Fracture of the femoral tunnel after an anterior cruciate ligament reconstruction.

Fractures after anterior cruciate ligament (ACL) reconstructive surgery are rare. Patella fractures can occur as a complication after bone-patellar tendon-bone autografts, and few case reports of tibia fractures have been published. Although reports of femur fractures have been published, the causes are attributed to stress risers other than the femoral tunnel. To our knowledge, this is the first case report of a femoral tunnel serving as a stress riser after an ACL reconstruction with bone-patellar tendon-bone autograft. The patient's fracture resulted from minimal trauma and required surgical fixation.
