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 versus rotating platform total knee arthroplasty: a prospective, randomized, single-blind study.
The purpose of this r and omized , single-blind clinical trial was to compare a rotating platform ( RP ) total knee arthroplasty to a fixed-bearing ( FB ) total knee arthroplasty . Ninety-five knees in 69 patients were implanted by 2 surgeons . There were no significant differences in the preoperative demographics . At a minimum of 2-year follow-up , clinical outcomes and complication rates were similar , with the exception that the RP group had significantly better stair-climbing scores ( P = .04 ) . Postoperative range of motion was equally good in both groups ( FB knees , 1 ° -125 ° ; RP knees , 1 - 126 ° ) . There were no bearing dislocations in the RP group . In conclusion , this RP design performs at least as well as the FB version , and the RP patients reported better stair-climbing ability . Enthusiasm for this finding should be tempered by the relatively small sample size
