Intraoperative kinematics according to the presence of isolated lateral or medial + lateral bone bruise
| Extensive-generalized isolated lateral bone bruise (n = 9) | Extensive-generalized bicompartmental bone bruise (n = 7) |
Rank-biserial correlation | p value | |
|---|---|---|---|---|
| IE 30 (°) | 21.6 ± 5.7 | 28.7 ± 3.6 | 0.6 | 0.012* |
| IE 90 (°) | 22.4 ± 8.5 | 32.7 ± 3.7 | 0.7 | 0.003* |
| PS IE (°) | 21.0 ± 3.2 | 23.6 ± 3.5 | 0.4 | n.s. |
| PS ACC (mm/s2) | 569.1 ± 151.7 | 613.6 ± 196.1 | 0.2 | n.s. |
Lateral or medial bone bruise means bone bruise on femoral, tibial, or both compartments. Isolated lateral bone bruise means ICRS grade 3–4 only on the lateral compartment. Bicompartmental bone bruise means ICRS grade 3–4 on both medial and lateral compartment. Data are presented as mean and standard deviation. Asterisks represent statistically significant differences (p < 0.05). n.s. means non-significant differences (p > 0.05)
