Misconceptions and the Acceptance of Evidence-based Nonsurgical Interventions for Knee Osteoarthritis. A Qualitative Study

'The right advice': a qualitative study examining enablers and barriers to recreational running and beliefs about knee health following knee surgery

OBJECTIVES

To examine the experiences, knowledge and beliefs of recreational runners with a history of knee surgery regarding (i) enablers and barriers to running participation, (ii) the association of running and knee joint health, and (iii) perceived benefits and motivations for running.

METHODS

17 runners (≥3 times/week, ≥10 km/week) with a history of knee surgery (7±7 years post-surgery, 9 women, age 36±8 years) participated in one-on-one semi-structured interviews. Interviews were recorded, transcribed verbatim and analysed using reflexive thematic analysis. Trustworthiness was built by following established qualitative research guidelines and by participant validation of findings in the final analysis stages.

RESULTS

We identified 9 themes (5 subthemes) for aim (i); 3 themes (10 subthemes) for aim (ii); and 2 themes (4 subthemes) for aim (iii). Positive health professional support including education, exercise rehabilitation and a tailored return-to-run plan enabled participants to return to running following surgery. Effective load management either independently or with coach assistance, and consistent strength training were considered key to maintaining participation. Barriers to running following surgery included unhelpful health professional encounters, persistent knee symptoms and muscle weakness, new running-related injuries, anxiety and fear about reinjury, and difficulty finding time. Participants had varying beliefs about running and knee joint health, although most believed that running benefited long-term knee health. Improved mental health and social connection were the most common motivators to run.

CONCLUSION

Our qualitative findings may inform strategies to support adults to commence, or return to, and maintain running participation following knee surgery.

Effects of X-ray-based diagnosis and explanation of knee osteoarthritis on patient beliefs about osteoarthritis management: A randomised clinical trial

BACKGROUND

Although X-rays are not recommended for routine diagnosis of osteoarthritis (OA), clinicians and patients often use or expect X-rays. We evaluated whether: (i) a radiographic diagnosis and explanation of knee OA influences patient beliefs about management, compared to a clinical diagnosis and explanation that does not involve X-rays; and (ii) showing the patient their X-ray images when explaining radiographic report findings influences beliefs, compared to not showing X-ray images.

METHODS AND FINDINGS

This was a 3-arm randomised controlled trial conducted between May 23, 2024 and May 28, 2024 as a single exposure (no follow-up) online survey. A total of 617 people aged ≥45 years, with and without chronic knee pain, were recruited from the Australian-wide community. Participants were presented with a hypothetical scenario where their knee was painful for 6 months and they had made an appointment with a general practitioner (primary care physician). Participants were randomly allocated to one of 3 groups where they watched a 2-min video of the general practitioner providing them with either: (i) clinical explanation of knee OA (no X-rays); (ii) radiographic explanation (not showing X-ray images); or (iii) radiographic explanation (showing X-ray images). Primary comparisons were: (i) clinical explanation (no X-rays) versus radiographic explanation (showing X-ray images); and (ii) radiographic explanation (not showing X-ray images) versus radiographic explanation (showing X-ray images). Primary outcomes were perceived (i) necessity of joint replacement surgery; and (ii) helpfulness of exercise and physical activity, both measured on 11-point numeric rating scales (NRS) ranging 0 to 10. Compared to clinical explanation (no X-rays), those who received radiographic explanation (showing X-ray images) believed surgery was more necessary (mean 3.3 [standard deviation: 2.7] versus 4.5 [2.7], respectively; mean difference 1.1 [Bonferroni-adjusted 95% confidence interval: 0.5, 1.8]), but there were no differences in beliefs about the helpfulness of exercise and physical activity (mean 7.9 [standard deviation: 1.9] versus 7.5 [2.2], respectively; mean difference -0.4 [Bonferroni-adjusted 95% confidence interval: -0.9, 0.1]). There were no differences in beliefs between radiographic explanation with and without showing X-ray images (for beliefs about necessity of surgery: mean 4.5 [standard deviation: 2.7] versus 3.9 [2.6], respectively; mean difference 0.5 [Bonferroni-adjusted 95% confidence interval: -0.1, 1.2]; for beliefs about helpfulness of exercise and physical activity: mean 7.5 [standard deviation: 2.2] versus 7.7 [2.0], respectively; mean difference -0.2 [Bonferroni-adjusted 95% confidence interval: -0.7, 0.3]). Limitations of our study included the fact that participants were responding to a hypothetical scenario, and so findings may not necessarily translate to real-world clinical situations, and that it is unclear whether effects would impact subsequent OA management behaviours.

CONCLUSIONS

An X-ray-based diagnosis and explanation of knee OA may have potentially undesirable effects on people's beliefs about management.

Voices from the clinic: a qualitative analysis of physiotherapy strategies in musculoskeletal care for knee osteoarthritis patients

BACKGROUND

Physiotherapy has emerged as an important health strategy to deliver lifestyle, exercise and physical activity for people with knee osteoarthritis. However, little is known about the extent to which physiotherapists adhere to clinical practice guidelines. This study aimed to explore the perspectives and care patterns of physiotherapists in Sydney, Australia on their delivery of knee osteoarthritis care and how this aligns with the 2019 Osteoarthritis Research Society International (OARSI) guidelines.

METHODS

We invited thirty-three physiotherapists from nine private practices in metropolitan Sydney to partake in a semi-structured interview. The interviews were digitally recorded and transcribed verbatim. The data collected were analysed deductively using content analysis, comparing guidelines to current care patterns, while their perspectives were inductively analysed through thematic analysis.

RESULTS

Thirty physiotherapists participated (age range 22-63 years, 17 male and 13 female). Interview responses indicated that most physiotherapists were satisfied with their care of knee osteoarthritis patients. Most physiotherapists delivered "core" guideline-based care of education and land-based exercise. Recommendations of modalities of exercise, including hydrotherapy and manual therapy, were discussed and were perceived to be beneficial despite not being "core" clinical guideline recommendations. Current treatment strategies focussed on disease severity, symptom presentation and/or patient exercise history with little emphasis on education about osteoarthritis pathophysiology and drug-based pain relief. The thematic analysis identified two over-arching themes; (1) capacity to deliver and awareness of evidence-based care and (2) perceived recommendations for future physiotherapy management. Participants identified notable areas of potential service improvement including developing stronger and more effective reimbursement models, increased consult times and improved patient access.

CONCLUSION

The study provided unique insights towards physiotherapists' current usual knee osteoarthritis care and their perceived barriers to delivering guideline-based care. Thus, informing a need for future studies to focus on developing specific and detailed guidelines if physiotherapists are to align more closely to the core guideline-based recommendations.

TRIAL REGISTRATION

This study was part of a larger study, with the full protocol published and registered at ClinicalTrials (ACTRN12620000188932, ACTRN12620000218998) 19/02/2020).

Making sense of osteoarthritis: A narrative review

People make sense of osteoarthritis (OA) by drawing on information, beliefs, and knowledge. This narrative review summarises diverse qualitative and quantitative research investigating beliefs and knowledge about OA and the impact these have on behaviour and outcomes. It synthesises evidence and highlights key actions clinicians can take to support people to make sense of OA in helpful ways. Beliefs about OA inform the behaviour of those living with OA and the behaviour of clinicians caring for people with OA. Beliefs about OA often focus on joint degradation and inevitable progression. These impairment-focused fatalistic beliefs can result in reduced offer of, or engagement in, active management strategies. Alternative views focus on health as part of a dynamic ecosystem where people are healthy when they can participate in activities they value. These beliefs are associated with increased engagement in self-management and lifestyle-based interventions. Clinician actions that support people to make sense of OA ways that align with helpful behaviours and support participation in valued activities represent key opportunities to improve health and well-being.

General practitioners experience multi-level barriers to implementing recommended care for hip and knee osteoarthritis: a qualitative study

BACKGROUND

General practitioners (GPs) play a key role in managing osteoarthritis, including referring to appropriate management services. Physiotherapist-led osteoarthritis management programs and advanced practice triage services are effective, but GPs views on them are largely unknown. This study aimed to explore general practitioner perspectives on: (1) managing patients with hip and knee osteoarthritis, and (2) physiotherapy-led osteoarthritis care and referral pathways.

METHODS

Interview topic guides were developed based on the theoretical domains framework. Twenty-five semi-structured interviews with GPs were conducted. All data were coded independently by at least two researchers and analysed inductively using thematic analysis, with barrier themes mapped to the socioecological model.

RESULTS

Two interrelated themes were identified: (i) GPs had good general knowledge of recommended osteoarthritis care, but (ii) they faced multi-level challenges facilitating or directly providing evidence-based care. Nearly all GPs identified exercise as first-line care and surgery as a last resort. Most were aware imaging was not required to diagnose osteoarthritis, yet reported often referring for imaging. Many GPs expressed challenges facilitating patient engagement in physiotherapy due to patient, environmental/social and system level barriers. Key barriers included: perceived patient expectations and lack of motivation to attend physiotherapy, a lack of knowledge of available physiotherapy services, a lack of affordable physiotherapy services, and lengthy waiting times for public orthopaedic appointments. Having private health insurance was perceived as an enabler.

