Purpose: The effect of sagittal plane angle of the tibial tunnel on the severity of tibial intra-articular aperture expansion caused by iatrogenic re-reaming in anterior cruciate ligament (ACL) reconstruction using a modified transtibial technique is unknown. The purpose of this study was to compare the severity of intra-articular aperture widening at different angles (40°, 45°, and 50°) of the tibial guide (TG).
Materials And Methods: Ninety-seven patients who underwent modified transtibial ACL reconstruction were randomly allocated to TG 40°, 45°, and 50° groups. Intra-articular tibial aperture width (TW) and tibial tunnel length (TTL) were measured intraoperatively using an arthroscopic ruler and a depth gauge.
Results: The TG 50° group had significantly greater tibial aperture widening than the TG 40° group. There was a significant difference among TG 40°, 45°, and 50° groups and the percentage of knees with TTL <35 mm was 8%, 9% and 3%, respectively. There were 2 females with TTL <35 mm in TG 40° and 45° groups each. The average mediolateral length of the tibial plateau was 75 mm.
Conclusions: This study shows that the TG angle of 40° would reduce the severity of intra-articular aperture widening of the tibial tunnel compared to 45° or 50° in modified transtibial ACL reconstruction.

Purpose: This study sought to quantify the tunnel widening associated with quadriceps tendon (QT) autograft after anterior cruciate ligament reconstruction (ACLR) and compare it to bone-patellar tendon-bone (BTB) autografts.
Methods: A retrospective review of each ACLR performed at a single academic institution from 2011 to 2021 were reviewed. Subjects with repeat ipsilateral knee magnetic resonance imaging (MRI) studies performed after ACLR were included.

Scleroderma is an autoimmune condition of unknown aetiology with a range of manifestations, which can be limited to the skin or can extend to be multisystemic. It is characterised by fibrosis, microangiopathy and dysregulation of the immune system and commonly affects the oral cavity. Frequent oral and maxillofacial features include fibrosis of the face, circumoral furrows and reduced oral aperture.
