No placental MSC or chondrocyte product for hip OA has FDA approval as a disease-modifying therapy. Investigational products have been used under clinical-trial exemptions. The EU has not formally approved any such product through EMA marketing authorisation, though some operate under ATMP or medical-device pathways with national regulatory flexibility.
Hip osteoarthritis (OA) develops when protective cartilage lining the femoral head and acetabulum undergoes progressive degradation—triggered by mechanical wear, inflammation, prior injury, or metabolic dysfunction—exposing the underlying bone. Cartilage lesions enlarge, bone spurs form, and synovial fluid (joint lubricant) becomes inflamed. Pain, stiffness, and loss of range of motion ensue, eventually limiting walking and activities of daily living. Cell therapy in hip OA leverages placental MSCs, engineered chondrocytes, and exosomes to deliver anti-inflammatory and cartilage-regenerative signals directly into the joint. Intra-articular injection (into the joint space) positions cells to interact with damaged cartilage surfaces, synovial tissue, and local immune cells, potentially slowing degeneration or promoting cartilage matrix repair.
