Abstract：
This study evaluates the effect of vitamin D status in patient outcomes after hip or knee joint surgery.
Literature search was carried out in electronic databases, and study selection followed predetermined eligibility criteria. Data were extracted from relevant studies and meta-analyses of standardized mean differences between hypovitaminosis D (vitamin D deficiency or insufficiency) and euvitaminosis D in assessment scores of patient-reported outcomes were performed.
A total of 12 studies (2,593 patients; age 69.89 years [95% CI 68.07-71.70]; 35.95% [29.43-42.46] males) were included in the meta-analysis. The prevalence of hypovitaminosis D (vitamin D deficiency or insufficiency) was 33.18% [25.10-41.26], but the combined prevalence of deficiency and insufficiency was 46.99 [34.02-59.96]. Hospital stay was 1.09 days [-0.39 to 2.56] longer in the hypovitaminosis D group compared to the euvitaminosis D group. Preoperatively, Harris Hip Score (HHS) and Knee Society Score were significantly lower (p = 0.001 and p = 0.00001, respectively) in the hypovitaminosis D group than in the euvitaminosis D group. Postoperatively, HHS (p = 0.004) score was significantly lower in the hypovitaminosis D group than in the euvitaminosis D group.
The prevalence of hypovitaminosis D is high in osteoarthritis patients undergoing knee or hip surgery. Vitamin D deficiency may affect the outcomes of orthopedic joint surgery. However, randomized trial/s will be required to confirm these findings.
