Abstract
Aims: Posterior ankle pain is a characteristic of the posterior ankle impingement syndrome (PAIS). Currently, this condition is commonly treated arthroscopically following the technique published in 2000 by van Dijk et al. We aimed to investigate our outcomes in treating PAIS using this technique and to compare them to those published in the available literature. Methods: From January 1, 2011 until January 1, 2020, 47 patients were operated on for PAIS at the Department of Orthopedic Surgery, Zagreb University Hospital Center in Zagreb. The available medical records were systematically searched for demographic data, information about sports activities and ankle trauma, radiological studies, as well as previous surgical procedures on the ankle. Operation notes were thoroughly searched for the procedure details, type of anesthesia, and application of a tourniquet. Clinic records were scoured for complications noted or notes on ankle reoperations. The ankle function was assessed before the procedure and on the last check-up using the American Orthopedic Foot & Ankle Society (AOFAS) score. Patient satisfaction was evaluated using the questionnaire published by Abdelatif. Results: This study included 42 patients (25 male), mean age at the time of the procedure 27.2 (range 15 to 63) years. The median follow-up period was 80 (range 24 to 127) months. A history of ankle trauma was confi rmed in 27 (64.3%) cases. In 34 (80.7%) cases, PAIS was the consequence of bony impingement. Tourniquet was used in 31 (73.8%) cases. There were no complications noted during the procedure, with only one postoperative complication (2.4%) presenting as transient lateral foot sensitivity palsy that spontaneously resolved in 4 weeks. The mean preoperative AOFAS score was 71.9 (range 60 to 86), while the mean AOFAS score on the last follow-up was 95.7 (range 78 to 100). Based on Abdelatif questionnaire, 39 (92.8%) patients were very satisfi ed with the procedure. Discussion: The number of comparable studies in the literature is small. Literature review yielded only fi ve studies which had a follow-up period of minimally 60 months. Moreover, only two of those included more than 30 patients. In these two studies, similar to ours, assessment of the functional state of the ankle showed improvement. In addition, the procedure appears to be highly successful in allowing the patients to return to sports activities. Furthermore, thecomplication rate in our study (2.4%) was comparable or lower than in other studies. Conclusion: Our research confi rmed that arthroscopic treatment for PAIS using the van Dijk et al. technique was safe and effi cient even after a longer follow-up period, and it also consistently allowed return to sports activities.
