Abstract This study was undertaken to glean preliminary information on the role of triphasic ceramic coated hydroxyapatite (HASi) and biphasic (alpha-tricalcium phosphate and hydroxyapatite based) calcium phosphate (BCP) for the development of osteochondral constructs. The proposed constructs were tested for performance in vitro with rabbit adipose-derived mesenchymal stem cells (RADMSCs) and further analysed in vivo in a lapine model for osteochondral defect amelioration. Desirable scaffolding architecture ensuring favourable conditions for cell attachment, nutrient exchange and neo-tissue organization was achieved by the synthesis of porous ceramic blocks and characterizations were carried out using x-ray diffraction and Fourier transform infrared spectroscopy. The cytocompatibility of the scaffold-cell combination product was evaluated using microscopy techniques that proved the scaffold to be non-cytotoxic and favourable for cell growth and proliferation. Short-term implantation studies were conducted with bare cylindrical HASi and BCP scaffolds, press fit deep into the bony bed of the median femoral condyles of the rabbit, which resulted in favourable specific in vivo response of de novo cartilage-like cells on the surface and sub-surface bony trabeculae. The generated pilot data will help to assess the severity of proposed procedures before embarking on scaled-up efforts.
