Meniscal grade by collapsed meniscal grading scheme. The table illustrates the distribution of subjects by meniscal grading schemes and KL grade. Each column shows the number of subjects assigned to the meniscal grade. The percentage in parenthesis represents the percentage of subjects in each KL grade that have a given meniscal grade. Controls are defined as subjects having a KL score of 0, Mild OA are defined as subjects with a KL score of 1 or 2, and Severe OA are defined as subjects having a KL score of 3 or 4.
