The pre-anesthetic period is the best time to evaluate the knee flexion angle for predicting the flexion angle after total knee arthroplasty: A prospective cohort study

Completed

• Conditions: 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 knee flexion angle; knee flexion angle; total knee arthroplasty; plateau; predicting; phase
