Regenerative Injection Therapies
Your body has the ability to heal. My goal is to activate it.
Whether you're a competitive athlete, an active adult dealing with a stubborn injury, or someone navigating the musculoskeletal changes that come with hormonal shifts — regenerative injections offer a precision-guided path to healing that doesn't rely on cortisone, anti-inflammatories, or surgery.
This care is designed for:
Active adults and athletes
living with tendon pain, ligament instability, or joint degeneration that isn't resolving with rest, PT, or standard car
Professional and competitive athletes
who need faster, smarter recovery without masking the problem
Perimenopausal and menopausal women
experiencing joint pain, frozen shoulder, or musculoskeletal changes that feel out of proportion to their injury history — because estrogen decline directly affects connective tissue integrity and healing capacity
Men navigating andropause
whose joints and tendons are losing resilience as testosterone and growth factors decline
Post-surgical patients
looking to optimize recovery and restore tissue strength
Why Regenerative?
Conventional treatments for joint and soft tissue pain — cortisone injections, NSAIDs, immobilization — are primarily anti-inflammatory. They reduce pain in the short term, but they don't rebuild what's been damaged. In some cases, repeated cortisone injections can actually accelerate tissue breakdown over time.
Regenerative injection therapies work differently. Rather than suppressing the body's response, they harness and amplify it — delivering targeted signals to the tissue that initiate real healing at the cellular level.
The result: stronger tendons and ligaments, improved joint stability, reduced pain, and restored function. Not just symptom management.
In comparison to many practices, most injections at this practice are performed using real-time ultrasound guidance — ensuring precise delivery to the exact tissue that needs treatment.
“Many patients come to me having been told there are no options between physical therapy and surgery. Regenerative injections offer something different: a strategy to rebuild tissue, restore function, and get back to the life you love.”
Types of Injections Offered

The foundation of regenerative care — stimulating your body's own healing cascade.
Prolotherapy is the foundational regenerative injection technique, with a track record spanning more than 70 years of clinical use. It works by introducing a mild irritant, most commonly a dextrose (sugar) solution, into damaged or unstable connective tissue. This controlled stimulus triggers a localized healing response: increased circulation, collagen synthesis, and tissue remodeling.
The result is stronger, more resilient tendons, ligaments, and joint structures.
Prolotherapy is offered in three distinct forms in my practice, each suited to different conditions and treatment goals:
Low-Dose Dextrose Trigger Point Injections
Best for: Muscle pain, myofascial trigger points, referred pain patterns, tension-related headaches, jaw pain (TMJ), and localized soft tissue discomfort.
A dilute dextrose solution is injected directly into active trigger points — hyperirritable knots in muscle tissue that cause localized and referred pain. Unlike traditional trigger point injections with anesthetic alone, dextrose-based trigger point injections offer an anti-inflammatory and restructuring effect, addressing underlying tissue dysfunction rather than temporarily numbing the area.
These injections are often used as part of a broader treatment protocol alongside traditional prolotherapy or PRP.
Traditional Prolotherapy
Best for: Ligament laxity and instability, tendinopathy, chronic joint pain, hypermobility, knee, hip, shoulder, ankle, and foot conditions.
A higher-concentration dextrose solution is injected at ligament and tendon insertion points where tissue meets bone. This stimulates a focused healing response in the exact location where degeneration or laxity has occurred.
Traditional prolotherapy is particularly effective for patients whose pain stems from structural looseness or instability: joints that "give way," tendons that are chronically stiff and sore, or ligaments that were sprained and never fully recovered.
A note on hormones and healing: Estrogen, testosterone, and growth hormone all play a role in connective tissue maintenance. In patients experiencing perimenopause, menopause, or andropause, hormonal decline can impair tissue healing independent of injury. Prolotherapy can be especially valuable for this population — and may be most effective when combined with a comprehensive hormone optimization strategy.
