Which term describes the procedure of examining a knee joint using small incisions and an endoscope?

• A. Arthroscopy
• B. Arthroplasty
• C. Osteotomy
• D. Synovectomy

Answer: (A)

Arthroscopy is the procedure of examining a knee joint through small incisions using an endoscope. In this minimally invasive approach, a thin device called an arthroscope, which contains a camera and light, is inserted into the joint via tiny portals. The camera feeds images to a monitor, allowing the clinician to visualize the interior of the knee and, if needed, treat issues such as tears in the meniscus or damage to ligaments with specialized instruments inserted through additional small channels.

This term describes a visual diagnostic and potentially therapeutic approach inside the joint. Other terms refer to different procedures: arthroplasty is the joint replacement operation, osteotomy involves cutting and realigning bone, and synovectomy is the removal of the joint's synovial lining.
