Mesenchymal stem cell-based therapy for osteoarthritis: a systematic review and meta-analysis of clinical outcomes and functional recovery

Intra-articular MSC injection is an effective treatment for osteoarthritis, providing significant and durable improvements in pain relief, functional recovery, and activity levels up to 24 months post-treatment. The time-dependent nature of clinical benefits suggests a potential disease-modifying mechanism of action. MSC therapy represents a promising regenerative approach for OA management that warrants further investigation in large-scale trials.
