Ligamentous balancing in rotating-platform knees.

Abstract

The primary objectives of total knee arthroplasty are to reduce pain, maximize range of motion (ROM), and provide stability through the gait cycle. Pain relief depends on proper ligamentous balancing and solid implantation. Solid implantation is typically assured through cementation, whereas soft-tissue balancing is vital to ensure maximum ROM and stability. Special consideration should be given to obtaining proper axial alignment, symmetric tension on the ligaments in both flexion and extension, and equalizing the flexion extension gaps. Strategies to ensure proper alignment and ligamentous balancing intraoperatively are discussed.
