Comparison of Different Anterior Cruciate Ligament Surgery Techniques in Skeletally Immature Patients.

September 30, 2025 updated by: Martin Lind, Aarhus University Hospital

This cohort study compares to groups of patients with reconstruction of anterior cruciate ligament (ACL). Patients in group 1 had ACL-reconstruction in the years 2001-2010 with a transphyseal drilling technique. Patient in group 2 had ACL-reconstruction in the years 2013-2018 with a physeal sparing technique.

Data including: x-ray exam, patient reported questionnaires and clinical evaluation will be compared between the 2 groups.
