Tennis elbow (lateral epicondylitis) is a degenerative tendinosis of the common extensor tendon at the outside of the elbow, not simple inflammation. That is why rest and cortisone often quiet the pain without repairing the tendon. Focused electromagnetic shockwave (ESWT) takes the other approach: it delivers concentrated acoustic energy to the diseased tendon to provoke a healing response, and it is studied directly for this condition in the American Journal of Sports Medicine and pooled in Clinical Rehabilitation. At Dynamic Athlete it is delivered as Dynamic Shockwave+: true focused ESWT plus EMTT every session on the Storz system, layered with Dynamic PRP+ when the tendon needs more.
If you were told to rest it, brace it, or try another cortisone shot, this is the non-surgical step worth understanding first, and how to tell whether a clinic can treat the tendon, not just buzz the surface.
Why focused shockwave fits tennis elbow?
The problem is a degenerated tendon, not inflammation
The old name, lateral epicondylitis, says inflammation. The tissue says otherwise. By the time tennis elbow is chronic, biopsy and imaging show the common extensor tendon is degenerated: disorganized collagen, failed healing, abnormal vessels. That is tendinosis. It explains why an anti-inflammatory masks the pain without fixing the tendon, and why the durable fix gets the tissue repairing again.
Shockwave provokes repair instead of suppressing it
Focused electromagnetic ESWT delivers concentrated acoustic energy to the diseased tendon origin. Rather than quieting inflammation, it provokes the body’s own repair response in stalled tissue. That mechanism is the whole point: cortisone calms; focused shockwave is meant to restart healing. It is why shockwave is typically considered after rest, bracing, and therapy, rather than another steroid injection (Speed, 2014).
It is studied for this exact condition
Tennis elbow is one of the indications focused ESWT has been examined for directly. A randomized controlled trial in the American Journal of Sports Medicine (Rompe, 2004) studied shockwave for chronic lateral epicondylitis in tennis players, and a meta-analysis in Clinical Rehabilitation (Karanasios, 2021) pooled the lateral-elbow trials. We cite this to explain the technology, not to promise a number.
Focused, with a path to PRP if the tendon needs more
Shockwave provokes self-repair, often enough for a degenerated but intact tendon. When the exam shows advanced wear or a partial tear, we layer in Dynamic PRP+, our high-dose, multi-spin PRP (over 10 billion platelets) placed into the tendon by needle under live ultrasound by Dr. Garg. Two angles, one goal: shockwave from outside, the injectate from inside, detailed in our focused shockwave program.
For the tendon: focused ESWT vs radial
| Property | Focused Electromagnetic ESWT | Radial Pressure Wave |
|---|---|---|
| How energy is delivered | A true acoustic shockwave aimed at a defined focal point and depth | A pneumatic pulse strongest at the skin, fading inward, no focal point |
| Depth and dose control | Clinician selects depth and energy to match the tendon | Limited control; energy disperses near the surface |
| What the elbow evidence studies | Most strong lateral-epicondylitis data is built on focused ESWT | Sometimes used, but not the basis of the strongest evidence |
| Classified as shockwave? | Yes (per ISMST, ASMST, ASTI) | A separate technology (per ISMST, ASMST, ASTI) |
Before you book, ask
- Do you have a focused electromagnetic ESWT unit, and what is the manufacturer and model?
- Will a physician examine the elbow and set the depth and dose, or does a technician run a preset on a surface applicator?
- What is the plan if shockwave alone is not enough: can you layer in PRP, and who performs it?
The bottom line
Tennis elbow is a tendon that stopped healing. The tool that helps most is the one built to put energy into that tendon and restart repair, which is why the elbow evidence is built on focused ESWT, not a surface buzz. The clinic that helps you most names the device, sets the dose, and tells you the plan if the tendon needs more. Written by Aneesh Garg, DO, CAQ, The Regen Doc, Founder of ASTI.
Frequently asked questions
Does shockwave therapy work for tennis elbow?
Tennis elbow, also called lateral epicondylitis, is one of the conditions where focused extracorporeal shockwave therapy (ESWT) has been studied directly. A randomized controlled trial in the American Journal of Sports Medicine (Rompe, 2004) examined shockwave for chronic lateral epicondylitis in tennis players, and a systematic review and meta-analysis in Clinical Rehabilitation (Karanasios, 2021) pooled the trials on lateral elbow tendinopathy. The reason it is matched to this problem is structural: tennis elbow is a degenerative tendinosis of the common extensor tendon at the outside of the elbow, and focused ESWT delivers concentrated acoustic energy to that tendon to stimulate a healing response in tissue the body had stopped repairing. We do not promise an outcome. We examine the elbow, confirm the diagnosis, match the dose and focal depth to your tendon, and tell you honestly whether you are a candidate.
