Three-compartment knee prosthesis SCORE® II

mobile-bearing

Stability through congruency Rotating platform, mobile bearing PCL-sacrificing The femoral component design is based on a study of 1,200 knees digitised using the AMPLIVISION® navigation system. Trochlear groove is angled 6° and has a constant radius of curvature, giving the surgeon the choice of keeping the native patella or replacing it. Constant depth of intercondylar groove reduces pressure on the patella, ensures congruency with the spine of the PE insert and increases sagittal and frontal plane stability. Insert's radius of curvature matches that of the femoral component when the knee is extended. This congruency ensures stability and load distribution. The insert's spine ensures mediolateral stability during flexion. Insert and tibial baseplate can differ by up to 2 sizes thanks to the chamfer all along the bottom of the contour. The peg's cylindrical cone shape allows for self-centring and prevents the insert from separating from the baseplate during flexion. The SCORE® II offers 1 mm increment for the most used inserts. The SCORE® tibial baseplate has an anatomical rear cut-out to help match bone morphology. The contact area with the insert is highly polished, which reduces wear at the tibial baseplate/insert interface. Keel and delta wing help to stabilise baseplate in the tibia. The tibial keel is cylinder-shaped (length 35 mm) and the same for all sizes. The delta wing sizes match those of the baseplate. The SCORE® II instrumentation set can be used with Computer Assisted Surgery (AMPLIVISION®) or without Computer Assisted Surgery.
