Table 4: Grades of Aggrecan Immunolocalization

Normal 12F Normal 39F Normal 43M OA 42M OA 49F OA 54F OA 55M OA 58F OA 65F OA 66F OA 70F
GradeT 0 1 1 2 3 2 1 2 3 2 3
GradeH 0 0 1 2 3 3 3 4 4 2 2

GradeT – Transverse section grade; GradeH – Horizontal section grade; Ages are listed in years; M = male, F = female. The difference of the grades between OA group and normal control group was statistically significant (p = 0.013).
