The Role of Vitamin D Supplementation in Enhancing Muscle Strength Post-Surgery: A Systemic Review

Area of Science:

• Orthopaedic Surgery
• Nutritional Science
• Rehabilitation Medicine

Background:

• Vitamin D is crucial for musculoskeletal health and muscle function.
• Preoperative and postoperative benefits for bone health are known, but effects on muscle recovery are less understood.
• This review focuses on vitamin D's impact on post-surgical muscle strength.

Purpose of the Study:

• To systematically review evidence on vitamin D supplementation for post-surgical muscle strength.
• To consolidate findings on vitamin D's role in surgical recovery.

Main Methods:

• Systematic literature search adhering to PRISMA guidelines.
• Inclusion of studies on vitamin D supplementation and muscle strength post-surgery.
• Narrative synthesis of data due to study heterogeneity.

Main Results:

• Ten studies indicated vitamin D supplementation, particularly high-dose preoperative/early postoperative, improves muscle strength and function.
• Benefits observed in orthopaedic (hip/knee replacement) and bariatric surgeries.
• Variability in benefits noted based on surgery type, baseline vitamin D, and supplementation strategy.

Conclusions:

• Vitamin D supplementation holds potential for enhancing post-surgical muscle recovery and functional outcomes.
• Tailored supplementation strategies are crucial for optimal patient outcomes.
• Further research is required on optimal dosing and long-term effects.
