Breakage of bioabsorbable femoral transfix screw after arthroscopic anterior cruciate ligament repair: a report of two cases

The reconstruction of anterior cruciate ligament (ACL) has become the standard of care for a torn ACL in active, young athletes. Various methods, graft options and techniques of reconstruction are published. The use of biotransfix bioabsorbable screw is one of the options of anchoring the graft on the femoral side. We describe the failure of transfix due to breakage in two patients after arthroscopic ACL reconstruction. These patients developed symptoms of screw irritation subcutaneously or skin penetration of the broken, migrated transfix pin. The clinical presentation, diagnosis, the image findings, management and review of literature are presented in this report. To the best of our knowledge, this is the only report from Asia.
