Cortisone Shots Vs. Regenerative Injections: Why is One a Band-Aid and the Other a Fix?
Here is the truth!
Doctors around the world routinely administer corticosteroid (cortisone) injections and refer to it as “what you need.” Many do not mention that repeated cortisone can, in some joints and tendons, accelerate decline—including cartilage loss, tendon weakening, and a faster progression of degeneration. There is a significant body of research and real-world evidence showing both the short-term benefits and the long-term risks of cortisone.
Regenerative injections are different. They are designed to stimulate your body’s own repair processes instead of just masking pain. These treatments can encourage cell activity, collagen production, blood vessel growth, and tissue remodeling. The trade-off: they usually take longer to work and are often out of pocket.
This guide clearly explains how cortisone shots and regenerative injections work, what the science says (including potential harms), what to expect, and which questions to ask your doctor. The goal is straightforward: to help you make an informed decision that aligns with your symptoms, goals, and budget.

Key Takeaway
Most people are recommended cortisone shots by their doctor, but don’t even realize that it has clinical studies to back that it actually will further destroy the knees, damage the cartilage and tendons, and actually progress degeneration in the knees rather than even helping..
Regenerative injections aim for gradual, longer-term healing by triggering your body’s natural repair. Relief builds over weeks to months, not hours to days.
Your choice should match your goals: quick symptom relief vs lasting tissue repair. Decide with your doctor after weighing both benefits and risks for your specific condition.
Glossary (quick meanings)
Osteoarthritis (OA): Wear-and-tear arthritis where joint cartilage breaks down, causing pain and stiffness..
Intra-articular: Inside a joint (e.g., a knee injection).
Cartilage: Smooth “cushion” on bone ends inside a joint. Tendon / Tendinopathy: A tendon connects muscle to bone; tendinopathy = irritated or degenerating tendon.
Bursitis: Inflammation of a fluid-filled sac (bursa) that cushions joints.
Synovitis: Inflammation of the joint lining.
Osteophytes: Bone spurs that can form around an arthritic joint.
Effusion: Extra fluid in a joint (swelling).
Avascular necrosis (AVN): Bone damage from poor blood supply (rare with local injections).
PRP (Platelet-Rich Plasma): Your blood, spun to concentrate platelets/growth factors, injected to support healing.
Mesenchymal stem cells (MSCs): Repair-supporting cells from bone marrow or fat used in some regenerative therapies.
BMAC: Bone Marrow Aspirate Concentrate—bone-marrow–derived cells and factors used for repair support.
Prolotherapy: Dextrose (sugar) injections that trigger a mild healing response to strengthen tissue.
Paracrine signaling: Cells “talk” by releasing signals that guide nearby cells to heal.
Angiogenesis: Formation of new blood vessels (better blood supply for healing).
Collagen: The Main protein that gives tendons/ligaments strength.
ESWT (Shockwave therapy): Acoustic pressure waves are applied to tissue to reduce pain and stimulate repair.
Class IV laser (Photobiomodulation): Therapeutic light to support cell metabolism and reduce inflammation.
Kellgren–Lawrence (KL) grade: X-ray scale (1–4) showing how severe OA is.
The Traditional Approach: Cortisone Injections
What cortisone does: Picture an inflamed joint like a fire. Cortisone is a powerful anti-inflammatory—a fire extinguisher. Injected into a joint, tendon sheath, or bursa, it reduces inflammation fast, often easing pain within 24–72 hours.
Benefits (What the science supports)
Strong short-term relief for flares of knee osteoarthritis, bursitis, tendon sheath irritation, and some nerve compression syndromes (e.g., carpal tunnel).
Improved function in the near term, often for weeks to a few months.
Widely covered by insurance and familiar to most clinics.
Important limits and potential harms
Temporary relief and masking: Cortisone treats inflammation, not the root cause (tissue damage, instability, poor mechanics). Feeling better can lead to overuse and worse injury.
Cartilage loss & OA progression: Studies published in journals like Radiology (2017)and JAMA (2017) have shown repeated intra-articular cortisone to accelerate cartilage loss and faster osteoarthritis progression, even if pain improves short term.
Tendon weakening & rupture: Corticosteroids can impair collagen and slow tendon repair, increasing the risk of partial or full tendon tears (Achilles, patellar, rotator cuff) American Journal of Sports Medicine (2006), For conditions like “tennis elbow,” while cortisone may offer faster initial pain relief, a study in JAMA (2013) found that patients had worse long-term outcomes (higher recurrence rates and poorer full recovery) at one year compared to those who opted for physical therapy alone, suggesting it may hinder long-term healing
Bone risk: Repeated steroids have been associated (rarely) with avascular necrosis (loss of blood supply to bone). Infection risk: As with any injection, there is a small risk of joint infection; steroids can further suppress the immune response.
Other side effects: Blood sugar spikes (for people with diabetes), skin changes at the injection site, and cortisone flare (temporary pain increase).
Frequency limits: Most clinicians cap injections in the same area to 3–4 per year due to these risks.
Plain truth: Cortisone is useful for short-term relief, not long-term healing.
The Newer Approach: Regenerative Injections
Core idea: Instead of only calming inflammation, regenerative injections aim to activate healing—supporting cell activity, blood flow, collagen formation, and tissue remodeling. This approach targets root causes like degenerating cartilage, weakened tendons/ligaments, and joint instability.
How regenerative injections work
They deliver biological signals (growth factors, cells, or controlled irritants) to the injured area to restart or amplify the body’s repair response. This can reduce pain by improving tissue quality, not just numbing the signal.
Main types
1) Platelet-Rich Plasma (PRP)
What it is: Your own blood is drawn and spun in a centrifuge to concentrate platelets (rich in growth factors).
