High prevalence of vitamin D deficiency in elderly patients with advanced osteoarthritis scheduled for total knee replacement associated with poorer preoperative functional state

Abstract: Vitamin D deficiency has been reported previously in patients with osteoarthritis undergoing total hip arthroplasty. We found a high prevalence of vitamin D deficiency in elderly patients with advanced knee osteoarthritis scheduled for total knee replacement and also a significant association with a lower preoperative functional state. A review of the literature is given on vitamin D deficiency in patients with knee osteoarthritis and the association with lower outcome scores after arthroplasty is discussed.Vi… Show more

“…Five publications observed no significant difference in the incidence of adverse outcomes between groups with lower and higher vitamin D status [ 11 , 14 , 15 , 17 , 34 ]. However, in none is it clear that no difference truly exists, or if design and conduct constraints preclude detection of a correlation.…”

“…Because TKA results in substantial injury to extensor mechanism of the knee, it is pertinent to evaluate the association between serum vitamin D levels and functional recovery following TKA. In a recent study correlating vitamin D levels with postoperative outcomes in patients undergoing TKA, patients with vitamin D deficiency (defined as serum 25(OH) D < 16 ng/mL) had lower preoperative KSS (31.5 vs. 37.1, p = 0.047) when compared to patients without deficiency [24]. Although the post-operative KSS was also lower in patients with vitamin D deficiency, the difference between the two groups was not statistically significant (74.6 vs. 80.4, n.s.).…”
