Castel San Pietro, October 30, 2023 – Medacta Group SA (“Medacta”, SIX: MOVE), a Swiss company providing innovative, personalized and sustainable solutions for joint replacement, sports medicine and spine surgery, is pleased to announce the launch of GMK SpheriKA, the world’s first KA-optimized femoral component indicated for total knee replacement. GMK SpheriKA will make its global debut on November 2 at the American Association of Hip and Knee Surgeons (AAHKS) 2023 Annual Meeting.

“GMK SpheriKA reinforces Medacta’s commitment to providing surgeons with personalized solutions for each of their patients,” says Francesco Siccardi, Chief Executive Officer of Medacta International.“Working with an international team of expert orthopedic surgeons, we have introduced a product that builds on our clinically proven GMK Sphere and incorporates the foundations of Kinematic Alignment to ensure every patient receives an implant that is suitable for his or her unique anatomy.”

Medacta’s continued commitment to making a positive impact on patients requiring a total knee procedure has evolved with the development of the concept of Kinematic Alignment, which restores the original pre-arthritic alignment through anatomical resurfacing, making it ligament release is minimized and more natural knee kinematics are enabled. This approach has been shown to improve patient satisfaction compared to more traditional techniques [1-3]. In recent years, clinical studies have shown that GMK Sphere is a particularly suitable implant for kinematic alignment, with the potential to further improve patient outcomes compared to other knee designs [4-6].

Building on the legacy of the GMK Sphere’s ball-in-socket design, GMK SpheriKA offers patients an implant that potentially feels more natural and stable during daily activities, replicating the movement of the healthy knee.In addition,GMK SpheriKA provides optimized femoral coverage and patellar tracking for kinematic alignment procedures, making it the first implant on the market specifically designed for this technique.

“I am happy to offer the GMK SpheriKA to my patients,” said surgeon developer and Kinematic Alignment pioneer Stephen Howell, MD.“The implant design provides a personalized option that takes into account each patient’s unique anatomy and patellofemoral kinematics, restoring a more normal-feeling knee and quickly returning motion and daily activities.”

MyKA, Medacta’s Kinematic Alignment Platform, offers surgeons the most comprehensive solution for performing Kinematic Alignment safely and reproducibly. In addition to GMK SpheriKA, it includes special instruments and a tailor-made education program offered by the MORE Institute, supported by an international network of expert surgeons. In addition, the platform is enhanced by advanced technologies, such as a special planning protocol for the MyKnee 3D printed patient-tailored manuals and NextAR Knee, our Augmented Reality surgical application, which provides unique real-time data to efficiently supplement the surgical workflow. . Both NextAR Knee and MyKnee are part of the MySolutions Personalized Ecosystem, Medacta’s network of advanced digital solutions designed to improve patient outcomes and healthcare efficiency.
