Personalized Knee Replacement Procedure Performed at The Orthopaedic Surgery Center at Orthopaedic Associates of Wisconsin Has Power to Return Patients to Daily Activities Faster
Dr. Mick Kelly, joint replacement surgeon at Orthopaedic Associates of Wisconsin, completed the first Total Knee Arthroplasty (TKA) surgery utilizing Medacta’s GMK SpheriKA at The Orthopaedic Surgery Center in Pewaukee, WI. The GMK SpheriKA Knee is the world’s first kinematic alignment (KA) optimized femoral component indicated for total knee replacement.
“I continue to be pleasantly surprised at how quickly my patients are back to high level of activity following surgery,” said Dr. Kelly. “As knee replacement is becoming more common in younger patients, it is important that we try to replicate each patient’s unique anatomy to deliver the best functional outcome. Kinematic alignment knee replacement has been a game changer for patients in my practice.”
Functional outcomes for patients requiring a total knee procedure have improved with the development of the concept of Kinematic Alignment, which restores the native pre-arthritic alignment through anatomic resurfacing, minimizing ligament releases, and allows for a more natural knee movement. This approach has been shown to improve patient satisfaction compared to the more traditional techniques [1-3]. In recent years, clinical studies have highlighted how the Medacta GMK Sphere is a particularly suitable implant for Kinematic Alignment, with the potential to further enhance patient outcomes compared to other knee designs [4-6].
Built upon the legacy of the GMK Sphere knee’s ball-in-socket design, the GMK SpheriKA knee offers patients an implant that potentially feels more natural and stable during daily activities, by replicating the movement of the healthy knee. The GMK SpheriKA knee is the world’s first implant system specifically designed on the principles of Kinematic Alignment, which allows surgeons to achieve optimal patellar tracking in a wider range of patients [7-8].
MyKA, Medacta’s Kinematic Alignment Platform, provides surgeons with the most comprehensive solution to safely and reproducibly perform Kinematic Alignment. In addition to the GMK SpheriKA knee, it includes dedicated instrumentation and a tailored education program provided by the M.O.R.E. Institute, Medacta’s dedicated education program, supported by an international network of expert surgeons. Moreover, the platform is enhanced by cutting-edge technologies, such as a dedicated planning protocol for the MyKnee 3D printed patient-matched guides and NextAR Knee Augmented Reality surgical application, which provides unique real-time data to efficiently complement the operative 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.
