How accurate is anatomic limb alignment in predicting mechanical limb alignment after total knee arthroplasty?
BACKGROUND Anatomic limb alignment often differs from mechanical limb alignment after total knee arthroplasty (TKA). We sought to assess the accuracy, specificity, and sensitivity for each of three commonly used ranges for anatomic limb alignment (3-9°, 5-10° and 2-10°) in predicting an acceptable range (neutral ± 3°) for mechanical limb alignment after TKA. We also assessed whether the accurac...
متن کاملA comparative assessment of alternatives to the full-leg radiograph for determining knee joint alignment
UNLABELLED BACKGROUND The purpose of this study was to assess the concurrent validity of alternative measures of frontal plane knee alignment, namely the radiographic anatomic axis and two clinical measures in patients complaining of knee malalignment as compared with the mechanical axis on full-length radiograph of lower limbs. METHODS The knee-alignment angle was measured in 100 knees of...
متن کاملAssessment of lower limb alignment: supine fluoroscopy compared with a standing full-length radiograph.
BACKGROUND While a full-length standing anteroposterior radiograph of the lower extremity provides the best radiographic method for assessing limb alignment, other methods must be used intraoperatively. We have employed intraoperative fluoroscopy with use of an electrocautery cord to assess limb alignment in the supine patient. METHODS We retrospectively compared the measurements of lower lim...

متن کاملEffective measurement of knee alignment using AP knee radiographs.
The gold standard for measuring knee alignment is mechanical axis determined using full-limb radiographs (FLR). Measurement of joint alignment using antero-posterior (AP) knee radiographs is more accessible, economical and involves less radiation exposure to the patient compared with using full-limb radiographs. The aim of this study was to compare and assess the reproducibility of knee joint a...
