Search “what can stem cell therapy treat” and you will find lists that run from knee pain to Alzheimer’s to “everything.” That is exactly the problem. Some of those claims rest on real research. Others rest on marketing.
This guide takes a different approach. It walks through nine ailments that stem cell therapy is commonly used for in regenerative medicine, and for each one it tells you what the research shows, who tends to be a good candidate, and where the limits are. It is written for people in Miami who want a straight answer before they spend money or time.
One word of honesty up front: the word “treat” needs care. For most of the conditions below, stem cell therapy is investigational, meaning it is not an FDA-approved treatment for that use. “Can treat” here means “is used for, and has at least some research support.” It does not mean “cures.”
What Can Stem Cell Therapy Treat?
Stem cell therapy is most commonly used in regenerative medicine for joint and orthopedic problems, such as knee osteoarthritis, and has early research for some spine, tendon, nerve and hair conditions. The only uses the FDA has approved for stem cell products are cord blood-derived blood-forming cells for certain blood disorders and one mesenchymal stem cell product for a specific pediatric transplant complication. For the nine conditions in this guide, results vary, the evidence ranges from moderate to early, and stem cell therapy is not a guaranteed cure. Anyone who tells you it can treat “almost anything” is overselling.
What “Stem Cell Therapy” Means in This Guide
In orthopedic and regenerative clinics, “stem cell therapy” usually means one of three things:
- Bone marrow aspirate concentrate (BMAC): cells and growth factors drawn from your own bone marrow.
- Adipose (fat)-derived cells: from your own fat tissue.
- Donor-derived products: such as umbilical cord-derived preparations, subject to regulatory rules that vary by product.
These are not interchangeable. See our guides on how mesenchymal stem cells are harvested, bone marrow vs. umbilical cord stem cells and autologous stem cell therapy for the differences, and our overview of regenerative medicine in Miami.
1. Knee Osteoarthritis
Why it is first: Knee osteoarthritis is the most studied use of stem cell injections in orthopedics, and the most commonly treated.
What research shows. A 2025 meta-analysis in the Journal of Orthopaedic Surgery and Research pooled 8 treatment arms from 6 randomized trials (abstract here) involving 300 patients and found a moderate-to-large improvement in WOMAC scores (a standard knee symptom measure) at 12 months after a single mesenchymal stem cell injection. Interestingly, doses of 25 million cells or fewer were associated with improvement, and higher doses did not do better.
But another 2025 meta-analysis in Frontiers in Medicine (PDF) looked at 8 randomized trials of single MSC injections and came to a more cautious conclusion: most of the symptom improvement could be attributed to contextual effects (the placebo response and the effect of being treated), with MSCs adding a modest extra benefit. The authors rated the certainty of evidence as low, noted small early-phase trials, and called for larger studies.
What this tells you. Both papers are honest, and both are right in their way: stem cells in the knee may help, the benefit seems to be real but smaller than marketing implies, and a significant part of what patients feel may come from the whole treatment experience. That is not a reason to dismiss it. It is a reason to set realistic expectations.
Who tends to do better: Mild to moderate arthritis, some remaining cartilage, active patients who want to delay or avoid surgery.
Who tends to do worse: Severe bone-on-bone arthritis, significant deformity, or major instability.
2. Hip Osteoarthritis
What it is: Wear and tear of the hip joint that causes groin or thigh pain, stiffness and reduced motion.
What research shows. Evidence for stem cells in hip arthritis is thinner than for the knee. Most patient experience and small studies come from knee data and are applied to the hip. That means any promise should be modest.
What helps most: Starting early, protecting the joint, building strength, and discussing all options with an orthopedic specialist. If the joint is severely damaged, a hip replacement is a safe and effective choice for many people. Our balanced guide on stem cell therapy vs. hip replacement explains the tradeoffs.
3. Rotator Cuff Tears and Shoulder Problems
What it is: The rotator cuff is a group of tendons that stabilizes the shoulder. Tears can come from injury or gradual wear.
What research shows. A 2024 review in the International Journal of Molecular Sciences (abstract) found promising laboratory and animal results, noting that mesenchymal stem cells appear to reduce inflammation and improve tendon remodeling. In humans, however, evidence is “varied and limited”: some studies suggest lower retear rates after surgical repair, but randomized trials have produced mixed results. The authors describe cell-based therapies as having an “excellent safety profile” while saying more rigorous trials are needed to prove they improve outcomes.
What this means: Stem cells may support healing, particularly as an add-on to surgery or for partial tears, but they cannot rebuild a large, fully retracted tear.

