- Cortisone suppresses. Prolozone provokes. One silences the healing signal; the other deliberately triggers it and supplies what repair requires.
- Repeated cortisone can weaken tissue — including the cartilage it was meant to protect. That is a known trade-off and one patients are rarely told about.
- Poor circulation is why joints do not heal. Ozone improves local oxygen delivery, which is exactly the deficit in avascular tissue.
- Most people need three to six sessions, spaced one to three weeks apart. A single injection rarely tells you much.
- G6PD is screened before any ozone therapy, including this one. One inexpensive test, done once in a lifetime.
How prolozone actually works
The name is a compound of prolotherapy and ozone, and understanding both halves explains the mechanism.
Prolotherapy is an old idea: inject something mildly irritating into a damaged ligament or joint, provoke a controlled inflammatory response, and the body treats the area as an injury requiring repair. Fibroblasts arrive, collagen is laid down, and the tissue strengthens. It sounds counterintuitive to deliberately cause inflammation in a painful joint, and it works because the inflammation is acute and self-limiting rather than chronic.
The ozone adds two things. It improves local oxygen delivery, which matters enormously in tissue that is poorly vascularised to begin with. And it triggers the same hormetic antioxidant response that systemic ozone does, locally, in the tissue that needs it.
Alongside both, the injection carries procaine or lidocaine for immediate comfort, plus vitamins and minerals — typically B vitamins, magnesium and trace minerals — because the repair being prompted requires raw materials to complete.
So you are provoking repair, improving the oxygen supply that repair depends on, and delivering the materials it needs, in one injection.
Suppression versus repair
Prolozone, cortisone and PRP compared
These are not competitors so much as different tools. There are situations where a patient needs relief quickly and cortisone is the right call. What concerns me is cortisone used repeatedly over years as the only offering, when the mechanism actively works against the tissue over that timeframe.
PRP sits in similar territory to prolozone — platelet-rich plasma drawn from your own blood and injected to deliver growth factors. It has more published evidence than prolozone and it costs considerably more. Where budget allows and the indication fits, PRP is a reasonable choice; where a patient needs several joints treated or several sessions, prolozone is often the more practical route.
What responds best, and what does not
Being clear about this saves patients money and disappointment.
Responds well: ligament laxity and old sprains that never fully resolved, mild to moderate osteoarthritis, chronic tendinopathy, sacroiliac and low back pain of ligamentous origin, plantar fasciitis, tennis and golfer's elbow, and the shoulder that has ached since an injury years ago.
Responds less well: bone-on-bone end-stage arthritis, where there is little cartilage left to work with. Acute severe injury requiring surgical repair. Pain that is primarily neuropathic rather than structural. And any joint where the underlying driver — a metabolic one, an autoimmune one — has not been addressed.
That last point matters more than people expect. A knee inflamed by systemic inflammatory load will respond poorly to a local injection while that load persists. Which is why we look at the metabolic and inflammatory picture alongside, rather than treating the joint as though it exists in isolation.
The ten problems prolozone is used for
Ranked by how reliably they respond.
Knee Osteoarthritis
The most common indication and among the most reliable responders in mild to moderate disease. Improved oxygen delivery to poorly vascularised cartilage plus a prompted repair response addresses the actual mechanism rather than only the symptom.
What the evidence showsProlozone combines ozone with procaine and nutrients, prompting a controlled local inflammatory and repair response rather than suppressing pain signalling as corticosteroid injection does.Chronic Low Back and Sacroiliac Pain
Where the origin is ligamentous rather than disc-related, prolozone frequently does what years of anti-inflammatories did not. The sacroiliac joint in particular is a common source that is often missed entirely.
What the evidence showsCorticosteroid injections provide short-term relief but have been associated with accelerated cartilage loss on imaging with repeated use, which is the central argument for regenerative rather than suppressive approaches.Shoulder Pain and Rotator Cuff
Partial thickness tears and chronic impingement respond well. Full thickness tears are a surgical conversation, and we will say so rather than treating something that needs repairing.
What the evidence showsOzone increases local oxygen availability and stimulates growth factor release including TGF-beta, supporting collagen synthesis in ligament and tendon.Plantar Fasciitis
Notoriously stubborn and notoriously slow, which is exactly the profile of a stalled healing process. Frequently combined with shockwave, and the combination outperforms either alone in our experience.
What the evidence showsRandomised and controlled studies of intra-articular ozone in knee osteoarthritis have reported improvements in pain and function scores comparable to hyaluronic acid injection.Tennis and Golfer's Elbow
Chronic tendinopathy at the elbow is one of the clearest examples of a healing process that started and stopped. Prompting it to restart is precisely the mechanism.
