Impact of additional parameters on smaller femurs.
| Preparation (femur size–distal resection–box position) | Medial condyle |
Lateral condyle |
||||
|---|---|---|---|---|---|---|
| Maximal von Mises stress (MPa) | Percent change from small femur control | Percent increase vs average femur with same preparation | Maximal von Mises stress on lateral condyle (MPa) | Percent change from control | Percent increase vs average femur with same preparation | |
| Small femur control (small–8mm–neutral) | 1.598 | 0% | +43.6% | 1.452 | 0% | +44.3% |
| Increase distal resection (small–12 mm–neutral) | 2.102 | +31.4% | +86.0% | 1.748 | +20.4% | +68.6% |
| Lateralize box (small–8 mm–lateral) | 1.919 | +20.1% | +79% | 1.630 | +12.3% | +57.2% |
| Combineda (small–12 mm–lateral) | 3.489 | +118.3% | +203.3% | 1.549 | −6.7% | +54.6% |
a
Combined includes both increased distal resection depth and box lateralization.
