Summary. There is little knowledge in surgeons about the guidelines for prophylactic antibiotics in patients with prosthetic joints when undergoing a dental procedure. This study confirms this and there is need for robust and universal guidelines given the disastrous nature of prosthetic infection. Introduction. Infection as an indication for revision has increased to 12 % of the total revisions (NJR 9. th. report). However, it is next to impossible to find out the cause for a delayed prosthetic infection. With increasing number of arthroplasty procedures, is there a need for prophylactic antibiotics in patients with prostheses?. Methods. At London Knee Meeting 2012, a total of 163 surgeons were asked to take part in a survey. This was to find out if they knew of any existing guidelines for prophylaxis for dental procedures, if there was a need to practice more uniformly, and if they recommend such prophylaxis to their patients routinely. The grade of the surgeon and their experience in years was also noted. Results. Among the 163 surgeons who participated, 102 (62.6%) were arthroplasty surgeons. Of these, 73 (71.5%) were consultants with 3 or more years of experience. For this study, responses from these 102 surgeons were taken into consideration. Out of the 102 surgeons, only 39 (38%) were aware of AAOS recommendations. However, only 26 (25.5%) felt the need for such prophylaxis, other 37 (36%) were not sure if such prophylaxis was necessary. The remaining 39 (38.5%) did not think the prophylaxis was necessary. There was no difference found in the responses between the consultant and non-consultant surgeons. Conclusions. From this survey, it is clear that there is no uniformity of the knowledge of existing recommendations for prophylaxis of such patients with prostheses. There is probably a need to develop robust guidelines for prophylaxis, given the devastating nature of an infected prosthesis

Objectives

To review the current best surgical practice and detail a multi-disciplinary approach that could further reduce joint replacement infection.
