ABSTRACT
PURPOSE:
The purpose of this study was to investigate the correlation between rotational axes of femur and tibia with the use of Linker. MATERIALS ANDMETHODS:
This study was carried out from August 2009 to February 2010 on 54 patients (106 knees), who were diagnosed with simultaneous bilateral total knee arthroplasty. With the use of postoperative computed tomography scans, it was investigated how much the rotational angle of femoral and tibial components matched.RESULTS:
The tibial component was internally rotated for the femoral component at an angle of 0.8degrees. The femoral component was externally rotated for the surgical transepicondylar axis (TEA) at an angle of 1.6 (range from 4.8degrees of internal rotation to 7.9degrees of external rotation, SD=2.2degrees), and the tibial component was externally rotated for the surgical TEA at an average angle of 0.9 (range from 5.1degrees of internal rotation to 8.3degrees of external rotation, SD=3.1degrees).CONCLUSION:
The femoro-tibial synchronizer helped to improve the orientation and positioning of both femoral component and tibial component, and also increase the correlation of the rotational axes of the two components.
