Before you commit to shockwave therapy – and the time, cost, and sessions that come with it – you want to know something fundamental: will the results last?
It’s a fair question. Nobody wants to invest in a treatment that provides temporary relief only to have the pain return six months later. The honest answer is that it depends on the condition, whether you address the underlying cause, and individual factors. But the long-term follow-up data we do have is largely encouraging.
What “Permanent” Means in Medical Context
First, a reality check on expectations. In medicine, few treatments produce truly permanent results for chronic conditions. Even surgery doesn’t guarantee permanent resolution – knee replacements eventually wear out, repaired tendons can re-tear, and spinal fusions can develop adjacent segment disease.
The more useful questions are:
- How long do results typically last?
- What percentage of patients maintain improvement over time?
- What factors affect durability?
- What happens if symptoms recur?
Here’s what the evidence shows for the conditions most commonly treated with extracorporeal shockwave therapy (ESWT).
Plantar Fasciitis: Generally Durable Results
Long-term follow-up studies for ESWT in chronic plantar fasciitis are among the most reassuring in the shockwave therapy literature.
A study by Gerdesmeyer et al. (2008, American Journal of Sports Medicine) followed patients for 12 months after ESWT and found that improvements in pain and function were maintained or continued to improve beyond the initial treatment period. Several other studies with 12-24 month follow-up confirm this pattern.
The available data suggests that 70-80% of patients who respond to ESWT for plantar fasciitis maintain their improvement at one to two years. This is comparable to or better than the durability of corticosteroid injections, which often provide short-term relief that fades within 3-6 months.
Why plantar fasciitis results tend to last: ESWT promotes structural tissue remodeling – new blood vessel formation, collagen reorganization – that creates lasting changes in the plantar fascia rather than just masking pain. If the patient also addresses contributing factors (footwear, stretching, weight management), the structural improvements persist.
Calcific Shoulder Tendinitis: Often Permanent
This may be the condition where ESWT produces the most durable results. When high-energy focused ESWT successfully breaks down calcium deposits in the rotator cuff tendons, that calcium resorption is typically permanent – the deposits don’t reform in most cases.
Studies with follow-up periods of 2-5 years show maintained calcium resorption and associated pain relief in the majority of successfully treated patients. The structural change (calcium removal) is a one-time event, and the symptom relief correlates directly with the structural outcome.
Tennis Elbow: Durable but Context-Dependent
For lateral epicondylitis (tennis elbow), long-term results depend heavily on whether the patient modifies the activity that caused the problem in the first place.
Studies show that patients who respond to ESWT generally maintain improvement at 12 months. However, patients who return to the same repetitive stress patterns without ergonomic changes, load management, or strengthening are more likely to experience recurrence.
This is not a limitation of ESWT specifically – it’s a reality of any treatment for overuse injuries. The treatment heals the tissue, but the biomechanical cause must also be addressed.
Erectile Dysfunction: Maintenance May Be Needed
The durability question is most debated for low-intensity shockwave therapy (Li-SWT) for erectile dysfunction. The results timeline for shockwave therapy varies more for this condition than for musculoskeletal applications.
Some studies show maintained improvements in International Index of Erectile Function (IIEF) scores at 12 months after treatment. Others suggest that benefits may begin to diminish at 6-12 months, leading some providers to recommend maintenance sessions at periodic intervals.
The difference likely relates to the underlying cause. ED caused by vascular insufficiency may respond to ESWT’s neovascularization effects, but those new blood vessels need ongoing physiological support. If the underlying metabolic factors (diabetes, cardiovascular disease, lifestyle) aren’t addressed, the vascular improvements may not persist indefinitely.
What Determines Whether Results Last
Across all conditions, several factors influence how durable ESWT results are:
Addressing the root cause. This is the single biggest factor. Shockwave therapy treats the tissue damage, but if the cause of that damage continues (overuse, poor biomechanics, metabolic disease), recurrence is more likely. ESWT combined with rehabilitation, activity modification, and lifestyle changes produces more durable outcomes than ESWT alone.
Treatment completeness. Patients who complete the full recommended course (typically 3-6 sessions) have better long-term outcomes than those who stop early. The biological healing processes ESWT initiates need sufficient stimulus to produce lasting structural change.
Condition severity. Patients with more advanced tissue degeneration or longer symptom duration before treatment may have less durable results. Early intervention generally produces better long-term outcomes.
Individual biology. Healing capacity varies. Factors like age, blood supply, nutritional status, smoking, diabetes, and medication use (e.g., corticosteroids, fluoroquinolones) can influence tissue healing and repair durability.
When Results Do Fade
If symptoms recur after initially successful ESWT, options include:
- Reassessment to determine whether the same condition has recurred or a different problem has emerged
- Repeat ESWT – a second course of treatment is an option, typically after waiting 3-6 months from the initial course
- Combined approaches – adding rehabilitation, ergonomic changes, or other treatments that weren’t part of the initial plan
- Alternative treatments if repeat ESWT is unlikely to add benefit
Recurrence doesn’t mean the initial treatment failed. It may mean the underlying cause wasn’t fully addressed, or the condition is inherently recurrent (as some tendinopathies are in athletes who continue high-load training).
Discuss realistic long-term expectations for your specific condition with a qualified provider, and ask what you can do to maximize durability.
The Bottom Line
Shockwave therapy results are generally durable for musculoskeletal conditions, with most patients maintaining improvement at 12-24 months. Calcific tendinitis results are often permanent. Plantar fasciitis and tendinopathy improvements typically persist when patients address the underlying cause. ED outcomes may require periodic maintenance. The treatment produces real structural tissue changes, not just temporary pain masking – but no treatment can guarantee permanent results if the root cause goes unaddressed.
