Endoscopy of the Posterior Aspect of the Ankle: Double Posteromedial Portals.

Posterior and anterior arthroscopy of the ankle and hindfoot may have to be undertaken at the same surgical sitting. Standard arthroscopic practice does not allow to approach both compartments without changing the position of the patient. In the supine position, most intra-articular structures of posterior portion of the ankle joint can be accessed from anterior portals with judicious traction, but visualization of posterior extra-articular compartment and hindfoot are not possible.
