DEVICE: iTotal® Cruciate Retaining (CR) Knee Replacement System (M572TCR1211111011)

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 (e.g., arthritic) joint [total knee arthroplasty (TKA)]; it is designed to be implanted with retention of the posterior cruciate ligament. It typically includes femoral, tibial, and patellar components that articulate and with parts made of metal, ceramic, and/or polyethylene (PE). The device may be implanted with or without bone cement and is typically used in cases where bone stock is good and supporting ligaments provide adequate stability.
