Intelligent Knee Trial to Support Balancing of Triathlon Knee System
MAHWAH, NJ, and SUNRISE, FL, (August 17, 2011) – Stryker Corporation’s Orthopaedics Division and OrthoSensor, Inc., a leader in intelligent orthopedics, today announced an agreement in which OrthoSensor will provide the OrthoSensor™ KneeTrial, designed for use with Stryker’s Triathlon Knee System. The OrthoSensor Knee Trial is an intelligent trial that provides quantitative, intra-operative feedback to surgeons to improve joint balance during total knee arthroplasty.
The OrthoSensor Knee Trial has embedded micro-electronics and sensors in single-use trial inserts, delivering data to improve the final ligament balance and patients’ specific joint kinematics. The sensor wirelessly transmits this key information to a graphic display of real-time feedback, enabling the surgeon to visualize and quantify joint loading and balance.With this evidence, the surgeon can make an informed choice to modify implant positioning and adjust soft tissue for better balance through a full range of motion.
“The single radius design philosophy of Stryker knees is a perfect complement to OrthoSensor’s innovative technology,” said Doug Leach, vice president of global research and development, knee reconstruction at Stryker Orthopaedics. “The Triathlon Knee System is uniquely suited to the finer elements of ligament balancing and being able to take advantage of this new offering provides us with the opportunity to combine our advanced orthopaedic implant technology with cutting-edge sensor technology.”
Stryker’s Triathlon Knee System offers patients the potential for improved motion1 and better fit2, and remains classified as the knee system that outperforms the most frequently used brands in terms of revision rates as identified in the National Joint Registry of England and Wales.3,4
“By integrating sensors into the surgical suite, OrthoSensor is leading the evolution in intelligent orthopaedic surgery and we are pleased to collaborate with Stryker Orthopaedics to turn this new field into a reality,” said Jay Pierce, CEO of OrthoSensor. “Until now, surgeons have lacked quantifiable data about joint kinematics and their decisions varied based on individual judgment, experience and skill set. OrthoSensor’s intelligent surgical device will provide surgeons, hospitals and health plans access to real-time data to make evidence-based decisions with the goal of improving patient outcomes and lower costs related to treating musculoskeletal disease.”
