Purpose: the aim of the present study was to measure patient perception in the early period after knee replacement surgery and to correlate health status with the surgery-related outcome. Methods: thirty-eight consecutive patients who underwent total knee replacement were evaluated before surgery; at the time Radiographic evaluation was used to assess limb alignment and the Oxford Knee Score (OKS) to assess objective outcome. Health outcome was measured with the three-level version of the EuroQol – five dimension (EQ-5D-3L) selfadministered questionnaire, a standardized instrument used to measure patient’s perception of health status. Evaluation was performed before surgery, at discharge from hospital, and six weeks after surgery. Results: the mean overall EQ-5D-3L scores were 10.23 before surgery, 8.34 at discharge from the hospital, and 6.52 at six weeks. The overall EQ-5D-3L score before surgery was greater than 8 points in 31 of the 38 patients, ranging from 5 to 8 points in 21 of the 38 patients at the discharge and greater than 8 points in six of the 38 patients six weeks after surgery. Patients with scores of over 8 points at six weeks also scored more than 10 points on the discharge assessment. Conclusions: analysis of early patient reports of performance after TKR showed marked changes in the level of satisfaction during the first six weeks after surgery. An EQ-5D-3L score of 8 or more at follow-up should be considered a sign that the patient has not achieved satisfaction and, accordingly, should be studied in the context of a personalized follow-up schedule in order to identify as soon as possible the causes of impairment. Level of Evidence: Level IV, prognostic case series.