How it helps: Platelets release PDGF, TGF-β, VEGF, IGF-1, and more—signals that promote cell growth, new blood vessels, collagen synthesis, and pro-healing inflammation.
Evidence & uses:
Knee osteoarthritis (mild–moderate): Multiple randomized trials and reviews show meaningful pain and function gains for 6–12 months or longer, often outperforming hyaluronic acid.
Chronic tendinopathy (tennis elbow, jumper’s knee, Achilles): PRP often shows better mid- to long-term outcomes than cortisone, with lower recurrence.
What it is: Uses mesenchymal stem/stromal cells (MSCs) from bone marrow or fat (or perinatal sources).
How it helps: MSCs can differentiate and, more importantly, signal other cells via paracrine effects (growth factors, cytokines, exosomes) to reduce harmful inflammation, improve blood supply, and recruit repair.
Evidence & uses: Encouraging results for knee OA and focal cartilage defects; research continues on doses, delivery, and durability. Often considered when PRP isn’t enough or when damage is more advanced.
3) Prolotherapy (dextrose)
What it is: Injections of hypertonic dextrose to ligaments/tendon insertions.
How it helps: Creates a controlled, mild inflammatory signal that triggers healing cascades and collagen production, helping stabilize joints and reduce pain.
Evidence & uses: Supportive data for chronic low back pain (ligament laxity), certain tendinopathies, and joint instability.
4) Shockwave Therapy (ESWT)
What it is: Acoustic pressure waves delivered to the painful area (focused or radial shockwaves). No injections.
How it helps: It can stimulate blood vessel formation, modulate pain, and trigger tissue remodeling in tendons and fascia.
Evidence & uses: Widely used for plantar fasciitis, calcific and non-calcific rotator cuff tendinopathy, lateral epicondylitis, and patellar tendinopathy. Often part of a rebuild plan with loading/physio.
What to expect: 3–6 sessions spaced 1–2 weeks apart; discomfort during treatment is common; improvements build over 4–12 weeks. Usually self-pay.
5) Class IV Laser Therapy (Photobiomodulation)
What it is: A high-power therapeutic laser applied to tissues (non-invasive). How it helps: Light energy can enhance cellular metabolism, reduce inflammatory mediators, improve microcirculation, and support tissue repair.
Evidence & uses: Used for tendinopathy, arthritis pain, muscle strains, and post-injury recovery. Evidence varies by protocol, device, and dosing; best as part of a multi-modal program (loading/physio).
What to expect: 8–12 short sessions are common; usually painless with no downtime; typically self-pay.
What to expect with regenerative injections:
Onset:Gradual—benefits build over weeks to months as tissues remodel.
Plan: Often includes targeted physical therapy and activity progression to protect and strengthen healing tissue.
Coverage: Commonly not covered by insurance; expect out-of-pocket costs that vary by clinic and protocol.
Safety: Generally well-tolerated; side effects are usually mild and temporary (soreness, swelling). For stem cell harvesting, the procedure is more involved.
Cortisone vs Regenerative Injections: Side-by-Side
Slower onset, higher upfront cost, variable protocols; stem cell harvest is more invasive
Best Fit
Acute flare, quick relief needed, infrequent use
Chronic degeneration, desire for long-term repair, ready to invest time/resources
Your Path Forward: Make a Shared Decision
Choosing between cortisone vs regenerative injections is personal. The “right” option depends on:
Diagnosis & severity: Where is the damage? How advanced is the arthritis or tendon disease?
Goals: Do you need fast relief now, or do you want to build lasting repair even if it’s slower?
Budget & coverage: Are you prepared for out-of-pocket costs if you choose regenerative care?
What you’ve tried: Have rest, PT, bracing, activity changes, weight loss, or previous injections helped?
Lifestyle & timeline: Do you have time to follow a progressive rehab plan and protect the area while it heals?
Smart Next Steps
Cortisone is a fast Band-Aid that can help in the short term—especially for painful flares—but it does not repair tissue and can harm cartilage and tendons with repeated use. Regenerative injections are a repair-focused option that builds results gradually and can support better tissue quality and function over time. Choose the path that matches your goals, timeline, and values, and decide with your doctor—not just for quick relief, but for your long-term health.
Get a clear diagnosis (exam + imaging as needed).
Discuss both the benefits and risks of cortisone and regenerative options for your exact case.
Align the plan with your goals and timeline.
Pair injections with a targeted rehab program to protect gains.

Q: Can I get both a cortisone shot and a regenerative injection?
A: Sometimes—but usually not at the same visit. A cortisone shot may be used first to calm a severe flare. A regenerative injection can follow once the acute phase settles. Giving both at once may blunt the regenerative response. Your doctor will advise on timing.
Q: Why don’t insurance companies cover regenerative injections if they look promising?
A: Insurers typically require large, long-term trials before coverage. PRP already has strong evidence for some uses (like knee OA and tendinopathy), but coverage often lags behind research. As more high-quality data accumulates, coverage may expand.
Q: How do I find the right doctor for regenerative injections?
A: Look for board-certified orthopedic, sports medicine, or pain specialists with specific training in regenerative medicine. Ask about their experience, protocols, outcomes, and use of ultrasound or fluoroscopy for precise placement.
Q: Are there activity limits after regenerative injections?
A: Yes. Expect reduced activity for days to weeks to protect the area. Your plan often includes structured physical therapy to guide a safe return and strengthen healing tissue.
Q: How many regenerative injections will I need?
A: It varies. PRP is often 1–3 sessions a few weeks apart. Stem cell therapy can be a single or series depending on severity. Prolotherapy often involves multiple sessions over weeks to months. Your clinician will tailor the plan.
