Background: The purpose of this case report was to investigate the incidence of departmental infections following arthroscopic rotator cuff repair over a three-year period as well as to compare the clinical efficacy of treating postoperative infections following rotator cuff repair using incisional debridement sutures, arthroscopic shoulder debridement and lavage treatment, and arthroscopic debridement and lavage in combination with antibiotic-cement beading. Case presentation: A retrospective evaluation of 600 shoulder arthroscopic rotator cuff repairs performed in our hospital between 2021.1 and 2023.12 was conducted to screen the data of six Chinese women aged 51-71 years, who completed routine hematological and radiological examinations after admission, were treated with antibiotics, and the use of antibiotics was adjusted according to the results of wound secretion culture. Among them, 2 cases were treated with arthroscopic debridement and irrigation of the shoulder, 2 cases were treated with arthroscopic debridement and irrigation of the shoulder combined with antibiotic cemented nails, 1 case was treated with incision and debridement and suture, and 1 case was treated conservatively. Postoperative anti-infective treatment with antibiotics was continued, and the relevant indexes were rechecked. Preoperative and postoperative follow-up were performed using the visual analog scale (VAS) and the American Shoulder and Elbow Surgeons (ASES) score. Results: The infection rate of patients who underwent rotator cuff repair during the evaluation period was 1%. Culture of wound secretions from six infected patients showed culture results of Staphylococcus aureus, Serratia marcescens, Mycobacterium xylosoxidans colorless, and Mycobacterium tuberculosis, with no obvious abnormalities, and no cultures were performed. Two cases were treated with shoulder arthroscopic debridement and irrigation, two cases were treated with shoulder arthroscopic debridement and irrigation combined with antibiotic bone cement beading, one case was treated with incision and debridement and suturing, and one case was treated conservatively. At the final follow-up, the scores of two patients treated with arthroscopic debridement and irrigation of the shoulder improved, two patients treated with arthroscopic debridement and irrigation of the shoulder combined with antibiotic-cemented beading did not show significant improvement, one patient treated with incisional debridement and suturing improved significantly, and one patient treated conservatively improved significantly. Conclusion: The overall infection rate of arthroscopic rotator cuff repair of the shoulder over 3 years was 1% (6/600). The use of incisional debridement and suturing or shoulder arthroscopic debridement and irrigation has better clinical outcomes than shoulder arthroscopic debridement and irrigation combined with cement beading for the treatment of infection after arthroscopic rotator cuff repair.
