Abstract:Abstract: [Objective] To compare the clinical effects of three percutaneous suture techniques in repairing acute closed achilles tendon rupture. [Methods] Retrospective analysis of 98 patients with acute closed achilles tendon rupture who underwent surgical treatment in our hospital from January 2016 to October 2021. According to the results of preoperative doctor-patient communication, 47 cases were treated with 3-hole loop method. 28 cases were treated with 3-hole Bunnell method; 23 cases were treated with 6-hole Bunnell method. Perioperative period, follow-up and ankle function data of the three groups were compared. [Results] There was no significant difference in operation time, blood loss, walking time and hospitalization time among the three groups (p>0.05). The total incision length of 3-hole method was significantly shorter than that of 6-hole method (P<0.05). The complete weight-bearing time of 3-hole loop group was earlier than that of 3-hole Bunnell group and 6-hole Bunnell group (P<0.05), but there was no significant difference between 3-hole Bunnell group and 6-hole Bunnell group. There was no difference in VAS score, AOFAS score and ATRS score between the three groups at 1 month after operation (P>0.05), but the VAS score, AOFAS score and ATRS score of 3-hole loop group at 6 months after operation were significantly better than those of 3-hole Bunnell group and 6-hole Bunnell group (P<0.05). At the last follow-up, there was no significant difference in VSA score, AOFAS score and ATRS score among the three groups (P>0.05), but VAS score decreased with time (P<0.05) and AOFAS score and ATRS increased with time (P<0.05). There was no significant difference in plantar flexion-extension ROM among the three groups at 1 month, 6 months and the last follow-up after operation (P>0.05), but the ROM of plantar flexion-extension in the three groups increased significantly with the prolongation of the follow-up time after operation (P<0.05). No complications such as secondary rupture of Achilles tendon occurred in the last follow-up of the three groups. [Conclusion] The long-term therapeutic effect of three different suture methods for acute achilles tendon rupture is similar, but the incision of 3-hole loop method is smaller, which is more conducive to the early recovery of achilles tendon function.
