This has been happening in the PRP world for the last half-decade or more, but it is also about to happen in the world of bone marrow, adipose stromal vascular fraction, and umbilical cord stem cells. Another entry in this new study class was published just this past month, and its results are unexpected and confusing. So, let\u2019s dive into it today and try to learn as much as possible.<\/p>\n<h2>What Are the Different Orthobiologics We Will Be Discussing?<\/h2>\n<p>The orthobiologics tested in this study include BMC or Bone Marrow Concentrate, SVF or Stromal Vascular Fraction, and Culture Expanded Umbilical Cord MSCs. Let\u2019s go through each one:<\/p>\n<ul>\n<li><strong>Bone Marrow Concentrate (aka BMAC)<\/strong>: This is made by taking bone marrow aspirate and concentrating the cell-containing fraction in a centrifuge. This is permitted by the US FDA right now.<\/li>\n<li><strong>SVF (Stromal Vascular Fraction):<\/strong> Adipose tissue is taken by liposuction and then digested using an enzyme to access the cells, which are then centrifuged. This is a drug that requires FDA approval.<\/li>\n<li><strong>Culture Expanded Umbilical Cord MSCs<\/strong>\u2013 This biologic is created by harvesting umbilical cord Wharton\u2019s Jelly, digesting it with an enzyme, centrifuging, and then placing it in culture to isolate and grow more mesenchymal stem cells. This is another drug requiring FDA approval.<\/li>\n<\/ul>\n<p>In this study, a corticosteroid injection was also used. This is the standard anti-inflammatory injection given in doctor\u2019s offices worldwide. This is a mega dose of steroid, usually about 100,000-1,000,000 times the dose that your body would use on a day-to-day basis.<\/p>\n<div class=\"blog-cta-container lazy\" data-src=\"https:\/\/regenexx.com\/wp-content\/uploads\/2022\/07\/streets-10.jpg\">\n<p>Find a Regenexx Location Near You<\/p>\n<p>97 clinic locations offering non-surgical Regenexx solutions for musculoskeletal pain.<\/p>\n<p>97 clinic locations offering non-surgical Regenexx solutions for musculoskeletal pain.<\/p>\n<p><a rel=\"noopener\" target=\"_blank\" href=\"https:\/\/regenexx.com\/locations\/\" class=\"teek-button teek-button-raised teek-button-lime\">Find a Location<\/a><\/div>\n<h2>The Money Shot<\/h2>\n<p>Most studies have one or two graphs that tell you in a simple way what the authors found, and this one is no different:<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/platohealth.ai\/wp-content\/uploads\/2023\/11\/new-study-of-many-cell-therapies-versus-steroid-yields-interesting-results-regenexx-1.png\" height=\"2256\" width=\"5410\" class=\"aligncenter size-full wp-image-94190 sp-no-webp\" alt> <\/p>\n<p>Here, we see the four interventions graphed on a functional scale (KOOS) where more is better. What can we see? The two interventions that seem to have done the best at all of the time points up to one year are the BMAC and the steroid. The intervention that appears to have done the worst at all time points up to one year is the expanded umbilical cord stem cells. For all months after the first, the SVF falls between those two (BMAC\/Steroid and SVF). It should be noted that none of these differences were statistically different at any time point. Hence, it\u2019s better to call these \u201ctrends\u201d and not differences.<\/p>\n<h2>The First Unusual Finding of This Study<\/h2>\n<p>In this study, a corticosteroid shot worked very well for a year. That\u2019s a little atypical, depending on the severity of the arthritis. For example, based on my clinical experience, a steroid shot can last a long time in moderate arthritis, but in severe knee arthritis, it usually provides shorter-lasting relief.<\/p>\n<p>Based on high-level RCTs, do corticosteroids work to treat knee arthritis pain? The most extensive and most accomplished study was done in 2017 and published in the New England Journal of Medicine. It showed that at <strong>two years<\/strong>, there was no difference between a steroid shot and saline (2). It also showed that the steroid shot damaged knee cartilage over those two years, eroding about double the cartilage that normal wear and tear accomplished over that period. <strong>Realize that the two-year results of this study have yet to be published.