Postoperative reaction and infection after anterior cruciate ligament (ACL) reconstruction is a rare complication. We report two cases of bioabsorbable screw extrusion and Pseudomonas aeruginosa tibial tunnel infection in 17/18-year-old men, 2 and 4 years after ACL reconstruction, respectively. They underwent tibial tunnel debridement, removal of the still intact poly-L-D-lactic acid bioabsorbable screw and subsequent wound closure. Physical examination findings confirmed patency of the hamstring graft. Culture guided antibiotics were completed, and wounds healed unremarkably. Both returned to previous level of activity. Successful treatment is achieved through a logical sequence of management, as well as a multidisciplinary approach to prevent unnecessary secondary procedures and morbidity.
