Effects of an educational audiovisual videodisc on patients' pre-operative expectations with total knee arthroplasty: a prospective randomized comparative study.
Trial report in Knee surgery, sports traumatology, arthroscopy : official journal of the ESSKA, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 2 of them syntheses that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTo 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.
methodsNinety-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.
resultsExpectations 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.
conclusionsBased 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.
