Similarly , no difference was revealed between the groups for radiological outcomes or general health results .
Controversy exists regarding the clinical and radiological differences in outcomes between  fixed-bearing ( FB ) and mobile-bearing ( MB ) total knee arthroplasties ( TKAs ) at the mid- or long-term follow-up .
We therefore conducted a meta- analysis and systematic review of r and omized controlled trials ( RCTs ) that have evaluated FB and MB TKAs .
No difference in ROM and knee function between mobile and floating platforms in TKA
Purpose The purpose of this study was to determine whether the floating platforms ( FP ) were superior to rotating platforms ( RP ) in computer-navigated total knee  arthroplasty ( TKA ) comparing the range of motion ( ROM ) as well as clinical and subjective function of the knee . Methods This retrospective non-r and omized single-centre cohort study includes 255 patients with a primary implanted computer-navigated e.motion ™ ( Aesculap B. Braun ) TKA system , implanted because of clinical and radiological verified gonarthrosis . In 129 patients , the FP platform was implanted  , and in 126 patients , the RP platform . As statistical procedures for differences between inlay type RP/FP in ROM and Knee Society Score ( KSS ) after 3- and 24-month follow-up , an analysis of covariance ( with risk factors gender , age , BMI , preoperative ROM and preoperative KSS ) was performed . Results Although preoperative ROM and knee society function score ( KSS partII ) were significantly higher in the FP group before surgery , there was no significant difference between RP and FP  in ROM and KSS at 3- and 24-month follow-up . Conclusion The FP platform design did not have an advantage in ROM as well as in clinical and subjective knee function compared with the RP platform in computer-navigated TKA neither in early follow-up examinations at 3 months postoperatively nor at long-time follow-up at 24 months postoperatively . Level of evidence Therapeutic study , Level III
