What is the definition of arthrectomy?

Arthrectomy refers specifically to a surgical procedure that involves the removal of all or part of a joint. This procedure may be indicated for various reasons, such as severe joint disease, damage, or infection that cannot be managed by other means. By removing the affected joint tissue, the procedure aims to reduce pain and improve function in certain cases. Understanding this term is essential, particularly in the context of orthopedic procedures that deal with joint health and management.

In contrast, the other options represent different surgical concepts. The first choice relates to tenotomy, which specifically refers to an incision made into a tendon but is not related to joints. The second choice involves tissue transplantation, known as grafting, typically focusing on tissues from identical twins, known as isografts, which does not pertain to joint removal. Finally, the fourth option describes a xenograft, referring to a graft obtained from a different species, which again is unrelated to the concept of arthrectomy. Thus, the focus on joint removal solidifies the designation of arthrectomy as the correct definition.
