Factors associated with pressure ulcer onset after knee replacement.

Objective: The aim of this study was to find the rate of pressure ulcers (PUs) in patients with knee replacements and identify predictive factors. The ability of the Braden scale to predict the onset of PUs was also investigated.

Method: A retrospective prognostic cohort study was carried out involving all consecutive patients undergoing knee replacement surgery.

At discharge gait speed and independence of patients provides a challenges for rehabilitation after total joint arthroplasty: an observational study.

Background: The level of functioning in people discharged from hospital after hip arthroplasty is very heterogeneous and prognostic factors are not fully understood. The aim of this study was to determine the mean level of autonomy achieved by such patients at discharge from hospital using the Iowa Level of Assistence (ILOA) scale as a measurement tool and to investigate the possible predictive factors of this autonomy.

Methods: It was conducted a prospective cohort study including hip arthroplasty patients treated consecutively in 2012.

Rasch analysis of the Iowa Level of Assistance Scale in patients with total hip and knee arthroplasty.

The aim of this study was to carry out a psychometric analysis, using both Classical Test Theory and Rasch analysis (RA) methods, of the Iowa Level of Assistance Scale (ILAS) administered in patients with recent total hip arthroplasty (THA) or total knee arthroplasty, to examine its metric properties and provide insights for a refined version. A total of 203 patients who had undergone THA or total knee arthroplasty were assessed using the ILAS for assistance needed during functional activities (ILAS-funct) and need for assistive devices (ILAS-dev) before discharge from the orthopedic ward. The responses were psychometrically analyzed using the Classical Test Theory and RA.
