N 91-23032 ADAPTATION OF NASA TECHNOLOGY FOR THE OPTIMIZATION OF ORTHOPEDIC KNEE IMPLANTS by

NASA technology originally developed for the optimization of composite structures (engine blades) is adapted and applied to the optimization of orthopedic knee implants. A method is developed enabling the tailoring of the implant for optimal interaction with the environment of the tibia. The shape of the implant components are optimized, such that the stresses in the bone are favorably controlled to minimize bone degradation and prevent failures. A pilot tailoring system is developed and the feasibility of the concept is evaluated. The optimization system is expected to provide the means for improving knee prosthesis and individual implant tailoring for each patient.
