To investigate the application effect of fusiform needle and thread technique and Krackow suture in patients with Achilles tendon rupture at or near the Achilles tendon and their influence on the Achilles tendon function.

A total of 106 patients with Achilles tendon rupture at or near the Achilles tendon from January 2021 to December 2022 admitted to Department of Hands and Foot, the Fourth People′s Hospital of Hengshui were included as the study objects and grouped by random number table method, and each group had 53 patients. The control group was given proximal Krackow suture combined with distal transcalcaneal bone tunnel suture, and the study group was given spindle needle combined with distal transcalcaneal bone tunnel suture.Surgery-related indexes, the good rate of Achilles tendon function, and achilles tendon total rupture score(ATRS)scores of the two groups were compared, and the incidence of postoperative Achilles tendon rupture and complications were recorded.

Incision length [(4.55±1.03) cm], incision healing time [(3.44±1.08) d] and hospitalization time[(3.86±1.13) d] in the study group were shorter than the control group [(6.72±1.30) cm, (4.07±1.45) min, (4.48±1.34) d](t_{incision length}=9.525, t_{incision healing time}= 2.537, t_{hospitalization time}= 7.559, P< 0.05).The intraoperative blood loss [(133.53±20.39) ml ]was lower than the control group[(157.14±23.26) ml](t= 5.557, P< 0.05). The excellent and good rate of the study group (94.34%) was higher than the control group (81.13%) (χ²=4.296, P< 0.05). The ATRS score of the study group was higher than the control group at 3 months after operation (t=2.815, P< 0.05). The incidence of tendon rupture at 1 months (1.89%) and 3 months (0.00%) in the study group was lower than that in the control group (13.21% and 7.55%) (χ_{1 months}²=4.867, χ_{3 months}²=4.157, P<0.05). The complication rate of the study group (1.89%) was lower than the control group (13.21%) (χ²=4.867, P< 0.05).

The treatment effect of fusiform needle technique combined with distal transcalcaneal tunnel suture is better than that of proximal Krackow suture combined with distal transcalcaneal tunnel suture in the treatment of patients with Achilles tendon rupture at or near the Achilles tendon, which can quickly restore the Achilles tendon function of patients and reduce the incidence of recent postoperative Achilles tendon rupture and complications.
