Outcome after reinfection following reimplantation hip arthroplasty.
Between 1976 and 1992, reinfection developed in 34 patients treated for an infected total hip arthroplasty with removal of the prosthesis and implantation of another prosthesis. These patients included 15 men and 19 women with a mean age of 62 years. Infection recurred an average of 2.2 years after reimplantation of the new prosthesis. Followup after the diagnosis of reinfection averaged 5.1 years. Reinfection after an attempt at reimplantation total hip arthroplasty was seldom compatible with a good functional outcome. Resection arthroplasty was reliable in eradicating reinfection but led to poor function and was associated with persistent pain. Although reimplantation of a third prosthesis allowed 3 patients to achieve an excellent result, the 8 hips that failed a third reimplantation attempt had the worst functional results in this study. The results from the present series suggest that reinfection after an attempt at reimplantation is a contraindication to further attempts at a 1-stage reimplantation of another prosthesis. Those patients in whom the same single microorganism has been identified from the failed primary total hip and from the failed first reimplantation, however, may be reasonable candidates for an attempt at a 2-stage reimplantation of a third prosthesis, particularly when a deficiency in prior antibiotic therapy or surgical technique can be identified.
