Return to dance after excision of os trigonum via an open posterolateral approach in classical ballet dancers

Abstract

We investigated the recovery status of 24 legs of 20 classical ballet dancers who underwent open procedures for os trigonum between 2016 and 2022. The average amount of time during which participants did only center practice 5.5 weeks (range, 3-10), and the average amount of time full return was 10 weeks (range4-24), and 22 out of 24 legs (92%) recovered fully within 12 weeks. Seventeen patients returned to dance without any complaint, 3 had residual symptoms that did not affect their dancing, and 100% returned to dancing. A comparison the literature found that, the recovery period was almost identical to that achieved with endoscopic resection.
