1 · What the graph read from 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.

Abstract

backgroundPatient satisfaction has increasingly been recognized as an important measure after total knee arthroplasty (TKA). However, we do not know yet how and why the patients are satisfied or dissatisfied with TKA. QUESTIONS/PURPOSES: We asked: (1) After TKA, how satisfied are patients and which activities were they able to do? (2) Are patient-derived scores related to physician-derived scores? (3) Which factors affect patient satisfaction and function?

methodsWe retrospectively evaluated 375 patients who had undergone 500 TKAs between February 22, 2000 and December 1, 2009. We sent a questionnaire for The 2011 Knee Society Knee Scoring System to the patients. We determined the correlation of patient- and physician-derived scores and factors relating to the five questions relating to satisfaction and the 19 questions relating function. The minimum followup was 2 years (mean, 5 years; range, 2-11 years).

resultsThe mean score for symptoms was 19 (74%), 23 (59%) for patient satisfaction, 10 (64%) for patient expectations, and 53 (53%) for functional activities. We found a poor correlation between the patient-derived and the physician-derived scores. Old age and varus postoperative alignment negatively correlated with the satisfaction. Varus alignment and limited range of motion (ROM) negatively correlated with the expectation. Old age, rheumatoid arthritis, and limited ROM negatively correlated with the functional activities.

conclusionsMost patients did not report symptoms, but they experienced difficulty with activities of daily living after TKA. Patient satisfaction is difficult to measure, but avoiding varus alignment and achieving better ROM appear to be important for increasing satisfaction and meeting expectations.
