Abstract Objectives Relapsing polychondritis (RP) is a rare, heterogeneous, systemic inflammatory disease that targets cartilage. Patient-reported outcome measures may differ from physician assessment. This study compared patient global assessment (PtGA) and physician global assessment (PhGA) scores in a prospective cohort of patients with RP. Methods Adult patients with RP underwent a standardized comprehensive evaluation at ∼6 month intervals. At each visit, three physicians scored PhGA by consensus. The patient independently completed four patient-reported outcomes: PtGA, 36-item Short Form Health Survey (SF-36), Brief Illness Perception Questionnaire (BIPQ) and Multidimensional Fatigue Inventory (MFI). Patient–physician discordance was defined as a difference between PtGA and PhGA of ≥3 on a 0–10 scale. Results A total of 76 patients were evaluated over 154 visits. The median PhGA was 3 [interquartile range (IQR) 2–3] and the median PtGA was 5 (IQR 4–7). PtGA and PhGA were concordant in 66 visits (42.9%) and patients scored disease severity ≥3 points higher than physicians scored disease activity (positive discordance) in 84 visits (54.5%). Compared with visits with concordance, visits with positive discordance were associated with significantly worse scores on the MFI, BIPQ, SF-36 physical component score and SF-36 mental component score. Conclusion Patients with RP typically self-report high PtGA that does not align with PhGA. Discordance is likely driven by the high physical and psychological burden of illness experienced by patients. Multifaceted treatment approaches that address the burden of disease in RP from the patient perspective are needed.

Aims The aim of this study was to investigate the efficacy of coccygectomy in patients with persistent coccydynia and coccygeal instability. Methods The Danish National Spine Registry, DaneSpine, was used to identify 134 consecutive patients who underwent surgery, performed by a single surgeon between 2011 and 2019. Routine demographic data, surgical variables, and patient-reported outcomes, including a visual analogue scale (VAS) (0 to 100) for pain, Oswestry Disability Index (ODI), EuroQol five-dimension questionnaire (EQ-5D), and the Physical Component Score (PCS) and Mental Component Score (MCS) of the 36-Item Short-Form Health Survey questionnaire (SF-36) were collected at baseline and one-year postoperatively. Results A total of 112 (84%) patients with a minimum follow-up of one year had data available for analysis. Their mean age was 41.9 years, and 15 (13%) were males. At 12 months postoperatively, there were statistically significant improvements (p < 0.001) from baseline for the mean VAS for pain (70.99 to 35.34), EQ-5D (0.52 to 0.75), ODI (31.84 to 18.00), and SF-36 PCS (38.17 to 44.74). A total of 78 patients (70%) were satisfied with the outcome of treatment. Conclusion Patients with persistent coccydynia and coccygeal instability resistant to nonoperative treatment may benefit from coccygectomy. Cite this article: Bone Joint J 2021;103-B(3):542–546.

ObjectiveTo assess the validity and clinical utility of the Brief Illness Perception Questionnaire (BIPQ) to measure illness perceptions in multiple forms of vasculitis.MethodsPatients with giant cell arteritis (GCA), Takayasu arteritis (TA), antineutrophil cytoplasmic antibody–associated vasculitis (AAV), and relapsing polychondritis (RP) were recruited into a prospective, observational cohort. Patients independently completed the BIPQ, Multidimensional Fatigue Inventory (MFI), Medical Outcomes Study 36-item Short Form survey (SF-36), and a patient global assessment (PtGA) at successive study visits. Physicians concurrently completed a physician global assessment (PGA) form. Illness perceptions, as assessed by the BIPQ, were compared to responses from the full-length Revised Illness Perception Questionnaire (IPQ-R) and to other clinical outcome measures.ResultsThere were 196 patients (GCA = 47, TA = 47, RP = 56, AAV = 46) evaluated over 454 visits. Illness perception scores in each domain were comparable between the BIPQ and IPQ-R (3.28 vs 3.47, P = 0.22). Illness perceptions differed by type of vasculitis, with the highest perceived psychological burden of disease in RP. The BIPQ was significantly associated with all other patient-reported outcome measures (rho = |0.50–0.70|, P < 0.0001), but did not correlate with PGA (rho = 0.13, P = 0.13). A change in the BIPQ composite score of ≥ 7 over successive visits was associated with concomitant change in the PtGA. Change in the MFI and BIPQ scores significantly correlated over time (rho = 0.38, P = 0.0008).ConclusionThe BIPQ is an accurate and valid assessment tool to measure and monitor illness perceptions in patients with vasculitis. Use of the BIPQ as an outcome measure in clinical trials may provide complementary information to physician-based assessments.

