Knee flexion angle (KFA) is one of the most critical factors for evaluating patients functional outcomes after total knee arthroplasty (TKA). Pre-operative knee flexion angle and intraoperative drop leg test are accepted as predictors of post-operative KFA after TKA. A pre-operative test performed after anaesthetic procedures helps overcome the limitation caused by pain. However, the most appropriate evaluation time to best predict the KFA after TKA has not been demonstrated. Pre-anesthetic kne
