Tóm tắt

 The impact of the bone tunnel size relative to body size on clinical results in anterior cruciate ligament (ACL) reconstruction remains unclear. This study aimed to assess the morphological alteration of the tibial tunnel aperture and relationship between the tibial tunnel size relative to the proximal tibia among the tibial tunnel widening (TW) and clinical results following ACL reconstruction. This study comprised 131 patients who had undergone anatomical ACL reconstruction utilizing bone-patellar tendon-bone autografts. The morphology and enlargement of the tibial tunnel were examined via three-dimensional computed tomography 1 week and 1 year postoperatively. The anteroposterior (AP) and mediolateral (ML) positions were determined as a percentage relative to the proximal AP and ML tibial dimensions, respectively. Clinical assessment was conducted 2 years postoperatively. The association between the primary tibial tunnel size among TW and clinical outcomes was examined. The tibial tunnel significantly migrated posterolaterally. The ML diameter significantly widened
  however, the AP diameter did not exhibit widening. AP widening was associated with the AP diameter of the primary tibial tunnel (
