CEMENTLESS ONE-STAGE REVISION OF CHRONIC INFECTIONS IN HIP ARTHROPLASTY (CORIHA): CLINICAL OUTCOME OF THE CORIHA PROTOCOL IN 56 PATIENTS AFTER A MEAN FOUR-YEAR FOLLOW-UP PERIOD

Aim Our aim was to evaluate cementless one-stage revision in chronic periprosthetic hip joint infection. Method and patients The study was performed as a multicentre, proof-of-concept, observational study with prospective data collection. Inclusion of patients with a chronic periprosthetic hip joint infection (PJI) were followed by protocolled surgical treatment (cementless one-stage revision - the CORIHA protocol) at one of 8 participating departments of orthopaedic surgery between 2009 – 2014, and the patients enrolled in a 2-year follow-up program. A PJI were diagnosed based on adopted criteria from McPherson and Zimmerli. At the time of initiation of the study in 2009, the collaborating departments performed approximately one-fourth of all nationwide primary HJR and more than one-third of all revisions. In total 56 PJI patients with a median age of 72 years and a median pre-operative ASA score of 2 met the established eligibility criteria and accepted to participate; 31 (55%) were males.
