Object: the purpose of this study is to investigate the occurrence of fear of movement after total knee arthroplasty and analyze its influencing factors, so as to provide theoretical basis for reducing the occurrence of fear of movement after total knee arthroplasty, promoting the rehabilitation exercise of patients and promoting the recovery of knee joint function. In this study, 121 patients with total knee arthroplasty were investigated by questionnaire, including general demographic data, sports fear scale, anxiety and depression scale, self-efficacy scale and so on.
