Total knee replacement may be more painful for vitamin-D deficient postmenopausal women

(The North American Menopause Society (NAMS)) Vitamin D is a critical part of a healthy diet. Among other benefits, it has been shown to protect against bone disease and maintain soft tissue health. A new study suggests that it may also play a role in the degree of postoperative pain postmenopausal women experience after undergoing total knee replacement. Study results are published online today in Menopause, the journal of The North American Menopause Society (NAMS).
