Exploring how medical ozone is emerging as a powerful tool in preventing post-surgical infections, particularly in orthopedic procedures.
Explore ResearchWhen patients undergo major surgery like total hip replacement, the fear of post-surgical infection looms large. These infections are more than just complications; they can mean prolonged hospital stays, additional surgeries, and in severe cases, life-threatening outcomes.
In the ongoing battle against surgical site infections, a surprising ally has emerged from an unexpected source – ozone therapy. This innovative approach utilizes a carefully controlled mixture of oxygen and ozone gas to protect patients during some of their most vulnerable moments.
Recent research is now revealing how this once unconventional method is carving out a legitimate place in modern infection control, potentially offering a powerful new prophylactic weapon for surgeons fighting the scourge of postoperative infections 1 .
Ozone, a molecule consisting of three oxygen atoms (O³), is often associated with its protective role in the Earth's atmosphere or as a component of smog at ground level. However, in controlled medical applications, ozone reveals a different nature entirely. When administered properly by trained professionals, medical ozone exhibits remarkable therapeutic properties that make it particularly valuable in surgical settings.
Ozone disrupts the integrity of bacterial cell envelopes through oxidation of phospholipids and lipoproteins, effectively inactivating bacteria, viruses, fungi, and protozoa. Even low concentrations are sufficient to neutralize bacterial cells, including their resilient spores 6 .
Through controlled oxidative stress, ozone activates the body's antioxidant defense systems, including enzymes like glutathione peroxidase, catalase, and superoxide dismutase. This "preconditioning" effect enhances the body's ability to manage subsequent oxidative challenges 5 .
These diverse mechanisms make ozone particularly valuable in orthopedic surgeries involving implants, where the presence of foreign material can increase infection risk and where optimal tissue oxygenation is crucial for proper healing.
In 2003, researchers at the Chair and Department of Orthopedics and Traumatology of the Locomotor System at the Medical University in Warsaw embarked on a groundbreaking preliminary study to evaluate ozone's effectiveness in preventing infections during total hip replacement surgery 1 . This investigation was particularly significant as it addressed one of orthopedic surgery's most challenging complications – infections following implant procedures.
The research team developed a prototype apparatus specifically designed for intraoperative ozone therapy and established their own method of administration. After receiving approval from the Bioethics Commission, they implemented their technique in a clinical setting between June and November 2003 1 .
The study followed a comparative design:

| Ozone Therapy | 83 | 4.6 months |
| Control Group | 80 | 4.6 months |

The application of ozone therapy during surgery followed a carefully designed protocol:
The findings from this pioneering study offered compelling evidence for ozone therapy's potential in surgical infection prevention:
These results demonstrated that intraoperative ozone therapy could be safely integrated into orthopedic procedures while potentially offering significant protective benefits against infectious complications 1 .
The medical application of ozone requires specialized equipment and protocols to ensure both efficacy and safety. The Warsaw study utilized a purpose-built prototype, but ozone therapy has since evolved with more standardized approaches.
| Component | Function | Application Considerations |
|---|---|---|
| Ozone Generator | Produces precise ozone-oxygen mixtures | Must deliver consistent concentrations; typically 20-40 μg/mL for medical use |
| Application Apparatus | Delivers ozone to target areas | Design varies by application method (direct gas, ozonated saline, etc.) |
| Safety Systems | Prevents ozone exposure to operating room | Ensures safety of patients and staff; prevents respiratory exposure |
| Concentration Controls | Maintains therapeutic levels | Critical for efficacy and avoiding toxicity; typically 20-40 μg/mL |
The concentration of 20 μg/mL used in subsequent studies for wound treatment has shown effectiveness while maintaining an excellent safety profile 6 .
The promising results from the Warsaw hip replacement study have contributed to a growing interest in ozone therapy across various surgical and medical disciplines:
A 2024 multicenter randomized trial in Italy is investigating ozone therapy combined with antibiotics for treating infections following orthopedic prosthesis implantation. This study aims to determine if the combined approach is superior to antibiotics alone, particularly important in an era of rising antibiotic resistance 3 .
A 2019 case report documented successful use of topical ozone therapy for a severe spinal surgery infection that had proven resistant to conventional antibiotics and surgical debridement. After adding ozone treatments twice weekly for three weeks, the patient's wound completely healed, with no recurrence of infection during a full year of follow-up 6 .
A 2025 animal study revealed ozone therapy's potential to prevent heterotopic ossification (abnormal bone growth in soft tissues) following hip surgery. Rats receiving ozone prophylaxis showed significantly reduced heterotopic ossification compared to controls – 30% versus 100% incidence – suggesting ozone's anti-inflammatory properties may disrupt the pathological process 2 .
The preliminary study on intraoperative ozone therapy for hip replacement surgeries opened a promising avenue in surgical infection prevention. While researchers rightly caution that "the usefulness of the proposed technique of ozone therapy in prophylaxis of early septic complications after elective orthopedic reconstructive surgery still needs further clinical investigation" 1 , the initial results are undoubtedly encouraging.
As orthopedic surgery continues to advance with increasingly complex procedures and implants, the need for effective infection prevention grows correspondingly. Ozone therapy, with its multifaceted mechanism of action, favorable safety profile, and potential cost-effectiveness, represents a compelling candidate for addressing this persistent surgical challenge.
Future large-scale randomized controlled trials will be essential to firmly establish ozone therapy's place in the standard surgical armamentarium, but the current evidence suggests that this once unconventional approach may soon become mainstream medicine.
The story of ozone therapy exemplifies how sometimes solutions to modern medical challenges can come from unexpected places, reminding us that innovation in medicine often requires looking at familiar substances through a new lens.
