Final answer:
Arthroscopy is the visual examination of the interior of a joint, where an arthroscope is used for visualization and potential repair, allowing quicker recovery times than traditional open surgery.
Step-by-step explanation:
An arthroscopy is a visual inspection of a joint's inside. This procedure involves a small incision and the insertion of an arthroscope, a pencil-thin instrument that enables a surgeon to view and sometimes repair joint issues. It is an advantageous technique as it generally allows for quicker recovery times compared to open surgery due to the smaller incisions made during the procedure.