Background:Significant improvements in pain and other patient-reported outcomes (PROs) have been shown in large clinical trials in patients with rheumatoid arthritis (RA) who receive tocilizumab (TCZ) compared with placebo (PBO). Recent data suggest that pain in RA may be noninflammatory as well as inflammatory, and improvement in pain scores and other PROs may be seen in patients who do not respond to treatment based on disease activity measures that evaluate inflammation.Objectives:To assess changes in pain scores and other PROs in patients with RA who did or did not achieve ≥ 20% improvement in SJC in TCZ clinical trials.Methods:Data from patients with active RA who received intravenous TCZ 8 mg/kg + MTX or PBO + MTX in 3 Phase III studies (OPTION [NCT00106548], TOWARD [NCT00106574] and LITHE [NCT00109408]) were included. All patients had moderate to severe RA with an inadequate response or intolerance of MTX (OPTION, LITHE) or conventional synthetic disease-modifying antirheumatic drugs (csDMARDs; TOWARD). Changes in pain (visual analog scale [VAS], 0-100 mm), Health Assessment Questionnaire Disability Index (HAQ-DI, 0-3), 36-Item Short Form Survey (SF-36) physical component score (PCS) and mental component score (MCS; 0-50) and Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue score (0-52) from baseline to Week 24 were evaluated. Results were compared between patients receiving TCZ + MTX and those receiving PBO + MTX in both patients who achieved ≥ 20% improvement in SJC (responders) and those who did not (nonresponders). The changes from baseline were analyzed using a mixed model with repeated measures, including the following covariates and interactions: treatment, visit, baseline of endpoint, region, baseline DAS28 and interactions of visit with treatment and baseline of endpoint.Results:Data from 1254 responders (TCZ + MTX, n = 831; PBO + MTX, n = 423) and 620 nonresponders (TCZ + MTX, n = 225; PBO + MTX, n = 395) were included. Patients receiving TCZ + MTX had significantly greater improvement in pain scores and HAQ-DI compared with PBO + MTX in the responder group (–27.19 vs –16.77 and –0.55 vs –0.34, respectively;P< 0.0001 for both) and nonresponder group (–9.59 vs 2.53 and –0.20 vs 0.01;P< 0.0001 for both) at Week 24 (Figure 1). Similar results were seen at Week 16 in the nonresponder group (–11.06 vs –2.38 and –0.23 vs –0.04;P< 0.0001 for both) prior to initiation of rescue treatment. At Week 24 in the responder group, patients receiving TCZ + MTX had significantly greater improvements compared with PBO + MTX in SF-36 PCS and MCS (9.16 vs 5.71 and 6.55 vs 3.79, respectively;P< 0.0001 for both) (Figure 2) and FACIT-Fatigue (8.39 vs 5.11;P< 0.0001). In the nonresponder group, patients receiving TCZ + MTX had significantly greater improvements compared with PBO + MTX in SF-36 PCS at Week 16 (3.81 vs 1.65;P= 0.0006) and Week 24 (4.42 vs 1.01;P< 0.0001) (Figure 2) and FACIT-Fatigue at Week 16 (3.82 vs 1.32;P= 0.0039) and Week 24 (3.90 vs 1.40;P= 0.0111).Conclusion:Patients with RA who received TCZ + MTX had significantly greater improvements in pain score and other PROs than those who received PBO + MTX regardless of whether they achieved ≥ 20% improvement in SJC. Clinical outcome at Week 24 correlated well with PROs, with a relatively larger improvement in pain score and other PROs in the responder group than in the nonresponder group; relative to PBO + MTX, these improvements appear numerically similar in the responder and nonresponder groups with consistently smaller difference between the groups in TCZ-treated arms. The consistent effect of TCZ on PROs in both responder and nonresponder groups warrants further study on the impact of TCZ on sources of pain independent of that caused by joint inflammation.Figure:Acknowledgments:This study was sponsored by Genentech, Inc.

