Control of an outbreak of postoperative bone mucormycosis: An intervention study of contiguous cohorts.

An outbreak of postoperative bone mucormycosis following arthroscopic anterior cruciate ligament reconstruction in a tertiary referral center in Paraná, Argentina, could have been transmitted through an arthroscopic anterior cruciate ligament reconstruction-exclusive contaminated item. The outbreak was controlled after changing from a system of direct delivery of implants and instruments to the operating room without proper verification, to a controlled and centralized process; specifically, the institution's pharmacy verified the quality and traceability of implants, and instruments were processed only by the institution's central sterile services department.
