| False positive knees (BS5-152 positive/MRI5-152 negative) | True negative knees (BS negative/MRI negative) | p Value | |
|---|---|---|---|
| Total number of knee joints | 37 | 91 | |
| Mean (SD) age at diagnosis of ONFH5-152 | 45 (14) (21–79) | 46 (14) (20–79) | 0.8195-150 |
| Sex (M:F) | 22:15 | 53:38 | 0.8995-151 |
| Other necrotic lesions of the knee on MRI5-154 | 8 | 8 | 0.0735-151 |
↵5-150 Mann-Whitney U test.
↵5-151 Fisher's exact probability test.
↵5-152 BS = bone scintigraphy; MRI = magnetic resonance imaging; ONFH = osteonecrosis of the femoral head.
↵5-154 Other necrotic lesions of the knee include the distal femoral metaphysis, proximal tibial metaphysis, tibial plateau, and patella.
