Arthroscopic knee surgery is effective due to technological advances, such as high-resolution cameras and high-definition monitors, states the American Academy of Orthopaedic Surgeons. As of 2015, surgeons worldwide annually perform over 4 million procedures in which the surgeon views the surgical area using a miniature camera.
The surgeon inserts the arthroscope, which is a pencil-sized camera, into the patient's knee joint. The arthroscope transmits the picture to a television screen that allows the surgeon to observe minute details in the area, notes the American Academy of Orthopaedic Surgeons. Using small surgical equipment, the surgeon removes or repairs damaged knee cartilage.
The surgical success rate is approximately 90 percent in patients who undergo arthroscopic repair of the meniscus, which is a common procedure, states University of Washington Orthopaedic and Sports Medicine.
