| Popis: | Category: Arthroscopy Introduction/Purpose: The Posterior Ankle Impingement Syndrome (PAIS) can be treated by the endoscopic technique with posterior portals and patient in prone position. There is discussion whether this would be the best method, given the possible difficulty in learning and applying this technique, risks of complications and prolonged time of surgery. We conducted this retrospective study to assess the time spent to perform the posterior endoscopy along the learning curve and the relationship of the duration of the procedure to the presence of complications. Methods: We evaluated 39 patients undergoing endoscopic treatment through posterior ankle portals technique and prone position, operated by a single surgeon between 2005 and 2014. We divided the patients into four groups of ten subjects according to the chronological sequence of the surgeries. We used the Jonckheere-Terpstra test to compare the surgery time between the four analyzed groups. We used the Mann-Whitney test to compare operative time and the occurrence of complications, and the relationship between surgical procedure time and presence of intraoperative fibrosis. We used the Wilcoxon signed-rank test to compare preoperative and postoperative AOFAS Ankle-Hindfoot Score. For all statistical analysis, p-values |
