Increased femoral curvature and trochlea flexion in high-grade patellofemoral dysplastic knees
PurposeHigh-grade patellofemoral dysplasia is often associated with concomitant axial and frontal leg malalignment. However, curvature of the femur...

Maximum flexion and lateral rollback revealed better patient satisfaction after total knee arthroplasty
IntroductionPatient satisfaction is an important outcome of total knee arthroplasty (TKA). However, we cannot predict how and why patients are...

Investigation of femoral condyle height changes during flexion of the knee: implication to gap balance in TKA surgery
BackgroundGap balance of the knee at 0° and 90° of flexion has been pursued in total knee arthroplasty (TKA) with the trans-epicondyle axis (TEA) as...
