Background:
Vitamin D deficiency is a global problem, and 13 to 75% of patients undergoing total joint arthroplasty (TJA) have vitamin D deficiency. Several studies have shown that low preoperative vitamin D levels may increase the risk of postoperative complications, including periprosthetic joint infection (PJI), in patients undergoing primary TJA. Most of the studies are underpowered. This study aimed to investigate the relationship between vitamin D deficiency and surgical and medical complications after primary TJA, with a specific focus on PJI.
Methods:
Prospectively collected institutional multicenter arthroplasty databases were reviewed to identify patients who underwent primary total knee and hip arthroplasty. The study group was defined as patients whose vitamin D level is < 30 ng/dL and who received a single oral dose of 7.5 mg (300,000 IU) D3 within two weeks before index surgery (n = 488; mean age 63 years). Patients in the control group were those whose preoperative vitamin D levels were unknown and who did not receive vitamin D supplementation (n = 592, mean age 66). The groups were compared regarding 90-day medical and surgical complications, including PJI, mortality, and readmission rates.
Results:
The total number of complications (8.6 and 4.3%; respectively; P = .005), superficial wound infection (2.5 and 0.2%, respectively; P < .001), and postoperative cellulitis (2.2 and 0% respectively; P < .001) were statistically significantly higher in the patient group who did not receive vitamin D supplementation. However, 90-day mortality (P = .524), PJI (P = .23), and readmission rate (P = .683) were similar between the groups.
Conclusions:
This study demonstrated that preoperative optimization of vitamin D levels may be beneficial in reducing postoperative complications, including superficial wound infection and postoperative cellulitis. Administering an oral 300,000 U single-dose vitamin D regimen to correct vitamin D deficiency can positively impact outcomes following primary TJA.

Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...
01:29Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