Why does cortisone often fail for tennis elbow?
Because tennis elbow is usually not an inflammation problem by the time it becomes chronic. The older name, lateral epicondylitis, implies inflammation, but biopsy and imaging studies show the common extensor tendon is degenerated, not inflamed: disorganized collagen, failed healing, and abnormal blood vessels, a picture better described as tendinosis. A cortisone injection is a powerful anti-inflammatory, so it can quiet pain for a few weeks, but it does not repair degenerated tendon, and some studies link repeated cortisone to worse long-term results. Focused shockwave takes a different approach. Instead of suppressing inflammation, it delivers concentrated acoustic energy to the diseased tendon to provoke the repair process. That is why shockwave is often considered after rest, bracing, and physical therapy, rather than another cortisone shot.
What is the difference between focused shockwave and radial for tennis elbow?
They are different technologies, and many clinics market both under the single word shockwave. Focused electromagnetic ESWT uses an electromagnetic generator to make a true acoustic shockwave with a defined focal point the clinician aims at a chosen depth, so energy concentrates at the common extensor tendon origin. Radial pressure wave uses a pneumatic projectile that strikes the skin; its energy is strongest at the surface and fades inward, with no focal point to aim. The International Society for Medical Shockwave Treatment (ISMST), the American Society for Medical Shockwave Treatment (ASMST), and the American Shockwave Training Institute (ASTI) classify them as distinct technologies. For tennis elbow the tendon origin is close to the surface, so radial is sometimes used, but focused ESWT lets the clinician control depth and dose precisely, and it is the modality most of the strong elbow evidence is built on. At Dynamic Athlete the standard is Dynamic Shockwave+: focused ESWT plus EMTT every session, with radial as an adjunct when indicated.
How many shockwave sessions does tennis elbow usually take?
Most focused ESWT protocols for tennis elbow run as a short series of weekly sessions, commonly in the range of three to five, with reassessment along the way. The exact number depends on how long you have had the problem, how degenerated the tendon is on examination, and how the elbow responds. Tendon healing is gradual, so many people notice the most change in the weeks after the series finishes rather than during it. We do not sell a fixed package sight unseen. We evaluate the elbow, confirm the diagnosis, set a plan matched to your tendon, treat it, and adjust based on response. If the series stalls, we talk openly about layering Dynamic PRP+ or another next step rather than simply repeating the same treatment over and over.
Is shockwave for tennis elbow painful, and is it safe?
Focused ESWT for the elbow is usually felt as a deep, firm tapping that builds as the energy increases, and most people tolerate it without anesthesia, though a tender tennis elbow can be sensitive during treatment. Reported side effects in the literature are generally mild and transient: short-lived soreness, redness, or minor bruising over the treated area. It is non-invasive, with no incision and no injection. Shockwave is not appropriate for everyone; specific situations such as certain clotting disorders, active infection, or pregnancy are screened before treatment. That screening is one reason the person holding the applicator matters. At our clinic a physician evaluates the elbow, confirms you are a candidate, and performs the treatment, rather than handing it to a technician on a preset.
When should shockwave for tennis elbow be combined with PRP?
When the tendon needs more than a stimulus to heal itself. Focused shockwave provokes the body’s own repair response, which is often enough for a tendon that has degenerated but is still structurally intact. When examination shows more advanced degeneration, a partial tear, or a tendon that has not responded to a course of shockwave, we layer in Dynamic PRP+, our high-dose, multi-spin platelet-rich plasma (concentrated 12 to 20 times baseline, over 10 billion platelets) plus Exosome-Containing Fibrin-Rich Plasma, placed precisely into the diseased tendon by needle under live ultrasound. Shockwave and PRP work on the same goal from two angles: shockwave from outside, the injectate from inside. The point of a physician-led evaluation is that you are not locked into one tool. We match the plan to what the tendon actually needs, and Dr. Garg performs the injection himself.
Is shockwave for tennis elbow covered by insurance, and what does it cost?
Most insurance plans, and Medicare, do not cover extracorporeal shockwave therapy for tennis elbow, so it is generally an out-of-pocket service, as it is at most clinics. The consultation or office visit may be billable to Medicare or Kaiser, but the shockwave treatment itself is paid out of pocket. Two things make that more manageable at Dynamic Athlete. First, HSA and FSA dollars typically apply to shockwave therapy, so you can use pre-tax funds. Second, Cherry financing lets you spread the investment over monthly payments rather than paying all at once. We give you the full plan and the cost before anything is scheduled, so there are no surprises. We would rather you understand the investment up front and decide it is worth it than feel rushed into a package.
