According to the Orthopaedic Data Evaluation Panel (
ODEP) rating criteria,
GMK Sphere has been evaluated in a minimum cohort of 150 knees, demonstrating Kaplan-Meier survivorship data in line with cumulative percent of revision lower than 5% at ten years. The
ODEP rating is not awarded based only on a specific study (with selected surgeons), rather it comes from nationwide data of English and Welsh hospitals.
This excellent rating is confirmed and outmatched by the 3 years preliminary clinical outcomes of the
GMK Sphere ODEP study (performed in four centers in the UK and Belgium).
At three years follow-up, the implant demonstrates excellent survival with a survival rate of 99.72%. Both objective and subjective outcomes show consistent optimal values and witness the efficacy of the
GMK Sphere to achieve excellent clinical results and patient satisfaction.
