DEVICE: iTotal® PS (M572TPS1111111021)

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.

A sterile implantable artificial substitute for a knee joint typically designed to replace all the articulating surfaces of the damaged/degenerative joint [total knee arthroplasty (TKA)] or for prosthesis revision; it is implanted when the posterior cruciate ligament is sacrificed and uses a “cam and post” mechanism to replace the stabilizing function of the ligament. It includes femoral, tibial, and patellar components that articulate and with parts made of metal, ceramic, and/or polyethylene (PE); it may be implanted with or without bone cement and is often used in cases where bone stock and mediolateral stability are good in the face of severe deformities or ligament degeneration.
