BACKGROUND Mechanically aligned total knee arthroplasty can create a tight collateral ligament in 0° of extension, instability in a compartment between 0° of extension and 90° of flexion that is uncorrectable by collateral ligament release, and changes in limb and knee alignment from normal. The goal of the present study was to calculate the frequency and range of these undesirable consequences. METHODS Four methods of mechanically aligned total knee arthroplasty were simulated on fifty… CONTINUE READING
