Ritter,[4] in his study of 3066 patients (4727 knees) who had undergone primary TKA, looked at factors that predict postoperative range of motion. The principal predictive factor of the postoperative range of motion was the preoperative range of motion. Removal of posterior osteophytes and release of the deep medial collateral ligament, the semimembranosus tendon, and the pes anserinus tendon in patients with large preoperative varus alignment, and the attainment of a good intraoperative range of motion, improved the likelihood that a good postoperative range of motion would be achieved.[4,5]
