Revision Surgery for Shoulder Infection after Arthroscopic Rotator Cuff Repair: Functional Outcomes and Eradication Rate-A Systematic Review.

ABSTRACT

The outcomes after arthroscopic rotator cuff repair (RCR) have been reported to be successful. The incidence of deep infections (defined as an infection involving any part of the anatomy other than the skin and subcutaneous tissue) after surgery ranges between 0.03% and 3.4%. This systematic review aims to investigate the outcomes of revision surgery for infection following arthroscopic RCR. Clinical outcomes and eradication rates among patients treated with different surgical and antibiotic therapies are analyzed. A total of five studies were eligible for systematic review. A total of 146 patients were treated and evaluated, of whom 71 (48%) and 75 (52%) underwent arthroscopic and open surgery to manage the infection, respectively. The most common causative bacterium was Cutibacterium acnes (50.4%). Two studies reported the pre-and postoperative ASES score and Constant-Murley score (CMS), and a statistically significant improvement was found after surgery (p < 0.001 for both). Eradication was observed in a total of 138 patients (94.5%); no difference was found between arthroscopic and open revision surgery (92.8% and 96%, respectively, p = 0.90). The frequency-weighted mean duration of the intravenous antibiotic therapy was 6.6 ± 5.4 days, while the overall mean duration of antibiotic therapy, considering intravenous and oral administration, was 43.5 ± 40 days. Patients with infection following arthroscopic RCR undergoing revision surgery experienced a high rate of eradication. A significant improvement in shoulder functionality and less residual pain can be expected.
