Understanding the Challenge of Chronic Tendinopathy

As a clinician with decades of experience, I’ve seen countless patients struggle with tendinopathy, a condition often mislabeled as “tendinitis”. The key difference is that tendinitis implies active inflammation, whereas tendinopathy describes a degenerative state of the tendon. In tendinopathy, the tendon’s collagen fibers become disorganized, weakened, and filled with abnormal, painful tissue and sometimes microcalcifications. This is not an inflammatory problem but a structural failure of the tissue.

Conditions like lateral epicondylosis (tennis elbow), patellar tendinopathy (jumper’s knee), Achilles tendinopathy, and plantar fasciitis can be notoriously difficult to treat. Traditional conservative measures like rest, ice, and physical therapy are often effective for acute injuries but may fall short once the condition becomes chronic. In these cases, the degenerative tissue itself prevents healing, creating a cycle of pain and dysfunction. This is where modern, targeted interventions become essential.

Introducing Percutaneous Tenotomy: A Minimally Invasive Revolution

One of the most exciting advancements in musculoskeletal medicine is percutaneous tenotomy, an FDA-approved, ultrasound-guided procedure designed to debride, or remove, diseased tendon tissue. The term “percutaneous” simply means “through the skin,” highlighting its minimally invasive nature. This procedure represents a significant leap forward, offering a more definitive solution than conservative care but far less invasive than traditional open surgery.

The beauty of percutaneous tenotomy lies in its precision. Using real-time ultrasound imaging, we can guide a specialized instrument directly to the damaged tissue. This lets us selectively remove the degenerative, pain-generating portions of the tendon while leaving the surrounding healthy tissue intact. This precision is critical for promoting a robust healing response.

Two primary technologies dominate this field: Tenex and TenJet. Both are now accessible to appropriately trained primary care and specialty providers, allowing these procedures to be performed safely and effectively in the office.

The Tenex Health TX System: Ultrasonic Debridement

At our clinic, we utilize the Tenex Health TX system. This technology is a marvel of bioengineering, leveraging the principles of phacoemulsification—a technique famously used in modern cataract surgery.

• How It Works: The Tenex system uses a handheld device connected to a console. The key component is an 18-gauge, double-lumen needle. When activated by a foot pedal, the needle tip vibrates at an ultrasonic frequency (around 20,000 Hz). This ultrasonic energy precisely emulsifies, or liquefies, the targeted degenerative tendon tissue.
• The Double-Lumen Design: The Tenex probe’s ingenuity lies in its dual functionality. While the vibrating tip breaks down the pathologic tissue, a second, parallel lumen within the same needle simultaneously irrigates the area with saline and suctions the emulsified debris away. This “cut and remove” action is performed in a single, efficient step.
• The Procedure: The procedure is performed under sterile conditions. After administering a local anesthetic, I use an ultrasound probe (covered in a sterile sheath) to visualize the damaged tendon. I insert the Tenex needle through the skin and guide it in real time to the area of tendinopathy. I then activate the device and methodically move the needle tip back and forth through the diseased tissue. The entire debridement process, or “cutting time,” is remarkably short, typically lasting between 30 and 90 seconds. The patient hears a humming sound but feels no pain due to the local anesthetic.

The TenJet System: A High-Velocity Saline Jet

The primary alternative to Tenex is the TenJet system. While the goal is the same—to remove diseased tendon tissue—the mechanism is different.

• How It Works: TenJet uses a technology called hydroresection. Instead of ultrasonic energy, it employs a highly pressurized, high-velocity jet of sterile saline that shoots out from the tip of its specialized needle. This powerful fluid stream acts like a water knife, cutting and excising soft, degenerative tissue.
• Simultaneous Aspiration: Like Tenex, the TenJet wand has a built-in suction feature that immediately removes resected tissue and excess saline, keeping the operative field clear and preventing pressure buildup.
• Comparison: Both Tenex and TenJet are excellent tools. The choice between them often comes down to physician preference, training, and the specific characteristics of the tendon being treated. Both offer a significant advantage over traditional surgery by minimizing tissue trauma and accelerating recovery.

The Power of Integrative Care: Our Multidisciplinary Model

Performing an advanced procedure like percutaneous tenotomy is only one piece of the puzzle. True, lasting healing requires a comprehensive, integrative approach that addresses the patient as a whole. This is the core philosophy of our practice at Injury Medical Clinic.

