Increased tibial slope is reported as a risk factor of noncontact anterior cruciate ligament ACL injury but the effect of the soft tissues on slope remains unclear The primary aims of this study were to compare the tibial bony and soft tissue slopes between patients with and without ACL injury and to investigate the relationship between the meniscal slopes MS and the tibial bony slope Our hypothesis was that the menisci would correct the inclination of the bony tibial slope towards the horizontalUsing magnetic resonance imaging MRI the lateral and medial tibial slopes LTS MTS and lateral and medial meniscal slopes LMS MMS were compared in 100 patients with isolated ACL injury and a control group of 100 patients with patellofemoral pain and an intact ACLRepeatedmeasures analysis of variance showed good inter and intraobserver reliability for both bony and soft tissue slopes ICC 088–093 and 078–091 for intra and interobserver reliability respectively The LTS and MTS were significantly greater in the ACL injury group 104 ± 31 and 94 ± 33 than in the control group 73 ± 34 and 70 ± 37 Similarly the LMS and MMS were significantly greater in the ACL injury group 47 ± 47 and 60 ± 34 than the control group 09 ± 48 and 37 ± 36 In both groups the lateral bony tibial slope was greater than the medial bony tibial slope but the medial soft tissue slope was greater than the lateral soft tissue slopeIncreased tibial slopes both bony and meniscal are risk factors for ACL injury As the meniscus tends to correct the observed slope towards the horizontal loss of the posterior meniscus may potentiate this effect by increasing the functional slope
