TKR positioning

CONCEPT
WHAT IS KINEMATIC ALIGNMENT?

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].

 

WHAT DOES MEDACTA OFFER?

Medacta offers the most comprehensive platform for Kinematic Alignment. 
The Medacta Individualized Kinematic Alignment (MIKA) platform includes a particularly suitable implant for kinematic alignment supported by dedicated technologies and a dedicated M.O.R.E. Education Program.

SPECIAL FEATURES
A COMPREHENSIVE APPROACH FOR PERSONALIZED TKR POSITIONING

GMK SPHERE

Based on knee anatomy and kinematic studies[3], GMK Sphere is a medially stabilized implant that has been proven to reproduce natural motion of the knee[4]. GMK Sphere and Kinematic Alignment share the same ultimate goal of restoring the biomechanics of the natural knee.

CALIPERED TECHNIQUE

A dedicated Kinematic Alignment instrumentation was developed to perform a personalized, reproducible surgical technique based on measured bone resections[5].

MYKNEE MIKA

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].
