title: Transcutaneous migration of a tibial bioabsorbable interference screw after anterior cruciate ligament reconstruction.
abstract: We present a case of a poly-L-lactic acid (PLLA) tibial bioabsorbable interference screw disengaging and migrating transcutaneously 12 months after successful anterior cruciate ligament reconstruction with quadrupled hamstrings autograft. No graft insufficiency or joint inflammatory reaction was present. The screw was removed surgically with no evidence of resorption. The graft was well incorporated into the tibial tunnel. The patient recovered without difficulties and returned to her preinjury level of activity. To our knowledge, this is the first case reported of disengagement and extrusion of a PLLA bioabsorbable interference screw.
