Frequently Asked Questions
What are the key design features of the SKI PS High Flexion Total Knee System?
The SKI PS system incorporates several key advancements: a wider proximal trochlear for better patellar tracking, a cruciate finned keel for rotational stability, a rounded PS post to minimize wear, and an extended, deep trochlear groove to relieve patellar forces during deep flexion.
How does the Rounded PS Post design reduce wear?
Compared to traditional square post design geometries, the Rounded PS Post reduces gravimetric wear in femoral rotation by up to 71%, significantly extending the longevity of the implant.
What materials are used in the construction of the system?
The Femoral Condyle and Tibial Tray are constructed from CoCrMo (Cobalt-Chromium-Molybdenum) alloy for high durability and strength. The Tibial Bearing is made from premium Germany UHMWPE (Ultra-High-Molecular-Weight Polyethylene) to offer low friction and excellent wear resistance.
What size options are available for the Tibial Tray and Tibial Bearing?
The Tibial Tray comes in sizes 1# through 7# with A/P dimensions ranging from 38mm to 53mm. The Tibial Bearing is available in thicknesses of 8mm, 10mm, 12mm, and 14mm, specifically designed to match and fit different Tibial Tray sizes.
How does the system support patellar tracking?
Through its wider proximal trochlear and deep, extended trochlear groove, the system ensures stable and consistent patellar tracking across the entire range of motion, regardless of the patient's individual Q-angle.
