The objective of our study is to evaluate our preliminary results after changing from a 2-stage revision arthroplasty protocol to a 1-stage revision arthroplasty protocol using cementless arthroplasty for all patients with chronic infected hip replacements. Prospective study of all hip arthroplasties that were diagnosed with chronic infection and were treated using the 1-stage revision without taking into account the traditional criteria used to determine the use of a 1-stage revision was conducted. There were 2 main variables evaluated: infection control and costs. The definitive diagnosis of infection of the revision was determined using the criteria proposed by the Musculoskeletal Infection Society. The costs were calculated using average cost in USD, excluding social expenses, as described by Klouche (2010) for 1-stage or 2-stage revisions. Nineteen patients were included in the study and the infection was controlled in 18 patients. The total economic savings for our hospital for these 19 patients was 391.609 USD. This clinical success has led to an important change in our hospital in treating chronic infected hip replacements and an important cost reduction from an economic point of view.
