How to Prepare for Stem Cell Therapy for Knee Osteoarthritis

Preparing for stem cell therapy for knee osteoarthritis involves five core steps: confirming you are actually a reasonable candidate, reviewing every medication and supplement with your prescribing doctors, adjusting activity levels in the days before treatment, planning the logistics of the procedure itself, and calibrating your expectations against the current evidence. Before going further, one fact needs to be stated plainly: The U.S. FDA has not approved stem cell or other regenerative therapies for knee osteoarthritis, , but Mexico’s equivalent, COFEPRIS has approved stem cell therapy use and Dream Body Clinic is in Mexico. This doesn’t mean the therapy lacks value — many patients report meaningful improvement — but it does mean preparation should be approached with the same scrutiny you’d apply to any medical decision. This guide walks through each preparation step in detail, citing primary sources along the way.

Confirm Your Candidacy First

Before anything else, you need a clear, evidence-based answer to whether your knee is actually a good candidate for cell-based treatment. This is not a step to skip or self-diagnose.

Imaging and Diagnostic Criteria

Most reputable evaluations begin with an MRI to assess cartilage thickness, joint space narrowing, and bone changes. Clinicians commonly use the Kellgren-Lawrence (KL) grading scale, which classifies osteoarthritis severity from Grade 0 (no changes) to Grade 4 (severe, bone-on-bone disease). Research published in orthopedic journals has generally found that patients with mild-to-moderate osteoarthritis (roughly KL Grade 1–3) tend to report better outcomes from orthobiologic injections than those with advanced, bone-on-bone disease.

When Stem Cell Therapy May Not Be Appropriate

Certain conditions typically rule out — or at least significantly complicate — candidacy, including:

• End-stage, bone-on-bone osteoarthritis (often better served by joint replacement)
• Active local or systemic infection
• Large Osteophytes (bone spurs)
• Certain active cancers or blood disorders affecting cell collection or immune response
• Uncontrolled bleeding disorders

There is no single universal eligibility checklist used across all clinics worldwide, which is exactly why a thorough, individualized evaluation — imaging, medical history, and a frank conversation about your specific knee — matters more than any generic online quiz. Clinics such as Dream Body Clinic in Puerto Vallarta, Mexico, which treats knee osteoarthritis as its flagship orthopedic service, build their intake process around this kind of individualized review of imaging and health history rather than offering treatment to anyone who requests it. That candidacy-first approach is a reasonable benchmark to look for in any clinic you’re considering.

Medications and Supplements to Discuss With Your Care Team

This is arguably the single highest-risk preparation step, and it deserves the most careful attention.

NSAIDs and Blood Thinners

Many clinical protocols for orthobiologic injections call for pausing nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen and naproxen in the days before and after treatment, since these medications can theoretically blunt the inflammatory signaling that some researchers believe contributes to healing response. However, aspirin and prescription anticoagulants (such as warfarin or DOACs) are a different matter entirely — these are often prescribed for serious cardiovascular or clotting-related reasons, and stopping them without explicit approval from the prescribing physician can be dangerous. Never discontinue a blood thinner on your own initiative, even if a clinic’s general pre-procedure instructions mention it.

Supplements That Affect Bleeding or Inflammation

Several common over-the-counter supplements can also affect bleeding risk or inflammatory pathways and should be flagged for discussion — not automatically stopped — with your care team:

• Gingko Biloba
• Turmeric or curcumin extracts
• Garlic extract supplements

Why You Should Never Stop Medication Without Prescriber Approval

Good preparation requires coordination between the clinic performing the injection and every physician managing your existing conditions — for example, a cardiologist overseeing anticoagulation therapy or a rheumatologist managing an autoimmune condition. A reputable clinic should ask for a full medication list and, when appropriate, request clearance documentation rather than simply handing you a generic pre-procedure sheet. If a clinic doesn’t ask detailed questions about your medications, that’s a signal to ask more of them yourself.

Adjusting Your Knee and Exercise Routine Before Treatment

Activity Modification in the Days Before Treatment

General guidance across most clinical protocols favors reducing high-impact loading on the affected knee — running, jumping, heavy squatting, or long periods of standing — in the days leading up to treatment. Exact timelines vary by clinic and by the severity of the underlying arthritis, so this should always be confirmed with your treating physician rather than assumed from a generic online schedule.

Weight-Bearing and Joint Protection Tips

In the lead-up to treatment, reasonable steps include:

• Continuing gentle range-of-motion exercises rather than starting anything new or strenuous
• Avoiding sudden increases in activity intensity, even if the knee feels “good that day”
• Prioritizing sleep quality and adequate hydration in the days beforehand
• Using any prescribed bracing or assistive devices as directed, rather than discontinuing them preemptively

Again, the operative principle is to follow your treating clinic’s specific instructions. Protocols differ based on cell source, injection technique, and the severity of your osteoarthritis, so a one-size-fits-all exercise taper found online may not match what your actual treatment plan requires.

