What does arthroscope mean?
An arthroscope is a thin, rigid optical instrument used by surgeons to look inside a joint. Fitted with a light source and, in modern versions, a miniature camera, it is inserted through a very small incision, allowing the physician to examine structures such as cartilage, ligaments, and the synovial lining without opening the joint fully. The device is central to arthroscopy, a form of minimally invasive surgery in which additional instruments are passed through separate small incisions to repair or remove damaged tissue. Arthroscopes are most commonly associated with the knee and shoulder, but they can also be used on the hip, wrist, ankle, elbow, and smaller joints of the hand and foot. The invention of the arthroscope transformed orthopaedic medicine: procedures that once required large, painful incisions and long hospital stays can now often be performed on an outpatient basis, with less pain, less scarring, and faster recovery for the patient.
nounA thin, rigid surgical instrument with a light and camera at its tip that is inserted into a joint through a small incision, allowing a surgeon to view the joint's interior directly during diagnosis or minimally invasive surgery.
- A slender endoscopic instrument inserted into a joint through a small incision to allow visual examination of the interior of the joint, typically equipped with a light source and camera.
"Using the arthroscope, the surgeon examined the torn meniscus without making a large incision."
"The surgeon threaded the arthroscope through a tiny incision to inspect the damaged cartilage in the patient's knee."
"Advances in fibre-optic technology have made the modern arthroscope small enough to visualize even the smallest joints of the hand."
The regular English plural applies. Because the word usually denotes a type of instrument rather than a countable object in everyday contexts, the singular is far more common than the plural.
"The operating theatre stocks several arthroscopes of varying diameters for different joints."
The arthroscope turned knee surgery from a weeks-long hospital stay into a day procedure — all thanks to a tube thinner than a pencil.

Etymology of arthroscope
The word "arthroscope" derives from Greek roots: "arthron," meaning "joint" (as seen in "arthritis" and "arthropod"), and the combining element "-scope," from "skopein," meaning "to look or examine." The term entered English in the early twentieth century alongside the development of the technique it names, arthroscopy. It shares its classical roots with many other medical terms built from "arthr-" (joint), such as "arthralgia" (joint pain) and "arthropathy" (joint disease).

How arthroscope is actually used
The word belongs primarily to medical and clinical register; laypeople more often encounter the derived term "arthroscopy," which refers to the procedure performed with the instrument. The plural "arthroscopes" is straightforward but rarely needed outside technical discussion.
