Application of Autologous Stem Cells From Adipose Tissue in the Regeneration of Knee Joint Cartilage

This randomized, controlled clinical trial will evaluate the safety and effectiveness of autologous adipose-derived stromal vascular fraction (SVF) therapy in patients with knee osteoarthritis (OA) grades II-IV, compared with standard chondroprotective (CP) treatment. The study will enroll male and female patients and follow them for 12 months, assessing pain (VAS), function (WOMAC, KOOS, SF-36), radiologic progression, and safety (adverse events). The trial aims to determine whether SVF therapy provides superior clinical outcomes and to inform evidence-based recommendations for OA management in the Serbian population.
