Graph 1 2 Percent reporting no difficulty Graph 2 3 Sports activity Control subjects carrying heavy objects golf racquet sports dancing Today’s fastest growing segment of knee replacement patients is seeking a return to a more active lifestyle.1 Traditional knee replacement options don’t meet the need for higher functionality, improved motion or long-term durability.2,3,4,5 Most significantly, these traditional systems fall short in providing a return to a normal pattern of motion. Lack of motion, both selection and kinematics, can mean less satisfaction for patients who are unable to...

PHYSIOLOGICAL MATCHING™ Technology through function, motion and durability JOURNEY II CR Knee System with PHYSIOLOGICAL MATCHING Conventional TKA For orthopaedic surgeons seeking treatment solutions beyond traditional knee replacements, the JOURNEY™ II Cruciate Retaining Knee has been engineered to empower patients with a renewed right to an active lifestyle by breaking through traditional knee replacement barriers and delivers Function, Motion and Durability through PHYSIOLOGICAL MATCHING Technology

Function • natomic, articular surfaces are designed to restore A native anatomy and yield a normal anatomic A/P position throughout the range of motion. Lachman test JOURNEY™ TKA patients • Anterior stability is provided by a high posterior medial lip which mimics ACL function in full extension and early gait. Increased stability through proper AP position and reduction in paradoxical motion Mid-line Sulcus • rovides a proper femoro-tibial A/P position yielding a P virtual elimination of paradoxical motion, anterior sliding of the femur during flexion.6-13 Posterior Medial Lip/Horn

Strength • ore normal muscle firing patterns are expected due M to the proper A/P positioning, thereby helping to prevent muscle fatigue during activities of daily living. • estoration of both the anatomic A/P alignment and the R normal kinematic patterns of the knee should produce more normal neuromuscular firing patterns throughout the range of motion—as demonstrated in the original JOURNEY™ BCS design.10, 15 Satisfaction (Proprioception) • mproving patients’ ease of activities of daily living can I be expected due to the anticipated improvements of strength and stability • estoration of...

Motion Tibiofemoral (TF) kinematics The kinematic patterns of the femur and tibia of a knee design have a direct impact on patients' reported levels of satisfaction with the outcomes of their knee replacements.’9, 20 Extension • Femur internally rotated to achieve a natural anatomic screw-home position • Minimal posterior femoral overhang in the sagittal plane (Proper A/P position) Mid-flexion • Femur external rotation to maximize quadriceps mechanism efficiency • Virtual elimination of paradoxical motion to prevent mid-flexion instability Deep flexion • Femur remains externally rotated to...

Durability Combining the award-winning materials of OXINIUM™ Oxidized Zirconium and highly cross-linked polyethylene (XLPE), Smith & Nephew was able to create VERILAST™ Technology, a highly urable d and long-lasting material combination.Using this technology, JOURNEY™ II TKA is designed to match the same high standards for wear performance. Graph 3 VERILAST Technology vs Conventional Technology 45 43.40 OXINIUM Technology on XLPE Mean volumetric wear rates (+/- std. dev.) of CoCr against conventional polyethylene (CPE), CoCr against crosslinked polyethylene (XLPE) and OXINIUM against XLPE...

3D surface profiles of Oxidized Zirconium and Cobalt-Chromium femoral components Wear • XINIUM™ Oxidized Zirconium is an advanced bearing O material that combines the strength of metal with the wear resistance of ceramics • OXINIUM Technology is 4,900 times more resistant to abrasion than CoCr 38 • XINIUM Technology is more than twice as hard as O CoCr (Graph 4) 39 Metal Sensitivity e understand that no measurable nickel content is W of immeasurable benefit to nickel-sensitive patients • XINIUM Oxidized Zirconium, exclusively from O Smith & Nephew, addresses the needs of nickelsensitive...

Innovating for the lifecycle Following on a rich history of partial knee arthroplasty and success of the JOURNEY™ BCS design - which showed recovery of normal patterns of motion and high gains in flexion 6-13, 21 27-28 - Smith & Nephew has created a seamless, next generation family of partial and primary knee designs intended to restore patients’ level of function, motion and durability. 1972 Richards Manufacturing Company Marmor Uni Richards Manufacturing collaborate with Dr. Leonard Marmor to commercially produce the first unicondylar knee on the market. 2006 JOURNEY PFJ -The JOURNEY PFJ...

2009 VISIONAIRE™ Patient Matched Instrumentation In 2009 Smith & Nephew globally launched the foundation of its patient specific solutions, VISIONAIRE Patient Matched Cutting blocks. Smith & Nephew was the first company to launch patient matched technology developed and manufactured completely in house. 2007 PLUS Orthopedics Smith & Nephew purchased the Swiss company PLUS Orthopedics. This added the PLUS SOLUTION knee family to the portfolio: TC-PLUS™ PRIMARY, TC-PLUS REVISION, and RT-PLUS™ REVISION. The PLUS Knee family is developed and manufactured in Switzerland and offers a seamless...