My unique qualifications as a Doctor of Chiropractic (DC), an Advanced Practice Registered Nurse (APRN), a Family Nurse Practitioner (FNP-BC), and a certified Functional Medicine practitioner allow me to view health through multiple lenses. This is further strengthened by our collaborative structure with Dr. Maria Guadalupe Cardenas, MD, our esteemed Medical Director.

Dr. Cardenas is a Board-Certified Internist with an NPI of #1164426749 and Texas Medical License #J2933. With over four decades of clinical experience, she provides invaluable medical oversight for our practice. This multidisciplinary setup, where an MD and a DC work in tandem, ensures that our patients receive care that is both holistic and medically sound. We integrate the following services to create a powerful, synergistic treatment plan:

1. Medical Oversight and Diagnosis (Dr. Cardenas): Dr. Cardenas’s internal medicine expertise is crucial for screening patients, managing comorbidities, and ensuring advanced procedures are medically appropriate. Her role guarantees the highest standards of patient safety.
2. Functional Medicine Investigation (Dr. Jimenez): Why did the tendon fail in the first place? Functional medicine helps us answer this question. We investigate underlying factors like nutritional deficiencies (e.g., Vitamin C, zinc), systemic inflammation, metabolic dysfunction (like insulin resistance), and hormonal imbalances that can impair tissue repair. Addressing these root causes is essential for preventing recurrence.
3. Integrative Chiropractic Care (Dr. Jimenez): A tendinopathy in the elbow or foot doesn’t exist in a vacuum. It is often linked to biomechanical dysfunction elsewhere in the body. As a chiropractor, I assess and correct kinetic chain imbalances. For example:
   • Tennis Elbow: This is often related to poor mechanics in the shoulder, scapula, and even the thoracic spine. Chiropractic adjustments and soft tissue mobilization can restore proper joint mobility and muscle firing patterns, reducing strain on the elbow.
   • Plantar Fasciitis: This is frequently linked to ankle immobility, tight calf muscles, or even pelvic misalignments that alter gait mechanics. Chiropractic care can address these upstream biomechanical faults. By correcting the body’s overall structure and movement patterns, we offload the healing tendon and create an environment where it is no longer subjected to repetitive microtrauma.
4. Targeted Rehabilitation: Following a procedure like Tenex, the body needs the right signals to rebuild the tendon with strong, organized collagen. Our rehabilitation programs are designed to do just that. We progress patients from gentle range-of-motion exercises to eccentric loading exercises, which are scientifically proven to stimulate collagen synthesis and tendon remodeling (Alfredson et al., 1998). This phase is critical for translating the procedure’s structural fix into functional strength and resilience.

A Patient’s Journey at Our Clinic: From Pain to Performance

Let’s walk through a typical patient journey for someone with chronic tennis elbow:

1. Initial Consultation & Diagnosis: The journey begins with a comprehensive evaluation. This includes a detailed history, physical exam, and diagnostic ultrasound to confirm tendinopathy and pinpoint the exact location of the diseased tissue.
2. Collaborative Review: Dr. Cardenas and I review the case to confirm the diagnosis and ensure the patient is a good candidate for percutaneous tenotomy. We rule out any medical contraindications.
3. Root Cause Analysis: We conduct a functional medicine workup, which may include blood tests to check inflammatory markers, nutrient levels, and metabolic health indicators.
4. The Procedure: We perform the Tenex procedure in our office. The patient walks in and walks out, typically needing only a small adhesive bandage over the entry site.
5. Post-Procedure Care: The initial phase focuses on rest and pain management, then quickly transitions to the active phase.
6. Integrative Chiropractic & Rehabilitation: This is where the magic happens. The patient begins a structured program that includes:
   • Chiropractic adjustments to the spine, shoulder, and wrist to optimize biomechanics.
   • Soft tissue therapies like Active Release Technique (ART) or Graston to address scar tissue in surrounding muscles.
   • A progressive rehabilitation plan starting with gentle isometrics and progressing to the crucial eccentric strengthening exercises.
7. Nutritional & Lifestyle Support: Based on the functional medicine findings, we provide targeted nutritional advice and supplements to support collagen production and reduce systemic inflammation.

By combining the precision of percutaneous tenotomy with the holistic framework of integrative chiropractic and functional medicine, we don’t just eliminate pain; we rebuild a more resilient, functional person. This is the future of musculoskeletal care—a future we are proud to offer our patients in El Paso today.
