Abstract/OtherAbstract:
PURPOSE: To investigate the effectiveness of an educational videodisc in modifying pre-operative patients' expectations with total knee arthroplasty (TKA) and to find a biophysical profile of subjects in whom this videodisc could be most effective. It was hypothesized that patients receiving standard information plus additional medical information through audiovisual videodiscs would modify their pre-operative expectations more than those only receiving the standard information through medical interviews. METHODS: Ninety-two patients (age, 50-90 years) with knee osteoarthritis waiting for TKA were randomized into two groups. All patients received general verbal information about this procedure. Forty-two patients (study group) additionally viewed an educational videodisc related to the whole process of TKA, whereas 50 patients did not view it (control group). Patients completed baseline and post-videodisc questionnaires regarding their expected results after TKA. RESULTS: Expectations with TKA were not modified by the audiovisual videodisc, except for knee range of motion and use of stairs. There were no differences in change of expectations between groups depending on demographic, functional, health, emotional, and cognitive variables, except for body mass index. The overall pre-operative, pre-intervention expectations were not modified by the audiovisual videodisc. CONCLUSIONS: Based on these results, the use of this complementary tool may not be systematically recommended. In addition, it was not possible to identify a biophysical profile of patients in whom the intervention could be most effective. LEVEL OF EVIDENCE: Therapeutic study-Prospective randomized non-blinded comparative study, Level II.
