Abstract
Graft fixation using bioabsorbable interference screws in anterior cruciate ligament (ACL) reconstruction has become a common and standard procedure. Bioabsorbable implants are also referred to as biodegradable implants because they undergo hydrolytic degeneration. Complications are uncommon, and include cyst formation, abscess formation, fibroxanthoma, bone tunnel fracture, effusion, infection, screw breakage, and migration. Migration of bioabsorbable interference screws after ACL reconstruction is a rarely reported complication. Here, we present a case of intra-articular migration of femoral bioabsorbable screw. At arthroscopy, the whole femoral screw was observed lying in the intercondylar notch and completely removed under the assistance of arthroscopy. The symptoms resolved postoperatively at 1-year follow-up. Recognition and adequate management of bioabsorbable screw migration may prevent associated morbidities.
