Cortisone and shockwave trade the lead. In a 2024 meta-analysis of six randomized trials in Orthopaedic Surgery, corticosteroid injection led at one month for chronic tennis elbow, and extracorporeal shockwave therapy (ESWT) led at three and six months. A separate meta-analysis found shockwave ahead of corticosteroid for plantar fasciitis at three months. One caution: the strong deep-tendinopathy evidence base rests on focused ESWT. Radial pressure wave is a distinct, more superficial technology per ISMST, ASMST, and ASTI classification. At Dynamic Athlete in Boulder, Colorado, Dynamic Shockwave+ delivers true focused ESWT plus EMTT on the Storz gold-standard system, performed by Aneesh Garg, DO, CAQ, the ISMST-certified founder of ASTI.
For the patient weighing a cortisone shot against a shockwave series: what each does, when each leads in the randomized data, and the device question to ask before paying for either.
The Decision
Choose cortisone when the next month is the mission and the target is a joint or bursa where a steroid is standard care. Near tendon the calculus tightens: relief is temporary, the tendinopathy is unchanged, and the one-year record argues restraint.
Choose focused shockwave when the goal is the tendon itself. It asks for a defined series over weeks, and it earns the lead at months three and six. Verify what you are buying first: the manufacturer-and-model question below applies anywhere, including here.
Key Takeaways
- The lead changes hands on a schedule. A 2024 meta-analysis of 6 randomized trials (chronic tennis elbow): corticosteroid ahead at 1 month; ESWT ahead at 3 and 6 months on pain and function.
- Plantar fasciitis reads the same direction. A meta-analysis of randomized trials found shockwave ahead of corticosteroid injection on pain at three months.
- Cortisone’s one-year record argues for restraint near tendon. In a JAMA trial of tennis elbow, recurrence after cortisone was 54% at one year, versus 12% with placebo.
- Radial is not shockwave. ISMST, ASMST, and ASTI classify focused ESWT and radial pressure wave as distinct technologies, and the strong published evidence for deep tendinopathy and calcific tendonitis rests on focused.
- With Dynamic Shockwave+, over 90% of our patients self-report a 75% or greater improvement, all without surgery. HSA and FSA dollars typically apply, and Cherry financing can spread the investment.
Meta-Analysis of 6 Randomized Trials · Orthopaedic Surgery 2024
Month 1 vs Months 3–6
For chronic tennis elbow, corticosteroid injection led at one month. Focused shockwave led at three and six months on pain and function. The comparison is a timeline, not a tie.
When does each option lead in the trials?
The randomized record is a crossover story; the crossover sits near month three.
Cortisone: fast, real, and short
A corticosteroid suppresses inflammatory signaling, so relief arrives in days. But chronic tendinopathy is largely degenerative, and the steroid does not change the tendon. The Coombes JAMA trial measured what follows: one year after cortisone for tennis elbow, recurrence was 54%, versus 12% with placebo. Clinicians also commonly avoid steroid near weight-bearing tendons such as the Achilles.
Focused shockwave: slower, and built for the tendon
Focused acoustic energy is delivered into the tendon to provoke a repair response. The trial pattern matches the mechanism: in the Zhang meta-analysis, ESWT trailed cortisone at one month and led at three and six. For plantar fasciitis, the Xiong meta-analysis found shockwave ahead on pain at three months. Slower start, longer arc.
The device question decides what you actually receive
The word “shockwave” is not regulated as a marketing term. The strong published evidence for deep tendinopathy rests on focused ESWT; radial pressure wave is a separate, more superficial technology per ISMST, ASMST, and ASTI classification. If a clinic offers only radial, that is not shockwave. Dynamic Shockwave+ delivers true focused electromagnetic ESWT plus EMTT every session on the Storz system.
Who performs it, and what stands behind them
The physician who teaches the method is the physician on your case. Aneesh Garg, DO, CAQ is ISMST-certified (ICC, ISMST World Congress 2026, Madrid), an ASMST member, and Founder and Medical Director of ASTI, where clinicians and physicians train on focused ESWT. If acoustics are not enough, escalation to Dynamic PRP+ happens under the same physician.
How do cortisone and Dynamic Shockwave+ compare?
| Property | Cortisone Injection | Dynamic Shockwave+ (Focused ESWT + EMTT) |
|---|---|---|
| Mechanism | Suppresses inflammatory signaling | Stimulates a tissue repair response |
| Time course | Days to relief; fades over weeks | Series over weeks; leads at months 3–6 in trials |
| Tendon tissue | Unchanged; caution near weight-bearing tendons | The tissue is the target |
| Repeat profile | 54% one-year recurrence in the JAMA tennis-elbow trial | Defined series, physician-dosed |
| Device standard | n/a | Focused electromagnetic ESWT, Storz system; radial only as adjunct |
| Escalation path | Repeat injection | EMTT stacked; Dynamic PRP+ under the same physician |
Before you pay for “shockwave” anywhere
Paying for shockwave and receiving radial is not a detail. The strong published evidence for deep tendinopathy rests on focused ESWT. Ask for the manufacturer and model first. A clinic delivering true focused shockwave answers without hesitation.
