Changes in the mean positional coordinate of the peroneal tendons in the presence or absence of the CFL.
| Status of the CFL | P value | Δ | 95% CI | ||
|---|---|---|---|---|---|
| Intact | Detached | ||||
| PLT | |||||
| x | 40.8 ± 5.2 | 41.0 ± 5.6 | 0.59 | − 0.1 ± 1.1 | − 0.7 to 0.4 |

| x | 43.9 ± 5.6 | 44.2 ± 5.5 | 0.12 | − 0.4 ± 0.9 | − 0.8 to 0.1 |
| y | 21.1 ± 5.6 | 19.6 ± 5.4 | < 0.001 | 1.5 ± 0.9 | 1.0 to 1.9 |

The values are presented as the mean ± the standard deviation (mm). The difference (Δ) is calculated by subtracting the position when the calcaneofibular ligament (CFL) is detached from the position when the CFL is intact.
