This is the clinical evidence summary written for health professionals. It is technical, and it lists the research this page was built from. You do not need to read it to understand your treatment or to make a decision about it.

Overview

• More research is needed to determine the effect of vitamin D supplementation on bone health and injury risk in elite athletes [1].
• A diagnosis of vitamin D deficiency is associated with increased rates of anterior cruciate ligament tears and reconstruction failure [2].
• Vitamin D status should be assessed in high-risk populations to guide preventive strategies focused on maintaining optimal levels regarding stress fracture risk [3].
• Educational initiatives and revised guidelines may have improved vitamin D prescription rates after fragility fracture, but there is a need to raise awareness about the importance of vitamin D for bone health, particularly in older adults [4].
• Vitamin D represents a potentially modifiable risk factor that could be optimized during both surgical and nonsurgical management of patients with Charcot arthropathy [5].
• Regular vitamin D supplementation significantly reduces the likelihood of deficiency among arthroplasty patients presenting in winter [6].
• Determining vitamin D levels preoperatively and providing supplementation if deficiency is present may be beneficial for preventing delayed wound healing after open carpal tunnel release surgery [7].
• Evidence suggests vitamin D may support tendon healing, particularly in rotator cuff repair, although studies remain low quality and limited to a single tendon group [8].
• Targeted interventions are needed to optimize musculoskeletal and metabolic health in adolescents with vitamin D deficiency and adverse body composition [9].
• Preoperative vitamin D screening and potential supplementation strategies are important for patients who have vitamin D levels below 20 ng/mL undergoing hip fracture surgery under general anesthesia [10].
• Nonselective preoperative vitamin D supplementation appears to be more cost-effective than selective supplementation in arthroscopic rotator cuff repair, likely due to the lower cost of 25(OH)D supplementation compared to serum assays [11].
• Administering an oral 300,000 U single-dose vitamin D regimen to correct vitamin D deficiency can positively impact outcomes following primary total joint arthroplasty [12].
• Peptide supplements should not currently be recommended as a replacement or adjunct for existing orthopaedic standard of care due to the lack of robust efficacy and safety data [13].
• Orthopedic surgeons should recognize vitamin D deficiency as a potential modifiable risk factor for postoperative complications in total shoulder arthroplasty [14].
• Findings from a systematic review and meta-analysis do not justify routine testing and supplementation of vitamin D in patients undergoing rotator cuff repair [19].
• Hand grip strength, vitamin D status, and diets might be considered diagnostic non-invasive predictors of bone health for clinical use in epidemiological contexts in 6–12 years old school children [21].
• Current evidence is inconsistent and insufficient to support universal vitamin D supplementation for total knee arthroplasty outcomes [22].
• Recommendations for data capture relating to female athlete population characteristics, and injuries, illnesses and other health consequences, will improve the quality of epidemiological studies to inform better injury and illness prevention strategies [28].

How It Works

Bone Health and Fracture Risk

• Vitamin D status should be assessed in high-risk populations to guide preventive strategies focused on maintaining optimal levels [3].
• Preoperative vitamin D screening and potential supplementation strategies are important for patients who have vitamin D levels below 20 ng/mL [10].
• Maintaining adequate vitamin D levels may improve longer term survival after proximal femoral fracture surgery, although vitamin D status alone may not influence immediate recovery [18].
• Active vitamin D3 treatment promoted fracture healing by affecting the levels of immune factors in osteoporotic fracture patients [23].
• Sixteen weeks of high-intensity interval training and vitamin D consumption showed greater benefits for bone mineral density levels in women with osteoporosis than either vitamin D consumption or high-intensity interval training alone [17].
• Regular vitamin D supplementation significantly reduces the likelihood of deficiency [6].
• Low-dose vitamin D supplementation was beneficial for vitamin D–sufficient total knee arthroplasty patients to achieve higher levels and maintain sufficiency [20].
• Deficient patients benefitted from medium-to-high dose vitamin D supplementation after total knee arthroplasty, though only 33.7% achieved repletion [20].
• Hand grip strength, vitamin D status, and diets might be considered diagnostic non-invasive predictors of bone health for clinical use in epidemiological contexts [21].

Soft Tissue Healing and Musculoskeletal Integrity

• Evidence suggests vitamin D may support tendon healing, particularly in rotator cuff repair, though studies remain low quality and limited to a single tendon group [8].
• Combining systemic and localized vitamin D delivery significantly enhanced tendon-to-bone healing, muscle regeneration, and biomechanical strength in a rabbit rotator cuff tear model compared to other treatment groups [24].
• Lower preoperative serum vitamin D levels had a strong correlation with lower tissue vitamin D levels and lower serum vitamin D levels at 1 year after rotator cuff repair surgery [27].
• Vitamin D deficiency was associated with increased proinflammatory cytokine expression in the deltoid muscle of patients with rotator cuff tears, unlike in the supraspinatus muscle [30].
• Vitamin D deficiency was not associated with the expression of myogenesis-related or muscle atrophy–related genes in the supraspinatus muscle of patients with rotator cuff tears [30].
• Preoperative serum vitamin D deficiency is associated with increased rotator cuff fatty degeneration but is unlikely to influence post repair outcomes [19].