Background:The patient-reported outcomes are important components of quantitative methods of rheumatoid arthritis (RA) activity assessment which are used to choose the appropriate drug therapy. The value of these parameters can be significantly affected not only by the inflammatory process, but also by the psychological characteristics of the patient and, in particular, by hardiness [1].Objectives:To study the relationship between psychological factors and signs of RA activity.Methods:Patients with RA who met the EULAR/ACR 2010 criteria, and observed at the V. A. Nasonova Research Institute of Rheumatology were included. Clinical examination was performed including patient global assessment (PGA), physician global assessment (PhGA), pain measurement on a visual analog scale, tender joint count (TJC), swollen joint count (SJC). The functional status was determined by HAQ, the quality of life – by SF-36 EQ-5D, the nature of pain – by painDETECT, the presence of anxiety and depression – by HADS. Patients also completed Hardiness Survey questionnaire to assess hardiness (HDS) and 3 components of the HDS – commitment (CMT), control (CT) and challenge (CLN). Disease activity was evaluated with DAS28, CDAI, and RAPID3. All patients signed informed consent to participate in the study. Analysis of the data was performed using Spearman’s rank test, Fisher exact test, qui-square and t-tests.Results:85 patients with RA were included. There were 69 women and 16 men. Mean age was 56.7±13.1 years, disease duration – 7.6±2.7 years. 72 patients were positive for rheumatoid factor, 75 – for anti-cyclic citrullinated peptide antibody. CDAI showed high activity in 15, moderate – in 37, low – in 30, and remission in 3 patients, DAS 28 – in 10, 55, 12, and 8, and RAPID3 – in 24, 25, 15, and 21, respectively. 24 patients had subclinically or clinically expressed anxiety and 15 –subclinically or clinically expressed depression (≥8 according to HADS). In 31 patients, the painDETECT questionnaire revealed possible or probable neuropathic pain. Mean HDS was 84.8±21.7, CMT – 38.9±9.2, CT – 29.4±8.6, CLN – 17.3±7.1. These values were comparable with the corresponding population data for this age group. There was a significant inverse correlation between HDS and RA activity measures, including SJC, TJC, DAS28 (p<0.05), pain, PGA, PhGA, CDAI, RAPID3, and HAQ (p<0.01). In addition, HDS and all its components positively correlated with quality of life, assessed by SF-36 and EQ-5D (p<0.01). In patients with subclinically and clinically expressed anxiety and depression, HDS, CMT, and CT were significantly lower than in patients without anxiety and depression (p<0.01), while the values of CLN in these groups did not differ significantly.Conclusion:The results of the present study suggest that low HDS may be one of the significant factors determining RA activity level because it does not allow patients to adapt adequately to a stressful situation produced by the disease.References:[1]Maddi SR.

Background: Pulmonary hypertension (PH) is a chronic disease with a notable health burden; regular exercise may improve specific health outcome measures. Objective: The objective of this meta-analysis was to estimate the effectiveness of exercise training for PH patients. Data sources: PubMed, CINAHL, SportDiscuss and Google Scholar databases and reference lists of included studies were searched. Study selection: The selection criteria were randomized controlled trials (RCTs) employing an exercise training intervention. Data were extracted from the entered studies for analysis. The primary outcomes were peak oxygen uptake (VO2peak), anaerobic threshold (AT), 6-minute walk distance (6-MWD), and quality of life (QoL) measures (physical component score and mental component score). The analysis included 9 articles with a total of 302 participants: intervention (n = 154), and control (n = 148). Results: In the pooled analysis, improvements were seen in: VO2peak, mean difference (MD) 2.79 ml/kg/min (95% CI 2.00 to 3.59, p < 0.00001); AT, MD 107.83 ml/min (95% CI 39.64 to 176.00, p = 0.002); and 6-MWD, MD 46.67 meters (95% CI 32.39 to 60.96, p < 0.00001). Differences were found in the SF-36 physical component score MD 3.57 (95% CI 2.04 to 5.10, p < 0.00001) and the SF-36 mental component score MD 3.92 (95% CI 1.92 to 5.91, p = 0.001). Conclusion: This meta-analysis demonstrates exercise training has a beneficial effect on fitness, walking performance, and self-reported QoL in PH patients.

