SoftWave therapy is a clinically supported, nonsurgical option for many patients with chronic knee pain, particularly osteoarthritis and tendon-related conditions. Delivered over a short course of sessions, it aims to reduce pain and restore function by triggering the body’s own repair mechanisms rather than cutting into the joint. The evidence behind it, while still maturing, is consistent enough that it can be considered a legitimate first step before surgical referral.
TL;DR:
- SoftWave therapy provides significant pain relief for knee osteoarthritis, especially in moderate cases, with an average pain reduction of 2 points on a 10-point scale.
- A typical treatment course involves three to six in-office sessions spaced about a week apart, with most patients experiencing minimal discomfort and no downtime.
- Combining SoftWave with physical therapy or orthobiologic injections enhances outcomes, outperforming single-modality approaches in pain reduction and functional improvement.
- The therapy is generally safe, with mild soreness or redness as common side effects, but it is not suitable for active infections, fractures, or pregnancy.
- Since insurance coverage is inconsistent, costs are usually self-pay, and patients should expect that ongoing treatments may be necessary to maintain benefits.

What Is SoftWave Therapy and How Does It Work?
SoftWave therapy uses unfocused, electrohydraulically generated acoustic waves that travel broadly through soft tissue rather than converging on one small target. That distinguishes it from focused shockwave devices, which concentrate energy at a specific depth, and from radial systems, which disperse energy right at the skin’s surface. SoftWave’s broader field lets it reach ligaments, tendons, and joint capsule tissue around the knee in a single pass.
The biological effect starts with mechanotransduction: mechanical energy from the pulses gets converted into cellular signals that kick off repair activity. From there, several processes appear to unfold, according to mechanistic reviews of shockwave therapy in knee osteoarthritis:
- New blood vessel formation (angiogenesis) that improves circulation to under-nourished tissue.
- Reduced sensitivity of pain-signaling nerve fibers, called nociceptors, which can lower pain perception fairly quickly.
- Recruitment of the body’s own progenitor and stem cells to areas of degeneration or injury.
Those pathways explain why patients often notice pain relief before any structural healing could plausibly show up on imaging. If you want the full mechanical breakdown, our clinic covers it in more depth in how SoftWave therapy works to heal injured tissue.
What Knee Conditions Does SoftWave Treat?
SoftWave has the strongest track record for knee osteoarthritis across a range of severity, from early cartilage wear to more advanced grades. It’s also commonly used for degenerative meniscal tears, patellar tendinopathy (sometimes called jumper’s knee), prepatellar or infrapatellar bursitis, and lingering pain or scar tissue adhesions after knee surgery.
Where SoftWave is less reliable is end-stage cartilage loss, where bone-on-bone contact limits how much symptom relief soft-tissue stimulation can provide. It works best as a symptom-management and function-restoring tool, not a cartilage regrowth solution.
You’re generally a better candidate if you’ve already tried conservative measures like physical therapy or anti-inflammatory medication without lasting relief, and if you’re hoping to avoid or delay surgery. Reviewing your osteoarthritis staging with your provider helps set realistic expectations before you start.
Does the Clinical Evidence Support SoftWave for Knee Pain?
The research on extracorporeal shockwave therapy (ESWT), the broader category SoftWave belongs to, is genuinely encouraging for knee osteoarthritis pain relief. A systematic review and meta-analysis of trials through October 2022 found ESWT produced meaningfully greater pain reduction than sham treatment across short, medium, and long-term follow-up.
Statistic Callout: Pooled trial data show a mean pain reduction of 2.0 points on a 10-point visual analog scale compared with sham treatment (95% CI: 1.5 to 2.5 points), according to the meta-analysis published in 2022.
A separate umbrella review pooling multiple meta-analyses confirmed improvements not just in pain scores but in WOMAC function scores, range of motion, and Lequesne index ratings, with a favorable safety profile throughout. That kind of convergence across independent reviews is what gives clinicians confidence recommending it.
Outcomes aren’t uniform, though, and protocol matters enormously. A network meta-analysis of 69 randomized controlled trials identified medium-energy focused shockwave therapy combined with physical therapy as among the most effective regimens for both pain and function, ahead of low-energy or radial-only protocols used in isolation.
| Evidence type | Key finding | Practical takeaway |
|---|---|---|
| Meta-analysis (2022) | VAS pain reduced by 2.0 points vs. sham | Pain relief is measurable and durable across follow-up periods |
| Umbrella review (2024) | Improved WOMAC, ROM, Lequesne scores | Benefits extend beyond pain into daily function |
| Network meta-analysis (69 RCTs) | Medium-energy focused ESWT plus PT ranks highest | Combining SoftWave with rehab outperforms either alone |
The limitations are real. Many trials use inconsistent energy settings, session counts, and follow-up windows, which makes it hard to compare studies apples-to-apples. Whether ESWT actually modifies the underlying disease process, meaning it slows cartilage breakdown rather than just easing symptoms, remains unproven in humans. The honest bottom line: expect consistent symptomatic benefit, and know that the specific protocol your provider uses genuinely changes your results.
What Happens During a SoftWave Treatment Course?
A typical SoftWave course runs a handful of short in-office visits, most commonly spaced about a week apart. Each session focuses on the knee for roughly ten to fifteen minutes.
- Your provider applies a coupling gel and positions the handpiece over the treatment area.
- You’ll feel a rhythmic tapping or pulsing sensation. Most patients tolerate it well, though tender areas can feel more intense.
- There’s no anesthesia, no incision, and no recovery downtime. You can typically resume normal activity the same day.
- Mild soreness or light redness over the treated area sometimes shows up in the following day or two, then resolves on its own.
- Your provider tracks progress using pain scores and functional testing at each visit, adjusting the plan if early sessions aren’t producing change.
Pro Tip: Track your pain level on a simple 0 to 10 scale before each session. Patterns that emerge over three or four visits tell your provider far more than how you feel on any single day.
Cost is usually self-pay, since SoftWave and similar regenerative therapies aren’t uniformly covered by insurance the way surgical procedures are. Ask about pricing and financing options when you schedule through our SoftWave therapy page.
How Much Improvement Should You Realistically Expect?
Translating the research into plain terms: most patients who respond to SoftWave notice a meaningful drop in pain, often in the range the meta-analyses report, along with better ability to walk, climb stairs, or get through daily tasks without the knee “giving out” on them.
- Patients with moderate osteoarthritis or tendon-related pain tend to respond best.
- Those with bone-on-bone joint collapse or significant mechanical instability usually see more limited benefit.
- Adding supervised physical therapy alongside SoftWave consistently outperforms either approach alone, according to the network meta-analysis of ESWT regimens.
Statistic Callout: Reviews pooling ESWT trials report a favorable safety profile alongside sustained functional gains, though the exact durability varies by protocol and patient severity, per the umbrella review on ESWT for knee osteoarthritis.
Some patients benefit from a maintenance session every several months, particularly if osteoarthritis is progressive. This isn’t a one-and-done fix for a degenerative condition. It’s a tool you may return to periodically.
Is SoftWave Therapy Safe? Side Effects and Limitations
SoftWave carries a favorable safety profile overall. The review summarizing safety data across ESWT trials found adverse events were typically mild and short-lived.
- Local soreness or tenderness lasting a day or two after treatment is common and expected.
- Brief redness or warmth over the treated skin can occur.
- Serious complications are rare in pooled trial data.
That said, SoftWave isn’t appropriate for everyone. Providers generally avoid treating over an acute fracture, an active infection, a known malignancy, or directly over a pregnant patient’s abdomen. One genuine limitation in the field: researchers still don’t report device settings consistently across studies, which makes it harder to say exactly which protocol works best for which patient. Choosing a provider who documents and standardizes those settings matters more than the marketing around any particular device.
How Does SoftWave Compare to Other Nonsurgical Knee Treatments?
SoftWave’s advantages are straightforward: it’s noninvasive, requires no downtime, and carries solid evidence for symptomatic relief without the risks that come with injections or surgery.
- Compared with corticosteroid or hyaluronic acid injections, SoftWave avoids needle-related risks but generally requires more total visits.
- Compared with PRP or other orthobiologic injections, SoftWave is less invasive but may work better as a complement than a replacement in more advanced cases.
- Cost and insurance coverage remain the main tradeoffs, since coverage is inconsistent and outcomes depend heavily on the specific protocol used.
- Combining SoftWave with physical therapy, or sequencing it with orthobiologic treatment, is a reasonable strategy for patients who haven’t responded to either alone. Our guide to non-surgical orthopedic treatments walks through how these options fit together.
When Should Knee Pain Be Referred for Surgery Instead?
SoftWave and other nonsurgical approaches deserve a fair trial, generally several weeks to a few months, before surgery enters the conversation. But some signs call for prompt surgical evaluation rather than continued conservative care.
- Joint instability, a knee that locks or catches, or visible deformity.
- Suspected infection, marked by fever, warmth, and swelling.
- No meaningful improvement in pain or function despite a full nonsurgical course.
SoftWave can delay or, for some patients, eliminate the need for surgery. It is not a substitute for reconstruction or replacement when the joint itself is structurally failing.
A Clinician’s View on Using SoftWave in Practice
At our Regenerative Medicine Clinic, we typically start patients on a three to six session SoftWave pathway, layering in physical therapy or PRP when the exam supports it. Every discovery visit includes a functional assessment and, where relevant, a review of prior imaging, so we can track objective progress rather than guessing. If pain or instability persists despite that trial, we move the conversation toward surgical referral rather than stretching out a treatment that isn’t working.

