Table 1 The modified graft-to-bone histologic score
From: Remnants-preserving ACL reconstruction using direct tendinous graft fixation: a new rat model
Scoring criteria | 0 | 1 | 2 | 3 |
|---|---|---|---|---|
Fibrous interface width | Wide | Medium | Narrow | Direct contact with bone (no fibrous interface) |
Bony ingrowth | None | Mild | Moderate | Marked |
Cell density | Marked | Moderate | Mild | Minimal |
Giant cells | Lots of giant cells (> 10) | Giant cells moderately present (5–10) | Few giant cells (< 5) | No giant cell |
Angiogenesis | Minimal | On a localized part of the periphery | On the entire periphery | On periphery and center |
