Predicting short stay total hip arthroplasty by use of the timed up and go-test.

Background: One of the most important steps before implementing short stay total hip arthroplasty (THA) is establishing patient criteria. Most existing criteria are mainly based on medical condition, but as physical functioning is associated with outcome after THA, we aim to evaluate the added value of a measure of physical functioning to predict short-stay THA.

Methods: We used retrospective data of 1559 patients who underwent an anterior THA procedure.

Association Between Preoperative Vitamin D Status and Short-Term Physical Performance after Total Hip Arthroplasty: A Prospective Study.

Background: Insufficient serum vitamin D concentrations (50-75 nmol/L) are prevalent in 40-65% of patients who require total hip arthroplasty (THA). This could impair physical recovery after surgery. This study investigated the association between preoperative vitamin D status and physical performance after THA.

Personal meaning in relation to daily functioning of a patient in physical therapy practice: narratives of a patient, a family member, and physical therapist.

Purpose: To get insight into personal meaning of a person involved in a physical therapy intervention.

Methods: Mrs. A, a 76-year-old woman is referred to a physical therapist (PT) for assessment of functioning and training before total hip arthroplasty (THA).

The Influence of Muscle Weakness on the Association Between Obesity and Inpatient Recovery From Total Hip Arthroplasty.

Background: There is ongoing discussion about whether preoperative obesity is negatively associated with inpatient outcomes of total hip arthroplasty (THA). The aim was to investigate the interaction between obesity and muscle strength and the association with postoperative inpatient recovery after THA.

Methods: Preoperative obesity (body mass index [BMI] >30 kg/m) and muscle weakness (hand grip strength <20 kg for woman and <30 kg for men) were measured about 6 weeks before THA.

Preoperative prediction of inpatient recovery of function after total hip arthroplasty using performance-based tests: a prospective cohort study.

Purpose: The aim of this study was to evaluate the value of conventional factors, the Risk Assessment and Predictor Tool (RAPT) and performance-based functional tests as predictors of delayed recovery after total hip arthroplasty (THA).

Method: A prospective cohort study in a regional hospital in the Netherlands with 315 patients was attending for THA in 2012. The dependent variable recovery of function was assessed with the Modified Iowa Levels of Assistance scale.
