Arthroscopy

Reviewed by Mr Dai Rees, consultant orthopaedic surgeon

What is an arthroscopy?

An arthroscopy is a type of test to see inside a joint. An arthroscope is a telescope that can be inserted into the joints, enabling the doctor to see directly inside the area.

What is arthroscopy used for?

Arthroscopy is often used for treatment of knee, ankle and shoulder joint injuries.

To discover the reasons for swellings, pains, unstable joints or why the patient cannot move as easily as they should.

The test might also show evidence of cartilage or ligament damage, loose bodies or signs of arthritis.

Arthroscopy can also be used for surgery such as trimming or repair of a cartilage or removing loose bodies.

What happens during an arthroscopy?

Arthroscopy can be performed under local or general anaesthesia.

Two small stab wounds are made on either side of the front of the knee. One is for the telescope, the other is either for an examining probe, or the instrument used to perform arthroscopic surgery.

In a patient under 60 years of age with no other medical problems, it is usually a day-case procedure. In most cases, no splints or crutches are required and driving and work can be resumed a few days later.
