Weighted means of the arthroscopic diastasis measurements in the coronal plane

Number of transected ligaments	Anterior incisura (range of means) (mm)	Posterior incisura (range of means) (mm)
Intact	1.4 (0.8–2)	2.1 (1.3–3.3)
One ligament	2.0 (1.4–3)	2.6 (1.6–3.6)
Two ligaments	2.4 (1.7–3.8)	3.3 (2.1–4.4)
Three ligaments	3.0 (2–5)	3.7 (2.4–5)
Syndesmotic instability value*	2.9 (1.6–4.7)	3.4 (2.4–4.4)

*The syndesmotic instability weighted mean value was calculated using the tibiofibular displacement values from those injury patterns that showed a significant difference from the intact state
