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.
Based on knee anatomy and kinematic studies, GMK Sphere is a medially stabilized implant that has been proven to reproduce natural motion of the knee. GMK Sphere and Kinematic Alignment share the same ultimate goal of restoring the biomechanics of the natural knee.
A dedicated Kinematic Alignment instrumentation was developed to perform a personalized, reproducible surgical technique based on measured bone resections.
