Knee Arthroscopy

Knee arthroscopy has in many cases replaced the classic arthrotomy that was performed in the past. Today knee arthroscopy is commonly performed for treating meniscus injury, reconstruction of the anterior cruciate ligament and for cartilage microfracturing. Arthroscopy can also be performed just for diagnosing and checking of the knee; however, the latter use has been mainly replaced by magnetic resonance imaging.

During an average knee arthroscopy, a small fiberoptic camera (the endoscope) is inserted into the joint through a small incision, about 4 mm (1/8 inch) long. A special fluid is used to visualize the joint parts. More incisions might be performed in order to check other parts of the knee. Then other miniature instruments are used and the surgery is performed.

Recovery after a knee arthroscopy is significantly faster as compared to arthrotomy. Most patients can return home and walk using crutches the same or the next day after the surgery. Recovery time depends on the reason that surgery was needed and the patient's physical condition. Usually a patient can fully load his leg within a couple of days and after a few weeks the joint function can fully recover. It is not uncommon for athletes who have an above average physical condition to return to normal athletic activities within a few weeks.
