Two-stage revision total hip arthroplasty (THA) is the most commonly used treatment approach for deep prosthetic infection. However, in this approach the interval between the first and second stage tends to be prolonged. We devised a strategic protocol for improving the infection eradication rate and shortening the interval between the stages in two-stage revision THA. This study analyzed a series of 14 patients (14 hips) from 2008 to 2012, who were treated using an antibiotic-loaded acrylic cement (ALAC) spacer at the first stage and re-implantation at the second stage. The ALAC included vancomycin and amikacin for most of the cases. Patients with MRSA infection were additionally administered intravenous vancomycin in combination with either oral rifampicin or trimethoprim-sulfamethoxazole. The average interval between the stages was 54.2 days overall, and 58.7 days for cases with MRSA infection. Our infection eradication rate was 100%, with no reported recurrence of infection. The presence of MRSA tended to be associated with a longer interval between the two stages. Our protocol for two-stage revision THA was associated with a high eradication rate of infection and a shortened interval between the stages.
