To assess the impact of intraarticular hyaluronic acid (HA) on clinical outcome and on volumetric and T2 relaxation based changes of articular cartilage in mild to moderate osteoarthritis (OA) of the knee joint.


Patients with moderate OA of the knee [Kellgren-Lawrence II] were recruited for a 6-months prospective, randomized clinical trial evaluating the effect of HA on articular cartilage morphology and composition. Clinical examinations and MRI were performed at baseline, and after 6, 12 and 24 weeks. Cartilage volume, thickness and surface area were determined in cartilage plates and subregions were defined using proprietary software. MRI was performed on a 1.5 Tesla scanner; morphological evaluation was performed using 3D T1-w FLASH Waterexcitation (WE) sequences and T2 maps were calculated from a multiecho, spin-echo sequence.
