Ankle arthroscopy is an endoscopic method which allows observation of the joint and surgical intraarticular intervention without arthrotomy and/or malleolar osteotomy. Ankle arthroscopy, which was originally defined on cadavers, was first developed in 1980s. Currently, it is the third major method which has been widely used. Ankle arthroscopy (anterior and posterior) and hind-foot endoscopy allow diagnosis and treatment of pathologies involving whole ankle and hind-foot, subtalar joint and the adhesion site of the Achilles tendon. The complication rate of this method is relatively higher (9-17%) than other joints and is mostly associated with portals. Most of them (48%) are nerve injuries. Therefore, the initial step should be learning portal anatomy. Entrapment syndromes (soft tissue and bone) and osteochondral lesions of the Talus are clinical conditions with successful outcomes. It is also useful in the management of several intraarticular pathologies, degenerative arthritis, septic arthritis, instabilities, pathologies related to peroneal tendons and flexor hallusis longus tendon, Os Trigonum syndrome, Hauglund deformities, and adhesion site of the Achilles tendon.
