Table 3 Correlation coefficients between cyst parameters and patient and clinical OA characteristics over the total proximal tibia. Spearman’s correlation coefficient was used for all variables. For alignment, negative relationships represent associations with varus alignment while positive relationships represent associations with valgus alignment. Significant associations are marked

From: Knee osteoarthritis patients with more subchondral cysts have altered tibial subchondral bone mineral density
