The Role of Highly Selective Implant Retention in the Infected Hip Arthroplasty.

CONCLUSIONS: In some patients, staged revision of large and well-fixed components will result in bone damage and compromised function. These results suggest that partial implant retention and joint débridement may be an alternative for those patients who have complex well-fixed acetabular or femoral components, are not immunocompromised, have not developed sinus formation, and we were able to obtain a positive hip aspirate. We caution this technique should not be applied when patients have chronic illness such as diabetes or rheumatoid disease, have a negative hip aspirate for microorganisms, or show any signs of loosening on radiography, CT, or on intraoperative assessment. These results at a minimum of 5 years are reassuring in this small single-center series, but we suggest that the technique not be widely adopted until or unless larger groups of patients with longer term data have been studied. LEVEL OF EVIDENCE: Level IV, therapeutic study. PMID: 27334323 [PubMed - as supplied by publisher]
