Abstract
Eighteen patients with periprosthetic joint infection (11 hips and 7 knees) treated by prosthetic articulating spacers retained their spacers and were followed up at an average of 43.8months(range, 13-78months). Fifteen patients maintained well-functioning spacers for an average of 42.7months, of which 4 patients died with the spacers in situ at an average of 48.7months. The mean Harris Hip Score and Knee Society knee and function scores of survivors were 92, 92, 88, respectively. Spacers were revised in 3 patients because of recurrent infection (n=1) at 24months and mechanical loosening (n=2) at 74 and 50months. Findings of this study suggest that a proportion of patients with unplanned retention of prosthetic spacers appear to function well up to 6years without necessarily requiring further surgical intervention.
