Abstract: Background: The importance of correct sizing of components for TKA for an optimal function and long-term results has been stressed in many reports. Proper sizing of both femoral and tibial component in both knees is necessary to maximize outcomes and reduce the risk of complications.
Aims: To analyse the incidence of asymmetry of femoral and tibial components among bilateral knee Arthroplasty cases.
Methods: A retrospective review of operative notes and outpatient charts was performed on all patients undergoing simultaneous and two-staged bilateral TKA at this institution from 2014 to 2016.
Conclusion: Good range of movement of both knee joints provides the support that proper component selection whether symmetrical or asymmetrical is the keystone for successful bilateral total knee arthroplasty.
