Instrumentation • A single easy-to-use surgical instrumentation system provides both intramedullary and extramedullary options for the surgeon. Design • A single radius femoral design for better wear properties. • MicroSeal technology seals out joint fluid and minimizes ® micromotion within tibial tray. • Porous Plasma sprayed for micro-fixation. Versatility •The system offers a range of femoral and tibial component sizes that are interchangeable. This product is approved for cement use only in the US Symmetric ™ Instrumentation Uni Knee System A single set of easy-to-use instruments allows for both an intramedullary and extramedullary alignment. Intramedullary Tibial Cutting Guides Extramedullary Distal Femoral Cutting Guides Intramedullary • Intramedullary approach aligns with medullary canal of the femur Extramedullary • Extramedullary aligns with tibial cut Posterior Cutting Guide • Matched resection • Aligns with the distal femoral cut Trialing • Simple and easy trialing Symmetric ™ A Unique Choice for the Active Uni Knee System Single Radius Design • The Symmetric Uni Knee is designed with a single radius in ™ the sagittal and coronal planes, optimizing surface contact. Symmetric ™ Uni Knee System A Unique Choice for the Active Mechanical & Microporous Fixation •Excellent mechanical and microporous fixation is achieved with the backside plasma porous spray. • The Cross-Fin on the backside of the femoral component and the fin on the tibial tray provide excellent long-term fixation. Plasma sprayed porous coating for reliable fixation This implant is approved for cemented use only in the US and this feature enhances cement fixation to the implant Symmetric ™ Uni Knee System A Unique Choice for the Active MicroSeal Interface ® • The MicroSeal interface achieves a water tight seal that ® protects the screw interface from joint fluid, while minimizing micromotion within the tibial tray. Cross-sectional view of the MicroSeal locking mechanism Cross-section of the anterior-posterior center The MicroSeal ® seals out joint fluid and minimizes micromotion Locking tab slides into matching slot for rigid fixation MicroSeal® ® • MicroSeal seals out joint fluid to protect against screw-hole osteolysis • MicroSeal deforms elastically, sealing and stabilizing liner within the tray ® • Locking and sealing features tighten as the liner warms up and absorbs fluid Symmetric ™ Uni Knee System A Unique Choice for the Active The Symmetric™ Uni Knee system offers a range of femoral and tibial component sizes to optimize fit for each patient. • Five available sizes: Sz 1-5 (Femoral & Tibial) • Five available tibial insert thicknesses: • 8mm • 10mm • 12mm • 14mm • 16mm Symmetric ™ Ordering Information Uni Knee System Symmetric Uni Femoral Knee Symmetric Uni Tibial Tray Part No. Size Part No. Size WZ-1-1001 WZ-1-1002 WZ-1-1003 WZ-1-1004 WZ-1-1005 1 2 3 4 5 WZ-1-1011 WZ-1-1012 WZ-1-1013 WZ-1-1014 WZ-1-1015 1 2 3 4 5 Symmetric Uni Tibial Poly Insert Size 1 Size 2 Size 3 Part No. Thickness Part No. Thickness Part No. Thickness WZ-1-1041 WZ-1-1021 WZ-1-1022 WZ-1-1023 WZ-1-1024 8 mm 10 mm 12 mm 14 mm 16 mm WZ-1-1042 WZ-1-1025 WZ-1-1026 WZ-1-1027 WZ-1-1028 8 mm 10 mm 12 mm 14 mm 16 mm WZ-1-1043 WZ-1-1029 WZ-1-1030 WZ-1-1031 WZ-1-1032 8 mm 10 mm 12 mm 14 mm 16 mm Size 4 Size 5 Signal Medical Corporation Part No. Thickness Part No. Thickness WZ-1-1044 WZ-1-1033 WZ-1-1034 WZ-1-1035 WZ-1-1036 8 mm 10 mm 12 mm 14 mm 16 mm WZ-1-1041 WZ-1-1021 WZ-1-1022 WZ-1-1023 WZ-1-1024 8 mm 10 mm 12 mm 14 mm 16 mm 1000 Des Peres Rd.
