In the first two years following total hip arthroplasty (THA), the true rate of hip dislocation is 3.5 percent, according to the report by Lars L. Hermansen, MD, of Hospital of South West Jutland, Esbjerg, Denmark, and colleagues. Since our results are based on a large cohort over a five-year inclusion period and include all hospital contacts in Denmark within the first two years after THA, we believe to have found the true occurrence of dislocation within this patient group and time frame, the researchers write. Comprehensive approach needed to capture true risks of dislocation after THA
Hip dislocation is a common and devastating complication following THA and is one of the leading reasons for revision. Previous studies have reported widely varying rates of dislocation following THA, reflecting differences in study methods and patient populations. Some dislocations may be treated without a surgical procedure or hospital admission; other patients may undergo revision at a
