Risk Factors for Dislocation after Total Hip Arthroplasty: Results of a Long Term Analysis
A wide variable prevalence of dislocation after total hip arthroplasty (THA) has been reported, partly because of the variable lengths of follow-up for this specific endpoint. The effect of patient demographic factors on long-term risk of dislocation as a function of time after THA has not been well understood. The purpose of this study was to determine the risk of dislocation following cemented Charnley total hip arthroplasty with a 22 mm head size as a function of time and to investigate the patient demographic factors that influence the cumulative dislocation risk and time dependency of dislocation risk.