CONCLUSIONS

Despite having good knowledge of guideline-recommended care, GPs in our study experienced multi-level barriers to implementing this care in practice. Public health information and strategies to address patient's beliefs and lack of motivation to exercise may help reduce barriers to engaging in appropriate care. Urgent health system funding reforms are needed to allow GPs to appropriately manage patients with hip and knee osteoarthritis.

Physical activity and joint health: Implications for knee osteoarthritis disease pathophysiology and mechanics

Knee osteoarthritis is experienced by hundreds of millions of people worldwide and is a major cause of disability. Although enhancing physical activity levels and the participation in exercise programmes has been proved to improve the debilitating illness of osteoarthritis, many do not engage in recommended levels of physical activity. One of the reported barriers to exercise engagement is the perception that physical activity can damage joint health and is attributed to the incorrect perception of 'wear and tear'. We posit that these perceptions arise from uncertainty and ambiguity generated from conflicting research findings. In this review, we explore the complex relationship between knee osteoarthritis and physical activity. We demonstrate how factors contribute to the uncertainty around the effects of physical activity on joint tissue metabolism, structure and function. The aim of this review is to demonstrate how a nuanced approach to the relationship between physical activity and knee osteoarthritis can help to dispel misconceptions, leading to better management strategies and improved quality of life for patients.

"I Have Faith in God That I Will Get Better"-The Multidimensional Perceptions and Expectations of Patients With Chronic Shoulder Pain: A Qualitative Analysis of Common Sense

OBJECTIVE

This descriptive qualitative study aimed to gain insights into the expectations of individuals with chronic shoulder pain and to investigate how different levels of disability may influence their beliefs and expectations regarding improvement.

METHODS

This qualitative study utilized the Common Sense Model as its theoretical framework. Conducted within a public physical therapy clinic, individuals with chronic shoulder pain who were awaiting the initiation of the treatment were included. Participants, female and male (aged 30-69 years), were purposefully sampled. Thirty participants, categorized into 2 groups based on the Shoulder Pain and Disability Index (SPADI) scores, underwent semi-structured interviews. Group 1, lower SPADI scores (0-60), had 10 participants, and Group 2, higher SPADI scores (61-100), had 20 participants. Thematic analysis and inductive coding were employed to analyze the interviews.

RESULTS

Common themes emerged in both groups: the use of medical terms for understanding the diagnosis and the multidimensional impact of pain. The last 2 themes differed between groups. Notable differences included Group 1's focus on resources for pain relief and positive expectations with physical therapy, while Group 2 emphasized rest, religion as a resource for pain relief, and God's role in improvement.

CONCLUSION

These findings highlight the complexity of beliefs and expectations among patients with chronic shoulder pain. Individuals with greater disability often incorporated religious beliefs into their coping strategies, but they held lower recovery expectations and reported negative treatment experiences. These insights have implications for tailoring patient-centered care approaches.

IMPACT

This study underscores the need for health care providers to consider the multidimensionality of recovery expectations, which can significantly influence patient outcomes. Clinicians can reflect on this knowledge to optimize treatment strategies and improve patient prognosis.

Barriers and enablers to the management of osteoarthritis in primary care in Ireland from the perspective of healthcare professionals and individuals with osteoarthritis: a qualitative study using the Theoretical Domains Framework

OBJECTIVES

To explore the barriers and enablers to providing and receiving primary care for osteoarthritis (OA) in Ireland from the perspectives of primary care healthcare professionals (HCPs) and individuals with OA.

DESIGN

Descriptive qualitative study incorporating an inductive thematic analysis to identify key barrier and enabler themes and subsequent deductive mapping to the Theoretical Domains Framework (TDF).

SETTING

Primary care in Ireland.

PARTICIPANTS

HCPs, including 6 general practitioners, 5 physiotherapists, 1 occupational therapist and 1 practice nurse, and 13 individuals with OA were interviewed.

RESULTS

Identified barriers and enablers related to nine domains of the TDF. Key barriers identified by HCPs included limited and delayed access to multidisciplinary primary care services, lack of integrated care pathways specific to OA and insufficient training in musculoskeletal conditions including OA. Individuals with OA also reported poor access to health services due to long waiting lists, lack of education on OA and feelings of not being taken seriously by HCPs. There is a need for targeted HCP education and training to address the identified knowledge, skills and confidence gaps in communication, diagnosis and evidence-based management of OA. Improved management of OA through system-level changes, including integrated care pathways with multidisciplinary services to better support individuals with OA in the community, is required.

CONCLUSIONS

This study identified several barriers and enablers to the management of OA. These findings highlight areas to be targeted by future interventions aimed at improving the management of OA in primary care.

Translation, Cross-Culture Adaptation and Measurement Properties of the Simplified Chinese Version of the Osteoarthritis Knowledge Scale

OBJECTIVE

The aim of this study was to culturally adapt the Osteoarthritis Knowledge Scale (OAKS) into a simplified Chinese version and to evaluate its measurement properties among Chinese-speaking populations.

METHODS

The OAKS scale was translated and cross-culturally adapted following COSMIN guidelines. A total of 368 participants were recruited, including individuals with knee or hip osteoarthritis (OA), healthcare professionals, and individuals without OA. The study evaluated the scale's internal consistency, test-retest reliability, and factor structure using Exploratory Factor Analysis (EFA).

RESULTS

The translated OAKS scale demonstrated acceptable levels of reliability across different groups. Cronbach's alpha for the KOAKS was 0.70 overall, with subgroup values ranging from 0.70 to 0.71. For the HOAKS, Cronbach's alpha was 0.77 overall, with subgroup values ranging from 0.63 to 0.72. Test-retest reliability showed high Intraclass Correlation Coefficient (ICC) values for both scales (KOAKS: ICC = 0.960; HOAKS: ICC = 0.982). EFA revealed that the overall OAKS explained a substantial portion of the variance (60.51%), with KOAKS accounting for 59.35% and HOAKS accounting for 54.68% of the variance.

CONCLUSION

The simplified Chinese version of the OAKS is a reliable tool for assessing OA knowledge among Chinese-speaking patients, healthcare professionals, and the general public. The findings highlight the necessity for continuous improvement and adaptation of educational interventions to address specific knowledge gaps within the Chinese context.

Factors that impact the implementation of patient reported outcomes in routine clinical care for peripheral artery disease from the patient perspective

PURPOSE

Patient reported outcome measures (PROMs) are well-suited for the longitudinal assessment of quality of life, including depression and physical limitations associated with peripheral artery disease (PAD) that are not routinely assessed in clinical care. This study was designed to gain the patient perspective to facilitate implementation of PROMs into clinical practice for PAD management.

METHODS

Twenty-three patients with PAD at a single vascular surgery clinic were enrolled for a qualitative interview, July-December 2022. Patients completed PROMIS Physical Function and Depression assessments before undergoing semi-structured interviews. Two researchers used an inductive thematic analysis to analyze emergent themes from transcribed interviews.

RESULTS

The average age of participants was 69.5 ± 8.2 years; 91% were Caucasian, and 39% were female. Qualitative interviews revealed three implementation-related themes: (1) patient preferences on the timing and type of PROMs collected, (2) PROMs applications in outpatient PAD care, including discussions with their physician, and (3) the clinical value of PROMs. Overall, patients with PAD prefer PROMs related to quality of life and physical function over other domains. Patients appreciate the convenience to complete PROMs before their appointment. Patients would like to verbally discuss meaningful score changes with their providers without the use of graphical aids. Most patients believe PROMs are valuable in their clinical care if their physician reviews the results and the PROM questions apply to their disease symptoms.

CONCLUSIONS

Patient preferences inform future successful implementations and will improve patient completion rates for the collection and clinical use of PROMs in PAD clinical care.

Safety and Effectiveness of a Novel Liposomal Intra-Articular Lubricant in Symptomatic Knee Osteoarthritis: A First-in-Human Study

Background/Objectives: Osteoarthritis (OA) is a common disease that affects almost half the population at some point in their lives, causing pain and decreased functional capacity. New conservative treatment modalities are being proposed to provide symptomatic relief and delay surgical intervention. This study aimed at evaluating the safety of the novel liposomal boundary lubricant, injected intra-articularly in patients with moderate knee OA. Additionally, the effect on the functionality and life quality was assessed. Methods: Eighteen of the twenty screened subjects met inclusion criteria and were enrolled in the study. After receiving a single IA injection of AqueousJoint, patients were prospectively evaluated at baseline and at 2, 4, 8, 12, and 26 weeks. Numeric Pain Rating Scale (NRS), Knee injury and Osteoarthritis Outcome Score (KOOS), Short Form Health Survey (SF12) and range of motion were also recorded. Results: The final analysis was conducted on 18 subjects. No adverse events related to the investigational product were observed in the study. No serious adverse events were observed at all. A significant decrease in pain was demonstrated at all time points vs. baseline (Friedman X2 = 35.08, p < 0.001). Significant improvement was demonstrated in KOOS pain, symptoms, sports, and ADL subscales (p < 0.001). Conclusions: Despite a relatively small sample, it was demonstrated that single IA AqueousJoint injection is a safe procedure, resulting in significant pain reduction, higher ADL score, and higher KOOS sport scores. The effects lasted up to 6 months.