Which three questions verify a shockwave clinic?
Print this. Ask it on the phone.
- Is your device focused ESWT, and what is the manufacturer and model?
- Who trained you: ASTI, ISMST, or ASMST, and is a physician directing treatment?
- If shockwave alone is not enough, can you escalate to PRP or cell-based options under the same physician?
Frequently asked questions
Is shockwave therapy better than a cortisone shot for tendon pain?
It depends on which month you care about. In a 2024 meta-analysis of six randomized trials in chronic lateral epicondylitis (tennis elbow), corticosteroid injection produced better pain and function scores at one month, and extracorporeal shockwave therapy produced better scores at three and six months. A separate meta-analysis of randomized trials in plantar fasciitis found shockwave ahead of corticosteroid on pain at three months. So cortisone is the faster tool and shockwave is the more durable one in these datasets, which is exactly what their mechanisms predict: one suppresses the pain signal, the other provokes tissue repair. At Dynamic Athlete, Aneesh Garg, DO, CAQ maps that timeline to your season, work, and imaging before recommending either. Individual results vary.
How fast does each option work?
Cortisone typically changes pain within days, with the peak effect in the first weeks; that speed is its entire advantage, and in the randomized data the advantage is gone by month three. Focused shockwave runs as a series of sessions over several weeks, and improvement builds during and after the series rather than overnight; the trials show its lead at three and six months. The practical translation: if you have an event in two weeks, that argues one direction. If you want the tendon better next season, that argues the other. The evaluation exists to place your case on that timeline honestly, including the cases where neither option is the right first move.
Why is cortisone used cautiously near tendons?
Two reasons, both in the published record. First, the rebound: in the JAMA randomized trial of tennis elbow, patients who received a corticosteroid injection had lower full-recovery rates at one year than patients who received placebo (83% versus 96%) and far higher recurrence (54% versus 12%). Relief now was traded against the year. Second, tissue concern: chronic tendinopathy is a degenerative process, and clinicians commonly avoid injecting steroid around load-bearing tendons such as the Achilles because of long-standing concerns about tendon integrity after steroid exposure. None of this makes cortisone a bad drug; it makes it a short-term tool whose use near tendon deserves an explicit plan for what happens when it wears off.
Is radial pressure wave the same as the shockwave used in these studies?
No. The International Society for Medical Shockwave Treatment (ISMST), the American Society for Medical Shockwave Treatment (ASMST), and the American Shockwave Training Institute (ASTI) all classify focused extracorporeal shockwave and radial pressure wave as distinct technologies. Focused ESWT concentrates acoustic energy at a defined focal point deep in tissue; radial pressure wave disperses energy superficially from the skin surface. The strong published evidence base for deep tendinopathy and calcific tendonitis rests on focused ESWT. Radial has legitimate superficial uses, but a clinic that owns only a radial unit and markets it as shockwave is not delivering focused ESWT. Ask for the manufacturer and model before booking; Dynamic Shockwave+ runs focused electromagnetic ESWT on the Storz system, with radial only as an adjunct.
How many shockwave sessions does tendon pain typically take?
Focused shockwave is dosed as a series, not a single event. Published protocols for chronic tendinopathy commonly run several sessions spaced about a week apart, and the trials that measured shockwave ahead of cortisone at three and six months used defined multi-session courses. The exact number for your case depends on the tendon involved, how chronic the problem is, the energy settings your tissue tolerates, and how your pain and function respond across the series, which is why Dr. Garg sets the plan at the evaluation and adjusts it against your response rather than selling a fixed package. Expect the meaningful readout weeks after the series begins, not the next morning. Individual results vary.
Can shockwave and cortisone be combined?
Generally not at the same tissue at the same time, and sequencing matters. A steroid quiets the local inflammatory signaling that focused shockwave deliberately provokes as part of its repair mechanism, so stacking them at once works against the point of the shockwave series. If you have recently had a cortisone injection, Dr. Garg reviews what was injected, where, and when, and times the shockwave course accordingly. The reverse order is more natural: a patient whose cortisone has worn off is often exactly the patient for whom a focused ESWT series, or escalation to high-dose Dynamic PRP+, is considered next. Bring your full injection history to the evaluation; the plan is built around it.
What is Dynamic Shockwave+ and who performs it?
Dynamic Shockwave+ is the shockwave protocol at Dynamic Athlete in Boulder: true focused electromagnetic ESWT plus EMTT (extracorporeal magnetotransduction therapy) every session, on the Storz gold-standard system, with radial pressure wave added only as an adjunct when indicated. It is directed by Aneesh Garg, DO, CAQ, who is ISMST-certified (Instructional Certification Course, ISMST World Congress 2026, Madrid), a member of ASMST, and the Founder and Medical Director of the American Shockwave Training Institute, where clinicians and physicians across the field train on focused ESWT. If shockwave alone is not enough for your tendon, the escalation path to high-dose PRP or cell-based options runs under the same physician in the same building. Candidacy is assessed honestly at the evaluation.
