Abstract
The present invention relates to a method of manufacture of an interconnected porous non-biodegradable polymer implant suitable for implantation into a mammal for the treatment, repair or replacement of defects or injury in musculoskeletal tissue, wherein the mechanical properties of the implant can be controlled by varying the concentration of the non-biodegradable polymer and/or varying the duration and number of freeze-thaw cycles and the interconnected porous non-biodegradable polymer implant has sufficient percent porosity and pore diameter to facilitate integration of cells and attachment within the mammal via ingrowth of surrounding tissue. The present invention also relates to an implant manufactured by the method.