Nerve Hydrodissection
Best for: Peripheral nerve entrapment, nerve-related pain, numbness or tingling, carpal tunnel syndrome, tarsal tunnel syndrome, thoracic outlet syndrome, post-surgical adhesions affecting nerves, and nerve pain associated with hypermobility.
Nerve hydrodissection is a specialized technique in which a fluid solution is precisely injected around a compressed or entrapped peripheral nerve, using real-time ultrasound guidance. The fluid gently separates the nerve from surrounding scar tissue, fascia, or tight structures that are constricting it, releasing the compression and restoring normal nerve mobility.
This is a precise, minimally invasive approach to nerve pain that addresses the mechanical cause of compression, not just the symptoms.
Conditions commonly treated with nerve hydrodissection:
Carpal tunnel syndrome
Cubital tunnel syndrome (ulnar nerve)
Common peroneal nerve entrapment
Post-surgical nerve adhesions

Your body's own healing proteins, concentrated and precisely delivered.
Platelet-Rich Plasma (PRP) takes regenerative treatment a significant step further. A small amount of blood is drawn and processed in a centrifuge to concentrate the platelets, the cells in your blood that carry growth factors and signaling proteins responsible for tissue repair. This concentrated plasma is then injected directly into the damaged tissue under ultrasound guidance.
When platelets arrive at an injury site, they release a cascade of growth factors: PDGF, TGF-β, VEGF, EGF, and others. Each of these plays a specific role in stimulating cell proliferation, new blood vessel formation, collagen synthesis, and inflammation modulation.
Why high-platelet concentration matters: Not all PRP is the same. Platelet concentration varies significantly depending on the preparation system and technique used. I utilize a preparation protocol optimized for high platelet yield, because the evidence consistently shows that higher platelet concentrations produce better clinical outcomes — especially for tendinopathy and osteoarthritis.
Best for:
Moderate to advanced osteoarthritis (knee, hip, shoulder, ankle)
Chronic tendinopathy (rotator cuff, Achilles, patellar, lateral epicondyle)
Partial tendon and ligament tears
Joint conditions where traditional prolotherapy alone may not be sufficient
Patients who have not responded adequately to corticosteroid injections
What to expect: A mild increase in symptoms in the 48–72 hours following treatment is normal and expected — this is the healing response being activated. Patients typically begin to notice improvement over 4–8 weeks, with ongoing tissue remodeling continuing for up to 18 months.

The next evolution in regenerative biologics: targeted, potent, and built for longevity.
Protein Concentrate represents a significant evolution beyond standard PRP. While PRP concentrates all platelets from your blood (including both beneficial and potentially pro-inflammatory components), Protein Concentrate isolates specific high-value bioactive proteins that play a direct role in tissue repair and in protecting joint structures from further degeneration.
The key proteins in a therapeutic Protein Concentrate preparation include:
Alpha-2-Macroglobulin (A2M): A large plasma protein with powerful protease-inhibiting properties. A2M binds and neutralizes the destructive enzymes (particularly the aggrecanases and MMPs) responsible for cartilage breakdown in osteoarthritis — essentially acting as a biological "shield" for joint cartilage.
Interleukin-1 Receptor Antagonist Protein (IL-1ra): A naturally occurring anti-inflammatory protein that blocks the activity of IL-1β, one of the primary drivers of inflammatory joint destruction.
Fibronectin and other extracellular matrix proteins: Supporting cell adhesion, tissue organization, and structural repair.
Protein Concentrate vs. A2M Injections: What's the Difference?
Patients researching regenerative options will often encounter both "A2M injections" and "Protein Concentrate" as distinct offerings. Here's how they relate:
A2M injections refer specifically to preparations that isolate and concentrate Alpha-2-Macroglobulin as the primary therapeutic agent. Some practices offer A2M as a standalone product, often manufactured through a separate processing protocol or sourced as a point-of-care preparation.
