Ankle arthroscopy provides the surgeon with a minimally invasive treatment option for a wide variety of indications such as impingement, osteochondral defects, loose bodies, ossicles, synovitis, adhesions, and instability. Posterior ankle pathology can be treated using endoscopic hindfoot portals. These posteromedial and lateral hindfoot portals provide excellent access to the posterior aspect of the ankle and subtalar joint. Also extra-articular structures in the hindfoot, for instance recurrent peroneal tendon dislocation, can be treated by creating an additional portal. The endoscopic hindfoot portals are safe and reliable, both anatomically and clinically. It compares favorably to open surgery with regard to less morbidity and a quicker recovery.
