Purpose:
The aim of this study was to evaluate the results of one- and two-stage revision total hip arthroplasties (THAs) and to determine a rational surgical treatment strategy for periprosthetic hip infections.
Methods:
We constructed a 12-point preoperative scoring system to suggest either one- or two-stage revision THAs, based on a retrospective analysis of 55 operative procedures. Prosthesis survival was analysed using the Kaplan-Meier method, and the validity of the scoring system was evaluated using receiver-operating characteristic curves.
Results:
At the end point of implant removal due to recurrent infection, the ten year survival rates were 94 and 87% for one- and two-stage revision THAs, respectively. One-stage revision THA was recommended for patients scoring >9 points. The risk of recurrent infection in patients scoring 4 points was 83%. The sensitivity and specificity of a cut-off value of 4 points, determined by the scoring system, were 83 and 100%, respectively.
Conclusions:
The novel pre-operative scoring system was useful for the management of periprosthetic hip infections.
