Clinical outcome scores and MRI evaluation
bone edema
Demographic and clinical data including the patient’s age at the time of surgery, the presenting symptoms, range of motion and ligament stability assessed by the ACL ligament score (Lachman test) were collected. In addition, Tegner activity score and Lysholm score were evaluated preoperatively and at final follow-up after a minimum of 12 months.MRI evaluation was conducted with the INFINITT Healthcare PACS viewing software (Frankfurt am Main, Germany). Analysis included measurement of the thickness of the ACL (largest diameter on sagittal fat-saturated (fs) proton-density-weighted turbo spin-echo (PDw TSE) sequences), ratio of ACL (largest diameter of the ACL on axial PDw TSE) and intercondylar width, signal intensity of the ACL and presence of bone edema or intraosseous cysts (Fig. Measurement in the MRI of the MDACL: ratio of the ACL and intercondylar notch width on the axial view and ACL thickness on the sagittal view