Communicative Practices Clinicians Use to Correct Patient Misconceptions in Primary Care Visits

To investigate how clinicians correct patient misconceptions, we analyzed 23 video recordings of primary care visits. Analysis focused on operationalizing, identifying, and characterizing clinician corrections, integrating two inductive approaches: microanalysis of clinical interaction and conversation analysis. According to our definition, patient misconception-clinician correction episodes met three essential criteria: (1) the clinician refuted something the patient had said, (2) which the patient had presented without uncertainty, and (3) which contained a proposition that was factually incorrect. We identified 59 such episodes; the patient misconceptions most commonly related to medication issues; fewer than half had foreseeable implications for patients' future actions. We identified seven clinician correction practices: Three direct practices (displaying surprise, marking disagreement, contradicting the patient) and four indirect practices (presenting the correct proposition, providing explanations, invoking an outside authority, demonstrating with evidence). We found an almost equal distribution of these direct and indirect practices.

I am in Charge, But Not Always in Control: A Qualitative Exploration of Female's Beliefs and Knowledge About Their Pelvic Pain

OBJECTIVES

Beliefs and knowledge about pain can influence how an individual approaches pain management. At present, there have been no investigations into the beliefs and knowledge that females hold about their pelvic pain; therefore, pain intervention approaches may not be targeted at current patient understandings. Exploring beliefs and knowledge may help inform and subsequently improve pain intervention outcomes for pelvic pain by allowing more tailored content to be delivered. This study aimed to identify beliefs and knowledge that females hold about their pelvic pain.

MATERIALS AND METHODS

Semistructured interviews (n = 12) were conducted. Based on the common sense model, interview questions investigated participants' beliefs and knowledge related to the identity (diagnostic labels), cause, consequence, control, and timeline of their pelvic pain. Transcribed interviews were analyzed using an Interpretive Description Framework.

RESULTS

Participants reported holding biopsychosocial understandings of pain; however, many described their own pain experience in a way that was more aligned with the biomedical model of pain, suggesting incongruence in pain understanding. Participants valued their ability to take charge of their pain management, highlighting bodily autonomy and being proactive in pain management approaches. This approach to management did not provide total control over participants' pelvic pain. Pelvic pain was perceived as disruptive of life, both at present and into the future, with the predictability of pain varying over time.

CONCLUSION

This study provides insight into the perspectives of females with pelvic pain. Recommendations for clinicians are provided with a focus on delivering targeted education and equipping patients with helpful representations of their pain.

Building the OAChangeMap to Improve the Service Delivery of the New South Wales Osteoarthritis Chronic Care Program: A Worked Example of Using a Codesign Framework

OBJECTIVE

The Osteoarthritis Chronic Care Program (OACCP) has been implemented in Australian public hospitals to deliver best evidence osteoarthritis (OA) care. It is important to ensure that the OACCP continues to deliver evidence-based OA care as intended. We aimed to identify barriers and enablers to delivering the OACCP, prioritize the barriers, and generate strategies to address them.

METHODS

This study provides a worked example of a seven-step theory-informed codesign framework. We invited OACCP coordinators to participate in semistructured interviews (analyzed thematically) and complete a questionnaire to identify barriers and enablers to delivery of the OACCP. We then invited a broader group of stakeholders (OACCP coordinators, health managers, policy makers, consumers, and researchers) to prioritize the barriers via a short survey (survey 2). We held five codesign workshops in which we mapped the priority barriers to the Theoretical Domains Framework and developed strategies to address them.

RESULTS

Sixteen coordinators were interviewed, and the main barriers identified were as follows: (1) patients often have beliefs that are inconsistent with best evidence care, (2) there are aspects of clinical care that are not delivered optimally, and (3) system-level factors are a barrier to optimal patient care and sustainability of the OACCP. We codesigned a plan for action with patient educational materials, shared decision-making tools, and health professional education and training.

CONCLUSION

Our worked example of codesign used a theory-based, data-driven approach with key stakeholders, identified and prioritized barriers to the delivery of the OACCP, acknowledged enablers, and generated a plan for feasible strategies to improve the program.

A randomized clinical trial testing digital mindset intervention for knee osteoarthritis pain and activity improvement

This randomized clinical trial evaluated the effectiveness of short, digital interventions in improving physical activity and pain for individuals with knee osteoarthritis. We compared a digital mindset intervention, focusing on adaptive mindsets (e.g., osteoarthritis is manageable), to a digital education intervention and a no-intervention group. 408 participants with knee osteoarthritis completed the study online in the US. The mindset intervention significantly improved mindsets compared to both other groups (P < 0.001) and increased physical activity levels more than the no-intervention group (mean = 28.6 points, P = 0.001), but pain reduction was not significant. The mindset group also showed significantly greater improvements in the perceived need for surgery, self-imposed physical limitations, fear of movement, and self-efficacy than the no-intervention and education groups. This trial demonstrates the effectiveness of brief digital interventions in educating about osteoarthritis and further highlights the additional benefits of improving mindsets to transform patients' approach to disease management. The study was prospectively registered (ClinicalTrials.gov: NCT05698368, 2023-01-26).

Explain Breathlessness: Could 'Usual' Explanations Contribute to Maladaptive Beliefs of People Living with Breathlessness?

BACKGROUND

Explanations provided by healthcare professionals contribute to patient beliefs. Little is known about how healthcare professionals explain chronic breathlessness to people living with this adverse sensation.

METHODS

A purpose-designed survey disseminated via newsletters of Australian professional associations (physiotherapy, respiratory medicine, palliative care). Respondents provided free-text responses for their usual explanation and concepts important to include, avoid, or perceived as difficult to understand by recipients. Content analysis coded free text into mutually exclusive categories with the proportion of respondents in each category reported.

RESULTS

Respondents (n = 61) were predominantly clinicians (93%) who frequently (80% daily/weekly) conversed with patients about breathlessness. Frequent phrases included within usual explanations reflected breathlessness resulting from medical conditions (70% of respondents) and physiological mechanisms (44%) with foci ranging from multifactorial to single-mechanism origins. Management principles were important to include and phrases encouraging maladaptive beliefs were important to avoid. The most frequent difficult concept identified concerned inconsistent relationships between oxygenation and breathlessness. Where explanations included the term 'oxygen', a form of cognitive shortcut (heuristic) may contribute to erroneous beliefs.

CONCLUSIONS

This study presents examples of health professional explanations for chronic breathlessness as a starting point for considering whether and how explanations could contribute to adaptive or maladaptive breathlessness beliefs of recipients.

Determining Appropriateness of Total Joint Arthroplasty for Hip and Knee Osteoarthritis: A Patient-Centred Conceptual Model

INTRODUCTION

Total joint arthroplasty (TJA) for osteoarthritis is one of several treatment options with benefits and harms that patients value differently. However, the process for determining TJA appropriateness does not sufficiently acknowledge patient perspectives. The aim of this paper is to propose an evidence-informed patient-centred conceptual model for elective TJA appropriateness for hip and knee osteoarthritis.

METHODS

Our interprofessional team developed a conceptual model for determining the appropriateness of adults considering elective TJA. The model was informed by a review of the evidence, a qualitative study we conducted with adults who underwent TJA for osteoarthritis to determine barriers and facilitators to the use of appropriateness criteria, and the research and clinical experience of team members.

RESULTS

Appropriateness is providing health services (e.g., TJA) with net benefits to the right patient at the right time. The proposed Patient-centred Elective TJA Appropriateness Conceptual Model involves three key steps. First, assess adults with osteoarthritis to determine eligibility for TJA. Second, acknowledge the patient's informed preferences including their expectations and goals. Third, explore and support their mental and physical readiness for TJA. Given that osteoarthritis is a chronic condition, these steps can be revisited over time with patients.

DISCUSSION AND CONCLUSION

Our proposed conceptual model reconceptualises the appropriateness of TJA to be more patient-centred. Hence, this approach has the potential to be a more inclusive approach and ensure patients undergoing TJA are eligible, ready to proceed, and achieve what matters most to them. Future research is needed to test and validate the model.

Do Maladaptive Imaging Beliefs Predict Self-Reported Pain Interference and Physical Function in Patients With Musculoskeletal Disorders?

