Kalamazoo, Michigan - May 24, 2011 - Stryker Orthopaedics, a division of Stryker Corporation (NYSE:SYK), today announced that its ShapeMatch Cutting Guides have been granted 510(k) market clearance by the U.S. Food and Drug Administration for use with the company's Triathlon Total Knee System. The single-use ShapeMatch Cutting Guides are designed and manufactured from patient-specific 3D imaging data that is derived from MRI or CT scans.
ShapeMatch Technology utilizes proprietary 3D imaging software to develop a customized pre-operative surgical plan for each patient. Upon surgeon review and approval, this plan is used to develop cutting guides for the individual patient. ShapeMatch Technology is only available for use with Stryker's Triathlon Knee System, which has demonstrated the best performance among the most frequently used brands of total knee implants as measured by revision rates in the National Joint Registry of England and Wales.(1,2)
Long-term demand for total knee surgery in the U.S. has been projected to continue increasing from 0.5 million procedures in 2005 to 3.48 million procedures in 2030.(3) The ability to contain costs and increase non-operative time efficiencies is important in meeting the demand for total knee surgery well into the future.
"We are excited to offer the Triathlon CustomFit Knee® with ShapeMatch Technology as a complement to our clinically successful Triathlon knee system," said Mike Mogul, Group President, Stryker Orthopaedics. "Achieving this clearance is an important milestone for the OtisMed business unit, and it demonstrates our commitment to bringing new, innovative technologies to market that have the potential to improve surgical and operating room efficiencies."
This technology has the potential to positively impact hospital costs associated with various stages of the patient care continuum during knee surgery. A study has shown that a reduction in instrumentation may provide a shorter procedural time(4) which may increase the potential capacity for additional procedures per day.(4,10)
