Early Outcomes of Kinematic Alignment in Primary Total Knee Arthroplasty: A Meta-Analysis of the Literature

Small deviations from the traditional mechanical axis alignment in TKA do not appear to impact overall survivorship or complication rates at short-term follow-up. Functional outcome as measured by the Knee Society Score favored kinematic alignment. These preliminary results illustrate the concept that there may be more than a single alignment target for all patients undergoing primary TKA.
