Knee cartilage defects in a sample of older adults: natural history, clinical significance and factors influencing change over 2.9 years J. Carnes, O. Stannus, F. Cicuttini, C. Ding, G.

Fig. 1 Change in knee cartilage defect scores by site over 2.9 years (A) Increase/stable/decrease percentages by compartment were 34.0/64.2/1.8% for the medial tibiofemoral compartment, 32.0/64.9/3.1% for the lateral tibiofemoral compartment, and 25.8/73.2/1.0% for the patellar compartment. Total score was calculated by summing medial tibiofemoral, lateral tibiofemoral and patellar scores. (B) Average cartilage defect scores increased significantly in all compartments over 2.9 years (medial: 2.22 vs 2.65, lateral: 2.06 vs 2.39, patellar: 1.59 vs 1.84, total: 5.86 vs 6.89). Error bars are 95% CIs, * = P < 0.001.