Protein Concentrate prepared at this practice concentrates A2M alongside the full spectrum of bioactive plasma proteins — including IL-1ra, fibronectin, and other growth factors — creating a more comprehensive biological treatment. Think of it as a broader-spectrum regenerative biologic that includes A2M as one of several active components.
PC is best for:
Moderate to advanced osteoarthritis, particularly when cartilage preservation is a priority
Patients with significant inflammatory joint disease
Complex cases where PRP alone may not address the full spectrum of joint degeneration
Patients seeking to reduce the frequency and total number of treatments
Athletes or active patients who need durable, long-lasting outcomes
PC can be combined with PRP for a synergistic approach: PRP drives active tissue regeneration while Protein Concentrate provides the anti-catabolic and anti-inflammatory protection needed to preserve the repair.
Precision-Guided. Individualized. Integrated.
What sets this regenerative injection practice apart isn't just the therapies — it's how they're applied.
Ultrasound-Guided Precision Nearly every injection is performed under real-time musculoskeletal ultrasound guidance. This is not the standard in many regenerative practices. Ultrasound imaging allows visualization of the exact tissue structure being treated — whether a tendon, ligament, nerve, or joint — ensuring that the therapeutic agent is delivered to precisely the right location. Accuracy of delivery directly affects clinical outcomes.
Metabolic and Hormone-Informed Treatment Planning: This practice takes a whole-body view. For appropriate patients, regenerative injection therapy is integrated with metabolic and hormone evaluation and optimization, addressing the biological environment that determines whether healing can actually occur. Connective tissue health is inseparable from metabolic and hormonal health. Estrogen protects tendon and ligament integrity. Testosterone supports muscle and tendon strength. Growth hormone drives tissue repair. When these hormones decline, whether through perimenopause, menopause, andropause, or stress, healing is impaired at the cellular level.
A Root-Cause Approach Beyond the injection itself, treatment planning includes evaluation of biomechanical contributors, nutritional factors, metabolic health, and systemic inflammation. Because the best injection in the world won't hold if the underlying conditions driving tissue breakdown aren't addressed.

Follow-Up and Optimization
Healing is a process, not an event. We'll track your progress, assess tissue response, and adjust your protocol as needed.
Frequently Asked Questions
-
This depends entirely on the condition being treated, its severity, and the modality used. Prolotherapy is often delivered in a series of 3-6 treatments, while many patients see meaningful improvement with PRP after 1 treatment. Others with more advanced degeneration may require additional injections or a longer series. This will be discussed clearly during your consultation.
-
Dr. Krake is currently in network with PacificSource and Regence Blue Cross Blue Shield for office visits and consultations through FoRM Health. Regenerative injection therapies (prolotherapy, PRP, and protein concentrate) are typically not covered by insurance, as they are classified as elective procedures by most payers. Pricing and payment options will be discussed at your consultation.
-
Cortisone (corticosteroid) injections reduce inflammation and pain, but they do not stimulate tissue repair. Repeated use of cortisone injections can accelerate cartilage and tendon breakdown. Regenerative therapies aim to initiate actual healing, not suppress the body's response to injury.
-
In most cases, yes, though a waiting period between cortisone and regenerative treatment is recommended. This will be evaluated during your consultation.
-
Commonly treated conditions include: osteoarthritis (knee, hip, foot and ankle, shoulder, hand and wrist), rotator cuff pathology, Achilles tendinopathy, plantar fasciitis, patellar tendinopathy, lateral and medial epicondylitis (tennis/golfer's elbow), sacroiliac joint dysfunction, ligament sprains and laxity, hypermobility-related pain, nerve entrapments, and post-surgical recovery.
-
Discomfort varies by injection type and location. Local anesthetic is used where appropriate to minimize procedural discomfort. Post-treatment soreness, particularly with PRP and prolotherapy, is expected and is a sign that the healing response has been activated. Most patients tolerate injections quite well.
