Abstract
Summary and conclusion There has been an increase in the number of anterior cruciate ligament (ACL) reconstructions (ACL-R), likely attributed to the overall availability of surgeons capable of performing the procedure and the increased participation in sporting activities, which are prone to ACL injuries. The increased number of ACL reconstructions being performed has lead to an increased demand for postoperative knee evaluation when symptoms persist or recur after ACL reconstructive procedures. This study aimed to assess the efficiency of MRI in evaluation of post ACL reconstruction and complications such as tear, impingement, instability and perigraft fibrosis. The present study included 28 patients underwent ACL graft reconstruction; 26 of them were males while 2 of them were females. The age of our selected patients ranged from 20 to 50 years. All patients were subjected to the following: A-full history taking that included: The patient’s age and sex. Types and timing of the operations done. Complaints of the patient. History of trauma after the operation. B- Postoperative evaluation done by orthopedic surgeon. C-Radiological examination: I- Magnetic resonance imaging (MRI): All MRI studies (28 cases) were obtained using closed MRI machine intensity field1.5 T with dedicated knee coil. In our study 18 patients had intact ACL graft and 10 patients with ACL graft tear due to reinjury; 6 of them had complete ACL tear and 4 patients had partial graft tear. 5 patients had ACL graft impingement presented with graft
