MRI reveals how ACL grafts change shape after surgery

This study used MRI scans to look at how hamstring tendon grafts used to replace a torn anterior cruciate ligament (ACL) heal and change shape over a year after surgery. Researchers checked for ballooning (enlargement of the bone tunnels) and ligamentisation (how the graft turns into a ligament-like tissue). 24 adults who had ACL surgery at least one year earlier took part. The goal was to better understand the healing process, not to test a new treatment.
