Abstract 【Objective】To investigate the clinical value of suture anchor in the repair of ankle fracture complicated with complete rupture of deltoid ligament. 【Methods】The clinical data of 69 patients with ankle fracture combined with complete rupture of deltoid ligament in our hospital from January 2015 to January 2020 were retrospectively analyzed. The patients were divided into the repair group (n=36) and the non-repair group (n=33) according to whether suture anchor was used to repair the deep deltoid ligament. The changes of medial space (MCS), American Association of foot and ankle surgeon's ankle-hindfoot score (AOFAS) and visual analogue scale (VAS) at 1 month and 6 months after operation, and the range of motion of ankle joint at 6 months after operation were compared between the two groups to evaluate the clinical efficacy and safety of the two groups. 【Results】The AOFAS scores of the two groups at 6 months after operation were higher than those at 1 month after operation, while the VAS scores were lower than those at 1 month after operation. The MCS and VAS scores of the repair group at 1 month and 6 months after operation were lower than those of the non-repair group, and the AOFAS scores were higher than those of the non-repair group. At 6 months after operation, the toe flexion and back extension angles of the repair group were higher than those of the non-repair group, and the clinical excellent and good rate was higher than that of the non-repair group (86.11% vs 69.70%). The differences were statistically significant (all P<0.05). The incidence of postoperative complications in the repair group was 2.78%, which was lower than 21.21% in the non-repair group (P<0.05). 【Conclusion】Suture anchor repair of deep deltoid ligament can promote ankle function recovery, reduce postoperative pain, and reduce the risk of postoperative complications such as poor reduction in patients with ankle fracture combined with complete tear of deltoid ligament.