OBJECTIVE: To determine if maladaptive imaging beliefs correlated with, and predicted pain interference and physical function outcomes in people with musculoskeletal pain disorders. DESIGN: A prospective cohort study of patients with musculoskeletal disorders receiving outpatient physical therapy from April 2022 to August 2023. METHODS: Four questions about imaging were asked to assess maladaptive beliefs, the need to rule out serious conditions, guide treatment, determine diagnosis, and validate symptoms. Correlations with beliefs and outcomes were assessed using Kendall's tau rank and Spearman's rho correlation coefficients. Generalized linear models determined if these beliefs predicted outcomes at baseline and 6 weeks. RESULTS: The cohort included 152 participants (mean [standard deviation] age: 56.13 [15.13]; 32.2% male). Maladaptive imaging beliefs correlated positively with pain interference and negatively with physical function. The need to rule out serious conditions and validate symptoms correlated with pain interference (range: τb = 0.17, 0.20; P = .003, .0121) and physical function (range: ρ = -0.22, -0.22; P = .006, .008). All but 1 belief correlated with pain interference (range: τb = 0.19, 0.24; P<.001, .004) and physical function (range: ρ = -0.26, -0.21; P = .001, .009) at 6 weeks. Each additional belief slightly increased pain interference at 6 weeks (β = 0.01; 95% CI: 0.001, 0.03; P = .04) and lowered physical function at both baseline (β = -0.97; 95% CI: -1.66, -0.28; P = .01) and 6 weeks (β = -0.76; 95% CI: -1.37, -0.15; P = .02). CONCLUSION: Maladaptive imaging beliefs were significantly (albeit weakly) correlated with pain and physical function. Each additional maladaptive imaging belief increased pain interference at 6 weeks and lowered physical function at baseline and 6 weeks. Beliefs about the necessity of imaging to properly manage musculoskeletal disorders may influence outcomes. J Orthop Sports Phys Ther 2024;54(9):1-10. Epub 5 July 2024. doi:10.2519/jospt.2024.12625.

Translation and Cross-Cultural Adaptation of the Osteoarthritis Knowledge Scale Into Turkish

BACKGROUND

The Osteoarthritis Knowledge Scale (OAKS) is a validated tool for assessing knowledge about hip and knee osteoarthritis (OA). However, to date, there has been no translation and adaptation of the OAKS for the Turkish population.

OBJECTIVES

To translate and cross-culturally adapt the OAKS into Turkish and to assess its psychometric properties in the Turkish population with and without hip or knee OA.

METHODS

The OAKS was translated following accepted guidelines. A validation study assessed internal consistency, test-retest reliability and measurement error. An exploratory factor analysis was conducted to assess the factor structure.

RESULTS

A total of 278 participants (n = 70 with hip OA, n = 105 with knee OA, and n = 103 without OA) were included. Internal consistency was 0.72, 0.79 and 0.79 for participants with hip OA, knee OA, and no OA, respectively. The test-retest intraclass correlation coefficient was 0.72 (95% CI; 0.45-0.85), 0.89 (95% CI; 0.82-0.93) and 0.88 (95% CI; 0.79-0.93) for participants with hip OA, knee OA and no OA, respectively. It had three principal components accounting for 57.2% of the total variance.

CONCLUSIONS

The Turkish version of the OAKS is a reliable and valid tool for measuring OA knowledge in the Turkish population, including those with and without hip and knee OA. Test-retest reliability was below acceptable levels in the population with hip OA only. Therefore, we recommend that the ICC be interpreted with caution when used in this population.

People with painful knee osteoarthritis hold negative implicit attitudes towards activity

ABSTRACT

Negative attitudes/beliefs surrounding osteoarthritis, pain, and activity contribute to reduced physical activity in people with knee osteoarthritis (KOA). These attitudes/beliefs are assessed using self-report questionnaires, relying on information one is consciously aware of and willing to disclose. Automatic (ie, implicit) assessment of attitudes does not rely on conscious reflection and may identify features unique from self-report. We developed an implicit association test that explored associations between images of a person moving/twisting their knee (activity) or sitting/standing (rest), and perceived threat (safe vs dangerous). We hypothesised that people with KOA would have greater implicit threat-activity associations (vs pain-free and non-knee pain controls), with implicit attitudes only weakly correlating with self-reported measures (pain knowledge, osteoarthritis/pain/activity beliefs, fear of movement). Participants (n = 558) completed an online survey: 223 had painful KOA (n = 157 female, 64.5 ± 8.9 years); 207 were pain free (n = 157 female, 49.3 ± 15.3 years); and 99 had non-KOA lower limb pain (n = 74 female, 47.5 ± 15.04 years). An implicit association between "danger" and "activity" was present in those with and without limb pain (KOA: 0.36, 95% CI 0.28-0.44; pain free: 0.13, 95% CI 0.04-0.22; non-KOA lower limb pain 0.11, 95% CI -0.03 to 0.24) but was significantly greater in the KOA group than in the pain free ( P < 0.001) and non-KOA lower limb pain ( P = 0.004) groups. Correlations between implicit and self-reported measures were nonsignificant or weak (rho = -0.29 to 0.19, P < 0.001 to P = 0.767). People with painful KOA hold heightened implicit threat-activity associations, capturing information unique to that from self-report questionnaires. Evaluating links between implicit threat-activity associations and real-world behaviour, including physical activity levels, is warranted.

Physical activity and depression symptoms in people with osteoarthritis-related pain: A cross-sectional study

Osteoarthritis is a leading cause of chronic pain and is associated with high rates of depression. Physical activity reduces depression symptoms and pain levels. It remains unknown if physical activity is associated with lower symptoms of depression irrespective of pain levels in individuals with osteoarthritis. We explored whether pain mediated or moderated the relationship between levels of physical activity engagement and depression symptoms. Individuals with osteoarthritis who were waiting for an orthopaedic consultation at a public hospital in Melbourne, Australia, were recruited. Data collected on pain levels, physical activity engagement and depression symptoms. Descriptive statistics were used to summarise participant characteristics. Moderation and mediation analyses were used to establish the impact of pain on the relationship between physical activity and depression, after adjusting for demographic and joint specific characteristics. The results indicated that the inverse association between physical activity and depression depended on the level of pain, such that the association was stronger in people with greater pain. The mediation results confirm that participating in physical activity is indirectly, inversely associated with symptoms of depression through lower levels of pain. The highest levels of pain were associated with the most potential benefit in terms of reduction in symptoms of depression from engaging in physical activity. Physical activity may be particularly important to manage depression symptoms in people with greater osteoarthritis-related pain as patients with the highest pain may have the greatest benefits.

Guideline-based exercise management for hip and knee osteoarthritis: a cross-sectional comparison of healthcare professional and patient beliefs in Ireland

OBJECTIVES

To identify within-stakeholder agreement and between-stakeholder differences in beliefs regarding exercise for osteoarthritis among general practitioners (GPs), physiotherapists (PTs) and people with hip and knee osteoarthritis (PwOA). A secondary objective was to explore the association between referral patterns and beliefs of PwOA.

DESIGN

Cross-sectional.

SETTING

Online surveys administered to GPs, PTs and PwOA in Ireland via social media and healthcare networks.

PARTICIPANTS

421 valid responses (n=161 GPs, n=163 PTs, n=97 PwOA).

PRIMARY AND SECONDARY OUTCOME MEASURES

Nine belief statements related to exercise effectiveness, safety and delivery were rated on a 5-point Likert scale and analysed for within-stakeholder consensus. χ2 tests assessed differences in agreement between groups. Multivariable linear regression models tested associations between beliefs in PwOA and referral to/attendance at physiotherapy.

RESULTS

Positive within-stakeholder consensus (>75% agreement) was reached for most statements (7/9 GPs, 6/9 PTs, 5/9 PwOA). However, beliefs of PwOA were significantly less positive compared with healthcare professionals for six statements. All stakeholders disagreed that exercise is effective regardless of the level of pain. Attendance at physiotherapy (49% of PwOA), rather than referral to physiotherapy from a GP only, was associated with positive exercise beliefs for PwOA (β=0.287 (95% CI 0.299 to 1.821)).

CONCLUSIONS

Beliefs about exercise therapy for osteoarthritis are predominantly positive across all stakeholders, although less positive in PwOA. PwOA are more likely to have positive beliefs if they have seen a PT for their osteoarthritis. Knowledge translation should highlight the effectiveness of exercise for all levels of pain and osteoarthritis disease.

Process of change for people with knee osteoarthritis undergoing cognitive functional therapy: a replicated single-case experimental design study

PURPOSE

To examine the applicability and process of change of Cognitive Functional Therapy (CFT) in the management of pain and disability in people with knee osteoarthritis who were offered knee replacement surgery and had risk factors for poor response to surgery.

