We reviewed all patients that suffered a deep infection following anterior cruciate ligament (ACL) repair kept between January 2007 and April 2011 at our teaching hospital NHS trust, and the two local private hospitals.

18 patients were identified. All patients underwent at least 2 arthroscopic washouts, with limited synovectomy if required. Targeted antibiotics were commenced according to the culture results, and following microbiological advice. These patients were reviewed at a minimum of 1 year following eradication of infection (range 12–46 months). There were 7 surgeons performing the ACL reconstructions.

The primary outcome measure was graft failure requiring revision. Our secondary outcome measures were a history of ongoing instability, KT 1000™ measurement, Tegner and Lysholm outcome scores. There were 18 patients identified as having suffered infection after ACL infection (mean age 24.3 years, range 15–38 years). Average C Reactive Protein (CRP) was 217 on admission (range 59–397). The most common organism isolated was coagulase negative staphylococcus in 47.3% of cases. There were 3 graft failures within the infection group. Of the remaining 15 patients there were no episodes of ongoing instability and mean pivot shift grade was 1.1, mean KT 1000™ side-to- side difference was +1.8mm. There was a reported drop on the Tegner activity score of 1.75 (range 0–6) and mean Lysholm score was 89 (range 56–100).

The failure rate is slightly higher than that reported in the literature. Patient reported outcome measures in the patients are broadly consistent. We recommend an aggressive approach to the treatment of deep infection following ACL reconstruction, in order to achieve a satisfactory outcome.
