A simple method for accurate rotational positioning of the femoral component in total knee arthroplasty
Background and purpose - There are many techniques for placing the femoral component in correct rotational alignment in total knee arthroplasty (TKA), but only a few have been tested against the supposed gold standard, rotation determined by postoperative computed tomography (CT). We evaluated the accuracy and variability of a new method, the clinical rotational axis (CRA) method, and assessed ...
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 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 کاملAnthropometric Measurements of Distal Femur to Design the Femoral Component of Total Knee Arthroplasty for the Iranian Population
Background: Acquiring knowledge about anatomic and geometric quantities of bones is among the most vitalparameters in orthopedic surgery that has a significant effect on the treatment of various disorders and subsequentoutcomes. The aim of this study was to obtain anthropometric information for distal femur in order to compare withsimilar dimensions of prosthesis used in total...