METHODS

Single-case experimental design with a mixed-methods, repeated measures approach was used to investigate the process of change through CFT in four participants. Qualitative interviews investigated beliefs, behaviours and coping responses, and self-reported measures assessed pain, disability, psychological factors, and function at 25 timepoints. Study registered with the Australian and New Zealand Clinical Trials Registry (ACTRN12619001491156).

RESULTS

Qualitative data indicate that CFT promoted helpful changes in all participants, with two responses observed. One reflected a clear shift to a biopsychosocial conceptualisation of osteoarthritis, behavioural re-engagement and the view that a knee replacement was no longer necessary. The other response reflected a mixed conceptualisation with dissonant beliefs about osteoarthritis and its management. Psychological and social factors were identified as potential treatment barriers. Overall, quantitative measures supported the qualitative findings.

CONCLUSION

The process of change varies between and within individuals over time. Psychological and social barriers to treatment have implications for future intervention studies for the management of knee osteoarthritis.IMPLICATIONS FOR REHABILITATIONCognitive Functional Therapy is applicable in the management of knee osteoarthritis.Reconceptualisation of osteoarthritis reflected a helpful change.Psychological and social factors emerged as barriers to recovery.

Visual narratives in medicine - Bridging the gap in graphic medicine with an illustrated narrative of osteoarthritis

Objective

Visual narratives have been used in medicine to share information in the form of stories with the potential to improve understanding of conditions and change behaviours. One genre of visual narratives is "graphic medicine", which integrates comics into medical education and the delivery of healthcare. Graphic medicine can maximise the impact of research findings by presenting them in a more accessible format, which may be particularly useful in certain populations, such as those with low levels of health literacy. Those with lower health literacy levels and osteoarthritis (OA) are less likely to manage their condition with guideline recommended management strategies, experience a higher burden of disease, and have lower access to care. Our objectives were to review the current visual narratives in the field of and create a graphic medicine visual narrative based on existing research.

Design

This paper summarises the current visual narratives in OA and presents a graphic medicine visual narrative to illustrate the experience of living with OA. Considerations for the dissemination of visual narratives to target audiences are also discussed.

Results

The most common visual narratives in are infographics, videos, and graphic medicine. A graphic medicine visual narrative, based on previous qualitative work and informed by a framework, was created to illustrate two distinct narratives - impairment and participatory.

Conclusion

Visual narratives remain an emerging field in OA but may serve as a useful resource for patients or clinicians to discuss various aspects of OA management. Future research should evaluate and validate the use of visual narratives in OA.

Prospective validity of a clinical prediction rule for response to non-surgical multidisciplinary management of knee osteoarthritis in tertiary care: a multisite prospective longitudinal study

OBJECTIVES

We tested a previously developed clinical prediction tool-a nomogram consisting of four patient measures (lower patient-expected benefit, lower patient-reported knee function, greater knee varus angle and severe medial knee radiological degeneration) that were related to poor response to non-surgical management of knee osteoarthritis. This study sought to prospectively evaluate the predictive validity of this nomogram to identify patients most likely to respond poorly to non-surgical management of knee osteoarthritis.

DESIGN

Multisite prospective longitudinal study.

SETTING

Advanced practice physiotherapist-led multidisciplinary service across six tertiary hospitals.

PARTICIPANTS

Participants with knee osteoarthritis deemed appropriate for trial of non-surgical management following an initial assessment from an advanced practice physiotherapist were eligible for inclusion.

INTERVENTIONS

Baseline clinical nomogram scores were collected before a trial of individualised non-surgical management commenced.

PRIMARY OUTCOME MEASURE

Clinical outcome (Global Rating of Change) was collected 6 months following commencement of non-surgical management and dichotomised to responder (a little better to a very great deal better) or poor responder (almost the same to a very great deal worse). Clinical nomogram accuracy was evaluated from receiver operating characteristics curve analysis and area under the curve, and sensitivity/specificity and positive/negative likelihood ratios were calculated.

RESULTS

A total of 242 participants enrolled. Follow-up scores were obtained from 210 participants (87% response rate). The clinical nomogram demonstrated an area under the curve of 0.70 (p<0.001), with greatest combined sensitivity 0.65 and specificity 0.64. The positive likelihood ratio was 1.81 (95% CI 1.32 to 2.36) and negative likelihood ratio 0.55 (95% CI 0.41 to 0.75).

CONCLUSIONS

The knee osteoarthritis clinical nomogram prediction tool may have capacity to identify patients at risk of poor response to non-surgical management. Further work is required to determine the implications for service delivery, feasibility and impact of implementing the nomogram in clinical practice.

What are patients' perspectives on the value of physical therapy? A prospective cohort study

PURPOSE

To assess and identify patients' perceptions about the overall value of physical therapy services for musculoskeletal conditions and how these values were associated with their outcomes.

METHODS

The association between the perceived value of physical therapy (as a score) and Patient-Reported Outcomes Measurement Information System (PROMIS) pain interference and physical function at 6-weeks was assessed in a prospective cohort. Generalised linear models were used to identify relationships between the value of physical therapy score and PROMIS outcomes. Kendall's tau was used to identify correlations between responses and outcomes.

RESULTS

A total of 133 participants met the final inclusion criteria. The majority of participants were female (63.9%) with a mean age of 55.53 (SD 15.36) years. A majority of participants (63.9%) reported a previous positive personal experience with physical therapy. There was no significant relationship between perceived value of physical therapy and pain interference (β -0.32, p = 0.07, 95% CI-0.67, 0.03) or physical function (β 0.19, p = 0.29, 95% CI-0.16, 0.54). Stronger beliefs in agreement with the value of non-invasive treatment were significant, but weakly correlated with lower pain interference (r = -0.18, p = 0.048) and higher physical function scores (r = 0.22, p = 0.03).

CONCLUSIONS

Participants had an overall positive perception of the value of physical therapy prior to initiating physical therapy, but this perception was not associated with 6-week pain and function outcomes. A better understanding of the driving factors encouraging patients to seek physical therapy services is needed to provide value-based care.

Illness perceptions in people with chronic and disabling non-specific neck pain seeking primary healthcare: a qualitative study

BACKGROUND

Illness perceptions can affect the way people with musculoskeletal pain emotionally and behaviorally cope with their health condition. Understanding patients illness perceptions may help facilitate patient-centered care. The purpose of this study was to explore illness perceptions and the origin of those perceptions in people with chronic disabling non-specific neck pain seeking primary care.

METHODS

A qualitative study using a deductive and inductive analytical approach was conducted in 20 people with persistent (> 3 months) and disabling (i.e., Neck Disability Index ≥ 15) neck pain. Using a semi-structured format, participants were interviewed about their illness perceptions according to Leventhal's Common Sense Model. Purposive sampling and member checking were used to secure validity of study results.

RESULTS

Participants reported multiple symptoms, thoughts and emotions related to their neck pain, which continuously required attention and action. They felt trapped within a complex multifactorial problem. Although some participants had a broader biopsychosocial perspective to understand their symptoms, a biomedical perspective was dominant in the labelling of their condition and their way of coping (e.g., limiting load, building strength and resilience, regaining mobility, keep moving and being meaningful). Their perceptions were strongly influenced by information from clinicians. Several participants indicated that they felt uncertain, because the information they received was contradictory or did not match their own experiences.

CONCLUSION

Most participants reported that understanding their pain was important to them and influenced how they coped with pain. Addressing this 'sense making process' is a prerequisite for providing patient-centered care.

Emerging trends and patterns in healthcare-seeking behavior: A systematic review

OBJECTIVES

The study of healthcare-seeking behavior is essential for optimizing resource allocation and improving healthcare services. Its complexity and diversity have made it a prominent research area. Understanding factors influencing healthcare-seeking decisions allows targeted interventions and policy development to address barriers and ensure equitable access to quality healthcare for diverse populations. Such research plays a vital role in enhancing healthcare outcomes and overall population health.

METHODS

The study utilized a systematic quantitative literature review approach, employing the Web of Science (WOS) Core Collection and PubMed databases as data sources. Additionally, bibliometric tools such as CiteSpace and VOSviewer were employed for analysis and visualization of the literature.

RESULTS

A comprehensive statistical analysis and visualization were performed on the annual publication volume, publication countries, journals, keywords, and keyword co-occurrence patterns up until 2023. Through this analysis, a framework was established, identifying the determinants and fundamental elements of healthcare-seeking behavior. These findings contribute to the advancement of research in this field and inform future studies and interventions aimed at improving healthcare-seeking behavior.

CONCLUSIONS

Based on the aforementioned literature review and framework, several conclusions were drawn. The determinants that facilitate healthcare-seeking behavior include improving health education awareness, enhancing healthcare resources, reducing costs, and ensuring system soundness. Additionally, providing social environment support was found to be crucial. Furthermore, the fundamental elements of healthcare-seeking behavior were identified as healthcare demand, healthcare choices, and the process of diagnosis and treatment. These findings provide valuable insights for developing interventions and policies to promote optimal healthcare-seeking behavior.

