Patient satisfaction, functional outcome, pain scores, and health\u2010related quality of life were measured by the use of a numeric rating scale, the Foot and Ankle Outcome Score, the Victorian Institute of Sport assessment for the Achilles tendon, the numeric rating scale for pain during running and during sports, and the EuroQol 5D (EQ\u20105D\u20103L) standardized questionnaire.

Thirty\u2010five (78%) patients were treated unilaterally and 10 (22%) patients were treated bilaterally. For the unilaterally treated patients, the median time to follow\u2010up was 67\u00a0months (interquartile range [IQR] 48\u201099\u00a0months), and for the bilaterally treated patients, it was 89.5\u00a0months (IQR 37.5\u2010161.75\u00a0months). The median satisfaction score for treatment results was 9 out of 10 (IQR 7\u201010) and 9.5 (IQR 7\u201010), respectively. The median Foot and Ankle Outcome Score subscales were scored 75 to 99 and 75 to 97, the median Victorian Institute of Sport assessment for the Achilles tendon scored 81 (IQR 47\u201090) and 97 (IQR 87\u2010100), and the median numeric rating scale pain scores during both running and sports were 1 (IQR 0\u20106.5) for the unilaterally treated patients and 0 (IQR 0\u20104.5) and 0 (IQR 0\u20101) for the bilaterally treated patients, respectively. The median EQ\u20105D were 0.81 (IQR 0.71\u20101) and 1 (IQR 0.64\u20101), respectively.
