Large acetabular defects remain a challenge in hip revision arthroplasty. Experience with Trabecular Titanium¿ (TT) cups (Limacorporate S.p.a.) has not been widely reported. Therefore, we assessed the survivorship and clinical and radiological outcomes of patients receiving TT cups, with or without supplementary trabecular titanium hemispherical modules for acetabular reconstruction, in primary and revision total hip arthroplasty (THA).~Background~Background~Between January 2009 and July 2014, we performed 67 revisions and 5 primary THAs using TT cups in 69 patients. To achieve stability and/or restore the hip's centre of rotation, hemispherical modules were used in 17 cases based on preoperative templating and/or intraoperative findings. Mean follow-up was 30.5 months. Acetabular bone defects were classified according to the Paprosky classification. Survivorship, functional outcomes (Merle d'Aubigné) and radiological outcomes were analysed.~Methods~Methods~8 patients underwent cup revision: 2 for loosening, 3 for infection, and 3 for hip dislocation. The remaining cases did not present radiological signs of loosening. None of the cases with Paprosky type I classifications needed revision, while 4 with type II and 4 with type III needed revision (p = 0.028). The respective mean values for pain, walking, and range of motion (Merle d'Aubigné scores ± standard deviation) were 3.6 ± 1.4, 3.7 ± 0.7, and 3.8 ± 0.6 preoperatively, and 5.7 ± 0.7, 5.3 ± 0.7, and 5.6 ± 0.7 at the latest follow-up (p<0.001).~Results~Results~In the short term, results with TT cups appear to be encouraging, with satisfactory survival rates for both simple and complex cases.~Conclusions~Conclusions [ABSTRACT FROM AUTHOR]

Background: 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.Methods: 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.Results: 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.Conclusion: 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.
