Currently technology uses Hip and Knee replacement prostheses that are generally made of Titanium alloys or from Cobalt Chromium alloys. This has the advantage of having biocompatibility with the human body, but problems arise from the dissimilarity of stiffness between bone and implant due to the high stiffness of the implant material compared to bone causing unnatural levels of stresses in the adjacent bone leading to bone remodeling and resorption (bone loss) and eventually cause loosening of the implant and failure of the join function. The reduction of stiffness of the prosthesis has been documented to reduce the stress levels in the adjacent bone and produce favorable stress levels.
