Abstract. Introduction. Anxiety and depression are risk factors for poor outcome following knee replacement surgery. The aim of this study was to investigate the prevalence of anxiety and depression before and after primary (pKR) and revision knee replacement (rKR). Methodology. Retrospective cohort study. 315,720 pKR and 12,727 rKR recruited from the NHS Patient Reported Outcome Measures (PROMs) programme from 2013–2021. Anxiety and depression were defined using: (i) Survey question: “Have you been told by a doctor that you have depression? Yes/No”; (ii) EQ-5D anxiety/depression domain. Rates of EQ-5D anxiety/depression were investigated at baseline and at 6-months following surgery. The prevalence of depression was investigated by patient age and gender. Results. Overall, 28,434/315,720 (9.0%) pKR and 1,536/12,727 (12.0%) rKR reported pre-operative depression. For all age groups, depression was more common in female than male patients. Prevalence of depression reduced with age (<60 years: 16.8% pKR, 22.7% rKR; 80+ years: 5.3% pKR, 5.2% rKR). Depression was most prevalent in female patients, under 60 years undergoing rKR (25.6%). Pre-operation, 109,000/303,998 (35.9%) pKR and 5,433/12,216 rKR (44.5%) reported moderate or extreme EQ-5D anxiety/depression. Post-operation, 65,351/308,914 (21.2%) pKR and 4,176/12,409 rKR (33.7%) reported moderate or extreme EQ-5D anxiety/depression. Conclusion. Anxiety and depression were prevalent in patients undergoing knee replacement surgery. Patients undergoing revision procedures, female patients and younger patients had the highest rates of depression. Large improvements in anxiety/depression were observed at early follow-up after pKR and rKR

SARS-CoV-2 emerged in Wuhan, China in December 2019 causing pneumonia and resulting in a pandemic, commonly known as COVID-19. This pandemic led to significant changes to our daily lives due to restrictions, such as social distancing, quarantining, stay at home orders and closure of restaurants and shops among other things. The psychological effects of this uncertainty as well as of these changes to our lives have been shown to be significant. This study is a prospective study investigating the mental effects of the pandemic on hand and wrist patients seen in our clinic during this pandemic. A prospective database on wrist pain was used to identify patients seen in our hand clinic from January 1, 2018 to December 10, 2021. All participants had been diagnosed with either radial sided wrist pain or ulnar side wrist pain. The Center for Epidemiological Studies Depression (CES-D) Scale was used to assess the mental health of our participants before and during this pandemic. An independent samples t-test was used to compare the scores of the 2 groups. A total of 437 CES-D questionnaires were collected during this period. 118 of them belonging to the pandemic group and 319 to the pre-pandemic group. A difference (p < 0 .05) in the CES-D score was observed between the pre-pandemic and during pandemic groups. The mean score for the pre-pandemic group was found to be 9.23 (8.94) and 12.81 (11.45) for the pandemic group. However, despite the increase in score, it didn't exceed the cut off score of 16 or greater used to assess depression. Our results indicate that there was a slight increase in score for depression in hand and wrist patients, but not above the cut off level of 16 to be of a significant risk for depression. Other global studies have shown an increase in depression in the general public. Our mild results might be attributed to the fact that British Columbia did not implement severe restrictions compared to other countries or regions, i.e no stay at home orders. Additionally, our study population was skewed and included more middle age and older patients compared to younger ones and age might be a factor in keeping the score down

