We report a case of arthroscopic repair of anterior cruciate ligament (ACL) injury in an adolescent with open physes. The patient was an 11-year-old boy who had been injured by hyperextension of the knee while playing soccer. The Lachman test and anterior drawer sign (ADS) were positive at initial consultation. CT and MRI confirmed a tibial eminence avulsion fracture and partial injury of the ACL. Arthroscopic primary suturing was performed. A tibial eminence avulsion fracture (6mmx6mm) and partial tear of the postolateral bundle (PL) were evident, and the patient underwent arthroscopic pull-out suture fixation using No.2 Fiberwire® for the avulsion fracture, without drilling the proximal tibial physes, and suturing of the PL remnant using 3 No.2 Vycril®, respectively. At the final follow-up evaluation 2 years after the operation, physical examination showed a negative Lachman test, ADS and pivot-shift test without any complications, and the boy returned to the previous sport. Arthroscopic repair is one of the operative procedures available for tibial eminence avulsion fracture or ACL tear at the femoral attachment in adolescents with open physes.
