Treatment Options, Selected for You
Explore the tools available within our treatment philosophy — from advanced regenerative procedures to supportive wellness therapies. Every plan is individualized to your evaluation.
PRP Injections (Platelet Rich Plasma)
Concentrated platelets and growth factors from your own blood
PRP therapy utilizes concentrated platelets from your blood, rich in natural growth factors and proteins. Under high-resolution ultrasound or fluoroscopic guidance, PRP is precisely delivered to the affected area to support the body's natural healing response in injured tendons, ligaments, and joints.
- Minimally invasive, uses your own biology
- Image-guided precise delivery
Bone Marrow Concentrate (BMC)
Autologous bone marrow concentrate for complex joint and spine conditions
Bone Marrow Concentrate (BMC) uses a patient's own bone marrow, which contains a population of cells that may support tissue health. Using proprietary Regenexx processing, the concentrate is prepared and delivered via image-guided injection to the precise area of concern. BMC is typically considered for more involved joint or spine conditions.
- Autologous — derived from your own bone marrow
- Image-guided precision placement
Regenexx Procedures
A nationally recognized interventional orthobiologic platform
As a certified Regenexx provider, our practice is part of a national network of physicians specializing in interventional orthobiologics. Regenexx procedures are performed by trained physicians using proprietary protocols and image-guided precision to deliver individualized treatment. Regenexx maintains a clinical outcomes registry tracking patient-reported results.

MLS Laser Therapy
Dual-wavelength therapeutic light therapy
Multiwave Locked System (MLS) laser uses synchronized light wavelengths to penetrate deep into soft tissues, stimulating cellular energy (ATP) and supporting the body's natural recovery processes.

TenJet Tendonitis Treatment
Precision hydro-resection for chronic tendon issues
TenJet utilizes a controlled stream of saline to selectively address diseased tendon tissue while preserving surrounding healthy tendon fibers.

As a certified Regenexx provider, our practice is part of a national network of physicians specializing in interventional orthobiologics. Regenexx procedures are performed by trained physicians using proprietary protocols and image-guided precision to deliver precise, individualized treatment.
Platelet Rich Plasma
Regenexx PRP uses a proprietary processing method to concentrate platelets and their associated growth factors from your own blood. When precisely injected under image guidance into the affected area, PRP is intended to support the body's natural healing response in injured tendons, ligaments, and joints. Regenexx-processed PRP is tailored to the specific condition being treated.
- Autologous — uses your own blood platelets
- Precise image-guided delivery to the injury site
- Proprietary lab processing tailored to your condition
- Performed by a certified Regenexx physician
Bone Marrow Concentrate
Regenexx BMC (Bone Marrow Concentrate) uses a patient's own bone marrow, which contains a population of cells that may support tissue health. Using proprietary Regenexx processing, the concentrate is prepared and delivered via image-guided injection to the precise area of concern. BMC procedures are typically considered for more involved joint or spine conditions.
- Autologous — derived from your own bone marrow
- Image-guided precision placement into the treatment area
- Proprietary Regenexx cell-processing protocol
- Considered for complex joint and spine conditions
MLS Laser Therapy
Multiwave Locked System (MLS) laser uses synchronized light wavelengths to penetrate deep into soft tissues, stimulating cellular energy (ATP) and supporting the body's natural recovery processes. MLS laser therapy may be used as a complementary treatment alongside Regenexx PRP and BMC procedures to support recovery and comfort.
- Non-invasive and pain-free
- May reduce pain and swelling
- Enhances blood circulation
- Complements biologic procedures
Regenexx maintains a clinical outcomes registry, tracking patient-reported results across its national provider network. Individual results vary, and eligibility for any Regenexx procedure is determined through an individualized physician evaluation.
Look Beyond the Pain. Understand the Whole Person.
We look beyond where it hurts to understand the whole picture — how joints, tissues, movement, nerves, and recovery interact — and build an individualized treatment plan around you.
How joints, tissues, movement, nerves, and recovery interact.
We take time to understand the full picture — your history, your movement patterns, your goals — and build an individualized plan that considers how every part of your body works together. Treatment is never one-size-fits-all.

Understanding the whole picture means seeing how every system works together.

What May Be Keeping Pain Active?
Persistent orthopedic pain can involve multiple interconnected factors. These are examples of factors that may contribute to ongoing pain — identifying the relevant drivers requires an individualized evaluation.
Incomplete Healing
Tissue that never fully repaired may continue to generate pain signals long after the original injury.
Instability
When joints lack proper support, surrounding muscles and ligaments may compensate, creating ongoing strain.
Mechanical Overload
Repetitive stress beyond what tissue can tolerate may progressively worsen damage and sustain pain.
Chronic Inflammation
An inflammatory response that doesn't resolve may keep tissues irritated and sensitive over time.
Compensation
The body may alter movement patterns to avoid pain, placing new stress on other structures.
Nerve Irritation
Nerves that remain sensitized or compressed can produce persistent pain even as surrounding tissue heals.
Movement Avoidance
Avoiding movement to reduce pain may lead to stiffness, weakness, and reduced function over time.
Progressive Degeneration
Untreated structural changes may continue to advance, contributing to a cycle of worsening discomfort.

One problem can contribute to another. Incomplete healing may lead to compensation, which may cause mechanical overload, which may sustain inflammation — creating a cycle that keeps pain active. Our evaluation works to identify which factors are relevant to you.

We don't just focus on reducing pain.
We help people work toward returning to the lives pain has taken them away from.
"I want my body back."
"I want my independence back."
"I want to trust my knees again."
"I want to travel again."
"I want to play with my grandchildren."
"I want to stop planning my life around pain."
Treatment is a means to an end. The goal isn't just less pain — it's the life that comes after.