Introduction. Patients undergoing TJA have higher rates of anxiety and/or depression than the general population and higher costs of care. These preoperative diagnoses lead to higher levels of postoperative dissatisfaction and depression patients alone have higher readmission rates. There is significant crossover between anxiety and depressive disorders, and many patients are classed as combined. Our goal was to evaluate readmission rates of patients undergoing total hip or knee arthroplasty with diagnoses of anxiety, depression or both. Methods. Our hospital's prospectively collected data from our statewide total joint database (MARCQI) was reviewed from 2013–2018. Rates of anxiety and/or depression were determined based preoperative anxiolytic or antidepressant medications using national drug codes. Independent sample t-tests compared continuous variables and Chi-square tests (or Fisher's exact tests) compared categorical variables. Potential risk factors were identified by multivariable logistic regression modeling. Results. 4,107 cases (1,261 THA and 2,846 TKA) were included. 176 patients (4.28%) had a readmission within the 90-day global period. 476 patients (12%) had history of depression or anxiety or both. For the entire cohort, those on anxiolytic medication were 153% more likely to be readmitted than those not on medication (p=0.017). When patients were stratified based on THA or TKA, patients taking anxiolytic medication undergoing TKA were 120% more likely to undergo readmission within 90 days (p=0.021). Patients on depression medication alone were not at increased risk of readmission in the TKA cohort (p=0.991). For THA patients neither diagnosis appeared a risk factor for readmission (p=0.852). Conclusions. Patients with depression, anxiety, or both undergoing TKA were at a statistically significant risk of readmission within 90-days compared to patients without these diagnoses. Anxiety and depression were both risk factors for readmission, but anxiety appeared to have a more significant impact. THA on the other hand did not appear to share this risk profile

We aimed to determine the rate of and risk factors for post-traumatic osteoarthritis (PTOA) and total knee arthroplasty (TKA) requirement after operative management of tibial plateau fractures (TPF) in older adults. We conducted a retrospective cohort study of 182 operatively managed TPFs in 180 patients ≥60 years old over a 12-year period with minimum follow up 1 year. Data including patient demographics, clinical frailty scores, mechanism of injury, management, reoperation and mortality were recorded. Radiographs were reviewed for: Schatzker classification; pre-existing knee osteoarthritis (KOA); severe joint depression >15mm; and development of PTOA. Kaplan Meier survival analysis was performed. Regression analysis was used to identify risk factors for radiographic indication for TKA and actual TKA. Forty-seven percent were Schatzker II fractures. Radiographic KOA was present at fracture in 32.6%. Fracture fixation was performed in 95.6% cases and acute TKA in 4.4%. Thirteen patients underwent late TKA (7.5%). At five-years, 11.8% (6.0-16.7 95% CI) had required TKA and 20.9% (14.4-27.4 95% CI) had a radiographic indication for TKA. Severe joint depression and pre-existing KOA were associated with worse survival for endpoints radiographic indication for TKA and actual TKA. Severe joint depression (HR 2.49(1.35-4.61 95% CI), p=0.004), pre-existing KOA (HR 2.23(1.17-4.23), p=0.015) and inflammatory arthropathy (HR 2.4(1.04-5.53), p=0.039) were independently associated with radiographic indication for TKA. In conclusion, severe joint depression and pre-existing arthritis are independent risk factors for both severe PTOA and TKA after TPFs in older adults. These features should be considered as an indication for primary management with acute TKA

Chronic low back pain (CLBP) is the most common cause of disability worldwide, and lumbar spine fusion (LSF) is often chosen to treat pain caused by advanced degenerative disease when clinical treatment failed certain cases, the post-surgical outcomes are not what was expected. Several studies highlight how important are. In psychological variables during the postoperative spine surgery period. The aim of this study is to assess the role of preoperative depression on postoperative clinical outcomes. We included patients who underwent LSF since December 2021. Preoperative depression was assessed administering Beck Depression Inventory questionnaire (BDI). And pain and disability were evaluated at 1, 3, and 6 months, administering respectively Visual Analogic Scale (VAS) and Oswestry Disability Index (ODI). As statistical analysis Mann-Whitney test was performed. We included 46 patients, 20 female (43,5%) and 26 male (56,5%) with an average age of 64,2. The population was divided in two groups, fixing the BDI cut-off point at 10. Patients with BDI < 10 points (N=28) had normal mental health status, instead patients with BDI > 10 points (N=16) had depressive disorders. At 3 months patients with healthy mental status reported statistically significant reduction of pain (U = 372,5, p = .006) and improvement of disability but without statistical significancy (U = 318, p = 0,137). At 6 months patients without psychological disease reported statistically significant reduction of pain (U = 342, p = 0,039) and disability (U = 372,5, p = 0,006). This study demonstrates the correlation between pre-existing depressive state and poorer clinical outcomes after spine surgery. These results are consistent with the literature. Therefore, during the surgical decision making it is crucial to take psychological variables into account in order to predict the results after surgery and inform patients on the potential influence of mental status

