Table 2.

Increase of the size of the tibiofemoral subchondral bone areas (% per annum) in neutral, varus and valgus knees over the observation period

	Neutral		Varus		Valgus
	Mean	SD	Mean	SD	Mean	SD
Change MT	0.17	0.93	0.18	1.05	0.00	1.18
Change LT	0.14	1.15	0.29	0.98	0.14	1.09
Change Ratio MT/LT	0.01	1.27	−0.08	1.24	−0.15	1.18

Change cMF	0.06	1.13	0.67	1.87	0.03	1.12
Change cLF	−0.14	0.97	0.12	1.42	0.32	1.15
Change Ratio cMF/cLF	0.23	1.37	0.49	1.93	−0.27	1.67

SD = standard deviation, MT = Medial tibia, LT = lateral tibia, cMF = weight bearing medial femur, cLF weight bearing lateral femur. The longitudinal changes in cMF and cLF differed significantly between neutral, varus and valgus knees (ANOVA), but not those in MT and LT.
