PY - 2018 TI - High prevalence and seasonal variation of hypovitaminosis D in patients scheduled for lower extremity total joint arthroplasty JF - Annals of Translational Medicine; Vol 6, No 16 (August 30, 2018): Annals of Translational Medicine Y2 - 2018 KW - N2 - Background: High rates of vitamin D insufficiency and deficiency have been demonstrated in various patient populations, including patients undergoing total joint arthroplasties (TJA). However, the risk factors associated with this condition and its seasonal variation is still to be determined in patients scheduled for elective TJA. Methods: We retrospectively identified 226 (116 hips, 120 knees) patients who underwent primary TJA, and had a vitamin D measurement, at a single institution (latitude, 41° 30' N) from 2006 to 2016. Demographics, comorbidities, and perioperative data were collected from electronic medical records. Patients were stratified into vitamin D sufficient (≥30 ng/mL), insufficient ( UR - https://atm.amegroups.org/article/view/20981
