Infection after total hip arthroplasty is a severe complication. Controversies still exist as to the use of cemented or uncemented implants in the revision of infected THAs. Based on the data in the Norwegian Arthroplasty Register (NAR) we have studied this topic. During the period 2002–2008 45.724 primary THAs were reported to NAR. Out of these 459 were revised due to infection (1,0%). The survival of the revisions with uncemented prostheses were compared to revisions with cemented prostheses with antibiotic loaded cement and to cemented prostheses with plain cement. Only prostheses with the same fixation both in acetabulum and in femur were included in the study. Cox-estimated survival and relative revision risks were calculated with adjustments for differences among groups in gender, type of surgical procedure, type of prosthesis, and age at revision.Introduction
