[PMID: 39116992 DOI: 10.1016/j.joca.2024.08.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/05/2024] [Revised: 07/08/2024] [Accepted: 08/01/2024] [Indexed: 08/10/2024]
Abstract
This Year in Review presents key highlights from recent research relating to osteoarthritis rehabilitation and its outcomes, defined as any non-pharmacological and non-surgical treatment that aims to improve osteoarthritis symptoms at any joint. Three databases (Medline, Embase, and CINAHL Plus) were searched between 1 March 2023 to 12 March 2024. Relevant studies were chosen based on the predefined inclusion/exclusion criteria, perceived clinical importance, quality, controversy in the field, or personal interest, and organised into four overarching themes (with 1-5 sub-themes each). The first theme related to uncertainties regarding exercise benefits. New work has challenged the clinical effectiveness of exercise on symptoms, as well as highlighted uncertainty around our understanding of both mechanisms of effects, how to enhance effectiveness and adherence, and which subgroups of people are more or less likely to improve with exercise. However, we also highlight new work confirming the role of exercise as a first-line management strategy. The second theme related to digital modes of service delivery. There was new evidence to support its effectiveness in improving symptoms and clear potential for creating and evaluating new mobile apps. New work also highlighted the potential future role artificial intelligence can have in providing treatment information and recommendations. The third theme related to patient education, and the call for change to the impairment-based narrative that prevails in osteoarthritis information. The fourth theme is related to weight loss. New work compared the effectiveness of different weight loss diets and explored alternative models of weight loss delivery.

Osteoarthritis Cartilage 2024:S1063-4584(24)01315-3. [PMID: 39068982 DOI: 10.1016/j.joca.2024.07.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/01/2024] [Revised: 06/21/2024] [Accepted: 07/10/2024] [Indexed: 07/30/2024]
Abstract
OBJECTIVE To describe the use of non-steroidal anti-inflammatory drugs (NSAID), opioids, and physiotherapy (PT) among persons with newly diagnosed knee or hip osteoarthritis (OA) with and without NSAID contraindications or precautions. DESIGN We used population-based register data to identify adults aged ≥35 as of January 1, 2014, residing in Skåne region (Sweden) between 2004 and 2013, without a previous knee or hip OA diagnosis. Among this cohort, we identified people with incident knee or hip OA diagnosis between 2014 and 2018 and the presence of contraindications to or precautions for oral NSAIDs at the time of OA diagnosis. We estimated the risk of 1) regular oral NSAID use, 2) regular opioid use, and 3) PT during the first year after diagnosis among those with vs. without contraindications or precautions using confounder-adjusted logistic regression with standardization. RESULTS We identified 35,173 persons with newly diagnosed OA, of whom 3257 and 8351 had ≥1 contraindication to oral NSAIDs and ≥1 precaution, respectively. Overall, 27% of individuals used oral NSAIDs (with or without opioids or PT), 10% used opioids, and 57% attended PT. Among patients with contraindications, 21% used oral NSAIDs compared to 31% without (absolute adjusted difference -0.06 (95% CIs: -0.08, -0.05)), 53% vs 59% used PT (adjusted difference -0.03 (-0.05, -0.01)), while 14% vs. 8% had prescribed dispensed opioids (adjusted difference 0.02 (0.01, 0.03)). Similar results were observed for those with precautions. CONCLUSIONS We highlight the need for safer treatment options. People with OA and contraindications/precautions to NSAIDs have a higher risk of opioid use, slightly lower risk of PT use, and continue to be prescribed NSAIDs.

Are the Effects of Resistance Exercise on Pain and Function in Knee and Hip Osteoarthritis Dependent on Exercise Volume, Duration, and Adherence? A Systematic Review and Meta-Analysis. Arthritis Care Res (Hoboken) 2024; 76:821-830. [PMID: 38317328 DOI: 10.1002/acr.25313] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Revised: 01/24/2024] [Accepted: 02/01/2024] [Indexed: 02/07/2024]
Abstract
OBJECTIVE The purpose of this study was to determine dose parameters for resistance exercise associated with improvements in pain and physical function in knee and hip osteoarthritis (OA) and whether these improvements were related to adherence. METHODS We searched six databases, from inception to January 28, 2023, for randomized controlled trials comparing land-based, resistance exercise-only interventions with no intervention, or any other intervention. There were four subgroups of intervention duration: 0 to <3 months, 3 to 6 months, >6 to <12 months, ≥12 months. The between-group effect was calculated for immediate postintervention pain and physical function (activities of daily living [ADL] and sports/recreation [SPORT]). RESULTS For both knee and hip, data from 280 studies showed moderate benefit for pain, physical function ADL, and physical function SPORT in favor of interventions 3 to 6 months. For the knee, there was also a moderate benefit for physical function ADL in favor of interventions >6 to <12 months. From 151 knee and hip studies that provided total exercise volume data (frequency, time, duration), there was no association between volume with the effect size for pain and physical function. A total of 74 studies (69 knee, 5 hip) reported usable adherence data. There was no association between adherence with the effect size for pain and physical function. CONCLUSION In knee and hip OA, resistance exercise interventions 3 to 6 months (and for the knee >6 to <12 months) duration improve pain and physical function. Improvements do not depend on exercise volume or adherence, suggesting exercise does not require rigid adherence to a specific dose.

