Background Rotational alignment of prosthetic components in total knee arthroplasty (TKA)
is important to successful outcomes. Component malrotation is a known cause of revision …

Background Proper rotational alignment of the femoral component is critical for a successful
total knee arthroplasty (TKA). Controversy remains regarding the optimal intraoperative …

Surgeon-dependent factors such as optimal implant alignment of the tibial component are
thought to play a significant role in the outcome following primary total knee arthroplasty …

Background Correct rotational alignment of the femoral and tibial component is an important
factor for successful TKA. The transepicondylar axis is widely accepted as a reference for the …

Purpose: This study aimed 1) to identify the rotational axis of the femur that provides a
balanced 90 flexion space in TKA, 2) to assess the changes in the flexion space in deep …

Background Tibiofemoral components rotational congruency affects the total knee
arthroplasty (TKA) success. The smart insert sensor (IS) helps to establish tibial component …

Purpose: to compare the anterior tibial surface curvature, the Akagi's line and the medial
third of the tibial tubercle in order to assess which is the most reliable landmark for correct …

Background Clinical consequences of alignment errors in total knee replacement (TKR)
have led to the rigorous evaluation of surgical alignment techniques. Rotational alignment in …

Internal and external (IE) malrotation of the femoral and tibial components is associated with
poor function after total knee arthroplasty (TKA). 1, 2 In mechanically aligned TKA, there are …

Background Rotational mismatch between femoral and tibial components has been
recognized as a risk factor of unsuccessful total knee arthroplasty (TKA), but a main cause of …