A cross sectional study exploring the relationship of self-reported physical activity with function, kinesiophobia, self-efficacy and quality of life in an Asian population seeking care for knee osteoarthritis

BACKGROUND

Physical activity is a guideline-recommended first-line intervention for people with knee osteoarthritis. Physical activity levels, and its potential correlates, is underexplored in Asian populations with knee osteoarthritis.

METHODS

Participants enrolled in a longitudinal study in Singapore self-reported physical activity (UCLA activity score), function (Knee Osteoarthritis Outcome Score [KOOS-12]), kinesiophobia (Brief fear of movement [BFOM]), self-efficacy (ASES-8), and quality of life (EQ-5D-5 L). One-Way ANOVA was used to test the difference in outcomes between UCLA categories, while ordinal logistic regression was used to identify the associated factors to physical activity level.

RESULTS

Seventy-three percent of all enrolled participants (n = 311/425) reported either inactivity or low physical activity (median 4, IQR 3-5). Significant, weak, positive correlations were observed be-tween UCLA activity score and either KOOS-12 (Spearman's rho: 0.1961; p < 0.001), ASES-8 (0.1983; p = 0.004), or EQ-5D-5 L (0.2078; p < 0.001). A significant, weak, negative correlation was observed between physical activity and BFOM (-0.2183; p < 0.001). Significant differences in function between groups (moderate vs. inactive or low physical activity) were not clinically important. Participants with obesity, from the eldest age category (i.e. ≥75), or who identified as Malay or female, were less physically active than those with a healthy BMI, below the age of 54, or who identified as Chinese or male, respectively.

CONCLUSION

Healthcare professionals in Asia should be aware of the large proportion of people with knee osteoarthritis who are either inactive or have low physical activity levels. Screening for, and offering interventions to promote, physical activity and its correlates should be prioritised.

Development of a Digital Health Intervention to Support Patients on a Waitlist for Orthopedic Specialist Care: Co-Design Study

BACKGROUND

The demand for orthopedic specialist consultations for patients with osteoarthritis in public hospitals is high and continues to grow. Lengthy waiting times are increasingly affecting patients from low socioeconomic and culturally and linguistically diverse backgrounds who are more likely to rely on public health care.

OBJECTIVE

This study aimed to co-design a digital health intervention for patients with OA who are waiting for an orthopedic specialist consultation at a public health service, which is located in local government areas (LGAs) of identified social and economic disadvantage.

METHODS

The stakeholders involved in the co-design process included the research team; end users (patients); clinicians; academic experts; senior hospital staff; and a research, design, and development agency. The iterative co-design process comprised several key phases, including the collation and refinement of evidence-based information by the research team, with assistance from academic experts. Structured interviews with 16 clinicians (female: n=10, 63%; male: n=6, 38%) and 11 end users (age: mean 64.3, SD 7.2 y; female: n=7, 64%; male: n=4, 36%) of 1-hour duration were completed to understand the requirements for the intervention. Weekly workshops were held with key stakeholders throughout development. A different cohort of 15 end users (age: mean 61.5, SD 9.7 y; female: n=12, 80%; male: n=3, 20%) examined the feasibility of the study during a 2-week testing period. The System Usability Scale was used as the primary measure of intervention feasibility.

RESULTS

Overall, 7 content modules were developed and refined over several iterations. Key themes highlighted in the clinician and end user interviews were the diverse characteristics of patients, the hierarchical structure with which patients view health practitioners, the importance of delivering information in multiple formats (written, audio, and visual), and access to patient-centered information as early as possible in the health care journey. All content was translated into Vietnamese, the most widely spoken language following English in the local government areas included in this study. Patients with hip and knee osteoarthritis from culturally and linguistically diverse backgrounds tested the feasibility of the intervention. A mean System Usability Scale score of 82.7 (SD 16) was recorded for the intervention, placing its usability in the excellent category.

CONCLUSIONS

Through the co-design process, we developed an evidence-based, holistic, and patient-centered digital health intervention. The intervention was specifically designed to be used by patients from diverse backgrounds, including those with low health, digital, and written literacy levels. The effectiveness of the intervention in improving the physical and mental health of patients will be determined by a high-quality randomized controlled trial.

From sceptic to believer: Acceptability of cognitive muscular therapyTM , a new intervention for knee osteoarthritis

BACKGROUND

Cognitive Muscular TherapyTM (CMT) is an integrated behavioural intervention developed for knee osteoarthritis. CMT teaches patients to reconceptualise the condition, integrates muscle biofeedback and aims to reduce muscle overactivity, both in response to pain and during daily activities. This nested qualitative study explored patient and physiotherapist perspectives and experiences of CMT.

METHODS

Five physiotherapists were trained to follow a well-defined protocol and then delivered CMT to at least two patients with knee osteoarthritis. Each patient received seven individual clinical sessions and was provided with access to online learning materials incorporating animated videos. Semi-structured interviews took place after delivery/completion of the intervention and data were analysed at the patient and physiotherapist level.

RESULTS

Five physiotherapists and five patients were interviewed. All described a process of changing beliefs throughout their engagement with CMT. A framework with three phases was developed to organise the data according to how osteoarthritis was conceptualised and how this changed throughout their interactions with CMT. Firstly, was an identification of pain beliefs to be challenged and recognition of how current beliefs can misalign with daily experiences. Secondly was a process of challenging and changing beliefs, validated through new experiences. Finally, there was an embedding of changed beliefs into self-management to continue with activities.

CONCLUSION

This study identified a range of psychological changes which occur during exposure to CMT. These changes enabled patients to reconceptualise their condition, develop a new understanding of their body, understand psychological processes, and make sense of their knee pain.

A self-directed digital exercise program for hip osteoarthritis ("My Hip Exercise"): protocol for a randomised controlled trial

BACKGROUND

Hip osteoarthritis (OA) is a leading global cause of chronic pain and disability. Given there is no cure for OA, patient self management is vital with education and exercise being core recommended treatments. However, there is under-utilisation of these treatments due to a range of clinician and patient factors. Innovative service models that increase patient accessibility to such treatments and provide support to engage are needed. This study primarily aims to determine the effects of a self-directed digital exercise intervention comprising online education and exercise supported by a mobile app to facilitate adherence on the primary outcomes of changes in hip pain during walking and patient-reported physical function at 24-weeks when compared to online education control for people with hip OA.

METHODS

We will conduct a two-arm, superiority parallel-design, randomised controlled trial involving 182 community volunteers aged 45 years and over, with painful hip OA. After completing the baseline assessment, participants will be randomly assigned to either: i) digital exercise intervention; or ii) digital education (control). Participants randomised to the intervention group will have access to a website that provides information about hip OA and its management, advice about increasing their physical activity levels, a 24-week lower limb strength exercise program to be undertaken at home three times per week, and a mobile app to reinforce home exercise program adherence. Participants in the control group will have access to a website containing only information about hip OA and its management. All participants will be reassessed at 24 weeks after randomisation. Primary outcomes are severity of hip pain while walking using an 11-point numeric rating scale and physical function using the Western Ontario and McMaster Universities Osteoarthritis Index subscale. Secondary outcomes are the Hip dysfunction and Osteoarthritis Outcome Score subscales of pain, hip-related quality of life, and function, sports and recreational activities; global change in hip condition; health-related quality of life; measures of physical activity levels; fear of movement; self efficacy for pain and for exercise; and use of oral pain medications.

DISCUSSION

Innovative and scalable approaches to OA education, physical activity, and exercise are required in order to improve exercise participation/engagement and mitigate physical inactivity in the hip OA population. This will help minimise the burden of this major public health issue on individuals and society.

Toe-in and toe-out gait retraining interventions to reduce proxy measures of medial knee joint load in people with medial knee osteoarthritis: Protocol for a randomised placebo-controlled trial

OBJECTIVE

Our primary aim is to determine the effect of a six-week toe-in, toe-out and active placebo gait retraining program on proxy measures of medial knee joint load and varus thrust in people with medial knee osteoarthritis. Our secondary aim is to determine the intervention effects on patient reported outcomes and physical function and determine if changes are maintained at three-months follow-up.

METHODS

We will conduct a three-arm randomised placebo-controlled trial. Ninety participants with medial knee osteoarthritis will be randomised and stratified via varus thrust status (presence/absence) to: toe-in, toe-out or placebo gait retraining (an intervention that does not change proxy measures of medial knee joint load). The intervention involves weekly clinician-supervised sessions with biofeedback, knee osteoarthritis education, motor learning and behaviour change principles, and daily gait retraining practice. Primary outcomes are proxy measures of medial knee joint load: knee adduction moment (early- and late-stance peaks and impulse), and varus thrust (presence/absence). Secondary outcomes include pain, physical function, medication and health care utilisation, quality of life, work ability, treatment blinding, intervention credibility and other biomechanical outcomes. Assessment timepoints are at baseline, six weeks (post intensive training), and three-months following the six-week intervention.

