Smith+Nephew has completed the first total knee arthroplasty (TKA) with its JOURNEY II medical dished (MD) system. The surgery was performed by NYU Langone Health hip and knee surgeon Dr. Ran Schwarzkopf.
JOURNEY II MD is now available in the U.S. for TKA. It includes a tibial insert that can offer more normal motion and stability if the PCL has been resected or isn’t in good condition. 1-5
"Adding a medial dished component to the JOURNEY II TKA portfolio is a significant development and expands the options I'm able to offer my patients,” Dr. Schwarzkopf told the press. “It allows me to optimize the kinematics for my patient's while also providing good stability in either a cruciate-retaining or cruciate-sacrificing total knee replacement procedure."
The implant features a more constraining medial side compared to standard tibial inserts. Tibial inserts promoting better knee kinematics has been a rapidly growing concept over the last few years.
"We are very excited about the launch JOURNEY II Medial Dished," said Randy Kilburn, executive VP and CM, Orthopaedic Reconstruction, Robotics and Digital for Smith+Nephew. "Our customers have expressed an interest in medial dished inserts and we are pleased to provide new treatment options that expand the clinical indications of the already successful JOURNEY II Knee System."
