Table 2 Cyst parameters for study sample (n = 42), mean ± SD (median, range). Cysts were present in 88% of participants (37/42). Of the 37 participants with subchondral cysts, 33 had cysts medially and 18 had cysts laterally. For these reasons, in some cases the median value is 0. Cyst parameters specific to the 37 participants with subchondral cysts can be found in Additional file 3: Table S3
