Investigating Whether Preoperative Use of Acne Face Wash for Cleansing the Face, Neck, and Chest Helps Reduce the Contamination Rate of Cutibacterium Acnes in Arthroscopic Rotator Cuff Repair Surgery

What this Trial Is About

Researchers are investigating whether using a 10% benzoyl peroxide (BPO) acne cleanser before arthroscopic rotator cuff repair surgery can reduce contamination by Cutibacterium acnes, a common bacteria that can remain after standard sterilization. Although prior studies showed the bacteria can persist in up to 30% of cases despite cleaning, evidence specifically for rotator cuff surgery is limited. This study aims to provide clear guidance on improving preoperative skin preparation for this type of shoulder surgery. Participants will be randomly assigned to one of two groups. The control group will cleanse the surgical area with soap or body wash following current routine practices. The experimental group will receive a 10% BPO acne cleanser and instructions to use it on the shoulder and surrounding skin during bathing the day before surgery. After surgical disinfection, skin samples and segments of surgical sutures will be collected for bacterial culture to compare contamination rates between groups. During the study, patients will follow preoperative skin cleansing instructions according to their assigned group. Researchers will collect skin and suture samples right after surgery to assess bacterial presence. The primary measurement is the bacterial culture result from sutures immediately after surgery. This prospective randomized design will help determine if BPO cleansing effectively lowers contamination and may influence future surgical preparation practices. Participation lasts through surgery and immediate postoperative sampling.
