Arthroplast means what?

• A. Surgical replacement of a joint.
• B. Arthritis of the hip.
• C. Inflammation of a joint.
• D. Wasting away due to lack of use.

Answer: (A)

Arthroplast means a surgical reconstruction or replacement of a joint. It comes from arthro- meaning joint and -plasty meaning forming or molding, indicating restoration rather than mere inflammation or degeneration. In practice, an arthroplasty replaces the worn or damaged joint surface with a prosthesis to restore movement and relieve pain, as in hip or knee arthroplasty. This is different from arthritis, which is inflammation of a joint, or from wasting away due to disuse, which describes atrophy rather than a surgical procedure. Other joint procedures, like arthrodesis, fuse a joint and are not the same as an arthroplasty.
