Description

Based on the knee anatomy and kinematic studies performed by Prof. Michael Freeman and Prof. Vera Pinskerova[6], the GMK Sphere is an innovative total knee implant designed to deliver maximum functional stability with the goal of increasing TKA patient satisfaction during activities of daily living and decreasing post-operative knee pain. GMK Sphere is also available with SensiTiN, a ceramic-like coating designed to reduce the release of metal ions from the implant. Technical Data: STABILITY GMK Sphere features a fully congruent medial compartment providing: High stability throughout the range of motion No paradoxical motion between femur and tibia No implant-related “mid-flexion” instability NATURAL PATELLAR TRACKING GMK Sphere replicates natural lateralised patella tracking to reduce patello femoral joint pressure and address anterior knee pain: Trochlea groove lateralised by 2 mm to enable natural patella tracking. Flattened medial trochlear wall prevents patello-femoral overstuffing minimising retinacular tension. Anatomic patellar implant with medialised dome allows for optimal bony coverage with reduced soft tissue tension, improved stability and contact area. ANATOMICAL FIT Extensive anthropometric research on a unique global database containing more than 15,000 CT and MRI scans of knees validated the: Range of 13 femoral sizes with 2 mm increments that best fit a broad spectrum of anatomic profiles Anatomically shaped tibial baseplate Range of inserts with 1 mm increments The combination of 13 femoral sizes and inserts with 1 mm increments allows the surgeon to “fine tune” ligament balance and improve stability throughout the range of motion.
