Anterior cruciate ligament (ACL) rupture is a common condition often treated with an allograft reconstruction. In this case, a patient presented 2 months post-ACL allograft reconstruction with acute knee synovitis. Initially, it was assumed to be septic arthritis; however, based on magnetic resonance imaging, pathology, serology, and cultures, his acute synovitis was believed to be due to a host mediated immune response.
