What procedure involves the replacement of a joint?

Arthroplasty is the procedure specifically designed for the replacement of a joint. This surgical intervention involves removing a damaged joint and replacing it with either a prosthetic device or reconstructing the joint surface to restore function and alleviate pain. It is commonly performed on weight-bearing joints such as the hip or knee, where joint degeneration from arthritis or injury significantly hampers movement and quality of life.

In contrast, arthroscopy refers to a minimally invasive surgical technique used to visualize, diagnose, and treat joint problems, but it does not inherently involve replacing the joint itself. Arthrodesis, often referred to as joint fusion, involves the surgical fusion of a joint to eliminate motion and relieve pain, rather than replacing it. Osteotomy involves cutting and repositioning bone, often to correct deformities or joint alignment issues but does not entail joint replacement. Therefore, arthroplasty is the correct term associated with joint replacement surgery.
