The iTotal Patella is part of a patient-specific knee replacement system used for total knee arthroplasty. The system is intended for patients whose knee pain and disability cannot be addressed by replacing only one or two knee compartments.
The patellar component is made from ultrahigh-molecular-weight polyethylene or highly cross-linked vitamin E infused polyethylene. Patient-specific instruments help position the knee components and guide bone cuts during implantation.
System Use
The iTotal systems are indicated for knee conditions including osteoarthritis, traumatic arthritis, rheumatoid arthritis, osteonecrosis, deformity, and certain revision procedures. The system specifies cemented use.
