Pre-operative predictors of post-operative falls in people undergoing total hip and knee replacement surgery: a prospective study.

Introduction: Pain and disability often persist following hip (THR) and knee replacement (TKR) surgery predisposing patients to increased risk of falling. This study identified pre-operative predictors for post-operative falls in TKR and THR patients, and the incidence and circumstances of falls in the 12 months post-surgery.

Materials And Methods: A survey was undertaken of patients before THR and TKR, and was repeated 12 months post-operation.

Development and validation of a questionnaire assessing discrepancy between patients' pre-surgery expectations and abilities and post-surgical outcomes following knee replacement surgery.

Purpose: The discrepancy between patient-desired outcomes and achievable functional outcomes is a source of patient dissatisfaction. This paper reports development and validation of a questionnaire to assess this discrepancy in patients undergoing knee replacement surgery.

Methods: The initial questionnaire (Knee Surgery Perception Questionnaire, KSPQ) comprised two parts.