4. Tendon Injuries: Tennis Elbow, Achilles and Plantar Fasciitis
What they are: Chronic tendon problems, often called tendinopathy, develop when a tendon cannot repair micro-damage fast enough. Common examples are tennis or golfer’s elbow, Achilles tendon pain and plantar fasciitis in the foot.
What research shows. Tendons heal slowly because they have limited blood supply, which is why regenerative approaches are attractive. Research on stem cell injections for tendinopathy is early and limited, with small studies and varied methods. PRP is often studied alongside stem cells for these conditions and has a larger evidence base.
Realistic expectations: For many tendon problems, the first-line approach is still load management, physical therapy and sometimes shockwave or other procedures. Regenerative treatment is typically considered when those have not worked.

5. Degenerative Disc Disease and Chronic Low Back Pain
What it is: Discs between the vertebrae lose water and height with age and wear, sometimes causing chronic low back pain.
What research shows. A 2021 systematic review and meta-analysis in Stem Cells International (abstract) pooled randomized trials of mesenchymal stem cell therapy for degenerative disc disease. It found significant reductions in pain (SMD −0.50) and disability (SMD −0.27), with pain improvements seen at several time points. But it also found a higher rate of treatment-related adverse events in the stem cell group (odds ratio about 3), meaning safety needs attention alongside the benefit. The authors described the evidence base as limited and controversial before concluding that it may be a novel option.
What this tells you: There is a real signal, but it is not a settled answer, and spinal injections are a more delicate procedure than a knee injection. Who performs it and how matters.

6. Meniscus and Cartilage Injuries
What they are: The meniscus is the knee’s shock-absorbing cartilage cushion. Cartilage lesions are areas where the smooth joint surface is damaged.
What research shows. Cartilage has very limited ability to heal, so this area attracts a lot of interest. Stem cell research here is early, and results depend heavily on the type of tear (a degenerative tear in an older knee is very different from an acute tear in a young athlete) and the technique used. Cartilage regeneration has been shown in laboratory work, but proof that injections can rebuild cartilage in people is limited.
Realistic expectations: Stem cell treatment may reduce symptoms and support the joint environment in selected cases, but it should not be expected to regrow a large missing piece of cartilage or fix a mechanically locked tear that needs surgery.

7. Avascular Necrosis (AVN) of the Hip
What it is: Loss of blood supply to the bone, causing part of the femoral head to die and sometimes collapse.
What research shows. AVN is one of the better-studied uses of bone marrow-derived cells, in early stages. A 2025 meta-analysis in Frontiers in Pharmacology (full text) pooled 15 studies (954 hips) and found that adding regenerative therapy to core decompression reduced the risk of femoral head collapse (risk ratio 0.55) and conversion to hip replacement (risk ratio 0.59) compared with core decompression alone. The authors noted high variability between studies, short follow-up and possible publication bias, and called the effect on slowing progression “uncertain.”
What this means: The best data are for early-stage disease, with cells placed into the bone at the time of surgery. Advanced collapse is unlikely to respond.

8. Peripheral and Diabetic Neuropathy
What it is: Damage to peripheral nerves causing numbness, tingling, burning pain or weakness, most often in the feet and hands.
What research shows. A 2024 systematic review and meta-analysis in Stem Cell Research & Therapy (abstract) pooled 7 controlled human trials of stem cell therapy for diabetic peripheral neuropathy, using bone marrow mononuclear cells and umbilical cord-derived MSCs, mainly injected into muscle. It reported improvements in nerve conduction velocity and in symptom scores, with side effects limited to injection-site pain and swelling that resolved within days. The authors called it promising but said further research is needed.
Important context: With only seven small trials, the evidence is early. Nerve conduction numbers are not the same as feeling better, and neuropathy caused by diabetes also requires blood sugar control, which no injection can replace.

