Biomechanics of the knee joint, as they relate to arthroplasty

We now have 45 years in the modern age of knee replacement, with many lessons learned to-date, and repeating mistakes can now be avoided with just a fundamental understanding of the available published data on biomechanics and motion of the knee joint. To-date most implant designers have settled upon an averaging approach to the design of implant systems. We have now entered into an age where it is possible to customize implants for each individual patient yet respect all of the hard learned lessons of the past 45 years.
