MRI and arthroscopic findings in acute and chronic ACL injuries. A pictorial essay

Abstract

89 patients with an acute ACL tear and 103 patients with chronic (later than 6 months post-injury) tears. All arthroscopies were performed by a single orthopedic surgeon with years of experience, who had kept notes of the intraoperative findings. All arthroscopies were reviewed by another independent reviewer blind to the MR imaging reports. The percentage agreement between MRI and arthroscopic findings was assessed.
