Purpose To evaluate the effects of kinesiophobia on both phases immediately after surgery and the final results after total knee arthroplasty (TKA). Methods This study evaluated prospectively 101 patients (mean age 66 ± 8.0 years, 70 women and 31 men), 5 days after surgery, at 1, 6, 12 months, and at a mean final follow-up of 3.2 ± 0.7 years (2.0–4.2 years). Kinesiophobia was assessed with the Tampa Scale for Kinesiophobia (TSK: Activity Avoidance—TSK1 and Harm—TSK2 subscales), and results were evaluated with range of motion, pain and function on 0–10 numeric rating scales, WOMAC and SF-12 (Physical and Mental subscales) scores. Results TSK1 was correlated with the acute postoperative pain measured at 5 days (p = 0.031), pain measured at 12 months (p = 0.018), patient perceived function at 12 months (p = 0.025), SF-12P at 6 months (p < 0.001), SF-12P and SF-12M at 12 months (p = 0.001 and p = 0.005, respectively), and WOMAC at both 6 and 12 months of follow-up (p = 0.005 and p = 0.001). The effect of TSK 1 on the final WOMAC score was significant when corrected by age and sex (p = 0.049, η 2 = 0.041): the youngest female patients were affected even by moderate kinesiophobia levels. Conclusions Fear of pain and even more avoidance of movement are strongly correlated both with the acute postoperative pain perception and recovery after surgery up to 1 year, thus presenting a relevant clinical impact on the outcome after TKA. Moreover, this study showed that even though at longer follow-up its impact decreases, patients with higher levels of kinesiophobia may present a poorer final outcome, especially women. Level of evidence IV.

Patient engagement in a patient–physician decision-making process has been correlated with satisfaction and clinical outcomes. Aim of this study is to evaluate if patient control preference may also influence TKA results. One hundred and seventy-six patients (120w–56m, age 66 ± 9 years, BMI 28 ± 4) underwent TKA and were prospectively evaluated, before surgery and at 6 and 12 months. The preoperative assessment included the Control Preference Scale (CPS) and other scales measuring psychological aspects (STAI, BDI, TSK), as well as SF12 (physical and mental subscales) and the assessment of pain and function. Pain, function, and SF12 subscales were then used to evaluate the improvement at 6- and 12-month follow-up. Pain, function, and SF12 scores improved at 6 and 12 months. CPS correlated with the outcome: pain and functional improvement at 6 months (p = 0.014; p = 0.003, respectively), patient function at 6 months (p = 0.022), improvement of SF12 physical subscale at 6 and 12 months (p = 0.027; p = 0.037, respectively), and satisfaction at 6 months (p = 0.033). Moreover, the multivariate analysis confirmed the importance of CPS regardless of other demographic, physical or psychological characteristics. In contrast with previous literature findings, this study shows that patients with more propensity for control presented lower improvements of pain and function than those more prone to rely on the physician making the decision. Physicians should be aware that the patient control preference may influence the treatment outcome and undertake measurements to optimize patient participation in the shared process to optimize the chances of TKA success.

In three general medical settings (general practice, hospital medical wards and emergency rooms) about 20% of the adult attenders had a DSM-III mental disorder, mainly in the area of affective and anxious disorders. Some of these disorders were quite severe. Of those cases reassessed 1 year and 2 years after the first interview, less than a quarter reached a "no-diagnosis status". The chronicity of most cases dependent on the interplay not only of either relapse or duration of the main disorder but also of comorbidity and incidence of new disorders. A high incidence of more transient disorders in subjects who were well at first assessment was also found.

To evaluate the effects of kinesiophobia on the outcomes of total knee arthroplasty (TKA), and to investigate whether kinesiophobia represents an independent factor influencing the surgery success or whether the observed effects are driven by other physical or psychological aspects such as anxiety and depression. Two hundred patients were evaluated prospectively (mean age 65.7 ± 9.1 years, 134 women and 66 men) at 12 months after TKA. Kinesiophobia was assessed with the Tampa Scale for kinesiophobia (TSK: Activity Avoidance—TSK1 and Harm—TSK2 subscales); anxiety and depression were assessed with STAI and BDI, respectively, and preoperative pain and function, sex, age, BMI, education level, number of painful joints and years of symptoms’ duration before surgery were documented as well. Results were evaluated with pain and function on 0–10 numeric rating scales, while the overall clinical outcome was documented with WOMAC and SF-12 (Physical and Mental subscales) scores. TSK1 was correlated with WOMAC results at 12 months (p = 0.005, ρ = 0.197). STAI (p = 0.002, ρ = 0.222), BDI (p
