Table 2.

Odds ratios for the association of baseline mean and peak contact stress with (a) cartilage worsening and (b) BML worsening by 30-month follow-up. (N= 38 knees)

Cartilage Worsening BML Worsening
OR (95% CI) p-value OR (95% CI) p-value
Mean contact stress 4.0 (2.5, 6.4) <.0001 6.6 (2.7, 16.5) <.0001
Peak contact stress 1.9 (1.5, 2.3) <.0001 2.3 (1.5, 3.6) <.0001