9. Hair Loss (Pattern Thinning)
What it is: Gradual shrinking of hair follicles, most commonly androgenetic alopecia in men and women.
What research shows. A 2023 systematic review in Cells (full text) examined 15 studies with 653 participants using mostly fat-derived stem cell products. Several studies showed increased hair density, but the studies were too varied to pool and only 9 of 15 had a control group. The authors called it “a promising treatment option” and called for better-designed studies.
What this means: It may help some people with early thinning, mainly through growth-factor signaling, not by growing brand-new follicles. FDA-approved medications such as minoxidil and finasteride remain the best-proven first-line options.

What About Other Conditions You May Have Heard About?
Some conditions come up often in marketing but are not established stem cell treatments in outpatient clinics. A fair statement for each:
- Autoimmune disease (such as lupus, MS and rheumatoid arthritis): Research is ongoing, but no clinic IV product is proven or approved. See our pages on stem cell therapy for autoimmune conditions and regenerative medicine for autoimmune disease, and talk to your specialist.
- Erectile dysfunction: Interest is high and evidence is early. Read does stem cell therapy really work for ED.
- Stroke, ALS, Alzheimer’s and other neurological diseases: Under study in trials. Our overview of stem cell therapy for stroke recovery and stem cell research for Alzheimer’s covers what is known.
- Autism: Not an established or approved use; see can stem cell therapy help autism symptoms for a careful discussion.
- Cancer: Stem cell transplants are an established treatment for some blood cancers, but that is a different procedure from outpatient injections. Injections do not cure cancer.
The FDA states that none of these products are approved for conditions including orthopedic problems, neurological disorders, autism, heart and lung disease and chronic pain, in its consumer alert on regenerative medicine. It also lists the only approved stem cell products, which are blood-forming cells from umbilical cord blood used for disorders affecting blood production.
What Stem Cell Therapy Does NOT Treat Well
To make good decisions, you also need the “no” list. Stem cell therapy is unlikely to help with:
- Severe, end-stage arthritis where the joint space is gone.
- Large, fully retracted tendon tears that need surgical reattachment.
- Fully collapsed bone from AVN.
- Scarred, bald scalp areas with no follicle activity.
- Conditions caused by an uncontrolled underlying problem, such as poorly controlled diabetes damaging nerves.
- Anything that requires immediate medical or surgical care, such as a fracture, infection or a locked joint.
A responsible clinic tells you when you are not a candidate.
Why Results Differ So Much From One Ailment to the Next
If the nine conditions above seem to have very different levels of evidence, that is not an accident. Several factors decide how well a regenerative treatment can work.
1. How much healthy tissue is left. Stem cell therapy supports tissue that is still alive. A knee with mild to moderate cartilage wear has something to support; a bone-on-bone knee does not. The same logic applies to hair follicles, nerves and tendons.
2. Blood supply. Tissues with a rich blood supply, such as muscle and bone marrow, tend to heal better than tissues with a poor one, such as cartilage, tendon and discs. That is part of why cartilage and tendon research is slower to show clear benefit.
3. Where the cells actually go. A knee injection places cells directly in the joint. A spinal disc injection requires imaging and precision. An IV spreads a product throughout the body, with far less certainty about what reaches the target. Delivery method matters as much as the product itself.
4. How the condition is measured. Pain scores, function questionnaires, MRI findings and nerve conduction tests do not always agree. A trial can show a change on one measure without a change in how a patient feels day to day.
5. The size and quality of the research. Some uses have several randomized trials; others have a handful of small studies with no control group. Honest conclusions follow the data, not the other way around.
6. Patient factors. Age, weight, activity level, other conditions, smoking and how closely you follow rehabilitation instructions all influence outcomes.
Myths vs. Facts About What Stem Cells Can Treat
Myth: “Stem cells can treat almost anything.” Fact: The research supports a limited set of conditions, mostly orthopedic, and even there results vary. Any list that includes dozens of unrelated diseases should raise questions.
Myth: “If it is available in a Miami clinic, it must be FDA-approved.” Fact: None of the nine conditions in this guide has an FDA-approved stem cell treatment. How a clinic can offer a procedure depends on the product, processing and state rules.
Myth: “Stem cells regrow cartilage and bone.” Fact: Laboratory research shows this is possible under controlled conditions, but proof that injections rebuild cartilage or collapsed bone in people is limited.
Myth: “One injection fixes the problem permanently.” Fact: Benefit, when it occurs, can fade over time, and some people need repeat treatment. Underlying causes such as weight, alignment and activity still matter.
