Table 3. Correlation between radiographic measures, Histologic Synovitis Grade and cranial cruciate ligament fiber damage.
| Radiographic Effusion | Radiographic OA | CrCLD | ||||
|---|---|---|---|---|---|---|
| SR | P value | SR | P value | SR | P value | |
| Complete CR Stifle | ||||||
| Histologic Synovitis Grade | -0.13 | 0.51 | -0.30 | 0.11 | -0.20 | 0.31 |
| Histologic Synovitis VAS | 0.02 | 0.91 | 0.02 | 0.93 | -0.13 | 0.51 |
| Partial CR Stifle | ||||||
| Histologic Synovitis Grade | 0.30 | 0.12 | 0.27 | 0.15 | -0.08 | 0.64 |
| Histologic Synovitis VAS | 0.38 | 0.04 | 0.47 | 0.01 | -0.12 | 0.54 |
| Arthroscopic Fiber Damage VAS | 0.30 | 0.11 | 0.61 | 0.0005 | -0.30 | 0.11 |
Note: Arthroscopic fiber damage VAS assesses ligament fiber rupture in the cranial cruciate ligament in the partial CR stifle. n = 29 dogs. Abbreviations: CR, cruciate ligament rupture; CrCL, cranial cruciate ligament; CrCLD, radiographic length of the CrCL normalized to patellar length.
