title: Arthroscopic treatment of tibial spine malunion with resorbable screws.
abstract: Anterior tibial spine fractures are rare and were thought to occur mainly in children; however, recent literature indicates that the incidence in adults is much greater than previously thought. Because the tibial spine is an attachment point for the anterior cruciate ligament (ACL), an avulsion may produce ACL laxity, predisposing to further issues. We report the case of an 11-year-old boy with a tibial spine fracture that failed conservative management. He developed a malunion with impingement anteriorly of the tibial spine on the notch and residual instability of the ACL. In this report, we present a novel approach for arthroscopic reduction of a tibial spine fracture using 8 resorbable poly-L-lactic/polyglycolic acid nails.
