The use of Ozone in Chronic Joint Pain

There is a significant amount of research surrounding the use of ozone (o3) in treating various diseases. In this article, we will present some of the research that surrounds the use of ozone gas for problems of chronic pain.

Ozone gas started gaining attention as a treatment for chronic joint pain decades ago. A 1989 study from the University of Bologna in Italy (1) examined the effects of an oxygen-ozone mixture (called medical ozone) injected into patients with knee osteoarthritis.

This research is to illustrate the long years that have been dedicated to the research of ozone. We have more recent research that we will be exploring below.

The concept behind how ozone-oxygen therapy works.

In March 2021, in the journal Biomolecules (2) medical university researchers in Italy gave a broad outline of how ozone-oxygen therapy helps patients with joint pain. Here is what they wrote:

“Several studies have assessed the effects of O2-O3 (Oxygen-Ozone) therapy in different pathological conditions related to musculoskeletal pain. It is widely accepted that pain is a common symptom related to the inflammation process, and Oxygen-Ozone therapy might play a key role not only in the management of inflammation but also in nociceptive perception (the production or reduction of nerve/pain messages) and modulation . . . (There is stimulation or) an increase in serotonin and endogenous opioids (production, the body’s natural painkiller response, which) has been shown after Oxygen-Ozon administration, and these antioxidant molecules could induce pain relief by stimulating antinociceptive pathways (simply the body’s inflammatory response).

Hypoxia (low oxygen levels) and vascularization (blood vessel blockage or disease) impairment are common pathological features in muscle wasting and musculoskeletal disorders; thus the potential role of Oxygen-Ozone therapy in hypoxic tissues may be related to increased production of nitric oxide, adenosine, and prostaglandins, with a resulting positive role in the vasodilatation process.

Taken together, all these findings suggested that oxygen-ozone therapy might exert its positive effects in several tissues due to the moderate oxidative stress produced by ozone interactions with biological components. However, it should be noted that “the thin red line” between O3′s beneficial effects and toxicity could be related to the strength of the oxidative stress.”

In summary: Oxygen-Ozone therapy can work as

Ozone and joint damaging chronic oxidative stress

In June 2021 in the orthopedic journal EFORT Open Reviews (3) researchers examined the anti-oxidative stress aspects of intra-articular ozone injections. They explain:

“The rationale behind the use of intra-articular ozone (O3) therapy arose from the assumption that chronic oxidative stress plays an important role in osteoarthritis. . . Clinical experiences and research have considered ozone gas as a powerful anti-inflammatory, immune-modulatory substance. Due to its high reactivity, it may be able to reduce oxidative stress, stimulate fibroblastic joint repair, and may promote new cartilage growth.”

Ozone gas in musculoskeletal disorders

A detailed and precise analysis of ozone gas and musculoskeletal disorders is presented in the journal Medical Gas Research, September 2018. (4)

Here researchers examined the role of ozone over a myriad of disorders including lumbar facet joint syndrome, subacromial bursitis, carpal tunnel syndrome, hip bursitis, shoulder adhesive capsulitis, herniated disc, and temporomandibular joint disorder. Here are some learning points from that research:

Effectiveness in temporomandibular joint disorder

The researchers found that the use of ozone therapy has been much more effective than medication therapy in patients with the temporomandibular joint disorder and high pain scores. Ozone can relieve pain and increase the maximum voluntary interincisal mouth opening values. The researchers speculated that ozone gas promotes new cartilage growth as well as reduces inflammation.

Effectiveness for herniated disc

The use of ozone directly injected into the disc was explored. Among the main findings was that ozone may be beneficial because it dehydrates the disc and as such would lessen the amount of bulge pressing on the nerves. Ozone therapy also had analgesic and anti-inflammatory effects in treating disk herniation. In a 2017 study, researchers in Italy and Canada published findings in the Journal of the Canadian Association of Radiologists (5) where they reported that patients who can benefit the most from ozone are patients with back pain with or without radicular pain but without motor deficits, which have been non-responsive to 4-6 weeks of conservative therapies. They found that short-term results could be achieved by dehydrating or shrinking the disc.

Effectiveness for shoulder pain

Here the researchers reported on a single case history of a 57-year-old woman who had shoulder pain reduction and increased range of motion. Next, they reported on suggested anti-inflammatory benefits in patients with shoulder adhesive capsulitis.

Effectiveness for hip bursitis

Here the researchers suggested that ozone therapy can be used to alleviate hip pain due to functional overload, trochanteric bursitis, pain caused by initial and late coxarthrosis, and hip tendonitis. It is also helpful to associate oxygen-O3 therapy along with prescribed exercises and a period of rehabilitation.


