The most common treatment for osteoarthritis is daily oral administration of a nonsteroidal anti-inflammatory drug such as diclofenac. This daily dosage regime is often associated with severe side effects. In this study, we explored the potential of utilizing a high molecular weight cross-linked polyurethane polymer covalently linked to diclofenac (C-DCF-PU) for intra-articular administration. We aim to exploit the advantages of local drug delivery by developing an implant with improved efficacy and reduced side effects. The polymer was synthesized from a diclofenac-functionalized monomer unit in a simple one-pot reaction, followed by cross-linking. In vitro drug release studies showed zero-..
