Linked Anatomic Kinematic Arthroplasty: A Unique Approach to Balancing in Total Knee Arthroplasty

Traditional approaches to total knee arthroplasty (TKA) aim to reestablish a neutral mechanical axis of the lower extremity. However, many studies have shown great variation in normal knee anatomy, suggesting that the ideal alignment may not be identical for every patient. Linked Anatomic Kinematic Arthroplasty (LAKA) offers a novel kinematic approach to TKA. Using computer navigation, LAKA technique can optimize the kinematic alignment while ensuring that coronal alignment is kept within standard mechanical ranges. This article will outline the surgical approach to LAKA and briefly review the outcomes of this approach.