Mental disorders in particular depression and anxiety have been reported to be prevalent among patients with spinal pathologies. Goal of the current study was to analyze the relationship of Zung pre- and post-op score to other PROs and length of stay. Secondary outcomes included revision surgery and post-operative infections. Data from the international multicenter prospective spine degenerative surgery data repository, DegenPRO v1.1 (AO Spine Knowledge Forum Degenerative) were utilized. Patients undergoing cervical or lumbar procedure were included. Patient's demographics, Charlson Comorbidity Index, surgical information, Zung score, NDI, pain related PROs and EQ-5D, and complications at surgery and at various post-op time periods. Except for hospital duration, data were analyzed, using multivariable mixed linear models. A robust linear regression model was used to assess the association between Zung score and hospital duration. All models were adjusted for gender and age. 42 patients had Zung score administered. Among those patients 22 (52%) were within normal range, 18 (43%) were mildly and 2 (5%) severely depressed. 62% of the patients had a lumbar pathology with fusion procedures being the most common. Median EQ-5D (3L) score at surgery was significantly higher (0.7, IQR: 0.4-0.7) for patients within normal range than for those with mild (0.4, IGR: 0.3-0.7) or severe depression (0.3, IQR: 0.3-0.3, p-value: 0.05). Compared to patients within normal Zung range, mixed models, indicated lower EQ-5D (3L) score values and higher values for neck and arm pain at surgery with both PROs and EQ-5D (3L) improving in patients with depression over the follow-up time. No association was found between Zung score and hospital length of stay. The initial analysis showed that 43% of the patients were mildly depressed and mainly male patients. Zung score was correlated with post-operative improvements in EQ-5D and arm and neck pain PROs

Introduction. Depression is a common co-morbidity in Total Hip Arthroplasty (THA). Chronic pain and depression influence one another. Postoperative outcomes and satisfaction rates are affected by depression. Objectives. The aim of the study was to determine the impact of pre-operative depression on patient functional outcomes and satisfaction rates after THA. A secondary objective was to assess potential change in the incidence of depression at mid-term post-operative follow-up. Study Design & Methods. We retrospectively reviewed 200 patients undergoing THA from 2015–2016 at a single academic institution.150 (75%) of patients were followed up at a minimum of 24 months. Patients pre-operative depression symptoms were assessed according to the Zung Self-reported depression score and the PHQ-9 scores. Functional scores, satisfaction rates, expectation rates and 30- and 90-day readmission rates were correlated with pre-operative and 2-year follow-up depression scores. Results. There were 103 females and 47 males with an average age of 60.1 years (22–89 years old). The Patient Health Questionnaire (PHQ-9) correlated with the Zung Self-reported depression scores. Overall, 73 patients (48.7%) were classified as being depressed pre-operatively. There were 48 (32.2%) with mild depression and 19 (12.8%) with marked depression. Females, HIV-infected and morbidly obese patients were more likely to be depressed. The mean pre-operative Harris Hip Score (HHS) was 35.95 (24–66) and Oxford Hip Score (OHS) 17.11 (0–48). The 30-day readmission rate was 2% and all patients were pre-operatively severely depressed. At a minimum of 2 years there was an improvement in Zung Self-Rating Depression Scale and PHQ-9 scores. Only 29 (18.8%) patients were depressed. There were 55 patients who progressed from depressed to non-depressed (p=0.00), while 11 patients (7.4%) became depressed after THA (p=0.00). The least improvement in both OHS and HHS was in the severely depressed group (p<0.05). The overall satisfaction rate was 89.7%. Depressed patient satisfaction rate was 86.9% with only 70.27% of the severely depressed group satisfied post-operatively. Age (>70) and BMI >40 correlated with dissatisfaction (p<0.05). Conclusions. There is a high prevalence of depression in THA. Incorporation of psychological management strategies may improve satisfaction rates and functional outcomes post-THA

