The ART of Knee Replacement

Optimizing patient outcomes through state-of-the-art, personalized solutions

MyKA

PERSONALIZED TECHNIQUE

Kinematic Alignment (KA)

Kinematic Alignment (KA) is technique that resurfaces the knee to its pre-arthritic state, restoring the native joint line orientation and the pre-arthritic alignment. KA eliminates the need for ligament release, leading to quicker recovery1,2, improved functionality3,4,5, and patient satisfaction1,6,7.

SpheriKA

OPTIMIZED IMPLANT

GMK SpheriKA

The first and only KA-optimized implant, providing unparalleled stability8,9,10,11 through the medial Ball-in-Socket design, potentially reducing post-operative swelling12 and accelerating recovery. The KA-optimized anterior aspect accommodates patient-specific patella tracking and potentially further improves patient satisfaction when combined with KA.

Subvastus

MUSCLE AND TISSUE SPARING APPROACH

Subvastus

A muscle-sparing approach that preserves the quadriceps13,14,15, facilitating faster functional recovery16 and pain reduction16 without compromising visibility and access to the joint.

MySolutions

PERSONALIZED TECHNOLOGIES

MySolutions Personalized Ecosystem

MySolutions Personalized Ecosystem is Medacta’s end-to-end ecosystem of advanced digital solutions, connecting the entire patient care pathway. Within the MySolutions Personalized Ecosystem, MyKnee enables precise 3D planning and patient-matched 3D printed guides execution, while NextAR supports intraoperative augmented reality guidance and real-time soft-tissue insights.

The M.O.R.E. Institute, Medacta's top-notch education platform, is where ART becomes actionable. It makes muscle- and tissue-sparing approaches and techniques learnable, implant innovation and dedicated instruments adoptable, and personalized technologies reproducible across a broad range of surgical settings and experience levels. Training programs are comprehensive and surgeon-focused, covering every step of the journey: from first exposure to a new approach, through OR support and proctoring, to continuous skill refinement over time.
