Non-surgical management of knee osteoarthritis: a stepped conservative care paradigm for early-stage disease and high-risk populations

Abstract

Knee osteoarthritis (KOA) is a leading cause of chronic pain and physical disability in the aging global population, placing an immense burden on healthcare systems. Despite its rising incidence, clinical practice and research remain disproportionately focused on late-stage joint replacement, neglecting early-stage preventive and conservative care for high-risk individuals. To address this gap, this narrative review searched major databases including PubMed/MEDLINE, Embase, Web of Science, and the Cochrane Library for clinical guidelines, high-quality systematic reviews, and randomized controlled trials focusing on non-surgical interventions for early KOA and high-risk populations. Search terms included “early knee osteoarthritis,” “non-surgical treatment,” “exercise therapy,” and “weight management”. Literature analysis demonstrates that a structured, “lifelong, stepped” non-surgical paradigm yields significant clinical efficacy. Specifically, combining dietary weight loss with physical exercise optimally reduces mechanical joint loading and systemic inflammatory markers; targeted muscle strengthening, alongside mind-body exercises like Tai Chi or yoga, improves the joint microenvironment and neuromuscular control; biomechanical orthoses and physical therapies offer substantial short-term pain relief; and topical or systemic NSAIDs combined with intra-articular injections effectively manage refractory acute symptoms. Crucially, continuous clinical supervision and structured patient education are vital for enhancing long-term treatment adherence and delaying radiological disease progression. Ultimately, implementing early, proactive non-surgical interventions, grounded in patient education and integrating weight management, targeted exercise, and multimodal stepped therapies, effectively alleviates pain, restores physical function, and delays or entirely prevents the need for future joint replacement.
