Overall , there was a notable enhancement of joint function after the procedure , with a satisfactory mid- and long-term survival of the ceramic components , which is comparable to that of the conventional alloy components reported previously .
However , revision due to aseptic loosening , wear , and component fracture appeared to be rare , demonstrating the safety of in vivo use of ceramic bearings in the TKA procedure .
Conclusions Ceramic TKA implants show similar post-operative clinical results and survival rate compared to their conventional metallic counterparts .
Our results confirmed the safety of in vivo use of ceramic bearings in TKA , with rare implant breakage and aseptic loosening .
Purpose Ceramic bearings have been widely used in total hip arthroplasty ( THA ) , which result ed in satisfactory clinical outcomes due to the excellent tribological characteristics of the implants .
However , ceramic components are not commonly used in total knee arthroplasty ( TKA ) because of brittleness .
This study aim ed to gather and analyze information regarding the clinical outcomes ( including survival without revision , causes of revision , functional outcome , and incidence of loosening ) and reach a definitive conclusion about the use of ceramic femoral components in total knee arthroplasty .
An Oxidized Zr Ceramic Surfaced Femoral Component for Total Knee Arthroplasty
A ceramic surfaced oxidized Zr femoral component  was used in total knee replacemdent . Prior mechanical testing had shown a decrease in adhesive and abrasive wear using this material as compared with CoCrMo suggesting its use in younger patients in whom long-term PE wear is a consideration . The alloy had no demonstrable Ni impurities and was applicable to patients with Ni or Co allergies . In a r and omized prospect i ve study comparing femoral components of the same design but fabricated either of cast CoCrMo or oxidized Zr , there was a more rapid return of flexion and regaining functional milestones in the oxidized Zr group . No adverse effects had been observed at the 2-year evaluation
