Abstract

Aim: To assess the serum Vitamin D levels and Kellgren-Lawrence grading in patients of
Primary Osteoarthritis.
Materials and Methods: The present observational study was carried out on the patients
coming to the OPD of the Department of Orthopedics, SMS Medical College and Hospital,
Jaipur. All patients complaining of Osteoarthritis of the knee joint and willing to participate
in the study were interviewed for age, sex, history of inflammatory arthritis or any rheumatic
disease, complain of celiac disease & malabsorption syndrome or any history of intake of any
drug that might affect serum Vit D levels. After the successful running of Quality Controls
the clear serum obtained from patient’s serum was analyzed on Advia Centaur XP (for
Vitamin D & PTH) & fully automated chemistry analyzer Beckman Coulter AU 680 (for
routine biochemical parameters). Based on the serum biochemistry results, patients with
deranged RFT & LFT were excluded from the study & the Serum Vitamin D, PTH, Calcium
and Phosphorus levels of the patients with normal RFT & LFT were documented.
Results: In our study maximum number of patients (109, 41.44%) fell in the age group 51-60
years with age ranging from 37-70 years. Mean age is 55.37 ± 8.04 years. Male female ratio
was 0.81:1. Mean serum Vitamin D level is 18.27±8.34 ng/ml with range from 4.2-44.34
ng/ml. Maximum no. of patients were in the Vitamin D deficient group (148, 56.27%), 96
(36.5%) patients were Vitamin D insufficient while only 19 (7.23%) patients had Vitamin D
levels above normal range. Maximum number of cases were of grade 3 (90, 34.22%).
followed by grade 2 (82, 31.18%). Minimum no. of cases are of grade 0 (7, 2.66%) followed
by grade 1 (22, 8.36%). The mean Kellgren- Lawrence grading for the cases is 2.68 ± 1.01.
Conclusion: There is high prevalence of Vitamin D deficiency in Osteoarthritis patients. But
this prevalence needs to be compared with the prevalence in general population by including
age & sex-matched healthy controls. The present study could be further taken in this
direction.
