In our previous study, parameterized polynomial function was applied for describing the artificial knee joint surfaces and the results were found to be superior to the established practices. However, this polynomial function was difficult for reconstructing human knee joint surface with minute undulation. To overcome this problem, we tried an additional application of Fourier series approximation in this study. First, the global shape of objective surface was described by polynomial function. Then, minute undulation was approximated with Fourier series. Finally, two sets of approximation were combined. This surface fitting method was applied to swain knee joint surface and curvature analysis was performed.
