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 .
Relationship between joint gap difference and range of motion in total knee arthroplasty: a prospective randomised study between different platforms
The objective of this study was to investigate the range of motion ( ROM ) of the knee before and four years after total knee arthroplasty ( TKA ) with a mobile or fixed type of platform and to prospect ively evaluate whether there was a difference in ligament balance between the platform types . The subjects were 68 patients involving 76 joints . The mobile type was used in 31 joints and fixed type in 45 joints by employing a prospect i ve r and omised method . The passive maximum ROM was measured using a goniometer before and four years after surgery . Also , the intraoperative knee ligament balance was measured . The postoperative extension ROM was significantly improved after TKA using a mobile bearing type compared with that employing a fixed bearing type . In TKA using the former , the intraoperative gap difference was not related to the postoperative flexion angle of the knee . However , they were related in TKA using a fixed bearing type , with a positive correlation regarding the flexion gap
Similarly , no difference was revealed between the groups for radiological outcomes or general health results .