Background. Patients requiring lower limb reconstruction have often undergone significant trauma. In some patients this is a consequence of self-harm, others develop depression as a result of the accidental trauma that caused their injury. Little is known of the extent of the problem and how it changes over the course of their treatment. Design and Methods. Patients undergoing limb reconstruction in a major trauma centre were asked to complete an online questionnaire on the day of surgery. This included a Zung self-rating depression score, LEFS and EQ5D. They were asked to complete these again at subsequent post-operative time points. Results. Provisional results showed that all 3 outcome measures fluctuated over 6 months. Most patients triggered for at least mild depression on the Zung Self Rating Depression score at one or more time points. Not all patients had completed the questionnaire at all time points. Of those who did complete multiple time points, there was variation in the change in LEFS. Conclusion. Patients undergoing lower limb reconstruction are vulnerable to depression. There may be a correlation between mood and lower limb function. Gaining better understanding of these problems and how they change over time could help direct services to improve support for these patients

The relationship between pain catastrophizing and emotional disorders including anxiety and depression in patients with hip or knee osteoarthritis undergoing total joint replacement (TJR) is an emerging area of study. The purpose of this study was to examine the association between catastrophizing, anxiety, depression and postoperative pain and functional outcomes following primary TJR. A prospective cohort study of preoperative TJR patients at one academic arthroplasty centre over a one-year period was conducted. Pain catastrophizing was assessed using the Pain Catastrophizing Scale (PCS), and anxiety/depression using the Hospital Anxiety and Depression Scale (HADS-A, HADS-D) at preoperative assessment. Postoperative outcomes at one-year included patient perceived level of hip/knee pain using a visual analogue scale (VAS), subjective perception of function using the Oxford Hip/Knee Scores, and objective function using the Knee Society Score (KSS) and Harris Hip scores (HHS). Median regression was used to assess pattern of relationship between preoperative PCS clinically relevant catastrophizing (CRC), abnormal HADS-A, abnormal HADS-D and postoperative outcomes at one-year. Median difference and 95% confidence interval (CI) were reported. T-tests were performed to determine mean differences in postoperative outcomes among patients with PCS CRC, abnormal HADS-A, and abnormal HADS-D scores versus those with normal scores at preoperative assessment. P-values less than 0.05 were considered statistically significant. The sample included 463 TJR patients (178 hips, 285 knees). Both the PCS-rumination CRC sub-domain (median difference 1, 95% CI 0.31–1.69, p=0.005) and abnormal HADS-A (median difference 1, 95% CI 0.36–1.64, p=0.002) were identified as significant predictors of one-year VAS pain. PCS-magnification CRC sub-domain was also identified as a significant predictor of KSS/HHS at one-year (median difference 1.3, 95% CI −5.23–0.11, p=0.041). Preoperative VAS pain, Oxford and HHS/KSS scores were significantly inferior in patients who had CRC PCS, abnormal HADS-A, and abnormal HADS-D scores compared to patients with normal scores. At one-year, PCS CRC patients also had significantly inferior VAS pain (p=0.001), Oxford (p < 0 .0001) and KSS/HHS (p=0.025). Abnormal HADS-A and HADS-D patients experienced significantly inferior postoperative VAS pain (HADS-A p=0.025, HADS-D p=0.030), Oxford (HADS-A p=0.001, HADS-D p=0.030), but no difference in KSS/HHS (HADS-A = 0.069, HADS-D = 0.071) compared to patients with normal PCS/HADS scores. However, patients with CRC PCS experienced significantly greater improvement in preoperative to postoperative VAS pain (p < 0 .0001), Oxford (p=0.003) and HHS/KSS (p < 0 .0001). Similarly, patients with abnormal HADS scores showed significant improvement in preoperative to one-year postoperative change scores, as compared to normal patients in VAS pain (HADS-A p=0.011, HADS-D p=0.024), KSS/HHS (HADS-A p=0.017, HADS-D p=0.031), but not Oxford (HADS-A p=0.299, HADS-D p=0.558). Patients who are anxious, depressed or who pain catastrophize have worse preoperative function and pain. Postoperatively, pain and functional outcomes are also inferior in such patients, however they do experience a significantly greater improvement in outcomes. Furthermore, it appears that rumination and anxiety traits predict pain levels postoperatively. Although these patients report higher levels of pain postoperatively, as compared to preoperative, great improvement can be expected following hip and knee TJR