Myth: “It is risk-free because it uses your own cells.” Fact: Procedures can cause infection, bleeding or pain, and quality of processing matters. Own-cell products are not automatically safe.
Myth: “Testimonials show it works.” Fact: Individual stories cannot tell you how often a treatment works or whether the improvement came from something else. Controlled studies exist for that reason.
Stem Cells Plus Rehabilitation: Why the Combination Matters
For most of the conditions in this guide, an injection alone is only part of the plan. Cells and growth factors may help create a better environment for healing, but muscles, tendons and joints still need to be loaded in the right way to recover.
- Joints (knee, hip, shoulder): strengthening the muscles around the joint reduces stress on it. Physical therapy is often recommended before and after treatment. See how it fits with back care in combining physical therapy and stem cell therapy for back pain.
- Tendons: progressive loading exercises are a cornerstone of tendon recovery.
- Spine: core strengthening, posture work and activity changes help protect the discs.
- Nerves: blood sugar control, foot care and exercise are essential in diabetic neuropathy.
- Hair: treating thyroid, iron or hormonal issues and using proven medications improves the odds of any hair treatment working.
A clinic that talks only about the injection, and never about rehabilitation or lifestyle, may be selling a quick fix that rarely exists.
Mistakes Patients Commonly Make
1. Choosing the treatment before the diagnosis. Always start with imaging and a clear diagnosis.
2. Expecting a rapid result. Many regenerative effects build over weeks to months. Judge outcomes at the time your provider recommends, not after a few days.
3. Skipping proven first-line care. Physical therapy, weight management and medication often work well, cost less and should not be bypassed.
4. Paying for a large package upfront. Start with a consultation and a plan with defined decision points.
5. Ignoring the fine print on cell source. Ask whether the cells are your own or donor-derived, and how they are processed.
6. Stopping other treatments without advice. Do not stop prescribed medication without your doctor’s approval, especially for diabetes, autoimmune disease or heart conditions.
7. Not tracking results. Note your pain, function and activity before and after, so you can see whether treatment helped.
Practical Tips for Miami Patients
Miami has a large medical community and many regenerative medicine providers, which means options but also noise. A few practical tips:
- Gather your records first. Bring MRI reports, X-rays, medication lists and notes on previous treatments.
- Ask for the evidence for your specific condition. A good provider can discuss studies and their limits.
- Plan follow-up. If you travel to Miami for care, confirm who you can contact after you go home.
- Consider timing. Plan the procedure so you can rest and follow activity limits afterward, especially around travel or a busy season.
- Protect yourself from the heat. After many procedures, hydration and avoiding strenuous activity in extreme heat help recovery.
- Get a second opinion if unsure. A reputable clinic welcomes it.
A Simple Decision Path
If you are trying to decide whether stem cell therapy is worth exploring, this order can help.
- Get a diagnosis with imaging and an exam.
- Try proven conservative care (physical therapy, medication, activity changes) if you have not already.
- Check where your condition falls in the evidence table near the top of this article.
- Book a consultation and ask the questions listed above.
- Decide with a defined plan: what you will do, how you will measure it, and when you will reassess.
- Keep surgery on the table if it is the right option. Trying a regenerative approach first does not usually close the door.
How to Tell Whether It Might Be Right for You
Use these five filters:
- Do I have a clear diagnosis? Imaging and an exam come first, not a sales package.
- Is my condition on the better-supported end? For example, knee osteoarthritis and early AVN have more research than, say, hair loss or neuropathy.
- Have I tried proven options? Physical therapy, medication, weight management and bracing are often first.
- Do I understand the evidence? Ask for studies, not testimonials.
- Can I afford it if it does not work? Insurance usually does not cover investigational treatment. See are stem cell injections covered by insurance and insurance coverage for stem cell injections in Miami.
What a Typical Visit Looks Like
While details vary by condition, most outpatient regenerative visits follow a similar pattern:
- Consultation and imaging review. Your history, goals and prior treatments are discussed.
- Candidacy decision. A good provider will say if you are or are not a candidate.
- Cell collection (if using your own cells), such as a bone marrow draw or fat harvest, using local anesthesia.
- Processing. Cells are concentrated, usually in about 15 to 30 minutes.
- Image-guided delivery. The product is injected into the target area, often with ultrasound or fluoroscopy.
- Aftercare and follow-up. You receive activity guidance and a plan to measure results.

