iMNS MEDACTA NAVIGATION SYSTEM: WE MADE IT SIMPLE The development in knee joint replacement, producing improved clinical outcomes expectation, demands increasing accuracy in implant positioning. Computer Assisted Surgery dramatically improves precision in restoring the correct alignment of lower limb. The postoperative mechanical axis was within 3° of neutral mechanical alignment in 95% of the navigated cases vs 84% of the conventional cases  and the undesired outliers decreased. Accuracy was improved with navigation. To answer to this need Medacta has developed the iMNS - Medacta Navigation System.
