The Relationship between Clinical and Radiological Signs of ACL Ligament after Reconstruction

Abstract

The aim of this study was to investigate the most important and valuable findings of MRI after the reconstruction of knee ACL that could help orthopedic patients in the plan of treatment. Materials and Methods: In this descriptive study, 25 symptomatic patients and 25 asymptomatic patients after knee replacement ACL were evaluated for 6 months after surgery. The presence of clinical signs such as knee instability, knee flexion, knee depression, lameness, new knee trauma, joint stiffness, and continuous pain were considered as the findings of the Lachman test and Pivot shift test positive. Surgical method in both groups of patients, the reconstruction of the anterior cruciate ligament is arthroscopic. MRI scans were anonymized by eliminating patients' complaints (symptom and asymptomatic) and MRI findings were evaluated by two experienced radiologists who were unaware of the complaints of patients. Results: The main findings of the MRI of the patients included: alteration, position change and tibial channel size, expected PCL change, ACL rupture, and articular fluid after the reconstruction of the knee ACL, which only occurred in the case group, in the case group in 10 patients (40%), he was taking edema, of which 3 (12%) were obviously edematous. In the control group, only 4 patients (16%) were observed. There was a significant difference between the two groups (p = 0.001).
