Purpose: To investigate the pre-soaking of hamstring grafts in topical vancomycin, in addition to IV prophylaxis, during anterior cruciate ligament (ACL) reconstruction to reduce the incidence of post-operative infection, and to describe an evidence-based diagnostic and treatment algorithm to facilitate early diagnosis and appropriate management of possible knee sepsis post-operatively after ACL reconstruction. Methods: This study is a controlled observational series comprising of 1585 individuals who underwent ACL reconstruction over a 13-year period. All surgeries were performed by a single surgeon at the same hospital. Group 1 consisted of 285 patients who received pre-operative IV antibiotics without topical graft pre-soaking. Group 2 consisted of 1300 individuals who received IV antibiotics and graft pre-soaking in a vancomycin solution of 5 mg/mL. Results: In group 1, a total of four patients suffered a post-operative joint infection (1.4 %). Three out of the four were culture positive for Staphylococcus species. The fourth was culture negative but was managed as an acute infection. Group 2 suffered no post-operative infections (0 %). Statistical analysis of the vancomycin pre-soak with IV antibiotics group, compared with IV antibiotics-alone group, revealed a significantly reduced post-operative infection rate using a Fisher’s exact test (P = 0.0011) and Chi-square test with Yates’ correction (P = 0.0003). Conclusions: Pre-soaking of hamstrings grafts with topical vancomycin reduced the rate of post-operative infection when compared to IV antibiotics alone. This technique should be utilised by surgeons to reduce the overall incidence of knee sepsis post-ACL reconstruction.
