The effect of two kinds of modified brostrom surgeries on pain and aofas score in patients with lateral collateral ligament injury of ankle

Introduction: To investigate the effect of open and arthroscopically modified Brostrom surgery on pain and the American Orthopaedic Foot and Ankle Society (AOFAS) score in patients with lateral collateral ligament injury of the ankle. Materials and methods: 148 patients with lateral collateral ligament injury of ankle admitted to our hospital from July 2015 to July 2021 were enrolled retrospectively and divided into 2 groups according to different surgical procedures, that is, the control group (78 cases) who underwent open modified Brostrom surgery and the observation group (70 cases) who underwent arthroscopically modified Brostrom surgery. The surgery time, incision length, length of stay, visual analogue scale (VAS) score, AOFAS score and incidence of surgical complications of 2 groups were compared. Results: There was no significant difference between 2 groups in surgery time (P>0.05). The incision length and length of stay of the observation group were significantly lower than those of the control group (P<0.05). The VAS scores 1 week, 4 weeks and 24 weeks after surgery and at the last follow-up of 2 groups were significantly higher than those before surgery(P<0 .05). The VAS score of the observation group 1 week after surgery was significantly lower than that of the control group (P<0.05). The AOFAS scores 4 weeks, 24 weeks and 48 weeks after surgery and at the last follow-up of 2 groups were significantly higher than those before surgery (P<0.05). The AOFAS score of the observation group 4 weeks after surgery was significantly higher than that of the control group (P<0.05). There were no complications like incision infection, skin necrosis and vascular tendon injury after surgery. There was no significant difference between 2 groups in the incidence of superficial peroneal nerve injury (P>0.05). Conclusion: Compared with open surgery, arthroscopically modified Brostrom surgery can efficiently minimize surgical trauma and shorten the length of stay, which has advantages in improving early efficacy and excellent safety in the treatment of lateral collateral ligament injury of the ankle.
