Alignment and Balance Methods in Total Knee Arthroplasty.

Abstract

Total knee arthroplasty is one of the most commonly performed orthopaedic surgical procedures in the United States. Primary concepts in the surgical technique include restoring limb alignment and soft-tissue balance about the knee. Currently, traditional mechanical alignment concepts that focus on restoring neutral limb alignment have been challenged by the principle of kinematic alignment. In addition to these recent philosophical challenges, new technologies have been introduced to help the surgeon more accurately achieve optimal limb alignment and soft-tissue balance.
