Arthroscopy was performed in the past. Arthroscopic knee surgery is one of the most common orthopaedic procedures, performed approximately 2 million times worldwide each year. The procedures are more commonly performed to treat meniscus injury and to perform anterior cruciate ligament reconstruction. While knee arthroscopy is commonly used for partial meniscectomy (trimming a torn meniscus) on middle aged to older adults with knee pain, the claimed positive results seem to lack scientific evidence. During an average knee arthroscopy, a small fiberoptic camera (the arthroscope) is inserted into the joint through a small incision, about 4 mm (1/8 inch) long. More incisions
Arthroscopy shown "high scores in terms of realism" and the ability to differentiate between "varying levels of arthroscopic experience". Reference material, such as the application developed by Touch Surgery, also contains visualization of minimally invasive techniques. Arthroscopy is considered a low risk procedure with a very low rates of serious complications. Commonly, irrigation fluid may leak (extravasates) into the surrounding soft tissue, causing edema which is generally a temporary phenomenon, taking anywhere from 7–15 days to completely settle. Rarely, this fluid may be the cause of a serious complication, compartment syndrome. However, Postarthroscopic glenohumeral chondrolysis (PAGCL) is a rare complication of
