Incidence and Risk Factors of Kinesiophobia After Total Knee Arthroplasty in Zhengzhou, China: A Cross-Sectional Study.

BACKGROUND

The incidence of and risk factors for kinesiophobia after total knee arthroplasty (TKA) have not been well characterized in the literature. Thus, the aim of this study was to investigate the incidence of postoperative kinesiophobia among patients undergoing TKA and to identify the associated risk factors.

METHODS

The simplified Chinese version of the Tampa Scale for Kinesiophobia, Knee Self-Efficacy Scale, Numerical Rating Scale, Simplified Coping Style Questionnaire, and Social Support Rating Scale were used to measure kinesiophobia, self-efficacy, pain intensity, coping styles and social support, respectively. Multivariate logistic regression analyses were utilized to identify the risk factors for postoperative kinesiophobia among TKAs.

RESULTS

A total of 862 participants were included in this study. Among all participants, 210 (24.4%) were identified as having kinesiophobia according the Tampa Scale for Kinesiophobia (TSK>37), with a mean score of 32.5 (standard deviation 13.1). A multivariate regression analysis showed that older age (odds ratio [OR] = 2.8, confidence interval [CI] = 2.0-3.7), lower education level (OR = 1.7, CI = 1.3-2.4), negative coping styles (OR = 1.6, CI = 1.0-2.2), less social support (OR = 3.5, CI = 3.1-4.1), lower self-efficacy (OR = 1.4, CI = 1.1-1.7), and greater pain intensity (OR = 2.8, CI = 1.5-5.3) are independent risk factors for kinesiophobia.

CONCLUSION

A 24.4% incidence rate of postoperative kinesiophobia was noted in patients following TKA. Older age (most notably ≥76 years old), lower education levels, negative coping styles, greater pain intensity, lower self-efficacy, and less social support were associated with odds of developing postoperative kinesiophobia.
