Table 2 Scoring of histological sections to assess cellularity, vascularity, and collagen fiber organization
From: Percutaneous ultrasonic debridement of tendinopathy—a pilot Achilles rabbit model
Appearance | Description | |
|---|---|---|
Cellularity score | ||
0 | Normal | Presence of flattened cells in a linear pattern between fibers |
1 | Slightly abnormal | Some rounded cells present, slight increase in cellularity |
2 | Abnormal | Many rounded cells present, obvious increase in cellularity |
3 | Markedly abnormal | Mostly rounded cells present, much higher numbers |
Vascularity score | ||
0 | Normal | Presence of some vascular bundles parallel to collagen fibers |
1 | Slightly abnormal | Slight increase in number of vascular bundles |
2 | Abnormal | Increased number of vascular bundles |
3 | Markedly abnormal | Large increase in number of vascular bundles |
Organization score | ||
0 | Normal | Parallel collagen fibers of similar widths |
1 | Slightly abnormal | Some loss of fiber organization, some loss of linearity |
2 | Abnormal | Moderate loss of fiber organization, few linear regions |
3 | Markedly abnormal | Total loss of organization, no linear fibers |