Abstract
Exercise is universally recommended as a primary strategy for the management of knee osteoarthritis (OA) pain. The recommendations are based on results from more than 100 randomized controlled trials (RCTs) that compare exercise to no-attention control groups. However, due to the inherent difficulties with adequate placebo control, participant blinding and the use of patient-reported outcomes, the existing RCT evidence is imperfect. To better understand the evidence used to support a causal relationship between exercise and knee OA pain relief, we examined the existing evidence through the Bradford Hill considerations for causation. The Bradford Hill considerations, first proposed in 1965 by Sir Austin Bradford Hill, provide a framework for assessment of possible causal relationships. There are 9 considerations by which the evidence is reviewed: Strength of association, Consistency, Specificity, Temporality, Biological Gradient (Dose-Response), Plausibility, Coherence, Experiment, and Analogy. Viewing the evidence from these 9 viewpoints did neither bring forward indisputable evidence for nor against the causal relationship between exercise and improved knee OA pain. Rather, we conclude that the current evidence is not sufficient to support claims about (lack of) causality. With our review, we hope to advance the continued global conversation about how to improve the evidence-based management of patients with knee OA.

Abstract
Physical activity (PA) and weight management are critical components of an effective knee and hip osteoarthritis (OA) management plan, yet most people with OA remain insufficiently active and/or overweight. Clinicians and their care teams play an important role in educating patients with OA about PA and weight management, eliciting patient motivation to engage in these strategies, and referring patients to appropriate self-management interventions. The purpose of this review is to educate clinicians about the current public health and clinical OA guidelines for PA and weight management and highlight a variety of evidence-based self-management interventions available in community and clinical settings and online.

Abstract
OBJECTIVE We systematically reviewed the literature to identify comparative studies of core treatments (exercise, education, or weight management), adjunct treatments (e.g. electrotherapeutical modalities, bracing), or multimodal treatments (core plus other treatments), for treating osteoarthritis (OA) complaints, published between 1 March 2022 and 1 March 2023. DESIGN We searched three electronic databases for peer-reviewed comparative studies evaluating core treatments, adjunct treatments, or multimodal treatments for OA affecting any joint, in comparison to other OA treatments. Two authors independently screened records. Methodological quality was assessed using the Physiotherapy Evidence Database (PEDro) scale. A narrative synthesis focusing on pain and function outcomes was performed in studies with a mean sample size of at least 46 participants per treatment arm. RESULTS 33 publications (28 studies), 82% with PEDro ratings of good or excellent, were eligible for narrative synthesis: 23 studies evaluated knee OA; one knee OA or chronic low back pain; two knee or hip OA; one hip OA only; and one thumb OA. No studies identified a dose, duration or type of exercise that resulted in better pain or function outcomes. Core treatments generally showed modest benefits compared to no or minimal intervention controls. CONCLUSIONS Rehabilitation research continues to be focused on the knee. Most studies are not adequately powered to assess pain efficacy. Further work is needed to better account for contextual effects, identify treatment responder characteristics, understand treatment mechanisms, and implement guideline care.

