Focused Shockwave Therapy for Degenerative Knee Arthritis
Clinical Evidence & Research on Shockwave Therapy
Understanding Degenerative Knee Arthritis
Degenerative knee arthritis, or osteoarthritis of the knee, is a progressive joint condition characterized by cartilage breakdown and bone changes. This condition commonly affects older adults and those with high physical demands, causing pain, stiffness, and functional limitations. Focused shockwave therapy has emerged as a non-invasive treatment option for managing degenerative knee arthritis.
Focused shockwave therapy, also known as extracorporeal shock wave therapy (ESWT), has emerged as a promising non-invasive treatment approach for degenerative knee arthritis. This therapy uses high-energy acoustic waves to stimulate natural healing processes within the body.
About Focused Shockwave Therapy
Focused shockwave therapy, commonly referred to as ESWT, is a non-invasive therapeutic technique that delivers high-energy mechanical waves to targeted tissue areas. The therapy has a decades-long history in clinical applications and has been extensively researched across multiple medical disciplines.
Pulse Wave™ is the name of one focused shockwave device. It is not another name for the therapy, and none of the studies on this page used it.
Key characteristics of focused shockwave therapy include:
- Non-invasive delivery of mechanical energy to tissue
- Stimulation of natural biological healing processes
- Reduction of pain and inflammation
- Promotion of tissue regeneration and repair
- Well-established safety profile in clinical applications
Clinical Study Overview
Study Reference
Study Title: The effects of ESWT on the pain and function of patients with degenerative knee arthritis
Authors: Lee JH, Lee S, Choi SJ, Choi YH, Lee K
Journal: Journal of Physical Therapy Science (2017) 29(3): 536-538
PMID: 28356649
DOI: 10.1589/jpts.29.536
Study Design & Methodology
Study Type: Two-group comparison, 10 patients per group. The paper does not say patients were randomised.
Sample Size: 20 patients (ages 55-70 years) with Grade 2 Kellgren-Lawrence (KL) arthritis
Treatment Protocol: 1000 pulses at 4 Hz, 3x/week for 4 weeks
This study used a focused shockwave device from another manufacturer. It did not use Pulse Wave. 20 patients were divided into two groups of 10.
Outcome Measurements
The study utilized validated clinical outcome scales to measure treatment effectiveness across multiple dimensions including pain reduction, functional improvement, and quality of life measures. These standardized instruments allow for comparison with other treatment approaches and provide clinically meaningful data.
Key Findings
VAS pain score: 7.9→2.9 (ESWT) vs 6.8→5.5 (control)
K-WOMAC functional score: 37.4→9.3 (ESWT) vs 30.9→25.4 (control), p<0.05
Significant improvements in pain and functional mobility
Summary of Results
| Outcome Measure | ESWT Group | Control Group | P-Value |
|---|---|---|---|
| Pain Score (VAS) | Significant improvement | Lesser improvement | p<0.05 |
| Functional Score | Substantial improvement | Minimal improvement | p<0.05 |
How Focused Shockwave Therapy Works for Degenerative Knee Arthritis
Focused shockwave therapy stimulates biological healing mechanisms in osteoarthritic knee joints. The mechanical waves may promote cartilage repair signaling, reduce inflammatory mediators, and increase synovial fluid production. By stimulating these healing pathways, ESWT may help slow progression and improve joint function in degenerative knee arthritis.
The therapeutic effect of focused shockwave therapy is thought to involve multiple biological pathways working synergistically. Understanding these mechanisms provides insight into why ESWT can be effective for various conditions including degenerative knee arthritis.
Biological Effects:
- Neovascularization: Creation of new blood vessel networks to improve tissue perfusion
- Angiogenesis: Growth of new blood vessels for enhanced nutrient delivery
- Mechanotransduction: Cellular response to mechanical stimulation
- Anti-inflammatory signaling: Reduction of inflammatory mediators
Frequently Asked Questions
Is Pulse Wave the same thing as shockwave therapy?
No. Shockwave therapy is the treatment. Pulse Wave™ is one focused shockwave device. The research on this page studied shockwave therapy with other devices. None of it used Pulse Wave.
How long does focused shockwave therapy treatment take?
Treatment duration varies depending on the specific condition and treatment protocol. Typical sessions last 15-30 minutes, with most protocols involving multiple sessions over several weeks. The exact number of sessions and frequency will depend on your specific condition, the severity of symptoms, and individual response to therapy. Your healthcare provider will determine the appropriate treatment schedule.
Is focused shockwave therapy painful?
Focused shockwave therapy is generally well-tolerated. During treatment, you may experience mild to moderate sensations at the treatment site. Most patients find the procedure tolerable without requiring anesthesia or significant pain relief. Any temporary discomfort typically resolves quickly after the session.
How soon can I expect results from shockwave therapy?
Timeline for results varies among individuals. Some patients report symptom improvement within days to weeks of starting treatment, while for others, maximal benefits develop over several weeks to months. Consistent treatment following the prescribed protocol optimizes outcomes. Clinical research suggests peak efficacy often occurs within 4-12 weeks post-treatment initiation.
What are the side effects of focused shockwave therapy?
Focused shockwave therapy has an excellent safety profile with minimal adverse effects. Some patients may experience temporary mild redness, swelling, or discomfort at the treatment site, which typically resolves within hours to days. Serious side effects are rare when treatment is administered by qualified healthcare professionals using appropriate protocols and devices.
Additional Clinical Context
Both groups had standard physical therapy, and one group also had shockwave. Pain and function scores fell in both groups and fell more in the shockwave group. Results were measured after four weeks.
This clinical evidence supports focused shockwave therapy as a valuable non-invasive option for managing degenerative knee arthritis. The research demonstrates measurable improvements in both pain and functional outcomes, making shockwave therapy a significant addition to the treatment landscape for this condition.
