Arthroscope is one of the very important tools used by orthopedic surgeons to diagnose and operate inside joints. With this development in instrumentation, more ankle joint disorders were treated. Arthroscopy of the subtalar joint for diagnosing and treating subtalar joint abnormalities has also become an accepted method. Arthroscope is a pen-shaped device with a video camera attached to its tip that transmit actual picture of a joint and can be projected in a monitor screen. Through the use of arthroscope visualization of the entire joint can be better, including the lateral and medical aspect gutters and the posterior of the joint Moreover, arthroscopy hasten patient’s healing recovery, less morbidity and reduces scarring. While open surgery often requires an inpatient stay in the hospital, Arthroscopy gives the patient the privilege of not staying overnight in the hospital. Many studies have been performed to stress ligaments or identify areas of soft-tissue or bony impingement.

Traditional measures and diagnosis imaging studies for chronic ankle pain and swelling has not been very satisfactory. When the cause of symptoms remains unclear, arthroscopic examination guarantees absolute diagnosis. MRI and other imaging studies neither can show nor demonstrate symptoms that causes Chondromalacia or synovium inflammation. Ankle arthroscopy can also help aide diagnostic exploration to patients with episodes of locking, stiffness, or instability for which causes cannot be found. Cartilage flaps, arthrofiobrosis or loose bodies, arthroscopically may be contributing to such. Ankle fractures fixation assisted by arthroscopy has been more accurate in realigning of joint surfaces and identification of chondral lesions that would otherwise be missed. The use of arthroscope however in the treatment of most routine ankle fractures probably is not indicated. Thus, joint surgery has greatly improved since the arthroscopy tool came out.
