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 .
Fixed- vs mobile-bearing total knee arthroplasty: does it make a difference?--a prospective randomized study.
The purpose of this prospect i ve , r and omized study was to compare the early clinical and functional results of primary total knee arthroplasty using a fixed-bearing ( FB ) and a rotating-platform ( RP ) prosthesis .  Outcomes including range of motion ( ROM ) , Knee Society Score , Western Ontario MacMaster ( WOMAC ) , and Short Form-36 ( SF-36 ) were measured preoperatively and at 6 weeks , 3 months , 6 months , 1 year , and 2 years . Radiographic analysis was performed . There were 72 FB and 68 RP knees . The RP group had a greater ROM at 6 weeks and 1 year . This difference was not statistically significant at 2 years . There were no differences in the ROM at any other period . There were no significant differences in Knee Society Score , Short Form-36 , or Western Ontario MacMaster scores at any period . No clinical ly significant differences were noted in the radiographic analysis . The use of a FB or RP design did not affect the early functional outcomes after total knee arthroplasty