Inflammation and Immune Modulation

• Supplementation with vitamin D 10,000 IU/day for 8 weeks can increase vitamin D levels >50 ng/dl to optimally act as an immunomodulator in tuberculosis spondylitis patients [16].
• Vitamin D deficiency is highly prevalent in knee osteoarthritis patients and its severity is associated with bilateral osteoarthritis and polyarthralgia but not with inflammatory markers [15].

Clinical Management and Outcomes

• Further research is necessary to elucidate the direct role of vitamin D in the pathogenesis of rotator cuff tears and its impact on clinical outcomes after rotator cuff surgery and total shoulder arthroplasty [25].
• Future research should determine whether correcting hypovitaminosis D improves outcomes after anterior cruciate ligament injury [31].

What the Evidence Shows

Injury Risk and Prevalence

• Vitamin D deficiency is highly prevalent in knee osteoarthritis patients [15].
• The severity of vitamin D deficiency in knee osteoarthritis patients is associated with bilateral osteoarthritis and polyarthralgia [15].
• The severity of vitamin D deficiency in knee osteoarthritis patients is not associated with inflammatory markers [15].
• Higher prevalence of vitamin D deficiency is observed among arthroplasty patients presenting in winter [6].
• Lower preoperative serum vitamin D levels have a strong correlation with lower tissue vitamin D levels and lower serum vitamin D levels at 1 year after rotator cuff repair surgery [27].

Fracture and Bone Health Outcomes

• Preoperative vitamin D screening and potential supplementation strategies are important for patients who have vitamin D levels below 20 ng/mL undergoing hip fracture surgery [10].
• Combined calcium and vitamin D supplementation may improve pelvic bone mineral density and correct serum 25OHD deficiencies in postmenopausal women with osteoporosis [32].
• Combined calcium and vitamin D supplementation does not reduce clinical fracture risk in postmenopausal women with osteoporosis [32].
• Regular sling core stabilization training based on calcium and vitamin D supplementation can improve bone mineral density and prevent low back pain in a patient with primary osteoporosis over a 6-year period [34].

Surgical Outcomes and Complications

• Preoperative vitamin D deficiency is associated with increased rotator cuff fatty degeneration but is unlikely to influence post-repair outcomes [19].
• The findings regarding rotator cuff repair do not justify routine testing and supplementation of vitamin D in patients undergoing rotator cuff repair [19].
• Vitamin D deficiency is associated with adverse medical outcomes following total shoulder arthroplasty [14].
• Supplementation with 50,000 international units vitamin D3 on the day of surgery failed to demonstrate statistically significant differences in functional Knee Society Score, Timed Up and Go Test times, or complications in the early postoperative period compared to placebo for total knee arthroplasty [33].
• Deficient total knee arthroplasty patients benefited from medium-to-high dose vitamin D supplementation, though only 33.7% achieved repletion [20].

Supplementation Strategies and Cost-Effectiveness

• Nonselective vitamin D supplementation appears to be more cost-effective than selective supplementation for arthroscopic rotator cuff repair, likely due to the lower cost of 25(OH)D supplementation compared to serum assays [11].

Tissue Healing and Preclinical Models

Other Clinical Associations

Practical Considerations

Screening and Assessment

• Preoperative vitamin D screening is important for patients who have vitamin D levels below 20 ng/mL [10].
• Determining vitamin D levels preoperatively may be beneficial for preventing delayed wound healing after open carpal tunnel release surgery [7].
• Vitamin D deficiency is associated with increased short- and long-term mortality in patients receiving hip fracture surgery under general anesthesia [10].
• Vitamin D deficiency is a potentially modifiable risk factor that could be optimized during both surgical and nonsurgical management of patients with Charcot arthropathy [5].

Supplementation Strategies

• Providing supplementation if vitamin D deficiency is present preoperatively may be beneficial for preventing delayed wound healing [7].
• Deficient total knee arthroplasty patients benefitted from medium-to-high dose vitamin D supplementation, though only 33.7% achieved repletion [20].
• Nonselective vitamin D supplementation appears to be more cost-effective than selective supplementation in arthroscopic rotator cuff repair [11].
• The lower cost of 25(OH)D supplementation compared to serum assays likely contributes to the cost-effectiveness of nonselective supplementation in arthroscopic rotator cuff repair [11].

Outcomes and Prognosis

• Maintaining adequate vitamin D levels may improve longer term survival after proximal femoral fracture surgery [18].
• Vitamin D status alone may not influence immediate recovery after proximal femoral fracture surgery [18].
• Among Americans over the age of 40, the increase in serum HDL-C is related to decreased bone mineral density of the spine only in women aged 40–59 years with vitamin D insufficiency or deficiency [29].
