Composite Ceramics in Total Knee Arthroplasty: Two-Year Experience in Clinical Application

Total knee arthroplasty (TKA) has been developed into a safe and reliable procedure in orthopedic surgery. Nevertheless, in some cases, wear particles trigger the well-known cascade of osteolysis-inducing aseptic implant loosening. Furthermore, hypersensitivity to allergens such as chromium, cobalt, and nickel can lead to implant failure. These facts have led to a rising interest in research for solutions of alternative implant materials in TKA. The use of ceramics in total hip arthroplasty is based on excellent wear resistance and corrosion durability. These advantages have led to the development of a TKA system with a Biolox delta composite ceramic femoral component. In the present article, the clinical experience and radiological results of a 2-year follow-up in some standard and specific indications are presented. Furthermore, special features on intraoperative handling, advantages, as well as limitations in clinical application are demonstrated.
