Posterior ankle impingement: retrospective study of the arthroscopic treatment

Abstract

Objective: Posterior impingement ankle syndrome (PIAS) refers to a group of pathologic entities that result from repetitive or acute forced plantar flexion. It is described in classic ballet dancers, and also in individuals who are active in sports, including soccer, basketball, running, and volleyball, as well as in those who participate in non-sport-related activities. The goal of this study was to evaluate, retrospectively, the results of the arthroscopic treatment for PIAS. Methods: A retrospective evaluation of medical record of 13 patients, being one case bilateral (14 ankles) who were submitted to arthroscopic treatment for PIAS, between 2005 and 2009. An evaluation of the radiographies, magnetic resonance imaging, AOFAS score and the satisfaction level of the patients was made. Results: The average AOFAS pre-operative score for the 14 cases was 65.1 points (58-73) and the AOFAS postoperative score was 89.4 points. This difference was considered statistically significative (pConclusion: The arthroscopic treatment for PIAS showed effectiveness, providing clinical improving and satisfaction for the patients.
