Abstract: Objective To investigate the effect of V-Y plasty combined with transposition of gastrocnemius aponeurosis on the repair of old rupture of Myerson Ⅲ Achilles tendon and the recovery of posterior Achilles tendon function and ankle joint.Methods 82 cases of old rupture of Achilles tendon of Myerson Ⅲ type treated in our hospital from January 2020 to January 2022 were selected as the research objects.According to the random number table,they were divided into the observation group (41 cases were treated with V-Y plasty combined with transposition of gastrocnemius aponeurosis) and the control group (41 cases were treated with V-Y plasty).The clinical effects of the two groups after treatment were observed [evaluated with Arner Lindholm efficacy evaluation standard] Achilles tendon function [evaluated by Achilles tendon rupture score (ATRS)],ankle joint function,pain [evaluated by pain rating index (PRI)],and complications.Results After treatment,the effective rate of observation group was 85.37%,which was higher than that of control group (60.98%) (P<0.05).Before operation,there was no difference in Achilles tendon function scores between the two groups (P>0.05).The scores of posterior Achilles tendon function in observation group were higher than those in control group 1,3 and 6 months after operation (P<0.05).The ankle joint function scores of observation group were higher than those of control group at 1,3 and 6 months after operation (P<0.05).Before surgery,there was no difference in pain scores between the two groups (P>0.05).The pain scores of the observation group were lower than those of the control group at 1,3 and 6 months after operation (P<0.05).After treatment,the total complication rate of observation group was 9.76%,which was lower than that of control group 31.71% (P<0.05).Conclusion V-Y plasty combined with transposition repair of gastrocnemius aponeurosis can improve the clinical efficacy of patients with Myerson Ⅲ old achilles tendon rupture,improve the function of posterior Achilles tendon and ankle joint,and reduce pain.