<\/strong><\/p>\n<h2>More Steroid Side Effects<\/h2>\n<p>There\u2019s a reason the doctors who have adopted orthobiologics have ditched steroid injections, even beyond the fact that they destroy joint cartilage:<\/p>\n<ul>\n<li>A knee steroid shot increases the likelihood of a subsequent knee replacement failure or infection (11).<\/li>\n<li>A steroid injection also has systemic side effects like decreasing bone density,&nbsp; disrupting your cortisol endocrine system, and spiking your blood sugar (12-14).<\/li>\n<\/ul>\n<p><a rel=\"noopener\" target=\"_blank\" href=\"https:\/\/regenexx.com\/resources\/webinars\/?id=m1g0xb2\" data-webinarhash=\"m1g0xb2\" data-post=\"94187\" class><span>Join us for a free Regenexx webinar.<\/span><\/a><\/p>\n<h2>Orthobiologics vs Steroid<\/h2>\n<p>What can we learn about the new study by comparing it to other RCTs that have tested orthobiologics against a steroid shot? Maybe quite a bit.<\/p>\n<p>Platelet-rich plasma has been tested in at least a half dozen randomized controlled trials against steroids (3-8). In general, the graphs from three of these positive studies are emblematic of what\u2019s usually seen:<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/platohealth.ai\/wp-content\/uploads\/2023\/11\/new-study-of-many-cell-therapies-versus-steroid-yields-interesting-results-regenexx-2.png\" height=\"2346\" width=\"4077\" class=\"aligncenter size-full wp-image-94191 sp-no-webp\" alt> <\/p>\n<p>If you look above, you can see that as time goes on, there is a separation between the steroid and the PRP, with the PRP performing better.<\/p>\n<p>This is how these six studies turned out:<\/p>\n<ul>\n<li>Three studies showed that PRP was superior compared to steroids (3, 5, 6). <strong>All three studies exceeded the minimum 2X PRP definition.<\/strong><\/li>\n<li>One study showed that a steroid injection before a PRP injection seemed to work better (4).<\/li>\n<li>One study showed that \u201cPRP\u201d was non-inferior to steroids, but <strong>that study didn\u2019t meet the 2X PRP threshold<\/strong> (8).<\/li>\n<li>One study showed that \u201cPRP\u201d was no better than saline placebo (<strong>regrettably, this study also never used a product that met the minimum 2X definition for PRP<\/strong>) (7).<\/li>\n<\/ul>\n<h2>Who Was Treated in Each Group?<\/h2>\n<p>The first critical piece of information we need to interpret a study like this is how old these patients were and how severe the arthritis was in these groups. First on age, here\u2019s the breakdown of the under and over 60 for the whole study:<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/platohealth.ai\/wp-content\/uploads\/2023\/11\/new-study-of-many-cell-therapies-versus-steroid-yields-interesting-results-regenexx-3.png\" height=\"260\" width=\"390\" class=\"aligncenter wp-image-94193 sp-no-webp\" alt loading=\"lazy\"> <\/p>\n<p>So, this is a primarily elderly group with a younger mean age of 58.<\/p>\n<p>How did the distribution of moderate and severe arthritis look in each group? Meaning, was this an identical distribution?<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/platohealth.ai\/wp-content\/uploads\/2023\/11\/new-study-of-many-cell-therapies-versus-steroid-yields-interesting-results-regenexx-4.png\" height=\"476\" width=\"714\" class=\"aligncenter wp-image-94195 sp-no-webp\" alt loading=\"lazy\"> <\/p>\n<p>To understand the graph above, you need to know that the Kellgren-Lawrence (KL) Grading scale is from 0-4. KL2 is moderate arthritis, KL3 is moderate-severe, and KL4 is severe.<\/p>\n<p>The BMAC group had the highest proportion of severe arthritis cases (KL4). The UCT group had the highest proportion of moderate arthritis. The steroid group had a low proportion of severe cases.<\/p>\n<p>We can see this discrepancy better if we compare the severe KL4 cases to the more moderate KL2\/KL3 cases:<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/platohealth.ai\/wp-content\/uploads\/2023\/11\/new-study-of-many-cell-therapies-versus-steroid-yields-interesting-results-regenexx-5.png\" height=\"507\" width=\"761\" class=\"aligncenter wp-image-94196 sp-no-webp\" alt loading=\"lazy\"> <\/p>\n<p>The BMC group looks quite different here, with a much higher proportion of severe versus moderate cases. Again, the steroid group has the most significant proportion of moderate versus severe cases. To understand that divide, the proportion of moderate to severe cases in the BMAC group is 1.7, while that same proportion in the steroid group is a whopping 2.75!