b) Knee, shoulder, and ankle
c) Hip, knee, and shoulder
d) Wrist, ankle, and elbow

Answer 1

c) Hip, knee, and shoulder

The most common joint replacements in older adults are for the hip, knee, and shoulder, primarily to treat osteoarthritis and improve mobility.

Step-by-step explanation:

The three most common joint replacements performed on older adults are those of the hip, knee, and shoulder. Developments in prosthesis design have made these types of surgeries more effective for treating severe osteoarthritis (OA) and enhancing patient mobility. The hip and knee replacements are particularly common due to the high demand placed on these joints and their susceptibility to damage caused by wear, obesity, and high-impact activities. For patients undergoing hip arthroplasty, the procedure typically involves replacing the damaged parts of the hip joint with artificial components crafted from various materials like synthetic polymers and sometimes new materials like carbon fiber for increased durability.
