Ultrasound-Guided Needle Fenestration & Tenotomy in Raleigh & Cary, NC

​

The Tendon Procedure Without the Brand Name (or the Brand-Name Price)

If you've researched treatments for chronic tennis elbow, Achilles tendinopathy, or plantar fasciitis, you've probably encountered impressive-sounding branded procedures: Tenex (ultrasonic tenotomy) and TenJet (hydromechanical tenotomy). They're marketed as advanced technology — and priced accordingly.

​

Here's what the marketing doesn't emphasize: the underlying goal of all these procedures is the same, and the simplest version — ultrasound-guided needle fenestration (also called needle tenotomy) — achieves comparable results without a proprietary device, without an incision, and at a fraction of the cost. At Carolina Nonsurgical Orthopedics in Raleigh and Cary, NC, needle fenestration is one of our core in-office procedures for chronic tendinopathy.

​

What Is Needle Fenestration / Tenotomy?

Chronic tendinopathy (tennis elbow, Achilles tendinosis, patellar tendinopathy, plantar fasciosis) is usually not inflammation — it's degeneration. The tendon develops disorganized collagen, abnormal blood vessels, and ingrown pain nerves. Rest doesn't fix it because the tissue itself is unhealthy, and the body's healing response has stalled.

Needle fenestration restarts that response. Under continuous ultrasound guidance, the physician makes multiple precise passes with a needle through the degenerative portion of the tendon. Each pass:

• Disrupts the abnormal tissue — breaking up disorganized collagen and pathological neovessels

• Triggers a controlled healing response — the microtrauma converts a stalled, degenerative process into an active healing one

• Allows precise biologic delivery — the same needle track can deliver PRP directly into the treated tissue

The procedure takes 15–20 minutes in the office under local anesthesia. No incision, no sutures, no device console.

​

Needle Fenestration vs. Tenex vs. TenJet: An Honest Comparison

All three procedures share the same therapeutic goal — mechanically disrupt degenerative tendon tissue under ultrasound guidance to restart healing. They differ in how they disrupt it:

What does the evidence say about outcomes? A 2023 systematic review of ultrasound-guided needle tenotomy (12 studies, 481 patients) found that needle tenotomy produced the same outcomes as surgical tenotomy — that conclusion rested on the two studies in the review that made the direct comparison, and surgical tenotomy is the benchmark these device procedures are measured against. Separately, percutaneous ultrasonic tenotomy (Tenex) has also been compared against surgical tenotomy — in a retrospective study — with similar findings. No published trial has directly randomized patients to needle fenestration versus Tenex head-to-head — but with both matching the surgical benchmark, the outcomes land in the same range.

Put plainly: you're paying for the device, not for better results. The branded systems add a proprietary device console, single-use handpieces, and facility fees to achieve what a needle accomplishes under the same ultrasound guidance. For appropriately selected tendinopathy — which is most of it — the evidence doesn't support paying that premium.

Conditions We Treat With Needle Fenestration

• Tennis elbow (lateral epicondylitis / common extensor tendinosis)

• Golfer's elbow (medial epicondylitis)

• Achilles tendinopathy

• Patellar tendinopathy (jumper's knee)

• Plantar fasciitis / plantar fasciosis — often combined with PRP

• Gluteal tendinopathy (greater trochanteric pain)

• Rotator cuff tendinopathy (selected cases)

• Hamstring tendinopathy

​

What to Expect: The Procedure

1. Diagnosis first. We confirm the pain generator with history, exam, and in-office diagnostic ultrasound — fenestration treats degenerative tendon tissue, so we verify that's what we're dealing with.

2. Local anesthesia. The skin and tissue around the tendon are numbed. Most patients report pressure, not pain.

3. Ultrasound-guided fenestration. The physician makes 20–40 controlled needle passes through the abnormal tendon region, watching the needle in real time on ultrasound. When combined with PRP, the biologic is delivered through the same track.

4. Done in 15–20 minutes. A bandage, no stitches. You walk out.

​

Recovery

• First 3–5 days: Soreness at the treatment site is expected — it's the healing response starting. This is normal and temporary.

• Weeks 1–2: Relative rest from the aggravating activity; daily life is fine. No NSAIDs for the first two weeks if PRP was included (they can blunt the healing response).

• Weeks 2–6: Progressive loading and physical therapy to remodel the healing tendon. This phase matters — the procedure restarts healing, but structured loading shapes the result.

• Full return: Most patients return to full activity by 6–12 weeks depending on the tendon and severity.

Unlike Tenex/TenJet protocols that may require bracing, boots, or activity restrictions tied to the incision, needle fenestration's recovery is typically simpler — there's no incision to protect.

When Fenestration Isn't the Answer

Honesty cuts both ways. Needle fenestration is for degenerative tendinopathy — it doesn't fix:

• Complete tendon ruptures (these need surgical evaluation)

• Joint arthritis masquerading as tendon pain (different problem, different treatment)

• Nerve entrapment (e.g., carpal tunnel–type symptoms referred to the elbow)

• Tendon tears with significant retraction or loss of function

This is why the diagnostic step comes first. Treating the wrong structure precisely is still treating the wrong structure.

Frequently Asked Questions

Is needle fenestration the same as dry needling?
Related but different. Dry needling typically targets muscle trigger points with thin acupuncture-type needles. Tendon fenestration uses a larger needle, many more passes, specifically into degenerative tendon tissue under ultrasound guidance, with the goal of disrupting abnormal tissue — not releasing muscle knots.

​

Does it hurt?
The area is numbed with local anesthetic, so the procedure itself is usually well tolerated — most patients feel pressure. Soreness for several days afterward is expected and is actually a sign the healing response has started.

​

How is this different from a cortisone shot?
Cortisone suppresses inflammation (and tendinopathy usually isn't inflammatory — it's degenerative). Steroids can also weaken tendon tissue with repeated use. Fenestration does the opposite: it stimulates a healing response in tissue that has stopped healing on its own.

​

Why would anyone choose Tenex or TenJet then?
Marketing, device availability, and physician training patterns explain most of it. The branded devices are legitimate procedures with real evidence — but the evidence doesn't show them outperforming the needle technique they were designed to improve upon. If a clinic only offers the branded device, that's what gets recommended.

​

Can fenestration be combined with PRP?
Yes — and we often do. The needle track created during fenestration is an ideal delivery route for PRP, placing the biologic directly into the tissue that's been mechanically stimulated. The combination is common in our practice for stubborn tendinopathy.
