Early assessment of patient perception of outcome in total knee replacement.

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) self-administered questionnaire, a standardized instrument used to measure patient's perception of health status.
