Rotational Alignment of the Femoral Component in Computer-Assisted Total Knee Arthroplasty
This study compared two Computer Assisted Surgery (CAS) methods in 212 total knee arthroplasties to evaluate the differences between anatomic landmark axes in determining rotational position of the femoral component. Overall, there were large variations between CAS defined component orientation using an optimized gap-balancing technique and component orientation using anatomic reference axes (r...
متن کاملThe variability of femoral rotational alignment in total knee arthroplasty.
BACKGROUND Several reference axes are used to establish femoral rotational alignment during total knee arthroplasty, but debate continues with regard to which axis is most accurately and easily identified during surgery. Computer-assisted navigation systems have been developed in an attempt to more accurately and consistently align implants during total knee arthroplasty, but it is unknown if n...
متن کاملThe Effect of Sagittal Femoral Bowing on the Femoral Component Position in Total Knee Arthroplasty
Background: In the current study, we investigated that how sagittal femoral bowing can affect the sagittal alignment ofthe femoral component in total knee arthroplasty (TKA).Methods: There were 25 patients underwent TKA. Long leg radiography in lateral view was performed. The sagittalfemoral bowing (SFB) and component alignment in relation to the sagittal mechanical axis and distal anterior cor...
متن کاملA clinical study of the rotational alignment of the femoral component in total knee arthroplasty
We describe here various surgical options to obtain a correct rotational alignment of femoral component in total knee arthroplasty (TKA). The correct rotational alignment is the key point to obtain a rectangular balanced flexion gap as well to have a good patellar tracking. For that reason, rotation alignment largely affects postoperative kinematic results particularly during flexion.
متن کاملAveraging different alignment axes improves femoral rotational alignment in computer-navigated total knee arthroplasty.
BACKGROUND Computer navigation systems generally establish the rotational alignment axis of the femoral component on the basis of user-defined anatomic landmarks. However, navigation systems can also record knee kinematics and average alignment axes established with multiple techniques. We hypothesized that establishing femoral rotational alignment with the use of kinematic techniques is more a...
