Why I Combine Photobiomodulation with Regenerative Orthobiologics

Preparing the Biology of Healing Before and After Every Joint Procedure

One of the biggest misconceptions in regenerative medicine is that healing begins when the injection is performed. In reality, the injection is only one part of the regenerative process. The outcome depends largely on the biological environment into which those regenerative products are placed.

That philosophy is the foundation of the RegeneZone Method™. Rather than viewing regenerative orthobiologic procedures as a single event, I view them as a comprehensive process of preparing the body before treatment and supporting tissue repair long afterward. One of the most valuable tools I use throughout that journey is photobiomodulation (PBM).

Photobiomodulation uses specific wavelengths of red and near-infrared light to stimulate cellular metabolism without generating heat or damaging tissue. The recently published 2025 World Association for Laser Therapy (WALT) Position Paper reviewed more than 200 studies evaluating PBM in regenerative medicine and concluded that it consistently improves cell viability, proliferation, differentiation, angiogenesis, tissue regeneration, wound healing, and cellular communication. Remarkably, only 11 of the 204 studies reviewed failed to demonstrate a measurable benefit.

For me, these findings reinforce something I have believed for years: regenerative procedures work best when we first optimize the biology of healing.

Why Photobiomodulation Works

Every tissue in the body depends on energy to heal. Cells require healthy mitochondria, adequate oxygen delivery, proper circulation, controlled inflammation, and an intact extracellular matrix to repair damaged tissue effectively.

Photobiomodulation improves nearly every one of these variables.

According to the WALT review, PBM has been shown to:

  • Increase mitochondrial ATP production

  • Improve cellular metabolism

  • Enhance cell survival

  • Stimulate cellular proliferation

  • Increase migration into injured tissue

  • Promote angiogenesis

  • Reduce inflammatory cytokines

  • Increase secretion of regenerative signaling molecules

  • Accelerate tissue healing after regenerative procedures

The paper also demonstrated that PBM follows a biphasic dose response. More energy is not necessarily better. Most successful studies used relatively low therapeutic doses, particularly when the goal was enhancing cellular proliferation, highlighting the importance of using the correct wavelengths and treatment parameters rather than simply increasing power.

The Research Protocols

Although no single standardized protocol exists, the WALT review identified several consistent patterns across more than 200 studies.

The strongest evidence supports the use of:

Red Light

  • 630–660 nm

Primarily for:

  • superficial tissues

  • collagen production

  • wound healing

  • fibroblast activity

  • cellular proliferation

Near Infrared Light

  • 800–890 nm

Primarily for:

  • deeper joints

  • muscles

  • tendons

  • ligaments

  • cartilage

  • bone

  • peripheral nerves

Most successful studies delivered relatively low energy densities—generally between 0.5 and 5 J/cm², with 0.5–2 J/cm² commonly used when the goal was enhancing cellular proliferation. Importantly, repeated treatments consistently outperformed single treatments. Many investigators treated tissues daily or several times per week over a period of two to six weeks rather than relying on a single application.

To me, this is one of the most clinically important findings in the paper. Regeneration is not an event—it is a process.

My Clinical Protocol

This research closely mirrors how I have incorporated photobiomodulation into the RegeneZone Method™.

Rather than performing a single laser treatment in the office, I have patients use a cutting-edge handheld home photobiomodulation laser every day as part of their regenerative program.

For most joint procedures using HCT/P orthobiologic products, my protocol is straightforward:

Phase One: Biological Priming

Patients begin daily photobiomodulation four weeks before their procedure.

The objective is to:

  • reduce chronic inflammation

  • improve regional circulation

  • increase mitochondrial ATP production

  • optimize cellular metabolism

  • prepare the local tissue environment for regeneration

By improving the biology before the procedure, we are creating a healthier foundation for the regenerative products to perform their job.

Phase Two: Regenerative Procedure

Once the tissue has been biologically optimized, I perform an ultrasound-guided injection using the appropriate HCT/P regenerative product based on the patient's condition and treatment plan.

Phase Three: Recovery and Remodeling

Healing does not stop after the procedure.

Following the injection, patients continue using their handheld home photobiomodulation laser every day for another four weeks.

During this recovery phase, I also incorporate focused acoustic wave therapy, which I begin after the procedure as part of the remodeling process. Acoustic wave therapy improves local blood flow, stimulates angiogenesis, enhances mechanotransduction, and helps organize collagen during tissue repair. When combined with daily photobiomodulation, these therapies create an environment that supports continued healing throughout the critical remodeling phase.

The goal is not simply to perform an injection. The goal is to actively support regeneration every day during the weeks when healing is occurring.

Why This Matters

One of the most exciting findings from the WALT review is that photobiomodulation appears to enhance the release of extracellular vesicles and other regenerative signaling molecules. One study demonstrated more than a six-fold increase in extracellular vesicle secretion following photobiomodulation, suggesting that PBM may significantly amplify the communication pathways responsible for tissue repair.

The review also demonstrated improvements in:

  • angiogenesis

  • collagen remodeling

  • bone regeneration

  • tendon healing

  • muscle repair

  • nerve recovery

  • wound healing

  • modulation of inflammation

These findings reinforce my belief that regenerative medicine should focus as much on optimizing the tissue environment as on the biologic product itself.

My Philosophy

For years, I have said that regenerative procedures are only as successful as the biology receiving them.

That is why I spend so much time preparing the tissue before treatment and supporting healing afterward. Daily home photobiomodulation before and after the procedure, combined with focused acoustic wave therapy during recovery, allows regeneration to continue long after patients leave my office.

The procedure may take less than an hour.

Healing takes weeks.

My goal is to support that healing every single day.

That is the philosophy behind the RegeneZone Method™: optimize the biology first, support the regeneration continuously, and allow the body to do what it was designed to do—heal.
