DEVICE: iTotal® CR iPoly XE™ Insert Kit (M572RCR0201000011)

A collection of sterile hand-held surgical instruments intended to be used during total knee arthroplasty (TKA), either manually or as a computer-assisted surgery (CAS) device, to aid in the navigation/placement of the prosthesis or other instruments. Components may be used for the following applications: 1) to hold/align/fix bone preparation instruments, prosthesis, or prosthesis component; 2) to provide relative position landmarks; 3) to ascertain correct spatial orientation or limb alignment; and/or 4) as an interface between prosthesis components; the implant is not included. This is a single-use device.

An implantable device designed to articulate the femoral and tibial components of a knee joint prosthesis during primary or revision bicondylar knee joint replacement. It is typically a one-piece contoured polyethylene (PE) insert, or a more complex device (e.g., a guide arm with a stem that is inserted into the tibial tray and a polymer glide) which will better reproduce the flexion of the knee joint due to its capacity for lateral rotation and anterior/posterior movement. This device is typically made of metal and/or a polymer.
