摘要Objective: To assess the relationship between knee alignment and subregional T1rho values of the femorotibial cartilage and menisci in patients with mild (Kellgren-Lawrence grade 1) to moderate (KL3) osteoarthritis (OA) at 3T.

Materials and methods: 26 subjects with a clinical diagnosis of KL1-3 OA were included and subdivided into three subgroups: varus, valgus, and neutral. All subjects were evaluated on a 3T MR scanner. Mann-Whitney and Wilcoxon signed rank tests were performed to determine any statistically significant differences in subregional T1rho values of femorotibial cartilage and menisci among the three subgroups of KL1-3 OA patients.

Results: Medial femoral anterior cartilage subregion in varus group had significantly higher (p < 0.05) T1rho values than all cartilage subregions in valgus group. Medial tibial central cartilage subregion had significantly higher T1rho values (p < 0.05) than lateral tibial central cartilage subregion in varus group. The posterior horn of the medial meniscus in neutral group had significantly higher T1rho values (p < 0.0029) than all meniscus subregions in valgus group.

Conclusion: There exists some degree of association between knee alignment and subregional T1rho ?values of femorotibial cartilage and menisci in patients with clinical OA.
