Title: Orthopedics, Low Back Pain, and Rehabilitation Poster

Session Type: Poster Session B

Session Time: 9:00AM-10:30AM

Background/Purpose: Recent literature suggests that rheumatic disease patients hold most immunosuppressive (IS) medications before and after joint replacement surgery, to prevent infections and other complications. But there are currently no guidelines on peri-arthroscopic management of IS treatment in this population. The purpose of this study is to characterize the rheumatic disease patient population undergoing arthroscopy, compare the incidence of postoperative complications among patients who either remained on IS perioperatively, held IS perioperatively or were not on IS at baseline, and compare the incidence of postoperative complication by rheumatic disease type, medication type, and procedure.

Methods: We conducted a retrospective review of all arthroscopic sports medicine surgeries in patients with a rheumatic disease diagnosis at our institution over an 11-year period. Patients on IS at baseline were grouped into those who remained on IS perioperatively or held all IS before the date of their surgery. These two groups were compared to rheumatic disease patients who were not on IS at baseline. Incidence of postoperative complications was calculated for the three cohorts and by medication class, rheumatic disease type, and procedure risk. Analysis of variance (ANOVA), Chi-squared, and Fisher’s exact tests were used to determine the statistical significance of between-group differences in postoperative complication incidence.

Results: We identified 1,316 rheumatic disease patients undergoing arthroscopy, with 214 of them taking IS medications at baseline. Overall, 8.4% (n=110) remained on IS perioperatively, 7.9% (n=104) held IS perioperatively, and 83.7% (n=1102) were not on IS at baseline. In all cohorts, 7 patients experienced postoperative complications, with 6 of the 7 due to infections. There were two cases (1.82%) of infections among patients remaining on IS perioperatively, zero cases (0%) of infection in patients who held all IS, and four cases (0.36%) of postoperative infection in patients who were not on any IS at baseline. There was no statistically significant difference in postoperative infections or complication rates among the three cohorts or further subgroups.

Conclusion: Physicians and surgeons will increasingly be faced with challenging perioperative management decisions regarding IS in their rheumatic disease patients undergoing arthroscopic surgery. The present study is the first to suggest a low and acceptable risk of postoperative infections and other complications in these patients on IS at the time of arthroscopy.

All abstracts accepted to ACR Convergence are under media embargo once the ACR has notified presenters of their abstract’s acceptance. They may be presented at other meetings or published as manuscripts after this time but should not be discussed in non-scholarly venues or outlets. The following embargo policies are strictly enforced by the ACR.

Accepted abstracts are made available to the public online in advance of the meeting and are published in a special online supplement of our scientific journal, Arthritis & Rheumatology. Information contained in those abstracts may not be released until the abstracts appear online. In an exception to the media embargo, academic institutions, private organizations, and companies with products whose value may be influenced by information contained in an abstract may issue a press release to coincide with the availability of an ACR abstract on the ACR website. However, the ACR continues to require that information that goes beyond that contained in the abstract (e.g., discussion of the abstract done as part of editorial news coverage) is under media embargo until 10:00 AM ET on November 14, 2024. Journalists with access to embargoed information cannot release articles or editorial news coverage before this time. Editorial news coverage is considered original articles/videos developed by employed journalists to report facts, commentary, and subject matter expert quotes in a narrative form using a variety of sources (e.g., research, announcements, press releases, events, etc.).

Violation of this policy may result in the abstract being withdrawn from the meeting and other measures deemed appropriate. Authors are responsible for notifying colleagues, institutions, communications firms, and all other stakeholders related to the development or promotion of the abstract about this policy. If you have questions about the ACR abstract embargo policy, please contact ACR abstracts staff at [email protected].
