Curative effects of suture anchor tenodesis in repairing acute closed distal achilles tendon injuries / 天津医药

ABSTRACT

Objective To evaluate the effectiveness of the suture anchor in the treatment of acute closed distal achilles tendon rupture. Methods A retrospective review of clinical data in 25 patients with acute achilles tendon rupture was performed in the department of orthopedic trauma of Tianjin Hospital between October 2012 to January 2014. The operation was performed by standard approach, with the suture anchors to reconstruct the achilles tendon insertion, and the Krachow technique was used to suture the achilles tendon. All patients were followed up for 19~35 months. The situation of the wound healing, heel pain, and achilles tendon re-rupture were observed and analyzed. According to the passive range of motion of the bilateral ankle joint, the achilles tendon total rupture score (ATRS), the American orthopaedic foot and ankle society (AOFAS) score and functional recovery were assessed one year after operation. Results The operation was successfully completed in this group. The operation time was 25-35 min, the average time was (30.4 ± 4.8) min. No major vascular and nerve injury occurred in the operation. All patients were followed up. The wound healed well. No infection and skin necrosis, no heel pain and achilles tendon re-rupture were found during follow-up. There was no significant difference in mean passive plantar flexion between injured ankles and uninjured ankles one year after operation (44.36° ± 3.33° vs. 46.40°±4.53°, P>0.05). But mean passive dorsiflexion was lower in injured ankles than that of uninjured ankles (16.88°± 4.10° vs. 20.12°±3.21°,P<0.05). The mean ATRS score was 88.7±6.1 (range 79-97), and the mean AOFAS score was 92.4± 5.6 (range 76-100) at first postoperative year. According to the AOFAS scale, the results were excellent in 20 cases and good in 5 cases. Conclusion It was successful to repair the acute closed distal achilles tendon injuries with the suture anchors.
