Lower complication rate seen with endoscopic vs open excision of os trigonum

Although results from this study demonstrated both open and endoscopic excision of the os trigonum for athletes with posterior ankle impingement led to good function and pain outcomes, endoscopic treatment had a lower complication rate and a shorter time to return to full activities.
Researchers performed a randomized controlled trial of 52 athletes with posterior ankle impingement syndrome. Overall, 26 athletes underwent open excision of the os trigonum and 26 athletes underwent endoscopic incision. Postoperative complications, time to return to training or work, and time to return to sports were the primary outcomes. Preoperatively and at 6 months and 5 years postoperatively, the American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score was used to assess functional outcomes and VAS-foot and ankle scale was used to assess pain.
Investigators found athletes who underwent an endoscopic procedure compared with patients who underwent an open procedure had a significant improvement in the AOFAS hindfoot score. However, there was no difference between the two treatment groups with regard to the VAS- foot and ankle score. Time to return to previous sports in patients who underwent an open procedure and in patients who underwent an endoscopic procedure was 11.54 weeks and 7.12 weeks, respectively. According to researchers, patients in the open procedure group had a 23% complication rate, whereas those in the endoscopic procedure group had a 3.8% complication rate. – by Monica Jaramillo
