Smith & Nephew presents suite of new clinical evidence at World Arthroplasty Congress in Rome

Smith & Nephew (LSE:SN, NYSE:SNN), the global medical technology business, today announces the presentation of new clinical evidence from several key studies at the World Arthroplasty Congress (WAC) in Rome.

The suite includes key clinical studies for JOURNEY II BCS, which is designed to facilitate near-normal kinematics and thereby has a positive impacting on patients’ satisfaction. A multi-centre study of 20 patients1 confirmed that the JOURNEY II BCS facilitates activity dependent knee kinematics with pronounced femoral rollback upon flexion. A second study compared 40 patients fitted with JOURNEY II BCS with 10 normal, asymptomatic knees during weight bearing motion.2 Patients receiving JOURNEY II BCS implants experienced normal-like kinematic patterns during early and late flexion demonstrating adequate replication of the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL). With over 50% of patients reporting some degree of limitation to their functional activities3 after total knee arthroplasty (TKA), the design of JOURNEY II BCS aims to restore the normal, healthy knee.

Smith & Nephew will also present the first long-term results for POLARSTEM™, its cementless stem system for primary hip replacement. These confirmed that it is associated with excellent long-term component survival and functional outcomes approximately 12 years after total hip replacement (THR).4

“In the last year Smith & Nephew has significantly increased its investment in supporting the production of clinical evidence as we know this is vital for customers looking to assess the value of innovations in the medical devices.  We are proud to publish this suite of new clinical studies at the World Arthroplasty Congress and are on track to present more than 50 pieces of evidence in 2018. We greatly value the evidence-based conversations these allow us to have with healthcare professionals.” said Vasant Padmanabhan, President of Research & Development, Smith & Nephew.

Additional studies feature the REDAPT™ revision acetabular system fully porous cup and the NAVIO™ robotics-assisted surgical system. A full list of presentation is available by visiting Smith & Nephew’s “The Power of Patient Satisfaction” booth #23 at the World Arthroplasty Congress 19-21 March 2018. Summaries of key presentations will be provided on Smith & Nephew’s Education & Evidence website: http://www.smith-nephew.com/education in the days following this year's congress.