Abstract BackgroundThe translated and culturally adapted German version of the Veterans Rand 36 Items Health Survey (VR-36), and its short form, the VR-12 counterpart, were validated in a German sample of orthopedic (n = 399) and psychosomatic (n = 292) inpatient rehabilitation patients.MethodsThe instruments were analyzed regarding their acceptance, distributional properties, validity, responsiveness and ability to discriminate between groups by age, sex and clinically specific groups. Eligible study participants completed the VR-36 (n = 169) and the VR-12 (n = 177). They also completed validated patient-reported outcome measures (PROs) including the Euroqol-5 Dimensions 5 Level (EQ-5D-5L); Depression, Anxiety and Stress Scale (DASS); Hannover Functional Abilities Questionnaire (HFAQ); and CDC Healthy Days. The VR-12 and the VR-36 were compared to the reference instruments MOS Short Form-12 Items Health Survey (SF-12) version 1.0 and MOS Short Form-36 Items Health Survey (SF-36) version 1.0, using percent of completed items, distributional properties, correlation patterns, distribution measures of known groups validity, confirmatory factor analysis (CFA) and effect size measures.ResultsItem non-response varied between 1.8%/1.1% (SFVR−36/RESF−36) and 6.5%/8.6% (GHVR−36/GHSF−36). PCS was normally distributed (Kolmogorov-Smirnov Tests: p > 0.05) with means, standard deviations and ranges very similar between SF-36 (37.5 ± 11.7[13.8–66.1]) and VR-36 (38.5 ± 10.1[11.7–67.8]), SF-12 (36.9 ± 10.9[15.5–61.6]) and VR-12 (36.2 ± 11.5[12.7–59.3]). MCS was not normally distributed with slightly differing means and ranges between the instruments (MCSVR−36: 36.2 ± 14.2[12.9–66.6], MCSSF−36: 39.0 ± 15.6[2.0-73.2], MCSVR−12: 37.2 ± 13.8[8.4–70.2], MCSSF−12: 39.0 ± 12.3[17.6–65.4]). Construct validity was established by comparing correlation patterns of the MCSVR and PCSVR with measures of physical and mental health. For both PCSVR and MCSVR there were moderate (0.4–0.7) to high (> 0.7) correlations with convergent (PCSVR: 0.55–0.76, MCSVR: 0.60–0.78) and small correlations (< 0.3) with divergence (PCSVR: <0.12, MCSVR: <0.16) self-report measures. Known-groups validity was demonstrated for both VR-12 and VR-36 (MCS and PCS) via comparisons of distribution parameters with significant higher mean PCS and MCS scores in both VR instruments found in younger patients with fewer sick days in the last year and a shorter duration of rehabilitation.ConclusionsThe psychometric analysis confirmed that the German VR is a valid and reliable instrument for use in orthopedic and psychosomatic rehabilitation. Yet further research is needed to evaluate its usefulness in other populations.

