Total knee arthroplasty (TKA) has proven to be an excellent treatment for knee arthritis during the last 30 years. To optimize knee functions, surgeons and engineers are working together, on the design of the implants and instrumentation. The ultimate goal is the facilitation of the reconstruction of the natural joint line height, the three different alignment planes, the correct femoral and tibial size and finally knee anatomy and kinematics. Unicompartmental tibiofemoral and patellofemoral arthroplasty can be used if limited parts of the joint present wear. Patient Matched Technology makes preoperative analysis and understanding of the complex 3D geometry of the knee possible before surgery. Patient Specific Instruments (PSI) available as different pinning and cutting guides help with accurate positioning of the instruments matching easy-to-find surfaces in the knee, in contrast to the classic anatomical landmarks that are more difficult to find back consistently. Robotics help to increase accuracy during implantation reducing the impact of the surgeon’s own physical limitations and those of the available power tools. Further, this new technology will make it possible to design patient matched implants adapted to their individual anatomy. Disposable individualized instruments will rationalize set up times in operating rooms. The outsourcing of the surgical preoperative planning and the reflection on anatomic reference points should help to reduce the surgical time.
