Objective:
To evaluate the relationship between patients' body mass index (BMI) and the degree of radiographic severity of knee osteoarthrosis.
Method:
117 patients with gonarthrosis were evaluated prospectively. The patients' BMI was calculated and their knee arthrosis was classified in accordance with the modified Ahlbäck criteria. Kruskal-Wallis analysis of variance (ANOVA) was used to evaluate the relationship between these two variables.
Results:
The group classified as Ahlbäck grade V had significantly higher BMI than the others.
Conclusion:
There is a direct relationship between BMI and the degree of radiographic severity of gonarthrosis. Obesity appears to be directly related to the progression of knee osteoarthrosis.
