Abstract:To explore the clinical effect of arthroscopic minimally invasive calcanealplasty in treatment of Haglund syndrome. Methods 15 patients with Haglund syndrome treated by arthroscopic minimally invasive calcanealplasty from June 2015 to July 2017, the American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score and pain visual analogue scale (VAS) score were used to evaluate clinical outcomes preoperative, at 3 months postoperative and at 12 months postoperative, the data was analyzed by SPSS software. Results All these 15 patients were followed up for 12 ~ 24 months, with an average of 17 months. Compared with preoperative, AOFAS hindfoot score at 12 months postoperative was significantly higher than preoperative and at 3 months postoperative, VAS score at 12 months postoperative was significantly lower than preoperative and at 3 months postoperative. Conclusion Arthroscopic minimally invasive calcanealplasty for the treatment of Haglund syndrome has less trauma and quick recovery, and the clinical effect was significant.
