Frequently Asked Questions
What are the differences between the Standard PS and PS+ Tibial Bearings?
The Standard PS bearing offers 15 degrees of internal/external rotation with no varus/valgus constraint. The PS+ (PLUS) bearing features a 2-degree varus/valgus constraint and +/-2 degrees of internal/external rotation, designed for cases requiring enhanced stability.
When is the PS+ Tibial Bearing indicated for primary Total Knee Arthroplasty (TKA)?
The PS+ bearing is utilized in primary TKA situations when more initial stability and constraint are desired to effectively resist rotation and varus/valgus lift-off.
How does the SKII High Flexion System handle bone defects?
The system uses a seamless, same-platform design with multiple options: stem extensions for optimal stress distribution, tibial augments for varying shapes of defects, and tibial cones to strengthen prosthesis fixation in large central defects.
What materials are used in the implants?
The SKII Femoral Condyle and Tibial Tray are made of high-strength Cobalt-Chromium-Molybdenum alloy (CoCrMo). The Tibial Bearings (both standard and constrained) are manufactured using high-durability Germany UHMWPE.
What is the benefit of the Same Platform Design?
The Same Platform Design ensures that the components meet the requirements of both primary and complex primary Total Knee Arthroplasty (TKA), simplifying surgical planning and offering intraoperative flexibility.
