Endoscopic calcaneoplasty for the treatment of Haglund’s deformity provides better clinical functional outcomes, lower complication rate, and shorter recovery time compared to open procedures: a systematic review

Purpose: The aim of this research is to report the clinical outcome following surgical correction of Haglund’s deformity summarising different surgical strategies and comparing clinical outcomes, failures, complications and return to activities of patients underwent open and endoscopic techniques. Methods: A systematic search of the literature was conducted using eight different databases. Thirty-five studies were included in the systematic review. A total of 1260 ankles of 1147 patients were grouped in accordance with the surgical approach (open, endoscopic, or percutaneous). Results: The overall mean age was 44.8 ± 8.2 (range 14.9–82) years with a mean follow-up of 30.9 ± 17.1 (range 3–132) months. Analysis of clinical outcomes of open and endoscopic techniques demonstrated significant differences of AOFAS (87.1 ± 5.9 versus 90.7 ± 4.2 points; P < 0.001), complications (15.5% versus 4.1%; P < 0.001), failures (6.0% versus 1.2%; P < 0.001), time to return to daily activities (17.2 ± 9.3 versus 6.3 ± 1.0 weeks; P < 0.001) and time to return to sport (20.7 ± 3.3 versus 11.9 ± 0.3 weeks; P < 0.001) in the studies that reported these specific outcome measures. Conclusion: Surgical correction of Haglund’s deformity provides overall good clinical results and high subjective satisfaction. Endoscopic procedures demonstrated better final AOFAS, a lower rate of complications and failures, and shorter recovery time when compared to open techniques. Level of evidence: Level IV.
