Three-compartment knee prosthesis SCORE®

mobile-bearingcemented or non-cemented

Stability through congruency PCL-sacrificing 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. The peg's cylindrical cone shape allows for self-centring and prevents the insert from separating from the baseplate during flexion. 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® instrumentation set can be used with Computer Assisted Surgery (AMPLIVISION®), without Computer Assisted Surgery or with patient-specific guides (i.M.A.G.E.®). This knee replacement system can be implanted using: - bone or ligament landmarks - anterior or posterior reference points. Either a 4-in-1 or 5-in-1 resection guide can be used. The 5-in-1 resection guide is available in Standard and I.M.A. versions.
