Introduction: Fluorosis has been associated with an
increased risk of degenerative changes in the knee. Multiple
studies have found an association between arthritis and
elevated fluoride levels. We aim to delineate if elevated
fluoride level has any direct correlation with the degree of
radiological grading and clinical symptoms in knee arthritis.
Materials and Methods: A cross-sectional study of 80 knee
arthritis patients was conducted from February 2017 to April
2018. Serum fluoride levels were measured and patient’s
pain scores, WOMAC scores and radiological grading were
correlated with the elevated fluoride levels.
Results: In our study, 30 out of 80 patients had increased
serum fluoride level. Statistically significant differences
were noted in VAS score, WOMAC score and Kellgren and
Lawrence radiological grades between patients with normal
serum fluoride level and those with elevated fluoride level.
Conclusion: There is an increased risk of knee arthritis in
patients with elevated blood fluoride levels and patients with
increased fluoride levels are associated with more severe
symptoms and radiographic disease.
