Purpose Performing kinematically aligned total knee arthroplasty (TKA) with generic
instruments is less costly than patient-specific instrumentation; however, the alignment and …

Purpose The aim of this prospective study was to compare early clinical outcome,
radiological limb alignment, and three-dimensional (3D)-component positioning between …

Purpose A systematic review was conducted to answer the following questions:(1) Does
kinematically aligned (KA) total knee arthroplasty (TKA) achieve clinical outcomes …

The purpose of this study was to compare 2 alignment methods for total knee arthroplasty
(TKA): kinematic alignment with the use of patient-specific guides and mechanical alignment …

Background The optimal alignment technique for total knee arthroplasty (TKA) remains
controversial. We previously reported 6-month and 2-year results of a randomized controlled …

Purpose Kinematic alignment in TKA is supposed to restore function by aligning the
components to the premorbid flexion–extension axis instead of altering the joint line and …

Background Neutral mechanical alignment (MA) in total knee arthroplasty (TKA) aims to
position femoral and tibial components perpendicular to the mechanical axis of the limb. In …

Background Randomized controlled trials of kinematic alignment (KA) and mechanical
alignment (MA) in primary total knee arthroplasty (TKA) have to date demonstrated at least …

Purpose The joint line of the native knee is horizontal to the floor and perpendicular to the
vertical weight-bearing axis of the patient in a bipedal stance. The purposes of this study …

Successful total knee arthroplasty (TKA) has often been based on the restoration of the knee
to neutral alignment postoperatively. Numerous reports have linked malaligned TKA …
