Figure 1.

Radiographs of the largest tunnel enlargements measured after ACLR. The widest femoral tunnel diameter measurement was taken at the sclerotic margins of the bone. The same was done at the tibial tunnel. The Armorlink (Orthopediatrics Corp., Warsaw, IN) implant is visible at the tibia. Growth arrest lines are straight and well-defined, indicating no growth disturbance. Lateral left knee radiograph 13year-old boy with initial and final femoral tunnel sizes of, respectively, 7.5 mm and 11.2 mm. Anteroposterior left knee radiograph 13-year-old boy with initial and final tibial tunnel sizes of, respectively, 7.5 mm and 12 mm.
