1 U2 TM Knee System

2 Consistency in U2 Knee System over Time Share the same femoral profile of all types allow inter-changibility Uniform AP/ML dimensions in all tibial components enhance intraoperative flexibility Femoral Component Polyethylene insert Tibial Tray CR Cemented XUC CMA CR MBC MBC

4 Keep Bone Preservation in Mind 9 mm 9 mm Bone preserving 9mm resection in both distal and posterior condyles Fully interchangeable among all sizes with the consistent 18mm intercondylar width Limited intercondylar bone removal together with round shaped corner avoid the risk of intercondylar fracture Posterior slope Horizontal tibial resection surgical technique with built in 5 tibial slope

7 Optimized Freedom, Better Satisfactory flexion without implant impingement Proven by A matched round to round tibial post and box contact, eliminate impact and wear 15.5 mm Jumping Height A refined Cam/Post mechanism minimizes the risk of dislocation and prosthetic loosening

8 The Articulating Geometries Portfolio The U2 knee system offers a wide variety of insert geometries based on different clinical demands. Ultracongruent XUC - XPE Cruciate Retaining - Traditional PE CR - XPE

9 PSA Revision - Traditional PE Posterior sacrificed - Traditional PE PS - XPE Mobile Bearing MBC - Traditional PE 10 United XPE Technology Wear Resistance of United Highly Cross-linked PE (XPE) versus Traditional UHMWPE Wear (mg/million cycles) % 0 Traditional UHMWPE XPE* * Internal document in UOC

10 Modular Design Allow Augment and Stem for Encountered Bone Deficiencies U2 TM Knee Baseplate Unilateral titanium augments in 5 or 10mm thickness with screw fixation The 10-years clinical proved design The roughen texture of the recessed undersurfaces ensure an ideal cement fixation

11 CMA TM Cemented Modular Augmentable Baseplate Distal end sealed with pre-assembled plug Design without through hole avoids potential backside wear 30mm stem made of titanium alloy to enhance stability

12 Utilizing Femur Congruency in Both Fixed and Mobiled Designs U2 TM An Alternative Option to Balance the Knee Accommodates with CR femoral component and the PCL sacrifized surgical technique allows more bone preservation Up to 12.5mm prominent anterior lip and a more conforming articulating surface providing better stability The use of highly cross-linked UHMWPE reinforces insert longevity Mean >150 of flexion without implant impingement One up / one down size paring freedom Size Paring Insert #0 Baseplate #0 Femoral Component

13 U2 MBC TM Seeking for Better Longevity Accommodate with CR femoral component allows more bone preservation Sugical freedom: PCL either retained or sacrified The pure axial rotating design based on biomechanical principles proven over decades of clinical usage Central stopper enhances joint M/L stability and also allows 4.5 degrees hyperextension Highly mirror-polished platform minimize backside wear Size Paring Baseplate #0 Femoral Component

14 Defined a More Secured Stability with More Choices PSA TM Revision System A More Secured Stability Enhanced locking mechanism prevent all the locking screws from risk of backing out *petent pending Tibia Trays Accommodate All U2 Knee Femoral Components