Background: The minimally invasive chevron-Akin (MICA) osteotomy is an increasingly popular technique for the correction of hallux valgus. However, there is a paucity of literature comparing it with traditional open techniques. The purpose of this study was to compare the clinical and radiological outcomes of the MICA osteotomy using a new-generation MICA screw and scarf-Akin osteotomy for hallux valgus correction. Methods: Thirty cases of MICA osteotomy were propensity score matched 1:1 with a control group of 30 scarf-Akin osteotomy cases. The groups were matched for age, sex, body mass index, preoperative visual analog scale (VAS) score, American Orthopaedic Foot & Ankle Society (AOFAS) metatarsophalangeal-interphalangeal (MTP-IP) score, 36-Item Short-Form Health Survey (SF-36) physical component score (PCS) and mental component score (MCS), preoperative hallux valgus angle (HVA) and intermetatarsal angle (IMA), and concomitant procedures. Outcomes were compared at 6 and 24 months postoperatively. Early postoperative VAS scores were also compared. Results: Both groups demonstrated significant improvements in VAS score, AOFAS score, and SF-36 PCS and MCS at 6 and 24 months postoperatively. For the MICA group, HVA improved from 23.5 to 7.7 degrees, and IMA improved from 13.5 to 7.5 degrees. For the scarf-Akin osteotomy group, HVA improved from 23.7 to 9.3 degrees, and IMA improved from 13.6 to 7.8 degrees. The first 24-hour postoperative VAS score was significantly lower in the MICA group compared with the scarf-Akin group (2.0 ± 2.0 vs 3.4 ± 2.6, P = .029). However, there was no significant difference in clinical or radiological outcomes between the groups at 6 and 24 months. Conclusion: The MICA procedure with the new-generation MICA screw is an attractive option for the correction of hallux valgus, yielding similar midterm radiological and clinical outcomes compared with the well-established scarf-Akin osteotomy. The first 24-hour postoperative VAS score in the MICA group was also statistically lower, although its clinical significance remains to be determined. Level of Evidence: Level III, retrospective comparative study.

Category: Other; Ankle Introduction/Purpose: Insertional Achilles tendinitis (IAT) is a common cause of chronic posterior heel pain. Non-operative treatment has demonstrated evidence of success, with similar failure rates in both the young and the elderly. Surgical management can reproducibly improve patients’ pain and functional status. Older patients are considered to be at a higher risk for surgical complications due to associated comorbidities when compared to patients under the age of 60. The aim of this study is to investigate the impact of comorbidities and peri-operative variables on functional patient reported outcomes following surgical treatment of IAT in those over and under the age of 60. Methods: Retrospective review of prospectively collected data pertaining to a consecutive series of adult patients who underwent surgical management of IAT by a single surgeon (J.B.). Patients were separated into those 60 years of age and younger, and those above 60. Patients undergoing concomitant surgical procedures or revisions were excluded. Patient demographics, co- morbidities, perioperative variables, and post-operative complications were collected. Visual Analogue Scale (VAS), Short Form Health Survey Physical Component Score (SF-36 PCS), wound infection, and recurrence were assessed with a minimum follow-up of 12 months. Statistics were obtained using linear regression mixed models, and chi-squared analysis. Results: 38 operative cases were identified including 17 patients over and 21 patients under 60 years of age (mean 66.8 +/- 5.1yrs, 49.1 +/- 8.4yrs, respectively). There were no significant differences in demographics, rates of co-morbidities, or post-operative infection between the two groups. Both young and elderly groups experienced improvements in mean VAS pain scores at 6 months (3.3 and 2.7, respectively, P = 0.416) and 12 months (5.0 and 4.1, respectively, P = 0.322) post-operatively. SF-36 PCS improvements were also observed in both young and elderly cohorts at 6 (mean 22.1 and 9.3, respectively, P = 0.122) and 12 months (mean 30.4 and 20.4, respectively, P = 0.158). Linear regression analysis showed no statistical difference between the presence of co-morbidities, or age, on clinical outcomes. Conclusion: None of the co-morbidities nor peri-operative variables assessed were linked to increased risk of failed surgical correction of IAT in elderly patients, suggesting surgical correction of IAT in geriatric populations is an appropriate and reproducible treatment option. Further higher-powered studies, with longer follow-up times would be of use to better elucidate the influence of co-morbidities on recurrence.

