Methods
A retrospective review from the senior author's (J.M.C.) database was performed evaluating a consecutive series of patients presenting with a symptomatic os trigonum starting in April 2012. Inclusion criteria consisted of patients with a symptomatic os trigonum verified by examination, imaging, and diagnostic injection who failed nonoperative management. Exclusion criteria included the absence of an os trigonum, the presence of Outerbridge grade 3 or 4 osteoarthritic changes in the ankle, and
Results
Twenty-four patients with a symptomatic os trigonum were included in this study. There were 13 male and 11 female patients. The right ankle was involved in 9 and the left in 15. The average age was 36.7 ± 17 years (range, 15 to 82 years). There were 4 patients in whom symptom onset was associated with injury or trauma, and 20 described a gradual onset. Of the 24 procedures, 5 were isolated excisions of the os trigonum and 19 were associated with other procedures. These included tenolysis of the
Discussion
Arthroscopic excision of a symptomatic os trigonum in the prone position without traction, viewing first through the posteromedial portal and then through the posterolateral portal and using a high-speed burr in the posterolateral portal and then the medial portal, is both safe and effective. This technique provides comparable outcomes to other approaches, as well as a low complication rate, and resulted in significantly improved AOFAS scores.
Arthroscopic excision of a symptomatic os trigonum
Conclusions
Arthroscopic excision in the prone position without traction of a symptomatic os trigonum viewing initially through the posteromedial portal with a high-speed burr in the posterolateral portal resulted in significantly improved AOFAS scores with a single transient neurapraxia in 24 patients. Patients returned to their normal daily activities without limitations at an average of 1.5 months.
