RESUMO
INTRODUCTION: Single-item questions assessing patient satisfaction following total hip or knee arthroplasty (THA/TKA) provide immediate and comprehensible information. However, they have limited reliability as satisfaction as a concept is influenced by factors unrelated to surgery. The aim of this retrospective study was to evaluate variation in pain, function and joint awareness relative to the patients' satisfaction response following THA/TKA. METHODS: We analysed absolute and improvement scores on the Oxford Knee or Hip score (OKS or OHS) and the Forgotten Joint Score-12 (FJS-12) across satisfaction groups. Patient-reported outcome measures were assessed prior to surgery and at 12-month follow-up. Postoperative satisfaction was assessed using a 5-point Likert scale single-item question. RESULTS: We analysed data from 434 TKA patients (mean age 70.4 ± 9.2 years; 54.8% female) and 247 THA patients (mean age 67.3 ± 11.8 years; 57.5% female). Satisfied or very satisfied patients showed higher absolute scores and better improvement in function, pain and joint awareness at 12 months (both, p < 0.001). 13.4% of (very) satisfied THA patients scored equally or worse on the FJS-12 than before surgery. On the OHS, this percentage was 2.8%. In TKAs, these percentages were 7.0% on the FJS-12 and 3.2% on the OKS. CONCLUSIONS: While higher satisfaction is associated with better patient-reported outcomes and stronger postoperative improvement, a certain percentage of patients score poorly while reporting a high satisfaction. Our results highlight the difficulty in interpreting the meaning of a single satisfaction question, as this provides limited information on patients' treatment outcome and may be biased by factors unrelated to the intervention.

BACKGROUND: Joint awareness was recently introduced as a new concept for outcome assessment after total knee arthroplasty (TKA). Findings from qualitative and psychometric studies suggest that joint awareness is a distinct concept especially relevant to patients with good surgical outcome and patients at late follow-up time points. The aim of this study was to improve the understanding of the concept of joint awareness by identifying situations in which patients are aware of their artificial knee joint and to investigate what bodily sensations and psychological factors raise a patient's awareness of her/his knee. In addition, we evaluated the relative importance of patient-reported outcome parameters that are commonly assessed in orthopaedics. METHODS: Qualitative interviews were conducted with patients being at least 12 months after TKA. The interviews focused on when, where and for what reasons patients were aware of their artificial knee joint. To evaluate the relative importance of 'joint awareness' after TKA among nine commonly assessed outcome parameters (e.g. pain or stiffness), we collected importance ratings ('0' indicating no importance at all and '10' indicating high importance). RESULTS: We conducted interviews with 40 TKA patients (mean age 69.0 years; 65.0% female). Joint awareness was found to be frequently triggered by kneeling on the floor (30%), climbing stairs (25%), and starting up after resting (25%). Patients reported joint awareness to be related to activities of daily living (68%), specific movements (60%), or meteoropathy (18%). Sensations causing joint awareness included pain (45%) or stiffness (15%). Psychological factors raising a patient's awareness of his/her knee comprised for example feelings of insecurity (15%), and fears related to revision surgeries, inflammations or recurring pain (8%). Patients' importance ratings of outcome parameters were generally high and did not allow differentiating clearly among them. CONCLUSIONS: We have identified a wide range of situations, activities, movements and psychological factors contributing to patients' awareness of their artificial knee joints. This improves the understanding of the concept of joint awareness and of a patient's perception of his/her artificial knee joint. The diversity of sensations and factors raising patient's awareness of their joint encourages taking a broader perspective on outcome after TKA.

PURPOSE: This study investigated the impact of body mass index (BMI) on improvement in patient outcomes (pain, function, joint awareness, general health and satisfaction) following total knee arthroplasty (TKA). METHODS: Data were obtained for primary TKAs performed at a single centre over a 12-month period. Data were collected pre-operatively and 12-month postoperatively with the Oxford Knee Score (OKS) measuring pain and function, the EQ-5D-3L measuring general health status, the Forgotten Joint Score-12 (FJS-12) measuring joint awareness and a single question on treatment satisfaction. Change in scores following surgery was compared across the BMI categories identified by the World Health Organization (< 25.0, 25.0-29.9, 30.0-34.9, 35.0-39.9 and ≥ 40.0). Differences in postoperative improvement between the BMI groups were analysed with an overall Kruskal-Wallis test, with post hoc pairwise comparisons between BMI groups with Mann-Whitney tests. RESULTS: Of 402 patients [mean age 70.7 (SD 9.2); 55.2% women] 15.7% were normal weight (BMI < 25.0), 33.1% were overweight (BMI 25.0-29.9), 28.2% had class I obesity (BMI 30.0-34.9), 16.2% had class II obesity (BMI 35.0-39.9), and 7.0% had class III obesity (BMI ≥ 40.0). Postoperative change in OKS (n.s.) and EQ-5D-3L (n.s.) was not associated with BMI. Higher BMI group was associated with less improvement in FJS-12 scores (p = 0.010), reflecting a greater awareness of the operated joint during activity in the most obese patients. Treatment satisfaction was associated with BMI category (p = 0.029), with obese patients reporting less satisfaction. CONCLUSIONS: In TKA patients, outcome parameters are influenced differently by BMI. Our study showed a negative impact of BMI on postoperative improvement in joint awareness and satisfaction scores, but there was no influence on pain, function or general health scores. This information may be useful in terms of setting expectations expectation in obese patients planning to undergo TKA. LEVEL OF EVIDENCE: Level 1.

