Frequently Asked Questions (FAQ)
Q1: What are the primary benefits of the SKI™ PS High Flexion Total Knee System?
A1: The system features a Wider Proximal Trochlear for excellent patellar tracking, a Cruciate Finned Keel for enhanced rotational stability, and a Rounded PS Post designed to reduce gravimetric wear by 71% compared to standard square posts.
Q2: How does the Rounded PS Post design improve joint longevity?
A2: By utilizing a rounded geometry instead of a traditional square post design, the contact stress during femoral rotation is optimized, resulting in a 71% reduction in gravimetric wear.
Q3: What materials are used in the SKI™ Knee System components?
A3: The Femoral Condyle and Tibial Tray are manufactured from high-performance Cobalt-Chromium-Molybdenum (CoCrMo) alloy. The Tibial Bearing is made from premium Germany UHMWPE (Ultra-High-Molecular-Weight Polyethylene).
Q4: Does the system accommodate different patient anatomies?
A4: Yes, the SKI™ Femoral Condyle features a wider proximal trochlear that ensures excellent patellar tracking regardless of the patient's specific Q-angle, and components are available in multiple sized specifications (1# through 9#).
Q5: How does the Extended Trochlear Groove support deep flexion?
A5: The extended trochlear groove provides continuous support for the patella during deep flexion movements, easing the stress on the quadriceps tendon and improving overall joint kinematics.
Q6: Where can I find detailed surgical procedures for the SKI™ System?
A6: You can download the complete "JUST MED Surgical Technique Manual for the SKI PS High Flexion Total Knee System" PDF directly from our Technology Education section above.
