Arthroscopy is a term used to describe an examination of a joint space by inserting a scope surgically into the joint space. It is possible to do the procedure in every joint in the body. Commonly, arthroscopy is done on the knee, hip, shoulder, elbow, wrist, ankle, and foot.
Arthroscopy of the knee is done both for diagnostic and therapeutic purposes. Usually two small incisions are made at the knee joint. One incision is used as the site where the arthroscope is inserted for viewing. The second site is used to insert instruments to repair any damaged tissue.
Common arthroscopic repairs are done for loose cartilage, torn meniscus, ligament repair, and treating infection. The advantage over traditional surgery is the small incisions and the rapid healing time. There is less scaring and led potential for infection.
