Arthroscopy of the ankle and subtalar joint.

Arthroscopy has become a useful diagnostic and therapeutic tool in foot and ankle surgery. There are a reasonable number of indications for its use in the ankle and a limited number for the subtalar joint. Procedures previously performed as open surgeries typically necessitate a lengthy recovery and were met with higher complication rates. Many of these procedures can now be performed through small incisions with the assistance of arthroscopy. This article reviews the pathologies amenable to arthroscopy as well as describes the indicated procedures and technical aspects of each.
