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.

Primary Outcome Measures:
  • 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) ] [ Designated as safety issue: Yes ]
    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.

Arms Assigned Interventions
Experimental: Audiovisual videodisc and medical verbal information Behavioral: Educational audiovisual videodisc and medical verbal information
General and specific medical verbal information and ten-minute DVD where the process from admission to the surgical intervention, recovery room, immediate postoperative care, and outpatient care at two, six, and twelve months after surgery was shown. The video included experiences of patients with respect to pain and function and examples of functionality during daily life activities such as stairs, kneeling or squatting. The video also demonstrated the facilities and rehabilitation techniques employed in the Physical Medicine and Rehabilitation Service.
Active Comparator: Medical verbal information Behavioral: Medical verbal information
General and specific verbal information provided by both the surgeon and a specialized nurse including basics of surgical technique, potential complications, and rehabilitation.
