Overview
Brief Summary
Information provided to patients modifies their expectations with surgery. The effects of preoperative audiovisual information on expectations with total knee replacement (TKR) have not been investigated. The purposes of this study were to investigate the effectiveness of an educational videodisc on the modification of pre-operative patients' expectations with TKR 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.

Eligibility Criteria
Inclusion Criteria
- •Patients with knee osteoarthritis waiting for total knee replacement.
Exclusion Criteria
- •Cognitive disorders or language barriers precluding medical interview.
- •Contralateral total knee replacement.
- •History of revision total knee replacement.
- •History of unicompartmental knee arthroplasty
Outcomes
Primary Outcomes
Change from baseline in patient-reported postoperative expectatives about the results of total knee replacement to inmediately after receiving audiovisual plus verbal information (intervention grou) or only verbal information (control group)
Time Frame: Baseline and 1 month later (1 month before surgery)
The study measures the patient's expectatives about the improvement of pain, function, and psychological well-being after undergoing total knee replacement. These expectatives are measured through the Hospital for Special Surgery Knee Replacement Expectations Survey (KRES), and a score ranging from 0 to 100 is reported.
