Abstract
BACKGROUND:
The extent of the association between vitamin D deficiency and knee osteoarthritis remains inadequately understood.
OBJECTIVE:
This study aimed to elucidate the relationship between vitamin D levels and knee osteoarthritis through a cross-sectional analysis.
METHODS:
This retrospective study involved an analysis of knee radiographs and serum 25-hydroxyvitamin D3 (25-(OH) vitamin D3) levels in a cohort of 3424 individuals (2901 women and 523 men). Knee osteoarthritis severity was evaluated using the Kellgren-Lawrence radiological scoring system.
RESULTS:
Of the participants, 49.2% (
CONCLUSIONS:
The findings of this study indicate a higher prevalence of vitamin D deficiency in patients with knee osteoarthritis. Maintaining adequate serum 25-(OH) vitamin D3 levels may prevent knee osteoarthritis, especially in women below 65.
