Pain science education and exercise interventions for people with knee or hip osteoarthritis: a systematic review, content and meta-analysis.
Synthesis in BMC musculoskeletal disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPhysical activity can improve pain and wellbeing for people with osteoarthritis, including those awaiting joint replacement, for whom physical activity can improve post-operative recovery. However, people with osteoarthritis report pain as a barrier to exercise. Pain Science Education (PSE) can reframe this by addressing beliefs about pain that impact exercise. This systematic review aimed to map the content of PSE interventions for people with osteoarthritis, and evaluate the effectiveness of intervention components.
methodsThis review synthesised evidence on PSE and exercise interventions for people with knee or hip osteoarthritis, including those awaiting joint replacement. Databases were searched for RCTs and non-randomised studies, from inception to 1 August 2024 (MEDLINE/PsycINFO/EMBASE/PEDro). Risk of bias was assessed (RoB 2/ROBINS-I). Intervention content was analysed using content analysis. Outcomes were analysed quantitatively, including a component network meta-analysis (cNMA) of RCTs, presented parallel to non-randomised study results. Treatment effects were evaluated against PSE intervention components to understand which components impacted outcomes (pain/physical functioning/catastrophizing/kinesiophobia/self-efficacy).
resultsTwelve reports of 10 interventions (20-103 participants per study) were included. Content analysis identified six domains: introductory topics, acute pain mechanisms, chronic pain mechanisms, factors that sustain pain, multidisciplinary education, and exercise components. cNMA: PSE had little-to-no effect on pain and physical functioning, with beneficial effects on catastrophizing, kinesiophobia and self-efficacy.
conclusionsThis review highlights potential effectiveness of PSE intervention components for improving psychological outcomes for people with osteoarthritis. PSE may act as a mechanism of action for exercise interventions, and is less successful delivered standalone. PSE should be delivered using relatable examples and tailored exercises to ensure accessibility. Findings should be interpreted cautiously due to the small number of heterogeneous studies.
