Knee Joint Implants

Since the first knee joint replacement nearly 50 years ago, continuous improvements in devices and surgical techniques have led to numerous breakthroughs in technology. The large number of different types of knee endoprosthetics with regard to fitting type, fixation, bearing couple, design and degree of coupling require defined test series for the approval process. Facilities in Orthoteck lab enable us to conduct these test with high quality.
