Femoral condyles	24	0.89^A	0.26	4.3^A	1.0
Patellar groove	17	1.32^B	0.26	4.0^A,B	1.1
Tibial plateau meniscus covered	31	1.10^A,B	0.38	3.8^A,B	1.1
Tibial plateau not meniscus covered	27	2.19^C	0.67	3.3^B	1.2

The letters^{A, B, C} are used to indicate significant differences between the different regions; where a region does not share a letter they are significantly different (p < 0.05).
n: number of samples tested from each region.
