The Arthroscopic Management of Frozen Ankle

      Purpose: The purpose of this study was to evaluate a combined anterior and posterior arthroscopic approach in the treatment of frozen ankle. Type of Study: 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° (range, 0° to 5°) to 19° (range, 15° to 25°). The average ankle plantarflexion improved from 16° (range 10° to 20°) to 39° (range, 30° to 45°). Conclusions: Combined posterior ankle endoscopy and anterior ankle arthroscopy is effective in the treatment of post-traumatic frozen ankle. Level of Evidence: Level 4.