Total joint arthroplasty (TJA) is often utilized to improve pain and dysfunction associated with end-stage osteoarthritis. Previous research has suggested that depression may negatively impact patient reported pain and function. The purpose of this study was to determine the effect of pre-operative depressive symptoms, using the Center for Epidemiologic Scale for Depression (CES-D) scale, on patient reported function and pain at one, three and six months following TJA, after controlling for the impact of age, sex, pain, joint replaced, and other comorbidities. This was a secondary analysis of a prospective cohort of 710 patients aged 40 years and older who underwent elective primary TJA in the Edmonton zone. Participants were recruited pre-operatively and reported socio-demographics, comorbid conditions and medications (including depression medications where appropriate), each participant also completed the Western Ontario McMaster (WOMAC) Osteoarthritis Index and the CES-D scale preoperatively. Participants then completed the WOMAC and CES-D scale again at one, three, and six months postoperatively. Risk-adjusted longitudinal data analysis using a linear mixed regression model was performed, controlling for age, sex, joint replaced, chronic pain, comorbidity, social support and employment status. THA participants had a mean age of 65.9±10.1 years and included 175 (57%) female while TKA participants had a mean age of 67.9±10.1 years and included 249 (61%) females. ‘Possible’ depressive symptoms (CES-D score 16–19) were identified in 58 (8.1%) participants while ‘probable’ depressive symptoms (CES-D score ≥20) were identified in 68 (9.6%) participants. The mean WOMAC pain and function scores, when analyzed using the linear mixed regression model, demonstrated improvement from baseline at one, three, and six months (p < 0 .001 for both pain and function models as well as over time). However, in the patients with possible and probable depressive symptoms, WOMAC pain scores were 7.6±1.5 and 11.7±1.3 worse respectively than those without depressive symptoms after controlling for age, sex, joint replaced, chronic pain, comorbidities and social support. Similarly, WOMAC function scores in the patients with possible and probable depressive symptoms were 8.8±1.4 and 14.2±1.2 worse respectively than those without depressive symptoms after controlling for age, sex, joint replaced, comorbidities and employment status. Depressive symptoms negatively affect postoperative pain and function measured using WOMAC scales even after risk adjustment up to six-months post TJA. Screening for depressive symptomology both pre- and postoperatively may provide an opportunity to identify and manage depressive symptoms to improve postoperative pain and function

Depression and anxiety are widely prevalent amongst patients suffering from chronic diseases including osteoarthritis. National Institute for Clinical Excellence (NICE) guidelines recommend vigilance and routine screening in such chronic disease patients, and a recent King's Fund report found depression causes considerable expense to the NHS, with £1 for every £8 spent on chronic disease spent on patients mental health, costing between £8-13 billion annually. Depression increases length of hospital stay, and poorer clinical outcomes: depressed patients are 3.5 x as likely to die after suffering from myocardial infarction. Despite this, depression screening is not performed widely pre operatively. To see if there is a basis to recommend routine pre operative depression screening in hip and knee arthroplasty patients, we asked all patients attending Joint School to complete a Hospital Anxiety and Depression Scale (HADS). This is a well-validated tool for assessing the presence and degree (either mild, moderate or severe if present) of anxiety and depression, using fourteen questions, and providing a score out of 21 for each. We then correlated these results to pre operative Oxford Knee and Oxford Hip Scores to see if there was any relationship between the extent of impact of disease and any mood disorder present. 190 patients completed the questionnaire pre operatively. Of those, 82 (43%) scored as anxious. 73 (38%) scored as depressed. 47 (25%) scored as both. Overall 107 (56%) were either anxious, depressed or both. The median anxiety score was 7, with 44 (54%) scoring 8–10 (mild), 35 (43%) 11–15 (moderate) and 3 (4%) 16+ (severe). The median depression score was 6, with 53 (73%) scoring 8–10 (mild), 19 (26%) 11–15 (moderate) and 1 (1%) 16+ (severe). In order to look for an association between the severity of depression or anxiety and Oxford Scores, we grouped the Oxford Scores according to the patient's score on the HADS, and performed analysis of variance (ANOVA) to look for a significant difference between the Oxford Scores in the groups. There was no significant link between increase in Oxford Score and anxiety score (p=0.173314) but there was between Oxford Score and depression score (p=0.001377). There was equally no correlation between scores in patients classified simply as anxious or not anxious (p=0.14918) but a significant difference in Oxford Score was present between patients designated as depressed or not depressed (p=0.000297). We thus conclude depression and anxiety are very common amongst pre operative arthroplasty patients and thus assessment for this should be considered routinely preoperatively. In addition, there is a link between severity of osteoarthritis and severity of depression with increasing depression score associated with increasing Oxford Score. This makes further work to assess the reasons for this link imperative: does increasing severity of osteoarthritis result in increasing severity of depression, or does depression cause patients to feel the effects of their disease more keenly, and thus score higher on Oxford Scores? If this is the case, would patients treated for depression find the effect of their joint problems severe enough to warrant undertaking arthroplasty surgery?

