Comparison of the Tibiofemoral Rotational Alignment After Mobile and Fixed Bearing Total Knee Arthroplasty

The anatomic landmark for the anteroposterior (AP) axis of the proximal tibia and its variability was investigated in this study in order to determine whether a certain landmark could be employed as a reference axis for the proximal tibia after rotating platform mobile bearing (RP-MB) and fixed bearing (FB) total knee arthroplasties (TKAs).
