Non-Pharmacological Interventions for Knee Osteoarthritis Management

Knee osteoarthritis is a leading cause of pain and functional limitation worldwide. Management paradigms increasingly emphasise non-pharmacological approaches to complement or reduce reliance on medication and delay surgical intervention. Core strategies include structured exercise programmes (aerobic, strength, neuromuscular and balance training), weight management and physiotherapy modalities (manual therapy, biomechanically-informed exercises and hydrotherapy). Mind–body practices such as Tai Chi and Qigong have been shown to modulate pain perception and psychological well-being. Self-management education, delivered in person or via digital platforms, aims to empower patients with joint protection techniques, pacing strategies and behavioural skills for long-term adherence. These interventions act through mechanical, inflammatory and central pain-modulating pathways, with demonstrated benefits for pain reduction, improved mobility and enhanced quality of life. Integration of tailored regimens, patient preference and accessibility considerations underpins a personalised approach that addresses the global burden of knee osteoarthritis.

Research from Nature Portfolio

Recent meta-analyses synthesising randomised controlled trials have compared the efficacy of various non-pharmacological regimens on pain and depressive symptoms in osteoarthritis populations. Movement meditation practices and multimodal programmes that combine mind–body elements with psychological support exhibit moderate effect sizes for pain relief and small to moderate improvements in mood, outperforming aerobic or resistance training alone. These studies emphasise consistency in outcome measurement and the importance of subgroup analyses to identify responders. Emerging recommendations call for longer follow-up periods to evaluate the sustainability of benefits and the incorporation of digital monitoring tools to enhance data on adherence and functional outcomes.
