Tibial geometrical properties.

	Lean	Obese	𝑛
Tibial length (mm)	42.01 ± 1.02^*	40.10 ± 0.67
Tibial mass (g)	1.37 ± 0.19	1.27 ± 0.09	31
Cross-sectional area (mm^2)	5.42 ± 0.46	5.53 ± 0.28	178
Cross-sectional moment of inertia 𝐼𝑥𝑥 (mm^4)	3.40 ± 0.56	3.44 ± 0.44	2453
Body mass (g)	389.5 ± 32.7^*	807.5 ± 53.0

Values are means ± SD. ^*denotes statistically significant (P ≤ 0.05). 𝑛 denotes the sample size per group needed for the recorded differences to become statistically significant based on a power of 0.8.
