[Abstract] Objective: To study the effect of Krackow suture with limited incision near tendon for acute closed rupture of Achilles tendon and compare it with traditional open suture. Methods: The subjects were 92 patients with acute closed rupture of Achilles tendon admitted to our hospital from August 2016 to June 2018. In the study group, 44 patients underwent Krackow suture with limited incision near tendon, while in the control group, 48 patients underwent traditional open suture. The two groups of patients were compared by general surgical indicators, Arner-lindholm evaluation of the final follow-up, ankle and foot evaluation before and after treatment, postoperative complications and other evaluation indicators. Results: The incision length, operation time and intraoperative bleeding volume in the study group were significantly lower than those in the control group, with significant difference between the two groups (P < 0.05). The excellent and good rate of Arner-lindholm evaluation in the study group (97.73%) was significantly better than that in the control group (77.08%). The difference between the two groups was significant (P < 0.05). At the last follow-up, the AOFAS foot and ankle scores of the two groups were significantly improved compared with those before treatment, and the AOFAS foot and ankle scores of the study group were significantly better than those of the control group, the difference between the two groups was significant (P < 0.05). The incidence of complications in the study group (4.55%) was significantly lower than that in the control group (14.58%). There was a significant difference between the two groups (P < 0.05). Conclusion: Krackow suture with limited incision beside tendon is safe, minimally invasive and efficient in the treatment of acute closed rupture of Achilles tendon. It can effectively reduce the operation time, avoid injuring sural nerve by mistake, prevent complications such as wound infection and recurrence after operation, and is conducive to the improvement of clinical symptoms and recovery of nerve function.
