Which procedure uses an endoscope inserted into a joint through a small incision?

• A. Endoscopy
• B. Arthrodesis
• C. Arthroplasty
• D. Arthroscopy

Answer: (D)

Arthroscopy is the procedure that uses an arthroscope inserted into a joint through a small incision. The arthroscope is a tiny camera that lets the surgeon view the inside of the joint and perform treatments with small instruments through additional little portals, all through minimally invasive access. This is distinct from a general endoscopy, which refers to examining hollow organs or cavities rather than a joint. Arthrodesis fuses the joint, and arthroplasty replaces it, neither of which involves inserting an endoscope into the joint.
