Characteristics of patients with knee OA, according to femorotibial angle tertile group (n = 135). Patients with varus knee OA were classified into 3 tertile groups based on the femorotibial angle. Values are mean ± SD.
| Femorotibial Angle Tertile Group | p | |||
|---|---|---|---|---|
| Tertile 1, n = 45 | Tertile 2, n = 45 | Tertile 3, n = 45 | ||
| Femorotibial angle (°) range | 177.1 ± 1.6 | 181.5 ± 1.2 | 188.3 ± 3.7 | |
| 173.3–179.4 | 179.6–184.0 | 184.2–198.5 | ||
| Age, yrs | 70.0 ± 7.2 | 69.4 ± 7.7 | 72.2 ± 6.5 | 0.153 |
| Body mass index, kg/m2 | 23.1 ± 3.4 | 25.0 ± 3.7 | 25.8 ± 3.7 | 0.002 |
p values were estimated using one-way analysis of variance.
