Objective: The aim of this study was to assess the incidence and severity of kinesiophobia, and to determine the relationship between Tampa Scale of Kinesiophobia (TSK) scores, functional outcome and quality of life (QoL) 6-8 years after Total Hip Arthroplasty (THA).

Methods: 161 patients (78 male and 83 female) with unilateral primary osteoarthritis (OA) treated with THA between September 2010 and December 2013 were included in this study. Western Ontario and McMaster Universities Osteoarthritis (WOMAC) and EQ-5D scores were measured preoperatively. At 6-8 years follow-up, these scores were repeated and TSK scores were also measured. According to the TSK, patients were divided into two groups for further comparisons and analysis: without kinesiophobia (TSK-score ≤ 36) and with kinesiophobia (TSK-score >36).

Results: There were 99 patients (61.5%) with no kinesiophobia (TSK score ≤ 36, TSK mean 28.4, SD 4.7) and 62 patients (38.5%) with kinesiophobia (TSK score > 36, TSK mean 42.8, SD 5.3). Patients with and without kinesiophobia were not statistically different regarding age, sex or body mass index. (P = 0.20, P = 0.99, P = 0.22, respectively). In the group with no kinesiophobia, the mean 6-8 years WOMAC was 12.4 (SD 15.6), while the absolute delta (Δ) value between preoperative and 6-8 years WOMAC was 46.2 (SD 20.4), compared to the group with kinesiophobia where the mean 6-8 years WOMAC was 32.2 (SD 23.4), while the absolute delta (Δ) value between preoperative and 6-8 years WOMAC was 32.3 (SD 25.5): both P < 0.001. The group with no kinesiophobia had a mean 6-8 years EQ-5D of 0.81 (SD 0.22), while the absolute delta (Δ) value between preoperative and 6-8 years EQ-5D was 0.44 (SD 0.26), compared to the group with kinesiophobia where the mean 6-8 years EQ-5D was 0.57 (SD 0.23), while the absolute delta (Δ) value between preoperative and 6-8 years EQ-5D was 0.33 (SD 0.26): P < 0.001 and P = 0.03, respectively. TSK scores were associated with worse WOMAC and EQ-5D scores, higher proportion of dependence on walking aids and increased THArelated adverse events (all P < 0.05).

Conclusion: This study has shown us that there is a high incidence of kinesiophobia 6-8 years after surgery and treating kinesiophobia early after THA might improve the outcome.
