Anterior Cruciate Ligament Reconstruction Grafts: MR Imaging Features at Long-term Follow-up—Correlation with Functional and Clinical Evaluation

PURPOSE: To assess the presence of increased intrasubstance signal intensity within anterior cruciate ligament (ACL) grafts and to assess whether such signal intensity changes are correlated to clinical assessments of graft instability and patient function 4-12 years after ACL reconstruction. MATERIALS AND METHODS: Ethical permission and written informed patient consent were obtained. The study was HIPAA compliant. Forty-seven patients were …
