Frequently Asked Questions (FAQ)
What is the difference between the PS and PS+ Tibial Bearings?
The PS (Standard) bearing offers no varus/valgus constraint and allows 15 degrees of internal/external rotation. The PS+ (PLUS Constrained) bearing provides a 2-degree varus/valgus constraint and restricts internal/external rotation to +/-2 degrees.
When is the PS+ Tibial Bearing indicated for surgical use?
The PS+ option is typically used in primary surgical situations where additional joint stability and initial constraint are required to resist rotation and varus/valgus lift-off.
What materials are the SKII™ components manufactured from?
The Femoral Condyles and Tibial Trays are made from durable Cobalt-Chromium-Molybdenum (CoCrMo) alloy, while the Tibial Bearings are manufactured from medical-grade Germany UHMWPE (Ultra-High-Molecular-Weight Polyethylene).
How does the SKII™ system accommodate different stages of bone defects?
The system features a seamless design that transitions from Normal Primary TKA to Complex Primary TKA using tibial augments and stems, and handles large central tibial defects with tibial cones and stems to reinforce prosthesis fixation.
What is the advantage of the Same Platform Design?
The Same Platform Design ensures compatibility across different components, allowing surgeons to address both standard primary and complex primary total knee arthroplasty (TKA) procedures efficiently.
Where can I obtain detailed surgical instructions for this knee system?
