Steroid shots helped at first, but the pain came back? That’s one of the most common things patients tell a Chicago rheumatologist. The reason usually isn’t the shot itself. Steroid injections treat inflammation, but they don’t fix the problem that causes many cases of arthritis pain: joint instability.
In this guide, you’ll learn what causes wear-and-tear arthritis and why steroid injections and nerve-burning procedures often give only short-term relief. You’ll also learn how orthobiologic treatments like PRP therapy and prolotherapy can provide longer-lasting joint pain relief.
Quick Answer: Why Do Orthobiologics Last Longer Than Steroid Shots?
Orthobiologic treatments can give longer-lasting relief because they do more than calm inflammation. They help strengthen the ligaments that hold a joint together, which makes the joint more stable. Steroid injections and radiofrequency ablation can reduce pain, but they don’t improve stability. When the underlying instability is still there, the pain often comes back.
Key takeaways:
- Wear-and-tear arthritis (osteoarthritis) is mainly a problem of instability
- Steroid injections reduce inflammation but don’t stabilize the joint
- Radiofrequency ablation quiets a nerve but doesn’t stabilize the joint
- Orthobiologics (prolotherapy, PRP, bone marrow concentrate) can reduce inflammation longer term and strengthen ligaments
- Pairing treatment with strengthening exercises gives the best long-term results
A Patient Question That Started This Conversation
After watching one of our videos about SI joint pain, a viewer shared that they’d had prolotherapy and enjoyed good pain relief for 12 years. They asked whether that’s typical, and why it happens.
Results vary from person to person, and one patient’s experience isn’t a guarantee for everyone. The reason relief like that is possible comes down to how arthritis develops in the first place.
What Really Causes Osteoarthritis Pain? Joint Instability
Many people think of osteoarthritis as cartilage simply “wearing out” with age. In regenerative medicine, we look at it differently. Wear-and-tear arthritis is a condition of instability.
How Instability Leads to Chronic Joint Pain
- Ligament injury. At some point, the ligaments supporting the joint are injured, sometimes so slightly that you don’t remember it.
- Ligament laxity. The injured ligaments become loose.
- Chronic instability. The joint moves more than it should.
- Tissue breakdown. That extra movement gradually damages the surrounding tissue, bone, and joint.
- Chronic pain. The result is ongoing pain, often worse with activity or stress on the joint.
The Treatment Principle
If the problem is instability, the treatment should improve stability. This one principle explains why some arthritis treatments wear off quickly and others can last much longer.
Steroid Injections and Radiofrequency Ablation: Short-Term Tools
These treatments have a place in chronic pain management, but it helps to know what they can and can’t do.
Steroid (Cortisone) Injections
- ✅ Reduce inflammation
- ✅ Can provide pain relief
- ❌ Don’t strengthen ligaments
- ❌ Don’t improve joint stability
Radiofrequency Ablation (RFA)
- ✅ Heats (“burns”) a nerve so it stops sending pain signals
- ✅ Can reduce pain
- ❌ Doesn’t strengthen ligaments
- ❌ Doesn’t improve joint stability
Because neither option addresses the instability, the pain often comes back.
What Are Orthobiologic Treatments?
Orthobiologics are a core part of regenerative medicine in Chicago and across the country. These treatments use natural substances to support the body’s healing response. Common options include:
- Dextrose prolotherapy: a concentrated dextrose (sugar) solution injected into weakened ligaments
- Platelet-rich plasma (PRP therapy): a concentrated portion of your own blood platelets
- Bone marrow concentrate: a concentrate made from your own bone marrow
How Orthobiologics Help Arthritis Pain
1. They reduce inflammation longer term.
Orthobiologics can calm inflammation over a longer period, rather than giving only temporary relief.
2. They strengthen ligaments and improve stability.
This is the key difference. Treating the ligaments can make them stronger. Even a small gain in ligament strength creates a more stable joint, and a more stable joint is less painful under stress and activity.
Steroids vs. RFA vs. Orthobiologics: Side-by-Side Comparison
| Treatment | Reduces Inflammation | Reduces Pain | Improves Stability | Relief Profile |
|---|---|---|---|---|
| Steroid injection | Yes | Yes | No | Often short-term |
| Radiofrequency ablation | No | Yes | No | Temporary |
| Prolotherapy | Yes, longer term | Yes | Yes | Can be longer-lasting |
| PRP therapy | Yes, longer term | Yes | Yes | Can be longer-lasting |
Prolotherapy vs. PRP Therapy: Which Is Right for You?
Prolotherapy: A Strong First-Line Option
Prolotherapy is a good first-line osteoarthritis treatment for many joint problems, including SI joint dysfunction.
- Usually given once a month
- Most patients need at least a few, sometimes several, treatments
PRP Therapy: More Power for More Instability
For patients with more joint damage or more instability, PRP therapy is the stronger option. In general, what takes about three prolotherapy treatments can often be achieved with one PRP treatment.
A rheumatology specialist trained in regenerative medicine can examine your joint and recommend the right approach for your condition, activity level, and goals.
The Missing Piece: Strengthening Exercises
The best long-term results come from improving stability in all its forms:
- Orthobiologic treatment strengthens the ligaments from within
- Targeted strengthening exercises build the muscles that support the joint
Together, they work toward two goals: lasting pain relief and better function in everyday life.
Frequently Asked Questions
How long does prolotherapy relief last?
It varies by person and condition. Because prolotherapy aims to strengthen ligaments and improve joint stability, relief can be longer-lasting than the short-term relief many patients get from steroid injections. Some patients, like the viewer mentioned above, report years of relief.
Is PRP better than a cortisone shot?
They work differently. A cortisone shot reduces inflammation for a while but doesn’t improve stability. PRP therapy can reduce inflammation longer term and help strengthen ligaments, which is why it may provide more durable relief for instability-related arthritis.
How many PRP or prolotherapy treatments will I need?
Prolotherapy usually involves monthly treatments, typically a few to several sessions. PRP is stronger, so one PRP treatment can often achieve what takes about three prolotherapy sessions.
Can prolotherapy help SI joint pain?
Yes. Prolotherapy is considered a good first-line option for SI joint dysfunction, as well as many other osteoarthritis-related joint problems.
Do I still need physical therapy or exercise after orthobiologic treatment?
Yes. Strengthening exercises are an important part of improving stability and getting the best long-term result.
