N2  - Background: Tunnelwidening after Anterior cruciate ligament (ACL) surgery can be measured byseveral radiological methods. Computed tomography (CT) and magnetic resonanceimaging (MRI) are used the assessment of tunnel widening in patient follow-up.The aim of our study is to analyse the reliability of tunnel width measuringbetween two different radiographic methods.Material and Methods: 24patients who were performed isoanatomic Arthroscopic Anterior Cruciate LigamentReconstruction by using hamstring autograft with elevator system in our clinicand had linear tunnel widening in their follow-up were included in the study.Five observers measured the tunnel width on sagittal, coronal and axial imagesof CT and MRI of the patients. Entrance, middle and out wide for the femoraland tibial tunnels were measured by each observer on these sections with aruler application on the PACS system (Picture Archiving and CommunicationSystem). The measurements were repeated with one week interval and themeasurements were documented by an independent surgeon.Results: 14significant differences in MRI measurements and 11 significant differences inCT measurements were seen in a total of 90 femoral measurements in all sections(p<0.05). 19 significant differences in MRI measurements and 11 significantdifferences in CT measurements were seen in a total of 90 tibial measurementsin all sections (p<0.05). Intraobserver reliability of femoral coronal,sagittal and axial sections was found 0.69 in MRI and 0.85 in CT, 0.41 in MRIand 0.77 in CT, 0.45 in MRI and 0.78 in CT, respectively. Intraobserver reliabilityof tibial coronal, sagittal and axial sections was found 0.66 in MRI and 0.81in CT, 0.38 in MRI and 0.69 in CT, 0.45 in MRI and 0.79 in CT, respectively.There was no significant difference between making the measurement of observerin the entrance, middle or out at femoral sections. The tibial measurementswere found to be higher number of incorrect measurements and lower reliabilitythan femoral measurements.Conclusions: As aresult, there is no difference whether making the measurement of tunnel fromentrance, middle or out in patients with liner widening, the using of coronalsection in measurements and if possible CT scan preference would give moreaccurate results. However, in later years the comparative studies withhigher-resolution MRI to measure the widening of the tunnel in case of similaror greater reliability with computed tomography, MRI will be more preferablewhen also we take into account of radioactive effects of CT.