<\/p>\n<p>This may help explain why this study\u2019s steroid shots lasted so long. There were almost three moderate knee arthritis cases in that group for every severe case.<\/p>\n<h2>Umbilical Cord MSCs Better?<\/h2>\n<p>One of the interesting things to note here is that the \u201cyoung\u201d umbilical cord cells didn\u2019t beat the autologous bone marrow and fat therapies. That\u2019s likely because these cells were allogeneic (from a donor). <a rel=\"noopener\" target=\"_blank\" href=\"https:\/\/regenexx.com\/blog\/necrobiology-fake-umbilical-cord-stem-cell-products-and-clinical-efficacy\/\">I have often reported on research showing that allogeneic stem cells are not invisible to the host\u2019s immune system.<\/a> They are detected and eliminated.<\/p>\n<h2>What Does Year Two Hold?<\/h2>\n<p>At this point, we don\u2019t know what year 2 of this study tells us. First, it\u2019s improbable that the steroid, given the New England Journal paper reviewed above, will still produce great results by 24 months, but with a less severe arthritis group, who knows? It\u2019s also probable that some of these cell therapies will begin to separate themselves from the massive steroid anti-inflammatory and, ultimately, catabolic effect.<\/p>\n<h2>Inadequate BMC Treatment?<\/h2>\n<p>One of the differences between what\u2019s done in this study and what\u2019s now more commonly done in advanced orthobiologics practices is the use of intraosseous injections. Since Hernigou\u2019s RCTs were published, showing the superiority of IO (Intraosseous) over intra-articular injections alone, many high-level clinics have made the switch (9,10). This study didn\u2019t use the IO+IA treatment.<\/p>\n<p>In addition, we\u2019ve been treating ligamentous laxity in knee OA cases for over a decade. Many of these patients have a lax MCL, LCL, or ACL that needs to be targeted to maximize results. These are classified as \u201cdegenerative instability\u201d and are not surgical issues, but in my clinical experience, treating these areas makes a big difference in the final outcome. This was not done in this study.<\/p>\n<p>We also have no idea how good or bad the bone marrow aspirates were in this study. A good harvest technique is described, but only 60 ml was taken, which is low by today\u2019s knee OA treatment standards. For example, the current Regenexx knee OA protocol for knee IA+IO is a 120 ml draw. The authors have promised to publish that data eventually.<\/p>\n<h2>To Review the Issues<\/h2>\n<p>As the authors of this study admit, there is no perfect study. Here are the issues I can find:<\/p>\n<ol>\n<li>No placebo control-These cell based treatments are compared to a known treatment. That\u2019s not a critical error, as this is still valuable data.<\/li>\n<li>Steroids can be very effective in treating the inflammation generated by knee arthritis, but they destroy the joint, increase the likelihood of knee replacement infection and failure, and have adverse systemic side effects.<\/li>\n<li>The robust steroid results don\u2019t agree with several other RCTs performed on PRP. That could be because there were far more moderate and fewer severe OA cases in the steroid group.<\/li>\n<li>There is a much higher proportion of severe arthritis cases in the BMC group than in the steroid control group!<\/li>\n<li>The culture-expanded Umbilical Cord group didn\u2019t perform better, likely due to a seminal and unavoidable donor rejection problem with allogeneic cell products.<\/li>\n<li>The study tested an older and less effective IA BMC treatment, not the gold standard IA+IO used in 2023. It also neglected to address degenerative ligamentous instability.<\/li>\n<\/ol>\n<p>The upshot? Interesting study, and I am thankful for all of the hard work put in by the authors, including Ken Mautner of Emory and his team. I look forward to more of this dataset getting published! In the meantime, I\u2019m not sure it changes much for us.<\/p>\n<p>____________________________________________<\/p>\n<p>References:<\/p>\n<p>(1) Mautner, K., Gottschalk, M., Boden, S.
