The Therapeutic Effects and Mechanism of PDRN (Polydeoxyribonucleotide) Injections in Musculoskeletal Pain Management

by Son PMR(Physical medicine &Rehabilitation ) & Chiropractic Clinic in Seoul

1. What is PDRN Injection?

PDRN (Polydeoxyribonucleotide) is a substance derived from the DNA of salmon germ cells. It is known for its ability to promote cell regeneration and tissue repair. Traditionally used for skin regeneration, wound healing, and anti-inflammatory purposes, PDRN is now being utilized in the management of musculoskeletal pain.

2. Expected Benefits of PDRN Injections

1) Promoting Tissue Regeneration and Repair

PDRN activates Growth Factors and enhances the proliferation of Fibroblasts, which may positively influence the recovery of damaged muscles, ligaments, and tendons.

2) Potential Anti-Inflammatory Effects for Pain Relief

PDRN may help regulate inflammatory responses, providing anti-inflammatory benefits that could be particularly useful in improving chronic inflammation.

  • Supporting Literature: Lee et al. (2017), "Anti-inflammatory effects of PDRN in tendonitis models," Inflammation Research.

3) Enhancing Blood Flow and Promoting Angiogenesis

PDRN may activate Vascular Endothelial Growth Factor (VEGF), assisting in angiogenesis (formation of new blood vessels), which can contribute to improved blood circulation in affected areas.

  • Supporting Literature: Park et al. (2019), "The role of PDRN in enhancing microcirculation in musculoskeletal disorders," Clinical Rehabilitation.

3. Why Does the Effect of PDRN Injections Take Time?

1) Characteristics of Biological Regeneration Processes

The primary mechanism of PDRN involves cell regeneration and tissue repair, which is aimed at achieving long-term benefits. These natural healing processes require time to complete.

  • Tissue Regeneration Time: New collagen synthesis and cell regeneration may take several weeks.
  • Vascular Regeneration Process: Improvements in blood flow through angiogenesis also occur gradually.

2) Gradual Modulation of Inflammatory Responses

Unlike conventional painkillers that provide immediate relief, PDRN works by reducing inflammation over time, which might delay the onset of noticeable effects, especially in chronic inflammation cases.

3) Individual Variability in Response

  • Age: Older individuals may experience slower cell regeneration.
  • Health Status: Chronic conditions such as diabetes or immune disorders can prolong recovery times.
  • Type of Injury: Chronic pain or degenerative conditions typically respond more slowly compared to acute injuries.

4) Treatment Process Characteristics

  • PDRN injections may not provide immediate effects like traditional painkillers.
  • Generally, more than five sessions may be needed, and the effects are often observed 2-4 weeks after treatment initiation.

4. Application Areas and Procedure of PDRN Injections

Possible Application Areas

  • Management of Degenerative Joint Disorders
  • Support for Ligament and Tendon Recovery
  • Chronic Muscle Pain and Myofascial Pain Syndrome Management
  • Enhancement of Recovery from Sports Injuries and Post-Surgical Rehabilitation

Procedure of PDRN Injection

  • PDRN injections are administered directly into the affected or painful area.
  • Skilled physicians often perform the injection blindly, but ultrasound guidance can be used if necessary.
  • The procedure is relatively quick and generally associated with minimal discomfort and low risk of side effects.

5. Conclusion: Expected Effects of PDRN Injection and the Need for Patience

PDRN injections are considered a safe and effective option for managing musculoskeletal pain by promoting natural tissue regeneration. However, it is important to understand that the effects may take time to manifest, and a long-term perspective is essential when undergoing treatment.

With consistent treatment, patients may experience pain relief and functional recovery. PDRN offers a significant advantage over traditional steroid injections, with fewer side effects, making it a suitable option for long-term management.

 What is Central Sensitization? by Son PMR(Physical medicine & Rehabilitation ) & Chiropractic Clinic in Seoul Central sensitization refers to a condition where the brain and spinal cord become abnormally sensitive to pain signals following an injury or inflammation. In simpler terms, the pathways that perceive pain become overly reactive, causing individuals to experience excessive pain from minor stimuli or persistent pain even after healing . Key Features of Central Sensitization Amplified pain responses (Allodynia) Pain is felt even with non-painful stimuli, such as light touch or gentle movement. Increased pain sensitivity (Hyperalgesia) Painful stimuli feel much more intense than usual. Persistent pain Pain can continue even after the original injury or inflammation has resolved. How Central Sensitization Develops Peripheral nerve injury or inflammation → Continuous transmission of pain signals to the spinal cord and brain → Hyperexcitab...

[Case Study] Improvement of Hyperacusis, Facial and Ear Pain, and Dizziness in a Woman in Her 60s through Upper Cervical, TMJ, and Myofascial Integration Care by Son PMR(Physical medicine & Rehabilitation ) & Chiropractic Clinic in Seoul A woman in her early 60s presented to our clinic with the following symptoms: Hyperacusis (sound sensitivity) Persistent facial pain and inner ear discomfort Dizziness triggered by neck and shoulder muscle tension Tightness and pressure in the temporomandibular (TMJ) region Despite prior evaluation by ENT and neurology specialists, no structural abnormalities were found on imaging studies. Medication had limited effect. Given the complexity of her symptoms, we performed a functional assessment of the upper cervical spine, TMJ region, and cervical myofascial chains, and applied a multi-modal, non-invasive approach. Treatment Overview Upper Cervical Manual Integration (C0–C2) Assessment tools: posture analysis, prone leg check, head rotation test...
