The legion knee revision system was designed as a follow and improvement to the Genesis II knee system- allowing for a surgeon directed femoral rotation as opposed to the in-built femoral rotation in the previous system. This is a prospective review of consecutive patients who underwent knee revision surgery using the legion knee system. Clinical and functional assessments were carried out preoperatively, one year and 2 years post op. Radiographic evaluation was done at 1 and 2years follow up. Standard knee scoring systems (American Knee Scores-AKS, and Oxford score were used for the clinical and functional evaluation of these patients. The WOMAC score was also used to assess for pain, stiffness and social function in these patients. The radiographic assessment included review of standing AP, lateral and skyline views. Figgie's method was used to measure the joint line reproduction. A difference of 5 mm (pre = op/post-op) was deemed satisfactory.Introduction
