Target-based approach for osteoarthritis treatment

Area of Science:

• Orthopedics and Musculoskeletal Disorders
• Rheumatology
• Personalized Medicine

Background:

• Knee osteoarthritis (OA) presents a significant health challenge with no universally effective treatment or consensus on management strategies.
• The complex pathophysiology of knee OA involves intricate mechanical, inflammatory, metabolic, post-traumatic, molecular, genetic, and psychological factors, complicating treatment development.

Discussion:

• Current treatment recommendations for knee OA remain equivocal due to the multifaceted nature of the disease and varied patient responses.
• Phenotype-based patient classification, while an advancement, has proven insufficient for predicting treatment efficacy, as individuals within the same phenotype exhibit diverse responses and disease progression.

Key Insights:

• A novel approach is proposed: managing individual targets involved in OA genesis and progression, rather than treating OA as a singular entity.
• This fragmented yet individualized strategy aims to achieve personalized OA management, acknowledging the unique biological and clinical profiles of each patient.

Outlook:

• The proposed paradigm shift from disease-centric to target-centric management holds the potential for more effective and holistic patient care in knee OA.
• Further research into specific molecular, genetic, and biomechanical targets is crucial for realizing truly personalized OA treatment strategies.
