Title

Hybrid Scaffolds of Hyaluronic Acid and Collagen Loaded with Prednisolone: an Interesting System for Osteoarthritis

Pages

  11-19

Abstract

 Purpose: Cartilage regeneration by using polymeric Scaffolds is a new option for treatment of osteoarthritis. A good Scaffold for tissue engineering should copy the characteristics of natural extracellular matrix. The purpose of this study was to make a dosage form with proper reliability and stability for cartilage repair. Methods: Hybrid Scaffolds containing different ratios of Hyaluronic acid (HA) and Collagen were prepared and loaded with prednisolone as anti-inflammatory agent. Two different dosage forms (lyophilized Implantable disk and Thermo-sensitive gels) were examined. A Scaffold of cross-linked HA was used as control. Different characterization tests were considered including differential scanning calorimetry (DSC), scanning electron microscopy, mechanical evaluations, and drug release. Results: The physical and chemical performance of hybrid-Scaffolds was better than HA Scaffold. Increasing the concentration of HA and Collagen improved the physical and chemical characteristics. Regarding the mechanical properties of the hybrid Scaffold, the pore size was 20-200μ m, compressive modulus was 54. 77± 0. 31 kPa, more than 1200% water uptake was observed after 4 days, gelation temperature was 32± 0. 16° C, gelation time was 2. 4± 0. 1 min, and drug release was controlled for 5 days by Higuchi release kinetic model. Conclusion: It seems that this porous hybrid Scaffold could be a suitable choice in Cartilage regeneration as well as a controlled-release system for delivery of prednisolone in osteoarthritis.
