ABSTRACT
Objective To study the effect of arthroscopic internal fixation combined with arthrodesis on patients with advanced ankle arthritis and American Orthopedic Ankle Association Scoring System (AOFAS) and visual analogue scale (VAS). Methods 84 patients with advanced ankle arthritis from January 2012 to January 2015 were randomly divided into experimental group (42 cases) and control group (42 cases) by random number method. The patients in the control group were treated with traditional open ankle arthrodesis, the experimental group under the arthroscopic assisted internal fixation joint fusion. Then compare the time of surgery, intraoperative blood loss, postoperative hospitalization time and complication. The follow-up period was 12 to 36 months. Used the AOFAS score system to evaluate the curative effect. Use VAS to evaluate the degree of ankle pain. Results The operation time and intraoperative blood loss were significantly lower in the experimental group than that in the control group (P < 0.05). The postoperative hospital stay and the time of joint fusion were lower in the experimental group than that in the control group (P < 0.05). The incidence of complication (9.52%) in the experimental group was significantly lower than that in the control group (25.57%) (P < 0.05). The results of follow-up showed that the VAS and AOFAS scores of the experimental group were better than those in the control group (P < 0.05). Conclusion The procedure of arthroscopic endoscopic fusion is short, the bleeding rate is low, the incidence of complications is low, the healing rate is high, and the follow-up effect is accurate. It is suitable for clinical use.
