Surgical Robotics Technology
THINK Surgical, Inc., an innovator in the field of orthopedic surgical robots, today announced the successful first use of Medacta International’s GMK Sphere® Medially Stabilized Knee utilizing the TMINI® Miniature Robotic System by Matthew Beal, MD an Adult Reconstruction Surgeon at the Ohio State University Wexner Medical Center in Columbus, OH.
The GMK® Sphere and GMK SpheriKA knees are an innovative implant addition to THINK Surgical’s ID-HUB™ proprietary implant Data Bank used by the TMINI Miniature Robotic System. The GMK Sphere and SpheriKA® systems are the only medial Ball-in-Socket design knee systems available for use with the TMINI Robot, and the GMK Sphere knee has been shown to provide high stability throughout the entire range of motion.1, 2, 3 Good clinical results have been achieved when implanting GMK Sphere with both mechanical and kinematic alignment philosophies.4, 5 GMK SpheriKA is the latest addition to Medacta’s knee portfolio and is the first femoral component specifically optimized for the kinematic alignment technique. Both knee systems also offer a metal-sensitive option with SensiTiN™ coating and cementless applications with MectaGrip coating.
“This first case with the TMINI Robot and GMK Sphere by Dr. Beal is an exciting milestone,” said Stuart Simpson, CEO and President of THINK Surgical. “Surgical case plans utilizing Medacta’s medial stabilized knee designs and commitment to the kinematic alignment philosophy can be executed with precision using our TMINI Robotic system.”
“We’re very excited to announce the first implementation of our partnership with THINK Surgical,” said Matt Goudy, Managing Director of Medacta, USA. “This partnership enables surgeons to leverage handheld robotic technology with the GMK Sphere or GMK SpheriKA knee systems, providing the potential to enhance patient outcomes. As the only medial ball-in-socket knee system available for use with the TMINI Robot, we look forward to the results this synergy is expected to bring.”
THINK Surgical received FDA 510(k) clearance for use of the Medacta GMK Sphere and SpheriKA knee implants with the TMINI Miniature Robotic System on August 29, 2024.
