Postoperatively, a below-knee splint was applied for 2 weeks in 20 degrees of plantar flexion and then active range of motion exercise was started. Partial weightbearing exercise was allowed at 4 weeks according to patient tolerance, and full weightbearing without crutches was allowed at 8 weeks. The American Orthopaedic Foot &amp; Ankle Society (AOFAS) ankle-hindfoot scale score and the Achilles tendon rupture score (ATRS) were used to evaluate clinical outcomes preoperatively and at the final follow-up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Ten patients (6 men, 4 women) were included in the analysis. Mean AOFAS ankle-hindfoot scale score increased significantly from 64.2 \u00b1 5.6 points preoperatively to 95.0 \u00b1 5.3 points at the final follow-up ( P &lt; .001). The mean ATRS also increased significantly from 29.8 \u00b1 4.4 points to 86.2 \u00b1 7.7 points, respectively ( P &lt; .001). Mean time between surgery and ability to perform 20 continuous double-leg heel raises of the operated foot was 13.5 \u00b1 3.4 (range 10-18) weeks. One patient complained of postoperative hypoesthesia in the foot, which had spontaneously resolved by 3 months after surgery.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
