Which of the following terms refers to the surgical repair of a joint?

Arthroplasty is the term that specifically refers to the surgical repair or reconstruction of a joint. This procedure is often performed to improve the function and mobility of a joint that may have been damaged due to conditions such as arthritis, injury, or other diseases. During arthroplasty, joint surfaces may be replaced or reshaped, and it often involves the use of prosthetic devices in cases of severe joint degeneration.

The other terms listed have distinct meanings related to joints but do not describe the surgical repair process. Arthroscopy involves the use of a small camera to visualize the inside of a joint for diagnostic or therapeutic purposes, rather than directly repairing it. Arthrectomy refers to the surgical removal of a joint or a portion of it. Arthrography is a diagnostic imaging technique that involves the injection of a contrast dye into a joint space to visualize it on X-rays or MRI scans, providing information about the joint's condition rather than performing a repair.
