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 .
A randomised controlled clinical trial and gait analysis of fixed- and mobile-bearing total knee replacements with a five-year follow-up.
This study compared the outcome of  total knee replacement ( TKR ) in adult patients with fixed- and mobile-bearing prostheses during the first post-operative year and at five years ' follow-up , using gait parameters as a new objective measure . This double-blind r and omised controlled clinical trial included 55 patients with mobile-bearing ( n = 26 ) and fixed-bearing ( n = 29 ) prostheses of the same design , evaluated pre-operatively and post-operatively at six weeks , three months , six months , one year and five years . Each participant undertook two walking trials of 30 m and completed the EuroQol question naire , Western Ontario and McMaster Universities osteoarthritis index , Knee Society score , and visual analogue scales for pain and stiffness . Gait analysis was performed using five miniature angular rate sensors mounted on the trunk ( sacrum ) , each thigh and calf . The study population was divided into two groups according to age ( ≤ 70 years versus > 70 years ) .  Improvements in most gait parameters at five years ' follow-up were greater for fixed-bearing TKRs in older patients ( > 70 years ) , and greater for mobile-bearing TKRs in younger patients ( ≤ 70 years ) . These findings should be confirmed by an extended age controlled study , as the ideal choice of prosthesis might depend on the age of the patient at the time of surgery