Abstract
There is still a lot of ambiguity about the link between physical activity (PA), sedentary behaviors (SBs) and osteoarthritis (OA). This study aimed to investigate the causal relationship of PA/SBs on the risk of OA. A univariate and multivariate Mendelian randomization (MR) analysis was conducted to investigate the causal effect of five PA phenotypes and three SB phenotypes on overall OA, knee OA, hip OA, total hip arthroplasty, and total knee arthroplasty (TKA). MR methods used were inverse-variance weighting, MR-Egger regressions, and weighted median. Sensitivity analysis examined horizontal pleiotropy and heterogeneity, and confirmed the reliability of the results. After false discovery rate, light do-it-yourself (DIY) activities decreased the risk for overall OA (OR: 0.32, 95% CI 0.16-0.65), and knee OA (OR: 0.26, 95% CI 0.12-0.51). Resulting in a decreased risk of walking for pleasure on overall OA (OR: 0.87, 95% CI 0.70-1.04) and knee OA (OR: 0.14, 95% CI 0.06-0.32) was also observed. Television viewing, however, significantly increased the risk of OA, knee OA, hip OA, and TKA. MVMR findings revealed independent causal impacts of walking for pleasure and watching television on overall and knee OA, taking into account BMI, smoking, and education. This study suggested that light DIY and walking for pleasure were beneficial for preventing OA, and the risk of OA and TKA increased with prolonged television watching.

Abstract
Osteoarthritis (OA) is the most common form of arthritis worldwide, affecting ~500 million people, yet there are no effective treatments to halt its progression. Without any structure-modifying agents, management of OA focuses on ameliorating pain and improving function. Treatment approaches typically have modest efficacy, and many patients have contraindications to recommended pharmacological treatments. Drug development for OA is hindered by the gradual and progressive nature of the disease and the targeting of established disease in clinical trials. Additionally, new medications for OA cannot receive regulatory approval without demonstrating improvements in both structure (pathological features of OA) and symptoms (reduced pain and/or improved function). In clinical trials, people with OA show high 'placebo responses', which hamper the ability to identify new effective treatments. Placebo responses refer to the individual variability in response to placebos given in the context of clinical trials and other settings. Placebo effects refer specifically to short-lasting improvements in symptoms that occur because of physiological changes. To mitigate the effects of the placebo phenomenon, we must first understand what it is, how it manifests, how to identify placebo responders in OA trials and how these insights can be used to improve clinical trials in OA. Leveraging placebo responses and effects in clinical practice might provide additional avenues to augment symptom management of OA.

Abstract
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.

METHODS For Subgrouping and TargetEd Exercise pRogrammes for knee and hip OsteoArthritis (STEER OA), individual participant data (IPD) were sought from all published randomised controlled trials (RCTs) comparing therapeutic exercise to non-exercise controls in people with knee/hip OA. Using the Counterfactual framework, the effect of the exercise intervention and the percentage mediated through each potential mediator (muscle strength, proprioception and range of motion (ROM)) for knee OA and muscle strength for hip OA were determined. RESULTS Data from 12 of 31 RCTs of STEER OA (1407 participants) were available. Within the IPD data sets, there were generally statistically significant effects from therapeutic exercise for pain and physical function in comparison to non-exercise controls. Of all potential mediators, only the change in knee extension strength was statistically and significantly associated with the change in pain in knee OA (β -0.03 (95% CI -0.05 to -0.01), 2.3% mediated) and with physical function in knee OA (β -0.02 (95% CI -0.04 to -0.00), 2.0% mediated) and hip OA (β -0.03 (95% CI -0.07 to -0.00), no mediation). CONCLUSIONS This first IPD mediation analysis of this scale revealed that in people with knee OA, knee extension strength only mediated ±2% of the effect of therapeutic exercise on pain and physical function. ROM and proprioception did not mediate changes in outcomes, nor did knee extension strength in people with hip OA. As 98% of the effectiveness of therapeutic exercise compared with non-exercise controls remains unexplained, more needs to be done to understand the underlying mechanisms of actions.

