title: Arthroscopic excision of the os trigonum: a new technique with preliminary clinical results.
abstract: Open excision of a painful os trigonum can be associated with prolonged recovery. An arthroscopic technique has been developed to decrease scarring, diminish surgical morbidity, and promote a faster recovery. Eleven patients were retrospectively evaluated after removal of the os trigonum after a mean follow-up of 35 months. Small joint arthroscopy equipment was utilized in a supine position with a distraction device. Average patient scores improved on the AOFAS Ankle/Hindfoot Scale from 45 to 86 points. All patients went home the same day, and no complications occurred during the procedure. All patients reached maximum recovery level within the first 3 months after surgery. Arthroscopic excision of a painful os trigonum yields good results with minimal surgical morbidity and shorter recovery time.
