Macroscopic assessment | Histologic assessment | |||
|---|---|---|---|---|
Chondropathy score | Menisci examination | Collagen networks | Content of proteoglycans | |
Based on | [4] | [3] | [5] | [5] |
Grading system | Grade 0 = normal → Grade 4 = severe chondropathy | Grade 1 = normal menisci → Grade 4 = degenerated menisci | Normal = homogen green, organized matrix of collagen → Pathologic = disrupted, less organized, green matrix of collagen | Grade 0 = minimal red staining → Grade 5 = strong red staining |
