    Introduction: Osteoarthrosis (OA) is the most common chronic injury due to soccer, and the knee is one of the most affected regions. More recent studies cite a relation between anatomical features, such as the inclination of the tibial plateaus (tibial slope, TS), and the genesis of ostearthrosis of the knees. Objectives: To evaluate the association of posterior slope of the tibial plateau and diagnosis of osteoarthrosis on radiography and severity of osteoarthrosis on magnetic resonance imaging in former retired professional soccer players. Methods: crosssectional study with 27 former retired professional soccer players and 30 recreational sports individuals. The diagnosis of OA was based on the KellgrenLawrence classification (KL), on the radiographs. The severity of OA was determined by WORMS (WholeOrgan Magnetic Resonance Imaging Score) classification. The TS measurement was performed by Hudek's method(2) on magnetic resonance imaging (MRI). Mean values of WORMS, TSL, TSM, Delta TS (difference between TSL and TSM values) were compared between groups, and between individuals with arthrosis and without arthrosis for both knees. Based on the study of Hudek et al.(2), cutoff values of 9 degrees for TSL and 7 degrees for TSM were established, and mean values of WORMS values were compared in individuals with slopes higher than cut values with the others, in the control and explayers, with osteoarthrosis and without osteoarthrosis, to both knees. Results: Former players with TSL greater than 9 in the dominant knees presented WORMS significantly higher in relation to the other individuals. Conclusion: Greater values of posterior inclination of the lateral tibial plateau of the dominant knees of explayers are related to the greater severity of osteoarthrosis in MRI. More studies are needed to establish correlation of TS and the genesis of osteoarthrosis in nonsports or recreational sports subjects.
