Abstract

Background: The anterior cruciate ligament (ACL) runs from the femur to the tibia in the knee joint and is a thick band of connective tissue that may be exposed to tears. Accurate MR imaging evaluation of these patients requires an understanding of the usual postoperative MR imaging appearance of postoperative ACL graft and any abnormalities.
Objective: To assess the complications and associated findings by conventional MRI in post-operative ACL reconstruction.
Patients and methods: This study included 27 symptomatic patients (23 males and 4 females). The study was carried out at the Radiology Department at Zagazig University Hospitals. They were assessed by conventional MRI after the ACL operations.
Results: The mean age of the studied patients was 29.26 ± 7.79 years old. Most of the studied patients were males (85.2 %). 14.8% of the studied patients had anterior tibial translation, graft impingement in 2/27 (7.4 %) of patients and anteriorly displaced tibial hardware was found in 3/27 (11.1 %) of the studied patients. 18.5% of the studied patients had joint effusion. PCL buckling and bone marrow edema were found in 7.4% of the studied patients and PHMM degeneration was found in 11.1% of the studied patients.
Conclusion: In order to properly evaluate the post-operative knee, particularly in patients who had cruciate ligament repair, magnetic resonance imaging (MRI) of the knee is required.