Moderators of the effect of therapeutic exercise for knee and hip osteoarthritis: a systematic review and individual participant data meta-analysis. THE LANCET. RHEUMATOLOGY 2023; 5:e386-e400. [PMID: 38251550 DOI: 10.1016/s2665-9913(23)00122-4] [Citation(s) in RCA: 20] [Impact Index Per Article: 20.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/15/2023] [Revised: 04/08/2023] [Accepted: 04/17/2023] [Indexed: 01/23/2024]
Abstract
BACKGROUND Many international clinical guidelines recommend therapeutic exercise as a core treatment for knee and hip osteoarthritis. We aimed to identify individual patient-level moderators of the effect of therapeutic exercise for reducing pain and improving physical function in people with knee osteoarthritis, hip osteoarthritis, or both. METHODS We did a systematic review and individual participant data (IPD) meta-analysis of randomised controlled trials comparing therapeutic exercise with non-exercise controls in people with knee osteoathritis, hip osteoarthritis, or both. We searched ten databases from March 1, 2012, to Feb 25, 2019, for randomised controlled trials comparing the effects of exercise with non-exercise or other exercise controls on pain and physical function outcomes among people with knee osteoarthritis, hip osteoarthritis, or both. IPD were requested from leads of all eligible randomised controlled trials. 12 potential moderators of interest were explored to ascertain whether they were associated with short-term (12 weeks), medium-term (6 months), and long-term (12 months) effects of exercise on self-reported pain and physical function, in comparison with non-exercise controls. Overall intervention effects were also summarised. This study is prospectively registered on PROSPERO (CRD42017054049). FINDINGS Of 91 eligible randomised controlled trials that compared exercise with non-exercise controls, IPD from 31 randomised controlled trials (n=4241 participants) were included in the meta-analysis. Randomised controlled trials included participants with knee osteoarthritis (18 [58%] of 31 trials), hip osteoarthritis (six [19%]), or both (seven [23%]) and tested heterogeneous exercise interventions versus heterogeneous non-exercise controls, with variable risk of bias. Summary meta-analysis results showed that, on average, compared with non-exercise controls, therapeutic exercise reduced pain on a standardised 0-100 scale (with 100 corresponding to worst pain), with a difference of -6·36 points (95% CI -8·45 to -4·27, borrowing of strength [BoS] 10·3%, between-study variance [τ2] 21·6) in the short term, -3·77 points (-5·97 to -1·57, BoS 30·0%, τ2 14·4) in the medium term, and -3·43 points (-5·18 to -1·69, BoS 31·7%, τ2 4·5) in the long term. Therapeutic exercise also improved physical function on a standardised 0-100 scale (with 100 corresponding to worst physical function), with a difference of -4·46 points in the short term (95% CI -5·95 to -2·98, BoS 10·5%, τ2 10·1), -2·71 points in the medium term (-4·63 to -0·78, BoS 33·6%, τ2 11·9), and -3·39 points in the long term (-4·97 to -1·81, BoS 34·1%, τ2 6·4). Baseline pain and physical function moderated the effect of exercise on pain and physical function outcomes. Those with higher self-reported pain and physical function scores at baseline (ie, poorer physical function) generally benefited more than those with lower self-reported pain and physical function scores at baseline, with the evidence most certain in the short term (12 weeks). INTERPRETATION There was evidence of a small, positive overall effect of therapeutic exercise on pain and physical function compared with non-exercise controls. However, this effect is of questionable clinical importance, particularly in the medium and long term. As individuals with higher pain severity and poorer physical function at baseline benefited more than those with lower pain severity and better physical function at baseline, targeting individuals with higher levels of osteoarthritis-related pain and disability for therapeutic exercise might be of merit.

Abstract
Objective To investigate whether knee osteoarthritis (OA) related pain and function can be improved by offering enhanced physical therapist-led exercise interventions. Design Three-arm prospectively designed pragmatic randomized controlled trial. Setting General practices and National Health Service physical therapy services in England. Participants 514 adults (252 men, 262 women) aged ≥45 years with a clinical diagnosis of knee osteoarthritis (N=514). Mean Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores at baseline were 8.4 for pain and 28.1 for function. Interventions Participants were individually randomized (1:1:1 allocation) to usual physical therapy care (UC control: up to 4 sessions of advice and exercise over 12 weeks), individually tailored exercise (ITE: individualized, supervised, and progressed lower limb exercises, 6-8 sessions over 12 weeks), or targeted exercise adherence (TEA: transitioning from lower limb exercise to general physical activity, 8-10 contacts over 6 months). Main Outcome Measures Primary outcomes were pain and physical function measured by the WOMAC at 6 months. Secondary outcomes were measured at 3, 6, 9, 18, and 36 months. Results Participants receiving UC, ITE, and TEA all experienced moderate improvement in pain and function. There were no significant differences between groups at 6 months (adjusted mean differences (95% confidence intervals): pain UC vs ITE, -0.3 (-1.0 to 0.4), UC vs TEA, -0.3 (-1.0 to 0.4); function UC vs ITE, 0.5 (-1.9 to 2.9), UC vs TEA, -0.9 (-3.3 to 1.5)), or any other time-point. Conclusions Patients receiving UC experienced moderate improvement in pain and function; however, ITE and TEA did not lead to superior outcomes. Other strategies for patients with knee osteoarthritis to enhance the benefits of exercise-based physical therapy are needed.
