Methods: Between 1976 and 2003 at our institution, twenty-nine patients were treated with reimplantation of a total elbow prosthesis after a prior resection arthroplasty following a deep periprosthetic infection. Eleven of the twenty-nine patients had had at least one procedure performed on the elbow prior to the primary arthroplasty. The mean time interval between the resection arthroplasty and the reimplantation was 72.5 weeks. Patients were followed for an average of 7.4 years after the reimplantation. All patients were assessed clinically, and their medical records were retrospectively reviewed.

Results: The mean total Mayo Elbow Performance Score (MEPS) was 35.5 points (range, 15 to 60 points) before the reimplantation and 66.3 points (range, 20 to 100 points) postoperatively (p < 0.001). The most common infecting organism was Staphylococcus epidermidis, which was present in thirteen (45%) of the twenty-nine elbows, followed by methicillin-sensitive Staphylococcus aureus, which was present in seven (24%). The infection was not eradicated in eight elbows (28%).

Conclusions: Reimplantation of a total elbow prosthesis after a prior resection arthroplasty is a reasonable option for the treatment of infection. Improvement in function can be expected in most patients. However, the chance of the infection recurring and requiring additional revision surgery is high.
