Abstract

A blend of three copolymers of 50:50 poly(DL-lactide-co-glycolide) with inherent viscosities of 0.23, 0.58 and 1.37 dl/gm was used as the starting material of a cartilage implant. The new design's salient in vitro biodegradation characteristics were obtained and compared with those of the current design. The axial strain was calculated at the surface of the implant by normalizing the equilibrium creep value with the initial implant thickness. The Boussinesq-Papkovitch equation was used to calculate Young's modulus, and the porosity was quantified by applying the NIH Image 1.60 software to the images produced by scanning electron microscopy.
