At the final follow-up, AT elongation was assessed using ATRA. Plantarflexion strength (peak torques and angle-specific torques) was measured using an isokinetic dynamometer. All variables were obtained from the operated and unoperated contralateral ankles of the patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The mean ATRA was greater in the operated ankles (mean, 57 degrees; range, 39-71 degrees) compared with the unoperated ones (mean, 52 degrees; range, 36-66 degrees; P = .009). Except the plantarflexion torque at 20 degrees of plantarflexion ( P = .246), all the other angle-specific torques were lower in the operated ankles ( P &lt; .05). Peak flexion torque at 30 degrees\/s was lower in the operated ankle ( P = .002). A negative correlation was found between operated\/unoperated (O\/N) ATRA and O\/N plantarflexion torque ratios at 0 degrees ( r = \u22120.404; P = .01), 10 degrees ( r = \u22120.399; P= .011), and 20 degrees ( r = \u22120.387;
