Hospital readmission rates following primary total hip arthroplasty: present and future in sight

The number of total hip arthroplasties has been rising last decades, and it’s going to be more for futures decades. Coxarthrosis is the most common diagnosis that led this procedure and it is well known that it is growing in prevalence with the progressive aging population. In 2020 it was estimated that 18.2% of US Americans will be diagnosed with arthritis (1). About 10% of patients, who were undergoing total hip arthroplasty, will require the same procedure in the contralateral hip the following year. This percentage rises to 20% in the next 5 years, making a total of 42% of the patients who were undergone bilateral total hip arthroplasty (2). In view of the data, we are faced with a common procedure with growing interest. The readmission rate published to date is around 3.65% (3).