The mean WOMAC pain and function scores, when analyzed using the linear mixed regression model, demonstrated improvement from baseline at one, three, and six months (p < 0 .001 for both pain and function models as well as over time). However, in the patients with possible and probable depressive symptoms, WOMAC pain scores were 7.6±1.5 and 11.7±1.3 worse respectively than those without depressive symptoms after controlling for age, sex, joint replaced, chronic pain, comorbidities and social support. Similarly, WOMAC function scores in the patients with possible and probable depressive symptoms were 8.8±1.4 and 14.2±1.2 worse respectively than those without depressive symptoms after controlling for age, sex, joint replaced, comorbidities and employment status. Depressive symptoms negatively affect postoperative pain and function measured using WOMAC scales even after risk adjustment up to six-months post TJA. Screening for depressive symptomology both pre- and postoperatively may provide an opportunity to identify and manage depressive symptoms to improve postoperative pain and function

The relationship between pain catastrophising and emotional disorders including anxiety and depression in patients with osteoarthritis (OA) undergoing total joint replacement (TJR) is an emerging area of study. The purpose of this study was to examine the association between pain catastrophising, anxiety, depression and preoperative patient characteristics. A prospective cohort study of preoperative TJR patients at one centre over 12-months was conducted. We examined association between catastrophising, anxiety, depression and preoperative patient characteristics including demographics, pain and function. Pain catastrophising was assessed using the Pain Catastrophising Scale (PCS), and anxiety/depression using the Hospital Anxiety and Depression Scale (HADS-A, HADS-D). Patient perceived level of hip/knee pain was measured using a visual analogue (VAS) pain scale. Patient perception of function was measured using the Oxford Score. Preoperative radiographic grading of OA was determined using the Kellgren and Lawrence (K-L) scale. Logistic regression was used to assess pattern of relationship between preoperative characteristics and PCS or HADS. Adjusted odds ratio (OR) and 95% confidence interval (CI) were reported. A secondary quantile regression analysis examined whether a model not restricted to pre-defined PCS and HADS categories would yield comparable results to the logistic regression model described in the primary analysis. P-values less than 0.05 were considered statistically significant. The sample included 463 TJR patients (178 hips, 285 knees). VAS pain (OR 1.23,95%CI 1.04–1.45) and Oxford score (OR 1.13,95%CI 1.07–1.20) were identified as significant predictors for PCS. The same two variables were the strong predictors for all sub-domains of PCS excluding rumination. Oxford Score was the only significant predictor for abnormal HADS-A (OR 1.10,95%CI 1.04–1.17) while VAS pain (OR 1.27,95%CI 1.02–1.52) and Oxford (OR 1.09,95%CI 1.01–1.17) were significant predictors for abnormal HADS-D. Similar pattern of association for PCS and HADS was observed in the quantile regression model, where larger VAS pain and Oxford scores significantly increased median PCS across all domains. Female gender, younger age or having a higher ASA grade were associated with higher median HADS-A, but unlike in the logistic regression, this association was statistically significant. Pain catastrophising and emotional disorders generally result in poor functional outcomes in TJR patients. The most important predictor of catastrophising, anxiety/depression is pain and subjective function. At risk patients include those with high preoperative pain with generally good preoperative function, as well as younger females with significant comorbidities. Such patients should be identified, and targeted psychological therapy implemented preoperatively to optimise coping strategies and adaptive behaviour to mitigate inferior TJR outcomes including pain and patient dissatisfaction