Understanding the Evidence and Setting Realistic Expectations

What Current Research Shows (and Doesn’t)

Systematic reviews and clinical trials registered on platforms like ClinicalTrials.gov generally point to a consistent pattern: several studies report improvements in pain and function following mesenchymal stem cell or bone marrow aspirate concentrate injections for knee osteoarthritis, but the overall certainty of evidence remains low to moderate due to small sample sizes, variable cell preparation methods, and limited long-term follow-up. 

In the USA they have a rule called minimal manipulation. This means they can’t fully isolate and culture stem cells for treatments. So patients can get minimally manipulated stem cells from fat, bone marrow or umbilical cord tissue, but only a small percentage of what they are calling stem cells is actually stem cells. It is mostly other types of cells due to the minimal manipulation.

      There are a lot of studies on MSCs for knee repair, but even with all the evidence the hesitate to state that it really works. This is because even with over 100,000 studies done on mesenchymal stem cells (you can verify on google scholar), the FDA system gets in the way of approval. To get mesenchymal stem cells approved for knee repair each type of treatment requires a $2.5 million USD application feel. So knee osteoarthritis would be $2.5 million then meniscus repair would be $2.5 million and so on. That application fee just gets the clinic into the 4 phase FDA trials. Those typically take over 7 years and cost hundreds of millions of dollars to complete. Then at the end you can’t patent a mesenchymal stem cell so you would just be opening the market to your competition. You would spend hundreds of millions of dollars for each different type of treatment and would not be able to recover your costs. It is a flawed system designed to protect big pharmaceutical companies and keep people hooked on pills or resort to surgery.

Questions to Ask Your Treating Clinician

Cell Source and Preparation

Ask specifically whether cells will come from your own bone marrow aspirate, adipose (fat) tissue, or another source, and how those cells are processed before injection. Processing methods differ meaningfully in cell concentration and preparation time, and a transparent clinic should explain this clearly. 

At Dream Body Clinic we use Wharton Jelly (umbilical cord tissue) and placenta. This is because these tissues offer very young mesenchymal stem cells that can help you heal like when you were a kid. The lab page explains this in much more depth – https://dreambody.clinic/certified-stem-cells/

Number of Injections and Follow-Up

Clarify how many injections are included in your treatment plan, whether booster sessions are anticipated, and what the follow-up monitoring schedule looks like — including imaging or functional assessments at specific intervals.

Cost, Credentials, and Safety Track Record

Finally, ask about:

• The treating physician’s specific training and experience with orthobiologic procedures
• Facility accreditation or licensing documentation – all listed here for dream body clinic
• Transparent, itemized pricing with no hidden fees – $3,500 usd per knee at DBC

A clinic willing to answer all of these questions directly is generally a better sign than one that isn’t.

Logistics and Day-of Preparation

For patients traveling for treatment, whether domestically or internationally, logistics deserve as much planning as the medical side. Arrange transportation to and from the clinic in advance, since you may have temporary mobility restrictions afterward. Confirm fasting requirements or other same-day instructions directly with the clinic, since these vary depending on whether sedation is used. Bring comfortable, loose-fitting clothing that allows easy access to the knee, and pack any mobility aids you may need for the days following the procedure. Patients traveling abroad for treatment should specifically request documentation of clinic licensing, physician credentials, and safety protocols before booking — this is a reasonable, non-confrontational request that any legitimate clinic should be able to fulfill quickly. – all listed here for dream body clinic

What to Expect After Treatment

Recovery timelines vary by clinic protocol and individual response, but most patients are advised to limit high-impact activity for a defined period afterward, use ice or anti-inflammatory measures sparingly (per clinic instructions), and gradually reintroduce normal movement under guidance. Contact your clinic promptly if you experience signs of infection, significant swelling, or pain that worsens rather than improves. Because rehabilitation protocols differ across providers, follow the specific plan your treating clinic provides rather than a generic timeline found online.

Conclusion

Good preparation for stem cell therapy for knee osteoarthritis isn’t primarily about packing the right clothes or doing a few extra stretches — it’s about informed decision-making. That means confirming genuine candidacy through proper imaging and evaluation, coordinating medication and supplement changes carefully with every prescribing physician, adjusting activity sensibly in the days beforehand, and understanding what the current evidence can and cannot promise. Choose clinics that prioritize transparency about cell source, protocol, credentials, and limitations over clinics that lead with bold promises. Asking direct questions and expecting clear, documented answers is the most reliable form of preparation you can do.
