Kinesiophobia is associated with quality of life after total hip arthroplasty: A short-term prospective observational study

Abstract

Abstract Background: Kinesiophobia and pain catastrophizing are key factors that affect outcomes after total knee arthroplasty. However, its impact on outcomes after total hip arthroplasty (THA) remains unclear. This study aimed to determine whether kinesiophobia, assessed by the Tampa Scale for Kinesiophobia (TSK)-11, and pain catastrophizing, assessed by the Pain Catastrophizing Scale (PCS), were associated with quality of life (QOL) at 12 months after THA. Methods: Ninety consecutively patients were evaluated prospectively at 12 months after THA. QOL scores were assessed by disease-specific QOL (the Japanese Orthopaedic Association Hip Disease Evaluation Questionnaire) and general QOL (the EuroQOL-5 Dimensions), pain intensity was used by Visual Analog Scale, and TSK-11 and PCS were evaluated pre-operative and at 12 months after THA. Each QOL score at 12 months was used for multivariate analysis. Results: Pain intensity and TSK-11 were independently correlated with the disease-specific and general QOL at 12 months after THA in the multiple regression analysis. PCS was not correlated with each QOL at 12 months after THA. Conclusions: Kinesiophobia and pain intensity were independently associated with disease-specific and general QOL at 12 months after THA. Higher kinesiophobia and pain intensity were potential factors that lower QOL at 12 months after THA.
