To compare post-operative infection rates following ACL reconstruction performed with grafts pre-soaked in vancomycin versus those without vancomycin.A systematic review was performed using PRISMA guidelines. PubMed, SCOPUS, and Cochrane Central Register of Controlled Trials were searched for therapeutic level I-III studies that compared outcomes of pre-soaking ACL grafts with vancomycin versus without vancomycin in human patients. Included graft types were tendon autografts or allografts, and studies documenting infection with a minimum follow-up of 30 days were included. Postoperative infection rates and knee-specific patient reported outcome scores were extracted from each study and compared between groups. Study methodological quality was analyzed using the Methodological Index for Non-Randomized Studies (MINORS) and Modified Coleman Methodology Score (MCMS). Infection rates and re-tear rates were pooled and weighted for meta-analysis using a random-effects model. All P values were reported with an alpha level of 0.05 set as significant.The initial search yielded 144 articles (44 duplicates, 100 screened, 29 full-text review). Ten articles (21,368 subjects [7,507 vancomycin and 13,861 no vancomycin], 67% males, mean age 29.5 + 1.5 years old) were included and analyzed. Eight of the 10 studies included only autografts, with 94.5% of grafts being hamstring autografts. Soaking grafts in vancomycin resulted in significantly fewer infections (0.013% vs 0.77%; OR 0.07 [0.03, 0.18], p < 0.001). Only two studies included patient reported outcomes, and both demonstrated no difference in International Knee Documentation Committee (IKDC) scores one year after surgery for patients with grafts pre-soaked in vancomycin compared to without vancomycin.Soaking ACL tendon grafts with vancomycin prior to implantation is associated with a nearly 15 times decrease in odds of infection compared to grafts not soaked in vancomycin. There were few studies that investigated patient reported outcomes and re-tear rates after soaking ACL grafts in vancomycin.
