| Summary: | Abstract Background Knee osteoarthritis (OA) is a prevalent condition influenced by various biochemical, anatomical, and lifestyle factors. Vitamin D deficiency has been implicated in OA, but its role in disease severity and associated symptoms remains unclear. We aimed to investigate the prevalence of vitamin D deficiency in knee OA patients and its relationship with inflammatory markers and clinical symptoms. Methods This retrospective study analyzed 986 patients with knee OA over a 3.5-year period. Vitamin D levels, ESR, and platelet counts were assessed, along with demographic and clinical data. Statistical analyses were conducted to explore associations. Result This study involved 986 patients with knee OA, majority of them (85% ) were female with mean age 52.95 ± 12.44 years. More than half of patients 59.7% had unilateral knee OA and 40.3% had bilateral knee OA. The mean value of Vitamin D3 was 25.35 ± 14.125. Vitamin D deficiency was observed in 70.9% of patients, with moderate deficiency being most prevalent (36.94%). No significant association was found between vitamin D levels and inflammatory markers. However, a strong association was observed between vitamin D deficiency and symptoms like polyarthralgia (p < .05)., Bilateral OA was associated with higher vitamin D deficiency levels compared to unilateral OA (P < .001). Conclusion OA more prevalence among female .As well as, vitamin D deficiency is highly prevalent in knee OA patients and its severity associated with Bilateral OA and polyarthralgia but not with inflammatory markers. Future research should focus on the long-term impact of vitamin D supplementation and the molecular mechanisms underlying these disparities. |
