PF joint BMLs, knee cartilage volume, and cartilage defect scores (range 0\u20134) were measured using the Whole\u2010Organ Magnetic Resonance Imaging Score system at baseline and at 2.6 years.

Of those without PF joint BMLs at baseline, 20% of participants developed PF joint BMLs over 2.6 years. In multivariable analyses, a change in PF joint BMLs was deleteriously associated with a change in total knee pain (\u03b2\u2009=\u20090.67, 95% confidence interval [95% CI] 0.03, 1.31) and knee pain when going up\/down stairs (\u03b2\u2009=\u20090.24, 95% CI 0.04, 0.44) over 5 years. Baseline PF joint and tibiofemoral joint cartilage volume were protective for PF joint BMLs (relative risk [RR] 0.69, 95% CI 0.52, 0.90 for PF joint), while baseline PF joint cartilage defects were associated with an increase in PF joint BMLs (RR 1.73, 95% CI 1.38, 2.17) over 2.6 years.
