A comprehensive platform
for personalized TKA
Kinematic Alignment Total Knee Arthroplasty aims to personalize joint line reconstruction through anatomic resurfacing, with little to no ligament releases.
Studies show the potential of KA to improve knee function and patient satisfaction[1,2].
Medacta offers the most comprehensive platform for Kinematic Alignment.
The Kinematic Alignment Platform (MyKA) includes a particularly suitable implant for kinematic alignment supported by dedicated instruments and technologies and a tailored M.O.R.E. Education Program.
To potentially further improve KA results and ultimately patient satisfaction, Medacta has developed GMK SpheriKA, the first KA-optimized implant. GMK SpheriKA was developed starting from the strong heritage of GMK Sphere, with a particular focus on the anterior aspect of the femur.
A dedicated Kinematic Alignment instrumentation was developed to perform a personalized, reproducible surgical technique based on measured bone resections[5].
A web-based 3D pre-operative planning is available to kinematically align the implant using the proven accuracy of our MyKnee 3D printed patient-specific solution[6,7].
A tailored education program and scientific events created with an
ever-growing network of KOL.
