ABSTRACT:
This invention provides molded, biodegradable porous polymeric implant materials having a pore size distribution throughout the material which is substantially uniform. These materials can be molded into implants of any desired size and shape without loss of uniformity of pore size distribution. The implants are useful as biodegradable scaffolds for cell growth in healing of tissue defects. When manufactured to have an aspect ratio greater than about 3, the implants can be further hand-shaped to fit the defect into which they are placed and the desired shape for the regrown tissue.
