The arthroscopic management of frozen ankle.
OBJECTIVE
The purpose of this study was to evaluate a combined anterior and posterior arthroscopic approach in the treatment of frozen ankle.


METHODS
Retrospective case series.


METHODS
Five patients with post-traumatic frozen ankle were evaluated.


RESULTS
After an average follow-up of 32.6 months (range, 24 to 42 months), the average American Orthopaedic Foot and Ankle Society hindfoot-ankle score was improved from 63.8 point (range, 55-74) to 88.6 point (range, 81-100). The average ankle dorsiflexion improved from 1 degrees (range, 0 degrees to 5 degrees) to 19 degrees (range, 15 degrees to 25 degrees). The average ankle plantarflexion improved from 16 degrees (range 10 degrees to 20 degrees) to 39 degrees (range, 30 degrees to 45 degrees).


CONCLUSIONS
Combined posterior ankle endoscopy and anterior ankle arthroscopy is effective in the treatment of post-traumatic frozen ankle.
