Longitudinal association between baseline effusion synovitis and cartilage status at 30 months follow-up
| Cartilage status at follow-up | ||||
|---|---|---|---|---|
| Synovitis and effusion at baseline (N=514 knees) | Total no of knees | Cartilage loss (%) | Crude OR (95% CI) | Adjusted OR* (95% CI) |
| Hoffa synovitis absence (grades 0 and 1) | 467 | 119 (25.5) | 1.0 (reference) | 1.0 (reference) |
| Hoffa synovitis presence (maximum grade ≥2) | 47 | 18 (38.3) | 1.4 (0.7 to 2.7) | 1.0 (0.5 to 2.1) p=0.89 |
| Effusion synovitis absence (grades 0 and 1) | 461 | 109 (23.6) | 1.0 (reference) | 1.0 (reference) |
| Effusion synovitis presence (maximum grade ≥2) | 53 | 28 (52.8) | 3.4 (1.9 to 6.2) | 2.7 (1.4 to 5.1) p=0.002 |
* Adjusted for age, sex, body mass index, malalignment and baseline effusion synovitis, Hoffa synovitis, patellofemoral cartilage damage, meniscus damage, meniscal extrusion and bone marrow lesions.
