=D I'm actually doing a project of the knee joint prosthesis, but I do not know what type of knee joint structure to choose or even start with. Please give some advice. Thanks. =)
That is a field of study that is keeping physicians, biomechanical engineers, prostheticians, and several other experts in various disciplines occupied into overtime.
I am not even close to being current, but the last that I knew of the favourites were cobalt steel and polymer, with Teflon coating as a substitute for synovial fluid. That was a long time ago, though, so I don't know what they're up to now.
