Arthroscopy (Scope)
Arthroscopy is an internal examination of the knee joint to determine damage to the bone or cartilage. The arthroscopy procedure provides the surgeon with a close-up and enlarged view during examination and repair (or treatment) of the knee joint.
The Arthroscopic Procedure |
|
 |
The arthroscope is an instrument attached to a light source and video camera. The arthroscope allows internal images of the knee joint to be magnified and viewed by the surgeon on a television screen (located inside the operating room). Click to view sample of what the physicians see on the television screen when examining a torn meniscus with a probing hook. |
|
The scope begins as portals (small incisions) are made to accommodate the arthroscope and other surgical instruments. |
|
 |
Other surgical instruments (such as a blunt probing hook, a shaver and cutting tools) are used for the examination and repair(s) of joint damage. Sterile fluid is used to fill and expand the knee joint for easier access and viewing.
|
The arthroscope is inserted into one portal and the probing hook, which acts as a "finger", is inserted into another. A thorough examination of the joint is done with the arthroscope and probing hook. Following the exam, the appropriate surgical instrument is inserted through a portal to repair, treat, and/or remove the damaged portion(s) of the joint. |
 |
The fluid is drained, the arthroscope is removed, and dressings are applied. |
