A Study to Evaluate the Conformis iTotal Identity Knee Replacement System

The iTotal® Identity KRS is a tri-compartmental semi-constrained knee prosthesis composed of three components: a Femoral Component, a Tibial Component, and a Patellar Component.Using patient imaging, a patient-specific implant is designed that best meets the geometric and anatomic requirements of the specific patient. The treatment allows for the placement of a cemented metallic device designed from the patient's natural bone geometry. This process allows definition of the shape and size of the femoral and tibial components of the implant, as well as the disposable instrumentation.
