^*indicates associations where p<0.05

^†positive β indicates higher mean relaxation times for females

^‡positive β indicates higher mean relaxation times for individuals with concomitant meniscal or chondral injury or pathology

^§positive β indicates higher mean relaxation times for individuals in the cluster group with increases in inflammation and cartilage degradation
