replacement surgery designed to alleviate chronic pain and enhance mobility. Post-operative X-rays confirm the procedure was for the right knee.
Therefore, option b is correct.
Step-by-step explanation:
The surgical procedure the client underwent is a right knee arthroplasty. Arthroplasty, also known as joint replacement surgery, is one of the most common treatments for severe osteoarthritis (OA) in the knee or hip. This highly invasive surgical process is only considered after other treatments have been tried. Knee arthroplasty involves replacing the articular surfaces of the knee joint bones with a prosthesis, which are artificial components. These surgical components are designed to alleviate chronic pain and enhance mobility. Given the provided information, which includes post-operative X-rays showing a right knee joint replacement, we can deduce that the correct answer is option b, right knee arthroplasty.