Risks and Side Effects
Most outpatient regenerative treatments have mild, short-term side effects, but they are not risk-free. Possible issues include:
- Soreness, bruising or swelling at the collection and injection sites
- Temporary flare of pain after the injection
- Infection (rare)
- Bleeding
- Allergic or immune reactions with donor-derived products
- Procedure-specific risks (the spine, in particular, requires skill)
- No benefit at all
The disc disease meta-analysis above is a good reminder that safety signals can appear in controlled trials, so ask your provider how they handle complications. For more, see is stem cell therapy safe for joint regeneration, possible side effects like swelling, pain or infection and downsides to consider.
Is Stem Cell Therapy FDA-Approved for These Ailments?
No. None of the nine conditions above has an FDA-approved stem cell treatment. The FDA’s position is that, generally, stem cell products require FDA approval, and it has warned consumers about unapproved products. How a clinic can lawfully offer a procedure depends on the product, how it is processed and how it is used, and state law adds another layer. Our explainers on FDA-approved stem cell treatments and the state’s orthopedic MSC approval cover what that means in practice.
Practical rule: a clinic being allowed to offer a treatment is not proof that it works. Ask which product is used, where it comes from and what the regulatory pathway is.
Cost of Stem Cell Therapy in Miami
Cost depends on the condition, the product and the number of treatments. Because these treatments are generally not covered by insurance, plan to pay out of pocket and ask for a written, itemized quote that includes follow-up. Our pages on the average cost of stem cell therapy, stem cell therapy costs in Miami and the economics of stem cell therapy explain what drives pricing.
If you are comparing value, ask what a realistic outcome looks like, how you will measure it, and what you will do if you do not respond. Our guide on how to choose a stem cell therapy treatment center can help you compare providers.

Frequently Asked Questions
What conditions can stem cell therapy treat?
In regenerative clinics it is most often used for orthopedic conditions such as knee osteoarthritis, with early research for tendon, disc, nerve and hair conditions. None of these uses is FDA-approved.
Can stem cell therapy cure arthritis?
No. It may reduce pain and improve function for some people with mild to moderate arthritis, but it does not reverse the disease and results vary.
Which condition has the best evidence for stem cell therapy?
Knee osteoarthritis and early-stage avascular necrosis (combined with surgery) have the most research, though even there the evidence has limits and findings are mixed.
Does stem cell therapy work for back pain?
Some studies show reduced pain and disability in degenerative disc disease, but a meta-analysis also found more treatment-related adverse events in the stem cell group. It is not a guaranteed fix.
Can stem cells help neuropathy?
Small trials suggest improvements in nerve conduction and symptom scores in diabetic neuropathy, but the evidence is early.
Can stem cell therapy regrow hair?
It may help some people with early pattern thinning, but it cannot restore hair to completely bald areas and is not FDA-approved.
Is stem cell therapy covered by insurance?
Usually no, because it is considered investigational. Confirm with your insurer.
How long do results last?
It depends on the condition and the person. Some people report benefit for months to a year or more, and others see little change. See how long stem cell injections last.
Is stem cell therapy safe?
Short-term side effects are usually mild, but risks include infection, reactions and no benefit. Long-term safety data are limited.
Can stem cell therapy treat cancer, autism or Alzheimer’s?
No injection-based clinic treatment has been proven for these. Stem cell transplants for certain blood cancers are a different, hospital-based medical procedure.
Should I try stem cells before surgery?
It depends on your condition, stage and goals. Many people try conservative and regenerative options first, and surgery remains available later.
How do I know if I am a candidate?
A consultation with imaging and a clear diagnosis is the best way to find out. A good provider will tell you honestly if it is not right for you.
Bottom Line
The honest answer to “what can stem cell therapy treat?” is: a handful of conditions, modestly, with variable results, and none with FDA approval. Knee osteoarthritis and early avascular necrosis have the most research behind them. Back, tendon, nerve and hair conditions have promising but early evidence. For everything else, be skeptical of bold promises.
