Abstract:[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 admittedfrom 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 atadmission, 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.
