PRP therapy uses a concentration of platelets prepared from your own blood, while treatments marketed as stem cell therapy may involve cells or tissues obtained from bone marrow, fat, birth tissue, or another source.
Which option may be appropriate for joint pain depends on your diagnosis, the severity of the joint damage, your health history, previous treatments, and the exact product being offered.
At Allcare Medical & Injury in Orlando, we begin with an evaluation to understand the cause of your pain before discussing treatment options.
Neither treatment is automatically the right choice for every patient. Results vary, and these injections should not be presented as guaranteed replacements for physical rehabilitation, medication, or surgery.
PRP and Stem Cell Therapy Compared
How PRP Therapy Is Prepared
Platelet-rich plasma, or PRP, begins with a blood draw. The sample is placed in a centrifuge to separate and concentrate certain blood components. The resulting platelet-rich portion is then injected into the targeted area.
Platelets are involved in the body’s normal response to injury and contain proteins known as growth factors. The rationale behind PRP is to place a concentrated preparation of these components near an injured or painful area.
However, PRP systems and preparation methods vary, and research findings are not identical for every condition or joint.
Because PRP is prepared from the patient’s own blood, the risk of an allergic reaction to donated tissue is reduced. Injection-related risks can still include pain, bleeding, bruising, infection, or irritation of nearby structures.

What “Stem Cell Therapy” Can Mean
The phrase “stem cell therapy” is used broadly in consumer marketing, but it does not describe one standardized treatment. Products may be derived from a patient’s bone marrow or fat, or from donated birth-related tissue such as umbilical cord tissue. These products are not interchangeable.
Allcare Medical & Injury discusses human cellular tissue derived from donated umbilical cord tissue as part of its regenerative medicine services. Patients should ask for the precise name, source, ingredients, processing method, and regulatory status of any product under consideration.
It is also important not to assume that every birth-tissue product contains living stem cells or has been shown to regenerate cartilage. Claims should be evaluated based on the exact product and reliable clinical evidence—not the category name alone.
You can review the treatment described by our Orlando clinic on our human cellular tissue page.
Important FDA Information About Cell-Based Treatments
The U.S. Food and Drug Administration regulates human cell and tissue products. According to the FDA, regenerative medicine therapies have not been approved to treat orthopedic conditions such as osteoarthritis, tendonitis, disc disease, back pain, knee pain, hip pain, neck pain, or shoulder pain.
The FDA states that the only stem cell products currently approved in the United States are certain blood-forming stem cells derived from umbilical cord blood for disorders affecting blood production—not orthopedic joint pain.
This does not mean every procedure described as regenerative medicine is regulated in exactly the same way. It does mean patients should carefully investigate the specific product and claims being made.
Before proceeding with a cell- or tissue-based injection, ask:
- What is the exact name of the product?
- Is it made from my tissue or donated tissue?
- Does it contain living cells, and how has that been verified?
- Is it FDA-approved for treating my specific joint condition?
- If it is investigational, is treatment occurring in an FDA-authorized clinical trial?
- What published evidence supports this product for my diagnosis?
- What side effects or complications have been reported?
- What alternatives should I consider?
Patients can read the FDA’s information about regenerative medicine therapies before making a decision.
When PRP May Be Considered for Joint Pain
PRP may be discussed when joint pain has not improved adequately with initial conservative measures. The decision depends on the diagnosed condition rather than pain alone.
A clinician may consider factors such as:
- The joint involved
- The severity and duration of symptoms
- Imaging and physical examination findings
- Whether the problem involves cartilage, a tendon, or a ligament
- Previous responses to rehabilitation or other treatment
- Medications and conditions that affect blood or healing
- The patient’s goals and activity level
PRP is not expected to restore a severely damaged joint to its original condition. Patients should receive a realistic explanation of potential benefits, limitations, cost, and recovery before deciding.
When a Cell- or Tissue-Based Treatment May Be Discussed
A cell- or tissue-based product may be presented to patients with chronic joint pain or degenerative changes who are exploring non-surgical options. However, “more advanced” does not necessarily mean better supported for a particular diagnosis.
The decision requires careful review because products differ substantially. Patients should understand whether a proposed injection is an approved treatment, an investigational product administered through a clinical trial, or a human cell or tissue product being offered under another regulatory pathway.
At Allcare Medical & Injury, we believe patients should have enough information to make an informed decision. A consultation should include the product identity, proposed purpose, known risks, reasonable alternatives, and the limits of available evidence.
How Your Diagnosis Affects the Choice
“Joint pain” is a symptom rather than one specific condition. Knee pain may result from osteoarthritis, a meniscus injury, tendon irritation, instability, referred pain, or another problem. Shoulder pain may involve the rotator cuff, bursa, joint cartilage, neck, or several structures at once.
An evaluation may include:
- A detailed medical and injury history
- A physical examination
- Assessment of strength and range of motion
- Review of previous imaging and treatments
- Additional diagnostic testing when indicated
The findings may show that PRP should be considered, that another treatment is more appropriate, or that an orthopedic evaluation is needed. Some patients may benefit from rehabilitation alone or from a plan combining multiple forms of care.
PRP and Other Treatments May Work Together
An injection does not correct every factor contributing to joint pain. Muscle weakness, limited mobility, poor movement patterns, excess joint loading, and an unresolved injury can continue to affect the area.
A broader plan may include:
- Activity modification during recovery
- Physical rehabilitation
- Strength and mobility exercises
- Weight-management support when relevant
- Changes to training or workplace demands
- Referral for orthopedic care when appropriate
Our regenerative medicine services in Orlando are considered within the context of the patient’s overall condition and treatment goals.
Questions to Ask During Your Consultation
Whether you are considering PRP or a product marketed as stem cell therapy, ask direct questions before agreeing to treatment:
- What is my specific diagnosis?
- Why is this treatment being recommended for me?
- What evidence applies to my condition?
- What outcome is realistic?
- How many injections are proposed?
- What should I expect during recovery?
- What are the risks and potential complications?
- Will I also need rehabilitation?
- What happens if the treatment does not help?
- What other options are available?
Which Joint Pain Treatment Is Right for You?
PRP may be considered when a patient and clinician want to use an autologous blood-derived preparation for an appropriately evaluated musculoskeletal condition. A cell- or tissue-based treatment requires additional scrutiny because the source, contents, evidence, risks, and regulatory status can vary widely.
Neither choice should be made from a website description alone. At Allcare Medical & Injury in Orlando, we evaluate your joint, review your health history, and discuss suitable treatment options so you can make a more informed decision.
If joint pain is limiting your mobility in Orlando, call us today at 407-807-6645 to schedule a consultation and discuss whether PRP or another treatment may be appropriate for you.
