Preoperative demographic data for patients with at least 10° preoperative varus by postoperative alignment
| Variable | Residual varus | Neutral alignment | Significance |
|---|---|---|---|
| Gender (males:females) | 41:90 | 52:79 | p = 0.20 |
| Age (years) | 72.2 ± 7.5 | 72.8 ± 6.3 | p = 0.51 |
| BMI (kg/m2) | 31.0 ± 5.9 | 28.8 ± 5.2 | p = 0.0019 |
| Preoperative FTMA (°) | 165.2 ± 3.9 | 167.8 ± 2.4 | p < 0.0001 |
| Preoperative TMA (°) | 82.8 ± 3.6 | 83.8 ± 4.2 | p = 0.058 |
| Preoperative FMA (°) | 88.9 ± 2.8 | 90.0 ± 2.2 | p = 0.0009 |
| Preoperative IKS score (points) | 86.6 ± 30.9 | 96.9 ± 29.5 | p = 0.0064 |
Values are expressed as mean ± SD; BMI = body mass index; FTMA = femorotibial mechanical axis; FMA = femoral mechanical angle; TMA = tibial mechanical angle; IKS = International Knee Society.