CONCLUSION

Our trial will determine whether toe-in or toe-out gait retraining is most effective at reducing proxy measures of medial knee joint load and varus thrust in people with medial knee osteoarthritis. This study will also evaluate if toe-in or toe-out gait retraining interventions are superior at improving pain, physical function and quality of life compared to placebo.

CLINICAL TRIAL REGISTRATION

This clinical trial protocol is registered with the Australian New Zealand Clinical Trials Registry (ACTRN12621000414819).

The relationships between pain-associated psychological distress, pain intensity, patient expectations, and physical function in individuals with musculoskeletal pain: A retrospective cohort study

INTRODUCTION

The presence of pain-associated psychological distress (PAPD) in musculoskeletal disorders, including negative mood, fear-avoidance, and lack of positive affect/coping, is associated with prolonged disability. The importance of considering psychological influence on pain is well known, but practical ways of addressing it are not as straightforward. Identifying relationships between PAPD and pain intensity, patient expectations, and physical function may guide the development of future studies that assess causality and inform clinical practice.

OBJECTIVE

To assess the relationship between PAPD measured by the Optimal Screening for Prediction of Referral and Outcome-Yellow Flag tool, and baseline pain intensity, expectations of treatment effectiveness, and self-reported physical function at discharge.

DESIGN

Retrospective cohort study.

SETTING

Hospital-based outpatient physical therapy.

PARTICIPANTS

Patients 18 to 90 years old with spinal pain or lower extremity osteoarthritis.

MAIN OUTCOME MEASURES

Pain intensity and patient expectations of treatment effectiveness at intake, and self-reported physical function at discharge.

RESULTS

A total of 534 patients, 56.2% female, median (interquartile range [IQR]) age 61 (21) years with an episode of care between November 2019 and January 2021 were included. A multiple linear regression showed a significant association between PAPD and pain intensity with 6.4% (p < .001) of the variance explained. PAPD explained 3.3% (p < .001) of the variance in patient expectations. One additional yellow flag present resulted in a 0.17-point increase in pain intensity and 1.3% decrease in patient expectations. PAPD was also associated with physical function with 3.2% (p < .001) of the variance explained. PAPD explained 9.1% (p < .001) of the variance in physical function at discharge in the low back pain cohort only when assessed independently by body region.

CONCLUSION

These findings support the theory that the pain experience is complex and multiple factors should be considered when evaluating a patient with musculoskeletal pain. Clinicians who have identified PAPD may consider these relationships when planning or modifying interventions and pursuing multidisciplinary collaboration.

Effects of Hip Pain Diagnostic Labels and Their Explanations on Beliefs About Hip Pain and How to Manage It: An Online Randomized Controlled Trial

OBJECTIVES: To compare the effects of diagnostic labels and their explanations on people's beliefs about managing hip pain. DESIGN: Online randomized controlled trial involving 626 participants. METHODS: Participants aged ≥45 years with and without hip pain considered a hypothetical scenario (initial doctor consultation for hip pain). They were randomized to receive a diagnostic label and explanation of (1) hip osteoarthritis, (2) persistent hip pain, or (3) hip degeneration. Primary outcomes were the beliefs (1) exercise would damage the hip and (2) surgery is necessary at some stage (scales, 0 = definitely would not/unnecessary, 10 = definitely would/necessary). Secondary outcomes included beliefs about other treatments and care providers. RESULTS: Compared to hip degeneration, participants who were allocated to hip osteoarthritis and persistent hip pain believed exercise was less damaging (mean difference -1.3 [95% CI: -1.9, -0.7] and -1.8 [-2.3, -1.2], respectively) and surgery less necessary (-1.5 [-2.1, -1.0] and -2.2 [-2.7, -1.6], respectively). Compared to hip osteoarthritis, participants who were allocated to persistent hip pain believed surgery was less necessary (-0.7 [-1.2, -0.1]), but not that exercise was less damaging (-0.5 [-1.1, 0.1]). Compared to hip degeneration, participants who were allocated to hip osteoarthritis and persistent hip pain were less concerned about their hip and believed exercise and care from an exercise and sports physician, rheumatologist, or physiotherapist would be more helpful, and care from an orthopaedic surgeon less helpful. CONCLUSIONS: People who were allocated a diagnostic label and explanation of hip osteoarthritis or persistent hip pain believed exercise was less damaging and surgery less necessary for a hip problem than hip degeneration.

Difficulties Experienced by Patients with Knee Osteoarthritis during the Conservative Treatment Process: A Qualitative Study

BACKGROUND AND OBJECTIVES

This study aimed to investigate the difficulties faced by patients with knee osteoarthritis during the conservative treatment process.

MATERIALS AND METHODS

We included twenty-one patients who were diagnosed with knee osteoarthritis and admitted to the orthopedics and traumatology outpatient clinic of the hospital where the researcher worked between January 2022 and April 2022. We interviewed each patient using semi-structured face-to-face interviews. To analyze the interviews, the researcher used the directed content analysis method. Data were analyzed using the NVIVO 10 software package. The authors and the expert trained in qualitative research who generously supported the authors continued the analysis independently of each other until they reached a consensus.

RESULTS

After analysis of the interviews held with the participants, the following three main themes emerged: lack of information about conservative treatment, frequent change of physicians, and non-compliance with lifestyle changes. Two sub-themes were identified within the theme of frequent change of physicians: distrusting health personnel, and not being able to make an appointment. In addition, most of the patients were not knowledgeable enough about either the definition of the disease or the treatment process. These patients stated that they were confused because they had to change physicians frequently; thus, they distrusted physicians because each physician they visited made a different plan for the treatment process.

CONCLUSIONS

At the end of the study, we determined that during the conservative treatment process of patients with knee osteoarthritis, a multidisciplinary approach should be adopted, and orthopedic surgeons, physical therapy and rehabilitation physicians, dietitians, and physiotherapists should be in harmony with the patient. In addition, health personnel should provide patients with detailed information to eliminate questions they have during the conservative treatment process. In order for healthcare team members to establish a trusting relationship between the patients, they should allocate enough time to the patient.

Item development and pre-testing of an Osteoarthritis Conceptualisation Questionnaire to assess knowledge and beliefs in people with knee pain

Many people with osteoarthritis hold beliefs that physical activity is unhelpful or dangerous for their joints, despite high-level evidence suggesting otherwise. Recent advances in scientific understanding of osteoarthritis have led to new treatments that target an individual's understanding both of their condition and the importance of best-practice management strategies, such as physical activity. Conceptual change has been proposed as an important mechanism by which cognitive interventions, such as pain science education, may reduce pain and improve function. There are currently no specific assessments of osteoarthritis conceptualisation to determine the effectiveness of cognitive interventions in effecting conceptual change in people with knee osteoarthritis. Therefore, we aimed to develop an item bank, as the first phase of developing a questionnaire to assess people's conceptualisations about their knee osteoarthritis and the role of physical activity in managing their osteoarthritis. Using a guideline-informed mixed method design, a panel of experts identified domains relevant to conceptualisation about knee osteoarthritis and physical activity (knowledge, beliefs, understanding) based upon available evidence. The panel created 33 provisional items. Qualitative and quantitative pretesting were used to explore how people with knee osteoarthritis understood the provisional items. Eighteen people with knee osteoarthritis completed cognitive interviews about their comprehension of the wording/grammar of each provisional item. The provisional item bank was field tested with 100 people with knee osteoarthritis. Readability was adequate with a Flesch reading ease score of 57.7. Although 14.7% used the 'Strongly agree' response option, only 3.4% of responses used the 'Strongly disagree' option, suggesting possible response bias. Predictive quality testing identified relevant modifications to the questionnaire instructions. The panel of experts appraised the qualitative data to assess whether and how items should be modified to address the problems identified, resulting in a final item bank of 45 items that can be evaluated for psychometric properties in future research.

Within-person change in patient-reported outcomes and their association with the wish to undergo joint surgery during a digital first-line intervention for osteoarthritis

AIM

To study the association between within-person changes in patient-reported outcomes (PROMs) and wish for joint surgery during participation in a digital first-line intervention comprising exercise and education for knee/hip osteoarthritis (OA).

METHODS

Retrospective observational registry study. Participants enrolled between June 1, 2018 and October 30, 2021, with follow-up data at three months (n = 13,961). We used asymmetric fixed effect (conditional) logistic regressions to study the association between change in wish to undergo surgery at last available time point (3, 6, 9, or 12 months) and improvement or worsening of PROMs pain (0-10), quality of life (QoL) (EQ5D-5L, 0.243-0.976), overall health (0-10), activity impairment (0-10), walking difficulties (yes/no), fear of movement (yes/no), and Knee/Hip injury and Osteoarthritis Outcome Score 12 Items (KOOS-12/HOOS-12, 0-100) function and QoL subscales.

