When performance is comparable, simplicity matters. Modern Universal vs. Asymmetric design:
• Lower patellar tilt
• Similar patient-reported outcomes
• No significant difference in revisions
• Fewer instrument trays
Clinical performance - simplified.

The study that changed the conversation about universal knees.

Researchers evaluated modern symmetrical vs. asymmetrical TKA designs in a head-to-head retrospective review.

The Setup: • 225 patients (246 knees) - Modern Universal (Klassic®) • 235 patients (236 knees) - Asymmetric (Vanguard) • Minimum 1-year follow-up • Radiographic and clinical outcomes

The Results:
📉 Patellar Tilt: Modern Universal showed SIGNIFICANTLY less patellar tilt than the asymmetric design (P < 0.0001)

📊 Patient-Reported Outcomes: • PROMIS Physical Function: 43.5 vs 41.1 (ns) • PROMIS Physical Health: 48.2 vs 46.7 (ns)
• PROMIS Mental Health: 53.3 vs 51.8 (ns) • KOOS JR: 74.5 vs 78.4 (ns)

🔧 Complications: • Manipulation under anesthesia: 6.1% vs 4.2% (ns) • Reoperation: 3.7% vs 3.0% (ns) • Infection: 1.7% vs 1.7% (ns)
Translation: Equivalent safety profile.

The Conclusion: "The symmetrical femoral design demonstrated similar PROs and outcomes to an asymmetrical design. Despite some concern that patellar tracking could be worse in a symmetrical implant, the modern symmetrical TKA design demonstrated less patellar tilt and overall appears to perform clinically similarly to an asymmetric anatomic design."

What this means: Universal geometry + modern features = clinical performance that meets or exceeds asymmetric designs.

The breakthrough that changed everything: Our patented Double Q-Angle design. Here's the engineering insight that makes the Modern Universal Femur work:

🔬 The Problem to Solve: In early flexion (0-30°), the patella needs lateral guidance to track smoothly into the trochlear groove. With their straight and narrow trochlear designs, traditional universal knees did not provide this smooth transition.

🔧 The Innovation: We created a modern, symmetrical 9° Q-angle on BOTH sides of the trochlear groove.

Why this works: The patella experiences forces pushing it laterally, so it only engages ONE side of the femoral component during early flexion • The medial side doesn't matter during this critical tracking phase • By putting a 9° Q-angle on both sides, we guide the patella with natural kinematics, whether it's a left or right knee.

The result: Natural patellar tracking in universal geometry.
This single design innovation allowed us to combine modern clinical performance with universal efficiency—without compromise.

The Evidence Is In
Through direct comparisons, in vivo analysis, and 10-year follow-up, the Modern Universal Femur demonstrates:
• Statistically significant improvements in patellar tracking
• Natural rollback and axial rotation
• Strong long-term survivorship

Modern symmetrical design. Clinically validated.