What the evidence showsLigament laxity contributes to joint instability and accelerated degeneration, and prolotherapy approaches target the ligamentous structures rather than only the joint surface.Neck Pain and Cervical Instability
Where ligamentous laxity is contributing, strengthening those structures addresses the cause rather than managing the consequence. Requires careful assessment and appropriate imaging first.
What the evidence showsProcaine included in the injection provides immediate analgesia and has independent anti-inflammatory properties through effects on neural signalling.Hip Osteoarthritis
Responds, though less predictably than the knee because the joint is deeper and technically harder to access accurately. Image guidance improves results considerably.
What the evidence showsThe nutrients included — typically B vitamins, magnesium and trace minerals — supply cofactors required for local collagen synthesis and tissue repair.Ankle Instability and Old Sprains
An ankle sprained badly years ago and never properly rehabilitated leaves lax ligaments and recurring problems. This is the classic prolotherapy indication and it remains one of the best.
What the evidence showsImage guidance materially improves injection accuracy, and blind intra-articular injection has documented miss rates that vary substantially by joint.Hand, Wrist and Thumb Arthritis
Small joints respond well and are straightforward to treat. Thumb base arthritis in particular affects function disproportionately and responds better than most patients expect.
What the evidence showsThe treatment is repeated in a series because collagen remodelling proceeds over weeks, and successive treatments build on the repair response initiated by the previous one.TMJ and Jaw Pain
A less common application and one that requires specific expertise, but the jaw joint is a joint and the same principles apply. Worth considering where dental approaches have not resolved it.
What the evidence showsProlozone is considerably less expensive than cellular regenerative approaches and addresses the same underlying goal of prompting local repair, making it a reasonable first-line regenerative option.What people commonly experience with this therapy
When patients receive the proper guidance, here is what people commonly experience with it.
- The first 48 hours — some soreness. The mechanism is a deliberate inflammatory response, so mild soreness afterwards is expected and is a sign it is working. We ask patients to avoid anti-inflammatories during this window, because those would suppress the exact process we are trying to create.
- Week 1–2 — the first improvement. Most patients notice something after the first injection, though rarely the full effect. The local anaesthetic gives immediate relief that wears off; what follows is the beginning of the repair response.
- Sessions 2–4 — the substantive change. This is where most of the benefit accumulates. Each session builds on the last, which is why a single injection tells you very little and a course of three to six is the honest recommendation.
- Months 3–6 — durability and function. The measure that matters. Range of motion, walking distance, ability to train, and how much pain medication is still needed. Many patients go a year or longer before considering a top-up.
If you have been told to take an anti-inflammatory and come back when the joint is bad enough for surgery, there is a great deal of ground in between. Schedule a consultation and let my team assess the joint properly, look at what is driving the inflammation systemically, and tell you honestly whether prolozone is the right option. We will not stop until the root cause of every one of your health issues has been found and addressed.
A proper assessment of the joint, the systemic drivers alongside it, and an honest answer about whether this will help you.
Common questions
What is prolozone therapy?
An injection combining local anaesthetic, vitamins and minerals, and medical ozone, delivered into a joint, ligament or soft tissue. Rather than suppressing inflammation the way cortisone does, it provokes a controlled healing response, improves local oxygen delivery and supplies the raw materials that repair requires.
How is prolozone different from a cortisone shot?
They work in opposite directions. Cortisone suppresses inflammation, which relieves pain quickly and, with repeated use, can weaken the tissue including cartilage. Prolozone deliberately provokes a controlled repair response, which is slower to take effect and aims to strengthen the tissue rather than degrade it.
How many prolozone treatments will I need?
Typically three to six, spaced one to three weeks apart. Each session builds on the last, so a single injection rarely tells you much. Many patients then go a year or more before considering a top-up, depending on the joint and the underlying condition.
Does prolozone hurt?
The injection itself is brief and the local anaesthetic works immediately. What most patients notice is mild soreness for a day or two afterwards, which is expected — the mechanism is a deliberate inflammatory response. We ask you to avoid anti-inflammatories during that window, because they would suppress the process we are trying to create.
Where can I get prolozone injections near Nashville?
At our clinic in Franklin, Tennessee, about twenty minutes south of downtown Nashville and minutes from Brentwood and Cool Springs. We screen G6PD before any ozone therapy and we assess the systemic inflammatory drivers alongside the joint itself.
