Partial Knee Application is an upgrade to RIO-PKA (K112507). The features of this application are to improve overall performance of the system in supporting partial knee arthroplasty. Partial Knee Application is used with RIO which includes an optical detector, robotic arm, and guidance module. In addition, the application is designed to be used with a pre-operative planning laptop, as well as both reusable and disposable instrumentation. The main RIO platform includes an optical detector, computer, dedicated instrumentation, operating software, tools and accessories, cutting system, and a robotic arm.
