Open curettage with bone graft has been the traditionally suggested surgical treatment for the symptomatic simple (or unicameral as they used to be called) calcaneal bone cyst. Less invasive endoscopically assisted treatment with curettage and bone grafting with allograft have recently provided less postoperative morbidity. The aim of the present study is to present our experience with this method in young soccer athletes. Between April 2014 and May 2016 three consecutive young soccer players with symptomatic calcaneal bone cysts underwent endoscopic curettage, and percutaneous injection of demineralized bone matrix allograft. The mean age was 17.3 (16, 17 and 19 years old), and the mean follow-up was 32.1 (range 24-47) months. Both radiographic and functional follow-up, using the AOFAS score, showed good to excellent results. All lesions were radiographically healed. Preoperative AOFAS score (max. 100 pts) was 78.6 ± 4.7, improving to 98.0 ± 4.1. The patients returned to their initial level of sports activities within 18.3 (range 17-19) weeks after surgery. Evidence suggests an earlier return to sports using bone substitutes. However, the present study showed that endoscopic curettage and percutaneous injection of bone allograft is also an excellent treatment option for young athletes with a symptomatic calcaneal bone cyst. LEVEL OF CLINICAL EVIDENCE: 4.
