[Objective]To explore the effect of self-efficacy intervention on kinetophobia in revision reconstruction of the anterior cru-ciate ligament due to military training injury.[Methods]Sixty patients with kinesophobia in revision reconstruction of anterior cruciate liga-ment(ACL)due to military training injury were included into this study from May 2022 to October 2023.Among them,30 patients admitted from February to October 2023 were given self-efficacy intervention(intervention group)on the basis of routine care,while other 30 pa-tients admitted between May 2022 and January 2023 received routine care(routine group).The numeric rating scale(NRS)scores for pain,Tampa Scale of Kinesiophobia(TSK-17)and general self-efficacy scale(GSES)were compared between the two groups.[Results]At admis-sion,there were no significant differences in pain NRS,TSK-17 and GSES scores between the two groups(P>0.05).Compared with those at admission,the pain NRS,TSK-17 and GSES scores significantly improved in both groups at discharge(P<0.05).At discharge,the interven-tion group proved significantly superior to the routine group in terms of NRS[(2.2±0.8),(2.7±0.7),P=0.006],TSK-17[(30.8±2.8),(33.3±1.8),P<0.001]and GSES scores[(32.9±2.5),(27.7±2.4),P<0.001].[Conclusion]Self-efficacy intervention can significantly reduce pain,reduce kinesiophobia and promote functional recovery in ACL revision reconstruction due to military training injury.
