Recent Advances in Therapeutic Approaches for Knee Osteoarthritis: a Narrative Review.

Knee osteoarthritis (KOA) is a progressive and chronic musculoskeletal condition that continues to be the leading cause of disability worldwide. Conventional treatment approaches for the management of KOA largely focus on symptom alleviation rather than halting or reversing disease progression. However, recent advancements have highlighted the integrated interplay of mechanical stress, inflammation, cellular senescence, and chondrocyte dysfunction in the progression of KOA, in turn prompting new therapeutic strategies. Therefore, emerging interventions such as regenerative medicine, gene therapy, senolytic, platelet-rich plasma (PRP), disease-modifying osteoarthritis drugs (DMODs), and biologics have broadened the therapeutic options. Additionally, natural compounds demonstrated potential in KOA treatment with promising chondroprotective and anti-inflammatory effects. Moreover, digital technologies and clinical and molecular phenotyping enhanced early diagnosis, monitoring, and personalized management of the disease. Therefore, the current narrative review focuses on the molecular insights, clinical outcomes and prospects for the rapidly evolving landscape of current and emerging treatment approaches for the management of knee osteoarthritis (KOA).