Prolozone is a Prolotherapy technique developed by Frank Shallenberger, MD, that utilizes ozone gas, along with other therapeutic substances to stimulate healing and reduce pain in injured soft tissues and joints. Dr. Shallenberger describes Prolozone in a 2011 article in the Journal of Prolotherapy as: “a technique that marries concepts from neural therapy, Prolotherapy, and ozone therapy. It involves injecting various combinations of procaine, anti-inflammatory medications/homeopathics, vitamins, minerals, proliferative, and a mixture of ozone/oxygen gas into degenerated or injured joints, and into areas of pain. The result of this combination is nothing short of remarkable in that damaged tissues can be regenerated, and otherwise, untreatable pain can be permanently cured.”(6)

Comparison of Ozone Therapy and corticosteroid injections

A randomized control trial published in the journal Clinical rheumatology (7) compared the effects of ultrasound-guided corticosteroid injection with oxygen-ozone injection in patients with knee osteoarthritis. Here are the learning points:

Comparison of Ozone Therapy and Hyaluronic Acid Injections and dextrose Prolotherapy injections

An October 2018 study in the Journal of Pain Research (8) compared ozone treatments with Hyaluronic Acid Injections or dextrose Prolotherapy injection as the control group.

Please note that this is not a comparison of Prolozone to the other treatments, this is a comparison of ozone alone.

The researchers wrote that “the existing body of evidence had well demonstrated that ozone injection was evidently effective for short-term management (1–3 months) of mild-to-moderate knee osteoarthritis patients (grade I–III KLS). But the main challenge was on longer periods of time in which different studies had declared heterogeneous (or mixed) results.”

The researchers gathered dates from a series of randomized control trials and made these observations:

A 2015 study in the journal Anesthesiology and Pain Medicine (9) showed that:

Ozone injections in combination with dextrose Prolotherapy injections

An August 2021 study in the journal Evidence-Based Complementary and Alternative Medicine (10) examined whether ozone injections in combination with dextrose Prolotherapy injections significantly improved knee problems in patients with osteoarthritis. To do this the researchers aimed to compare the effect of hypertonic saline with ozone and hypertonic saline (as a placebo control) in improving the symptoms of osteoarthritis in the patients.

The researchers found that in the saline injections with ozone and the saline injections without ozone groups, the results were about the same. Both groups did report improvements in pain, stiffness, and function. The researchers concluded: “The results showed that intra-articular prolozone therapy and hypertonic saline injection can lead to improvement of pain and function in patients with knee osteoarthritis at the same status without any significant difference.”

One study: Ozone ineffective made knee worse.

A December 2021 paper (11) in the medical journal Medicine, assessed various non-surgical knee osteoarthritis treatments. Among them was the use of ozone. What these researchers found was ozone injection, when compared to the other treatments, was the only intervention for which knee pain and/or function got worse at the end of the study compared with the baseline. Ozone injection showed no improvement in pain and function at 12 months.


Therapeutic injections of ozone into soft tissue structures, such as muscles, tendons and ligaments as well as arthritic joints for the relief of pain has been utilized for decades in medical clinics around the world. Various case series have been published documenting the analgesic effect of ozone in osteoarthritis. Double­-blind randomized­ controlled studies have also documented the therapeutic effects of ozone in the treatment of low back pain with and without sciatica. As a powerful oxidizing agent, ozone has been found to have a pro­inflammatory as well as an anti­inflammatory effect, depending on the concentration utilized. Its proposed mechanisms for tissue repair and regeneration include the stimulating of growth factor production and release.

In regard to using Ozone as the proliferant in Prolotherapy, here are my thoughts: Earlier in my career I treated many patients with Ozone therapy. I learned Ozone therapy from the then-president of the German Ozone Society (main organization utilizing ozone therapy at the time), Gerd Wasser, M.D. Besides teaching me major autohemotherapy (a treatment where ozone gas is mixed with a patient’s blood outside the body and then injected back into the patient to kill bacteria and virus), direct ozone gas insufflations (where ozone is introduced directly into the body to fight virus), he taught me to inject ozone therapy into joints. I myself received Ozone therapy into my knee joint to try it and have utilized it on some of my patients in the past.

We have pointed out the benefits and comparisons to other treatments in ozone gas or oxygen-ozone treatments. While we do not utilize this therapy we do understand that many people have derived benefits. Why do we not use this treatment? In nearly thirty years of providing regenerative injection injections, we have had the opportunity to assess many treatments. Clinical observation and patient outcomes indicate for many treatments that their effectiveness was no better than treatments that we were already providing and the treatments themselves did not fill a need some of our patients may have had in their difficulty to treat joint pain.