AIMS: To validate the English language Forgotten Joint Score-12 (FJS-12) as a tool to evaluate the outcome of hip and knee arthroplasty in a United Kingdom population. PATIENTS AND METHODS: All patients undergoing surgery between January and August 2014 were eligible for inclusion. Prospective data were collected from 205 patients undergoing total hip arthroplasty (THA) and 231 patients undergoing total knee arthroplasty (TKA). Outcomes were assessed with the FJS-12 and the Oxford Hip and Knee Scores (OHS, OKS) pre-operatively, then at six and 12 months post-operatively. Internal consistency, convergent validity, effect size, relative validity and ceiling effects were determined. RESULTS: Data for the TKA and THA patients showed high internal consistency for the FJS-12 (Cronbach α = 0.97 in TKAs, 0.98 in THAs). Convergent validity with the Oxford Scores was high (r = 0.85 in TKAs, r = 0.79 for THAs). From six to 12 months, the change was higher for the FJS-12 than for the OHS in THA patients (effect size d = 0.21 versus -0.03). Ceiling effects at one-year follow-up were low for the FJS-12 with just 3.9% (TKA) and 8.8% (THA) of patients achieving the best possible score. CONCLUSION: The FJS-12 has strong measurement properties in terms of validity, internal consistency and sensitivity to change in TKA and THA patients. Low ceiling effects and good relative validity allow the monitoring of longer term outcomes, particularly in well-performing groups after total joint arthroplasty.

OBJECTIVE: To investigate cancer patients' understanding of graphical presentations of longitudinal EORTC QLQ-C30 scores. METHODS: We conducted semi-structured interviews with brain tumour patients participating in routine patient-reported outcome (PRO) monitoring. We assessed understanding of longitudinal quality of life (QOL) profiles, presented as bar charts objectively and with self-ratings. In addition, patients' opinions on congruency of the QOL scores with their self-perceived health status were evaluated. RESULTS: We recruited 40 brain tumour patients (57.5% female; mean age 52.7, SD 13.7). In total, 90% of patients rated the graphs as easy to understand. Accordingly, almost all questions on assessing understanding objectively were answered correctly by at least 80% of the patients. More than 95% indicated that the displayed QOL scores matched their personal perception of symptom burden and functional health in the observed period. CONCLUSION: Patients are able to understand their QOL results when presented graphically and are able to interpret important changes. Displayed QOL scores obtained with the EORTC QLQ-C30 are consistent with the patients' personal perception of physical and emotional functioning, pain and fatigue. PRACTICE IMPLICATIONS: Knowledge about patients' understanding of graphically displayed QOL results contributes to creation of optimal evidence-based feedback on the patients' present QOL and its trajectory.

BACKGROUND: The study investigated the development of theory-of-mind (ToM) knowledge in children with lesser variants' of autism (PDD-NOS) over a period thought to be critical for ToM development (i.e., 3 to 5 years of age). METHOD: The sample included 11 children with PDD-NOS; 23 normally developing children were included for cross-sectional comparison and 13 normally developing children for longitudinal comparison. The groups were comparable in verbal and non-verbal mental age. Two storybooks were used for repeated assessment of various aspects of the children's theory of mind: emotion recognition, the distinction between physical and mental entities, prediction of behaviour and emotions on the basis of desires and prediction of behaviour and emotions on the basis of beliefs. RESULTS: The results showed that the children with PDD-NOS had specific difficulties in understanding and predicting other people's emotions on the basis of situational cues, desires and beliefs. However, their ability to predict actions from beliefs and desires were relatively intact. Compared to the normally developing children, these children achieved lower levels of theory-of-mind knowledge, both at time of initial assessment and approximately 6 months later. CONCLUSIONS: The data suggest that the theory-of-mind development of children with PDD-NOS is both delayed and deviant. The growth pattem of theory-of-mind skills in children with PDD-NOS seemed to be qualitatively different from the growth pattern found in the group of normally developing children.
