Key Features
The brochure highlights the GMK Sphere knee implant, emphasizing its stability and patient satisfaction. A study showed 76% of patients preferred the medially stabilized device due to its natural feel, strength, and stability.

Patient Satisfaction After Knee Arthroplasty
Despite the longevity of total knee arthroplasty (TKA), many patients experience functional deficits. Approximately 20% of TKA patients are dissatisfied, often due to anterior/posterior instability during common activities.

Patient-Specific Kinematics
The GMK Sphere accommodates individual kinematic motion patterns, offering "ball in socket" stability in the medial compartment and freedom in the lateral compartment.

Natural Patellar Tracking
The implant replicates natural patellar tracking, reducing joint pressure and anterior knee pain through a lateralized trochlea groove and an anatomically shaped patellar implant.

Stability
The GMK Sphere provides high stability throughout motion, eliminating paradoxical motion and mid-flexion instability.

Anatomical Fit
Extensive research led to a range of femoral sizes and inserts, allowing surgeons to fine-tune ligament balance and improve stability.

Responsible Innovation
Medacta emphasizes evidence-based innovation, with the GMK Sphere undergoing extensive testing before launch.

Synergy
Features include a ceramic-like coating to reduce metal ion release, Vitamin E crosslinked UHMWPE for wear resistance, and a porous titanium coating for stability.