Study Design: To design and test a new questionnaire to assess depression and other mood states. Summary of Background Data: Measurement of depression and of other mood states in pain patients has been criticised in recent years on the grounds that most questionnaires were not developed in pain populations and suffer from criterion contamination by somatic items. In addition, there is no accepted measurement for positive emotions which are more than the absence of depression. Objective: To develop a reliable and brief tool to assess mood in pain patients. Method: Non-somatic items concerning depression, anxiety and positive outlook were extracted using exploratory factor analysis from commonly used instruments (Beck Depression Inventory and Hospital Anxiety and Depression Scale) completed by over 900 chronic pain patients. Confirmatory factor analysis was used to test the internal structure of the final item set. Items were then reworded and presented as a new questionnaire (the Depression, Anxiety and Positive Outlook Scale: DAPOS) to two new samples: patients attending pain management and patients attending osteopathy. The new questionnaire was compared with several well-known questionnaires (SF-36, BDI, PCS). The structure was calibrated and tested using confirmatory factor analysis on both samples. Finally, a sub-set of patients carried out a sorting task to test for face validity. Results and conclusion: The DAPOS performed well, indicating that it is a reliable measure of the three mood states with good initial evidence of validity in these samples

Approximately one-fifth of patients are not satisfied with total knee arthroplasty (TKA). Preoperative variables associated with poorer outcomes are severity and chronicity of pain and psychological disease, which may present as anxiety and depression. It is unclear whether this is constitutional or the result of knee pain. To address this, we explored the association of anxiety and depression with knee disability before and after TKA. Forty patients undergoing TKA completed Hospital Anxiety and Depression Scale (HADS) and Oxford Knee Scores (OKS) preoperatively and at three and six months postoperatively. Both were elevated preoperatively and improved significantly post-operatively (P<0.001). The severity of preoperative anxiety and depression was associated with worse knee disability (coefficient −0.409, p=0.009). Postoperatively reduction in anxiety and depression was associated with improvement in knee disability after three (coefficient −0.459, p=0.003) and six months (coefficient −0.428, p=0.006). The difficulty in interpreting preoperative anxiety and depression and the outcome of TKA is establishing whether they are the cause or effect of pain in the knee. As anxiety and depression improves with knee pain and function, this study suggests that knee pain contributes to the psychological symptoms and that a successful TKA offers an excellent chance of improving both

Nonsomatic items concerning depression, anxiety and positive outlook were extracted using exploratory factor analysis from commonly used instruments (the Beck Depression Inventory and the Hospital Anxiety and Depression Scale) completed by over 900 chronic pain patients. Confirmatory factor analysis was used to test the internal structure of the final item set. Items were then reworded and presented as a new questionnaire(the Depression, Anxiety and Positive Outlook Scale: DAPOS) to two new samples: patients attending pain management and patients attending osteopathy. The new questionnaire was compared with several well-known questionnaires (SF36, BDI, PCS). The structure was calibrated and tested using confirmatory factor analysis on both samples. Finally, a sub-set of patients carried out a sorting task to test for face validity. iii. The DAPOS performed well, indicating that it is a reliable measure of the three mood states with good initial evidence of validity in these samples

We reported a case of the acetabular depression fracture in conjunction with a central fracture dislocation of the hip that was treated with a unique surgical technique. CASE REPORT:. A 76-year-old man suffered a left acetabular fracture with severe left hip joint pain and walking disability. Acetabular fracture was not apparent on the initial radiographs including anteroposterior and oblique views of the pelvis. However, computed tomography (CT) scanning showed displaced acetabular depression fracture (a third fracture fragment) in the center of the weight-bearing area with fracture of the ilium and spontaneous reposition of central dislocation of the hip (Fig. 1, 2). It seemed that this fracture fragment created incongruity of the acetabular articular surface and the potential for hip joint instability. Therefore, the patient was treated with open reduction and internal fixation. SURGICAL TECHNIQUE:. To perform the procedure, the patient was placed in the lateral decubitus position. A direct lateral approach to the hip was used for exposure. The vastus lateralis was released 1 cm distal from its origin, trochanteric osteotomy was done by the Gigli saw. To observe the hip articular surface and to identify the fracture fragment, the femoral head was posterior dislocated with excision of teres ligamentum after T-shaped capsulotomy. The depressed fragment in the acetabulum was identified under direct vision but could not be reduced. Therefore, the outer cortex of the ilium was fenestrated in a size of 2 × 2 cm so that a 1-cm-wide levator was inserted to the depressed fragment at 2 cm proximal from the hip articular surface through the fenestrated window (Fig. 3). Subsequently, the displaced bone fragment was pushed down by using the levator to the adequate articular joint level. The fragment was stabilized with packed cancellous bone graft harvested from the osteotomized greater trochanter. The removed outer cortex of the ilium from fenestrated site was repositioned and fixed by a reconstruction plate and screws. The osteotomized greater trochanter was reattached and fixed with two cannulated cancellous hip screws. RESULTS:. At 9-month follow-up, he was pain-free and continued to function well without the use of external supports. The acetabular depression fracture was completely reduced and healed in the CT scanning evaluation. The patient had no signs of posttraumatic osteoarthritis in radiographs. DISCUSSION and CONCLUSION:. In acetabular fracture dislocations of the hip joint, the precise pathological anatomy is not easily demonstrated by routine radiographs with classification of acetabular fractures. In our case, however, details of acetabular fracture were not well visible on conventional radiographs. It has been shown that computed tomography is useful method in precise evaluation of the fracture type with bone damage and integrity of joint configuration. Concerning approach to the fracture fragment which existed in the center of the weight bearing area of acetabulum, we performed to fenestrate on the intact bony cortex of the ilium just proximal to the fracture site. It was convenient and useful to gain good reduction of the central acetabular depression fracture, although there was no report on such a ‘fenestration’ method

