Femoral component rotation from a total knee prosthesis can be determined by either measured resection technique or balanced gap technique. With the implantation technique, femoral vary freely within restrictions produced soft tissue structures. Because internal might cause patella problems, effect of ligament releases on in prospective clinical study was studied. intraoperatively with tensor applied flexion at 150 N 87 knees. Great interpatient variability found; rotation, reference posterior condyles, ranged −4° to 13°. There no difference knees without extension. However, major medial release had less external than minor lateral releases. Preoperative alignment influence rotation. The use theoretically will result gap, but amount variable owing patient and variation Level Evidence: II, therapeutic study. See Guidelines for Authors complete description levels evidence.
