From: Alterative effects of an oral alginate extract on experimental rabbit osteoarthritis
Score | Description |
|---|---|
0 | Normal matrix and chondrocytes |
1 | Uneven cartilage surface with loss of metachromasia around the enlarged cartilage of superficial zone. No fibrillation chondrocyte clusters |
2 | Some surface erosion, fibrillation and small chondrocyte clusters in superficial zone decreased metachromasia extending to the deep zone |
3 | Deeper surface erosion with fibrillation extending into the deep zone, large number of chondrocyte clusters containing several cells, major degenerative changes and loss of metachromasia in the cartilage matrix |