RESULTS

The proportion of participants wishing to undergo surgery declined by 2% (95% CI: 1.9, 3.0), from 15.7% at the baseline to 13.3% at 3 months. Generally, improvements in PROMs were associated with reduced likelihood of wishing for surgery, while worsening was associated with increased likelihood. For pain, activity impairment EQ-5D and KOOS/HOOS QoL, a worsening led to a change in the probability of wish for surgery of larger absolute magnitude than an improvement in the same PROM.

CONCLUSIONS

Within-person improvements in PROMs are associated with reduced wish for surgery while worsenings with an increased wish for surgery. Larger improvements in PROMs may be needed to match the magnitude of the change in wish for surgery associated with a worsening in the same PROM.

Comprehensiveness, accuracy, quality, credibility and readability of online information about knee osteoarthritis

BACKGROUND

People are increasingly using the Internet to retrieve health information about chronic musculoskeletal conditions, yet content can be inaccurate and of variable quality.

OBJECTIVE

To summarise (i) comprehensiveness, (ii) accuracy and clarity, iii) quality of information about treatment choices, (iv) credibility and (v) readability of online information about knee osteoarthritis.

METHOD

Systematic appraisal of website content. Searches for "knee osteoarthritis" and "knee arthritis" were performed using Google and Bing (October 2020). The top 20 URLs of each search were screened for eligibility. Comprehensiveness, accuracy and clarity of content were matched against 14 pre-defined topic descriptors. DISCERN and HONcode were used to measure quality of information about treatment choices and website credibility, respectively. Flesch Reading Ease and Flesch-Kincaid Grade Level tests were used to assess readability.

RESULTS

Thirty-five websites were included. Websites were generally comprehensive (median, range = 12, 0-14/14) with descriptors available for 67% (n = 330/490) of topics across all websites, but only 35% (n = 116/330) were accurate and clear. Quality of information about treatment choices was generally low (median DISCERN score, range = 40, 16-56/80). Credibility descriptors were present for 65% (n = 181/280) of items, with 81% (n = 146/181) of descriptors being clear. Median Flesch reading ease was 53 (range = 21-74), and Flesch-Kincaid grade level was 8 (range = 5-11).

CONCLUSION

Few websites provide accurate and clear content aligned to key research evidence. Quality of information about treatment choices was poor, with large variation in comprehensiveness, credibility and readability.

IMPLICATIONS

Careful consideration is required by clinicians to identify what online information people with knee osteoarthritis have accessed and to address misinformed beliefs.

Affordance-based practice: An ecological-enactive approach to chronic musculoskeletal pain management

BACKGROUND

The biomedical understanding of chronic musculoskeletal pain endorses a linear relationship between noxious stimuli and pain, and is often dualist or reductionist. Although the biopsychosocial approach is an important advancement, it has a limited theoretical foundation. As such, it tends to be misinterpreted in manners that lead to artificial boundaries between the biological, psychological, and social, with fragmented and polarized clinical applications.

OBJECTIVE

We present an ecological-enactive approach to complement the biopsychosocial model. In this approach, the disabling aspect of chronic pain is characterized as an embodied, embedded, and enactive process of experiencing a closed-off field of affordances (i.e., shutting down of action possibilities). Pain is considered as a multi-dimensional, multicausal, and dynamic process, not locatable in any of the biopsychosocial component domains. Based on a person-centered reasoning approach and a dispositional view of causation, we present tools to reason about complex clinical problems in face of uncertainty and the absence of 'root causes' for pain. Interventions to open up the field of affordances include building ability and confidence, encouraging movement variability, carefully controlling contextual factors, and changing perceptions through action according to each patient's self-identified goals. A clinical case illustrates how reasoning based on an ecological-enactive approach leads to an expanded, multi-pronged, affordance-based intervention.

CONCLUSIONS

The ecological-enactive perspective can provide an overarching conceptual and practical framework for clinical practice, guiding and constraining clinicians to choose, combine, and integrate tools that are consistent with each other and with a true biopsychosocial approach.

Clinical reasoning in managing chronic hip pain: One in two Australian and New Zealand physiotherapists diagnosed a case vignette with clinical criteria for hip OA as hip OA. A cross-sectional survey

OBJECTIVES

Using a case vignette of an adult (George) presenting with hip pain consistent with hip OA, this study aimed to describe: (a) whether physiotherapists make diagnoses and identify bodily structures using either patient history and/or physical examination findings; (b) which diagnoses and bodily structures physiotherapists attribute to the hip pain; (c) how confident physiotherapists were in their clinical reasoning using patient history and physical examination findings; (d) what treatments physiotherapists would offer to George.

METHODS

We conducted a cross-sectional online survey of physiotherapists in Australia and New Zealand. We used descriptive statistics to analyse closed questions and content analysis for open-text responses.

RESULTS

Two hundred and twenty physiotherapists completed the survey (39% response-rate). After receiving the patient history, 64% diagnosed George's pain and 49% of these as hip OA; 95% attributed George's pain to a bodily structure(s). After receiving the physical examination, 81% diagnosed George's hip pain and 52% of these as hip OA; 96% attributed George's hip pain to a bodily structure(s). Ninety-six percent of respondents were at least somewhat confident in their diagnosis after the patient history, and 95% were similarly confident after the physical examination. Most respondents offered advice (98%) and exercise (99%), but fewer offered treatments for weight loss (31%), medication (11%), and psychosocial factors (<15%).

DISCUSSION

About half of the physiotherapists that diagnosed George's hip pain made a diagnosis of hip OA, despite the case vignette including clinical criteria for a diagnosis of OA. Physiotherapists offered exercise and education, but many physiotherapists did not offer other clinically indicated and recommended treatments, such as weight loss and sleep advice.

Variation in the utilisation of physiotherapy in patients with advanced knee osteoarthritis prior to total knee arthroplasty a systematic review

INTRODUCTION

Due to demographic changes and increasing knee osteoarthritis (KOA) prevalence, the incidence of total knee arthroplasties (TKA) is constantly rising. Clinical practice guidelines for the treatment of KOA unanimously recommend non-surgical interventions such as exercise, education, and weight reduction in overweight patients. The aim of this systematic review is to determine the proportion of patients with end-stage KOA who attended physiotherapy (PT) prior to TKA.

METHODS

A systematic literature search was carried out in the medical databases MEDLINE (via Pubmed), PEDro, and EBSCO in August of 2022. Studies were included regardless of their design, if they reported the proportion of patients with a diagnosis of primary KOA, who participated in PT prior to undergoing TKA. Study quality assessment was performed by two independent authors using the Joanna Briggs Institutes Checklist for studies reporting prevalence data. Results were presented by using a narrative synthesis.

RESULTS

Eighteen studies, comprising 579,718 patients, were identified in this systematic review. PT utilisation prior to TKA ranged from 10% to 73% for patients with advanced KOA. Only two studies showed PT utilisation rates of 60% or higher. Female gender, higher income, better socioeconomic status, higher education levels, older age were associated with PT utilisation. Data for other predicting factors was conflicting.

DISCUSSION

This review shows substantial variation in the utilisation of PT in patients with end-stage KOA. This is concerning, considering the uniform recommendation from clinical practice guidelines for non-surgical treatments like exercise and education in patients with KOA, which are mostly provided by physiotherapists.

How people with knee pain understand why their pain changes or remains the same over time: A qualitative study

Objectives

Guidelines recommend knee osteoarthritis pain management based on biopsychosocial mechanisms. Treatment adherence and effectiveness may be affected if there is a mismatch between patient perspectives and treatment focus. We therefore examined patient perspectives on mechanisms of their knee pain, why it persisted or changed over the past year, whether their understanding had changed, and whether their understanding aligned with that of others with whom they interact.

Methods

Individuals with chronic knee pain (n ​= ​50) were purposively recruited from the Knee Pain and related health In the Community (KPIC) cohort to represent worsened, improved, or unchanged pain or anxiety between baseline and one year later. Framework analysis, a comparative form of thematic analysis, was used across transcripts of semi-structured telephone interviews.

Results

Data were collapsed into themes of diagnosis, joint structure, ageing, physical activity, weight management, and treatment. Participants focused on biomechanical rather than psychological pain mechanisms. Some participants attributed pain improvement to increased and others to decreased physical activity. Participants reported no change in their understanding of their pain during the preceding year, but that their attitudes to pain, for example acceptance, had changed. Participants reported that they and others around them lacked understanding of their pain and why it did or did not change.

Conclusion

People report a predominantly biomechanical understanding of why their knee pain remains constant or changes over time. Clinicians should support patients to develop a biopsychosocial understanding of knee pain aligned to treatment across the range of biological, psychological, and social modalities.