Objectives: To investigate the relationship between recall bias for pain stimuli in chronic low back pain patients and the cost of managing their back pain in primary care. Design: A retrospective cross-sectional investigation. Method: Sixty three low back pain patients were interviewed in a primary care setting. Information was gathered on their pain intensity, disability ratings, depression, anxiety, and duration of pain. They were also presented with a surprise recall test for pain descriptors. The cost of each patient’s treatment specifically for back pain in the previous 12 months was calculated. The relationship between the cost of back pain treatment and the scores from the interview were calculated first for total cost, and then for the breakdown of individual cost items. Results: Results indicated that recall bias for pain stimuli were significantly related to total cost (Rsq. = 8%). A detailed analysis revealed that pain intensity was related to the number of appointments with the general practitioners; depression scores related to the number of appointments with the in-house osteopaths; and recall bias for pain stimuli related to referrals to external experts (outpatients). A minority of patients high on recall bias was found to account for a disproportionate amount of the cost. Conclusion: Although no causal path can be deduced from the findings, the study provides a novel approach to measuring psychological factors in back pain in reference to health care utilisation. It is limited by its retrospective design, and should be followed by prospective studies to fully understand the relationship between cognitive bias and utilisation of health services

Aims. Scoliosis is a lateral curvature of the spine with associated rotation, often causing distress due to appearance. For some curves, there is good evidence to support the use of a spinal brace, worn for 20 to 24 hours a day to minimize the curve, making it as straight as possible during growth, preventing progression. Compliance can be poor due to appearance and comfort. A night-time brace, worn for eight to 12 hours, can achieve higher levels of curve correction while patients are supine, and could be preferable for patients, but evidence of efficacy is limited. This is the protocol for a randomized controlled trial of ‘full-time bracing’ versus ‘night-time bracing’ in adolescent idiopathic scoliosis (AIS). Methods. UK paediatric spine clinics will recruit 780 participants aged ten to 15 years-old with AIS, Risser stage 0, 1, or 2, and curve size (Cobb angle) 20° to 40° with apex at or below T7. Patients are randomly allocated 1:1, to either full-time or night-time bracing. A qualitative sub-study will explore communication and experiences of families in terms of bracing and research. Patient and Public Involvement & Engagement informed study design and will assist with aspects of trial delivery and dissemination. Discussion. The primary outcome is ‘treatment failure’ (Cobb angle progression to 50° or more before skeletal maturity); skeletal maturity is at Risser stage 4 in females and 5 in males, or ‘treatment success’ (Cobb angle less than 50° at skeletal maturity). The comparison is on a non-inferiority basis (non-inferiority margin 11%). Participants are followed up every six months while in brace, and at one and two years after skeletal maturity. Secondary outcomes include the Scoliosis Research Society 22 questionnaire and measures of quality of life, psychological effects of bracing, adherence, anxiety and depression, sleep, satisfaction, and educational attainment. All data will be collected through the British Spine Registry. Cite this article: Bone Jt Open 2023;4(11):873–880
