Positive Cueing in Knee Arthroplasty.

Two weeks before the surgery, in the outpatient clinic (during their preoperative appointment), the pre-surgery information video was shown to the patients. Patients were randomly allocated to either the positive cueing group (intervention) or the standard care group (control) with Castor EDC (14) using a variable block randomization model. Patients did not know whether they watched the adapted video or the standard video.
