To analyze the efficacy and prognosis of incision reduction and fixation combined with Different methods of ligament repair for ankle fracture combined with lower tibiofibular anterior ligament rupture, and to provide relevant references for the rehabilitation of patients with this disease.

The clinical data of 57 patients with ankle fracture combined with lower tibiofibular anterior ligament rupture from October 2021 to October 2022 in our hospital were analyzed. The patients were divided into group A (30 cases) and group B (27 cases) according to their treatment modes.Both groups were treated with incision and repositioning combined with ligament repair, group A used deltoid ligament repair, and group B used lower tibiofibular combined screw fixation repair. Observe the clinical efficacy and prognosis of the two groups.

The hospital stay (15.66±2.12) and fracture healing time (11.44±2.00) in Group A were significantly shorter than those in Group B (18.70±2.45 and 13.56±2.01, respectively), with t-values of 5.022 and 3.986, and both P<0.05. Repeated measures ANOVA for VAS scores at 1 month and 3 months postoperatively between Group A and Group B showed statistically significant differences between the groups, with an interaction between group and time point. Differences between the two groups were statistically significant at all time points except preoperatively; the VAS scores in both Group A and Group B decreased in the order of 3 months postoperatively <1 month postoperatively < preoperatively (P<0.05). Additionally, the VAS scores in Group A were significantly lower than those in Group B at 1 month postoperatively (P<0.05). Repeated measures ANOVA for Baird-Jackson scores at 3 months and 6 months postoperatively between Group A and Group B also revealed statistically significant differences between the groups, with an interaction between group and time point. Differences between the two groups were statistically significant at all time points except preoperatively; the Baird-Jackson scores in both Group A and Group B increased in the order of preoperative <3 months postoperative <6 months postoperative (P<0.05). Furthermore, the Baird-Jackson scores in Group A were significantly higher than those in Group B at both 3 months and 6 months postoperatively (P<0.05). At 6 months postoperatively, the excellent and good rate in Group A (93.33%) was significantly higher than that in Group B (62.96%) (P<0.05). There was no statistically significant difference in the incidence of postoperative complications between the two groups (P>0.05).

Compared with lower tibiosis combined screw fixation repair, trigonal ligament repair showed significant advantages in length of hospitalization, fracture healing time, pain relief, recovery of ankle joint function, and excellent rate.