How to Explore SoftWave Therapy at Nowak Orthopedic Associates
SoftWave is offered alongside PRP, orthobiologic injections, and guided stretch therapy in one coordinated Regenerative Medicine Clinic, allowing patients to avoid piecing together care across separate providers. A discovery consultation starts with a review of your knee history: bring any recent imaging, a summary of treatments you’ve already tried, and a clear description of when your pain flares up. From there, a session plan tailored to your specific diagnosis is developed rather than a generic protocol.
If chronic knee pain has you weighing surgery against “just living with it,” there’s a middle path worth investigating first. Learn more about our Regenerative Clinic or schedule your first visit to find out whether SoftWave fits your situation.

FAQ
Does SoftWave therapy really work on knees?
Meta-analyses of shockwave therapy indicate improved pain reduction and function compared with sham treatment for knee osteoarthritis, with outcomes varying based on protocol and patient severity.
How much does a single SoftWave knee session typically cost?
Pricing varies by clinic and is commonly self-pay rather than insurance-covered; contact your provider directly, such as through Nowak Orthopedic’s SoftWave page, for current rates.
What is the best nonsurgical treatment for knee pain?
There’s no single best option for every patient. Evidence supports SoftWave, physical therapy, and orthobiologic injections, and combining SoftWave with supervised physical therapy tends to outperform either approach alone.
Can SoftWave heal a meniscal tear?
SoftWave is commonly used for degenerative meniscal tears to reduce pain and inflammation, but it addresses symptoms and tissue signaling rather than mechanically repairing a torn meniscus, and outcomes vary by tear severity.
