Efficacy of internal splint enhanced fixation for anatomical repair of deltoid ligament injury under total arthroscopy
Objective:To compare the clinical efficacy of internal splint enhanced fixation for anatomical repair of deltoid ligament injury under total arthroscopy with the traditional direct suture repair method.Methods:The clinical data of 36 patients with ankle fracture complicated with deltoid ligament injury admitted from February 2018 to November 2021 were retrospectively analyzed.Patients were divided into two groups based on their preference for surgical method:endoscopic surgery group(n=1 8)and open surgery group(n=18).All patients underwent fracture reduction and internal fixation,with the deltoid ligament treated.In the endoscopic surgery group,the deltoid ligament injury was repaired using internal splint reinforcement technology under total arthroscopy,while in the open surgery group,the deltoid ligament was sutured with thread rivets.The pre-and post-operative visual analogue scale(VAS)scores were compared between the two groups;the incidence of complications one year postoperatively was also compared.At the final follow-up,ankle mobility(maximum dorsiflexion angle and maximum plantar flexion angle),imaging results(passive maximum eversion angle of the ankle joint,stress position X-ray medial malleolus space),excellent rate of ligament repair,and patient satisfaction were compared between the two groups.Results:All patients underwent successful surgery and were followed up for 10 to 18 months postoperatively,with an average follow-up of(14.5±2.2)months.The 12-month follow-up results showed that the maximum dorsiflexion angle and maximum plantar flexion angle in the endoscopic surgery group were greater than those in the open surgery group.The maximum eversion angle and medial ankle space in the endoscopic surgery group were smaller than those in the open surgery group.The excellent rate of ligament repair and patient satisfaction rate in the endoscopic surgery group were higher than those in the open surgery group(both P＜0.05).The VAS score of the endoscopic surgery group at 12 months postoperatively was lower than that of the open surgery group(P＜0.05).Conclusions:Anatomical repair of deltoid ligament injuries with internal splint enhanced fixation under total arthroscopy is beneficial to the early recovery of ankle function and the relief of joint pain,while also taking advantage of minimally invasive treatment.
