LONDON, March 6, 2018 /PRNewswire/ — Smith & Nephew (LSE:SN, NYSE: SNN), the global medical technology business, today announces the full commercial release of bi-cruciate retaining JOURNEY II XR total knee arthroplasty (TKA) in the United States and Japan.
JOURNEY II XR is the next step in the evolution of total knee replacement surgery. By retaining, rather than substituting, the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL), JOURNEY II XR is designed to combine the greater patient satisfaction of a partial knee replacement with the long-term survivorship and reproducible principles of TKA1-2. JOURNEY II XR accomplishes this by eliminating the past concerns of bi-cruciate retaining knees through:
- An implant design that reflects more accurate replication of the knee anatomy3
- A robust tibial baseplate designed for optimal fixation and fatigue strength
- The application of Smith & Nephew’s VERILAST™ Technology, an advanced bearing surface designed to provide lasting survivorship4
- The introduction of enabling technologies such as NAVIO™ robotics-assisted surgery and VISIONAIRE™ patient matched adaptive guides to help deliver highly reproducible outcomes
Mike Donoghue, Senior Vice President, Global Orthopaedic Marketing said, “The JOURNEY II XR knee offers surgeons an innovative treatment option for arthritic patients who have intact and well-functioning cruciate ligaments. The retention of the cruciate ligaments may provide patients with more normal feel and stability throughout the range of motion, and may lead to a smoother recovery, improved function, and better patient satisfaction.” 3,6-8
JOURNEY II total knee system is designed to achieve normal shapes, position and motion. Smith & Nephew created this platform to empower patients to “rediscover normal” following total knee arthroplasty. The full commercial release of JOURNEY II XR follows a successful limited market release in both the United States and Japan with more than 70 surgeons in both countries implanting over 1,100 JOURNEY II XR knees during the last 18 months9. Join Smith & Nephew at the American Academy of Orthopaedic Surgeons Annual Meeting, Booth #1651 in New Orleans, LA, March 7-9 to experience the Power of Patient Satisfaction and elevate what’s possible with the JOURNEY II XR Knee system.
