The efficacy of topical preparations in reducing the incidence of Cutibacterium Acnes at the start and conclusion of total shoulder arthroplasty (TSA)

Traditional skin preparation for total shoulder arthroplasty (TSA) is not specific for Cutibacterium acnes (C. Acnes) Topical Benzyl Peroxide (BPO) and Benzyl Peroxide with Clindamycin (BPO/C) has been shown to reduce the bacterial load of C. acnes on the skin. Our aim was to investigate whether preoperative application of these topical antimicrobials reduce superficial colonization and deep tissue inoculation of C. Acnes in patients undergoing total shoulder arthroplasty.
