This study aims to describe our operative technique for Myerson type III CATR and its clinical outcomes. From May 2012 to April 2015, we treated seven patients (6 males, 1 female) with Myerson type III CATR using semitendinosus tendon and gracilis tendon autograft. The mean age was 47.3 years (range: 37每56). Patients were followed for a mean time of 31.3 months. All patients* defect size between Achilles ends after debridement was more than 5 cm and hence classified as Myerson type III. The clinical outcomes were evaluated by visual analog scale (VAS) for pain, American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot score, Achilles tendon total rupture score (ATRS), and the Short Form 36 (SF-36). All patients reported good postoperative clinical outcomes. The average AOFAS score increased from 54.29 points (range: 46每65 points) preoperatively to 97.57 points (range: 90每100 points) at last follow-up. The average ATRS increased from 51.43 points (range: 40每61 points) preoperatively to 92.71 points (range: 83每100 points) at last follow-up. And the average VAS for pain was 0 at the last follow-up. The mean value of SF-36 physical increased from 32.14 points (range: 25每35 points) to 90 points (range: 80每95 points). And the mean value of SF-36 mental was improved from 37.14 points (range: 32每40 points) to 90.86 points (range: 84每96 points).
