What type of procedure involves replacing damaged or diseased joints?

Arthroplasty
Arthroscopy
Osteotomy
Chondroplasty

The correct answer is: Arthroplasty

Arthroplasty is a surgical procedure specifically aimed at replacing damaged or diseased joints. This procedure is commonly performed on joints that are affected by conditions such as arthritis or injury, where the joint surface is severely compromised, leading to pain and decreased mobility. In arthroplasty, the damaged joint is removed and replaced with an artificial joint, often made from metal, plastic, or ceramic materials, designed to restore function and alleviate pain. Other procedures, while related to joint issues, serve different purposes. Arthroscopy involves the use of a small camera and instruments to visualize and treat problems inside a joint, but it does not replace the joint itself. Osteotomy is a procedure that involves cutting and repositioning bone, usually to realign a joint, rather than replacing it. Chondroplasty focuses on repairing or smoothing the cartilage surface of a joint rather than replacing it. Thus, arthroplasty is unique in its direct approach to joint replacement, making it the correct answer in the context of the question.
