Oosting E, Kapitein PJC, de Vries SV, et al. - This study was carried out to assess the added value of a measure of physical functioning to predict short-stay total hip arthroplasty (THA). Researchers applied retrospective data of 1,559 patients who had undergone an anterior THA procedure. They conducted logistic regression analyses to evaluate the predictive value of preoperative variables among which preoperative physical functioning by use of the Timed Up and Go test (TUG) for short stay THA (< 36 h). They used the receiver operating characteristic curve and Youden Index to characterize a cutoff point for TUG associated with short stay THA. The results demonstrated that the performance-based physical functioning, measured by the TUG, is correlated with short stay THA. This understanding will guide the decision-making process for the planning and expectations in short stay THA protocols with the advantage that the TUG is a simple and fast instrument to be carried out.