Background: Patients experience varying degrees of pain and symptoms during the early recovery period after hip arthroscopy for femoroacetabular impingement (FAI). Some “fast starters” report minimal discomfort and are eager to advance activities, while “slow starters” describe severe pain and limitations. The relationship between these early postoperative symptoms and 2-year outcomes after hip arthroscopy is unknown. Purpose: To analyze the relationship between early postoperative pain and 2-year patient-reported outcomes (PROs) after hip arthroscopy for FAI. Study Design: Cohort study; Level of evidence, 2. Methods: Patients without arthritis or dysplasia who were undergoing primary hip arthroscopy for FAI were prospectively enrolled and completed validated PROs. Scores for visual analog scale (VAS) for pain were collected preoperatively and at 1 week, 6 weeks, and 2 years postoperatively. Scores for the modified Harris Hip Score (mHHS), Hip disability and Osteoarthritis Outcome Score (HOOS), and 12-Item Short Form Health Survey (SF-12) were collected preoperatively and 2 years postoperatively. Paired t tests were used to evaluate PRO score changes, and correlation analyses were used to assess relationships between early postoperative pain and 2-year postoperative outcomes. Results: A total of 166 patients were included (55% female; mean ± SD age, 35.29 ± 9.6 years; mean body mass index, 25.07 ± 3.98 kg/m2). Patients demonstrated significant improvements in PRO scores (VAS, SF-12 Physical Component Score, mHHS, and all HOOS subscales) at 2 years after hip arthroscopy for FAI ( P < .001). There was a significant correlation between lower 1-week VAS pain level (fast starters) and lower 2-year VAS pain level ( R = 0.31; P < .001) as well as higher 2-year PRO scores (SF-12 Physical Component Score, mHHS, and all HOOS subscales: R = −0.21 to −0.3; P < .001). There was no correlation between 1-week VAS pain and 2-year SF-12 Mental Component Score ( P = .17). Preoperative VAS pain levels showed positive correlations with 1-week postoperative pain scores ( R = 0.39; P < .001) and negative correlations with 2-year patient outcomes ( R = −0.15 to −0.33, P < .01). There was no correlation between 6-week postoperative pain scores and 2-year PRO scores. Conclusion: Fast starters after hip arthroscopy for FAI experience sustained improvements in outcomes at 2 years after surgery. Patient pain levels before surgery may delineate potential fast starters and slow starters.

Aims Thresholds for operative eligibility based on body mass index (BMI) alone may restrict patient access to the benefits of arthroplasty. The purpose of this study was to evaluate the relationship between BMI and improvements in patient-reported outcome measures (PROMs), and to determine how many patients would have been denied improvements in PROMs if BMI cut-offs were to be implemented. Methods A prospective cohort of 3,449 primary total hip arthroplasties (THAs) performed between 2015 and 2018 were analyzed. The following one-year PROMs were evaluated: hip injury and osteoarthritis outcome score (HOOS) pain, HOOS Physical Function Shortform (PS), University of California, Los Angeles (UCLA) activity, Veterans Rand-12 Physical Component Score (VR-12 PCS), and VR-12 Mental Component Score (VR-12 MCS). Positive predictive values for failure to improve and the number of patients denied surgery in order to avoid a failed improvement were calculated for each PROM at different BMI cut-offs. Results There was a trend to improved outcomes in terms of pain and function improvements with higher BMI. Patients with BMI ≥ 40 kg/m2 had median (Q1, Q3) HOOS pain improvements of 58 points (interquartile range (IQR) 41 to 70) and those with BMI 35 to 40 kg/m2 had median improvements of 55 (IQR 40 to 68). With a BMI cut-off of 30 kg/m2, 21 patients would have been denied a meaningful improvement in HOOS pain score in order to avoid one failed improvement. At a 35 kg/m2 cut-off, 18 patients would be denied improvement, at a 40 kg/m2 cut-off 21 patients would be denied improvement, and at a 45 kg/m2 cut-off 21 patients would be denied improvement. Similar findings were observed for HOOS-PS, UCLA, and VR-12 scores. Conclusion Patients with higher BMIs show greater improvements in PROMs. Using BMI alone to determine eligibility criteria did not improve the rate of clinically meaningful improvements. BMI thresholds prevent patients who may benefit the most from surgery from undergoing THA. Surgeons should consider PROMs improvements in determining eligibility for THA while balancing traditional metrics of preoperative risk stratification.
