A systematic review of 32 studies comparing leukocyte-poor and leukocyte-rich PRP in knee OA found both formulations improved pain and function above the MCID with no significant difference between them at 3, 6 or 12 months - but leukocyte-RICH PRP carried significantly higher odds of post-injection pain (OR 1.64; 95% CI 1.29-2.10) and swelling (OR 1.56; 95% CI 1.22-1.99). Kim JH, et al. — [Adverse Reactions and Clinical Outcomes for Leukocyte-Poor Versus Leukocyte-Rich Platelet-Rich Plasma in Knee Osteoarthritis: A Systematic Review and Meta-analysis.](https://pubmed.ncbi.nlm.nih.gov/34277879/). *Orthopaedic Journal of Sports Medicine*, 2021. DOI: 10.1177/23259671211011948. 2. A double-blind randomized trial allocated 192 patients with KL 1-3 knee OA to three weekly injections of leukocyte-RICH or leukocyte-POOR PRP (mean leukocyte concentration 7,991 x10^6/L vs 0.1 x10^6/L). No difference was found in any clinical score at 2, 6 or 12 months (IKDC improved 45.6 to 60.7 vs 46.8 to 62.9; P=.626). Mild adverse events were numerically more frequent with leukocyte-rich PRP (12.2% vs 4.7%) but not significantly so.

DOI: 10.1177/03635465211064303. 3. A meta-analysis of 6 RCTs (860 patients, 334 receiving BMAC) found overall complication rates of 41.91% for BMAC versus 41.25% for comparator injectables (P=0.85), with knee effusion the commonest BMAC complication at 18.26%. Early and late complication rates did not differ significantly from HA, steroids, PRP, SVF, MSC or saline. The number needed to harm for BMAC relative to other injections was 152.

DOI: 10.1016/j.jor.2024.10.005. 4. The BMJ meta-analysis of viscosupplementation pooled 169 trials (21,163 participants) and found clear evidence of small-study effects and publication bias. In the prespecified main analysis of 24 LARGE placebo-controlled trials (8,997 participants) hyaluronic acid reduced pain by SMD -0.08 (95% CI -0.15 to -0.02), equivalent to 2.0 mm on a 100 mm scale - far below the -0.37 minimal important difference - and trial sequential analysis showed there has been CONCLUSIVE evidence of clinical equivalence to placebo since 2009. Fifteen large trials showed a significantly higher risk of serious adverse events (RR 1.49).

The 2025 Cochrane review of stem cell injections for knee osteoarthritis pooled 25 randomised trials (1,341 participants) and found that, compared with placebo injection, stem cell injection MAY slightly improve pain (1.2 points better on a 0-10 scale, 7 studies, 445 participants) and function (14.2 points better on a 0-100 scale, 7 studies, 432 participants) up to six months - both rated LOW-certainty evidence, downgraded for indirectness (cell source, preparation and dose varied across studies) and suspected publication bias, since up to three larger RCTs were conducted and withdrawn before reporting results. Radiographic progression was not assessed in any included study. Whittle SL, et al. — [Stem cell injections for osteoarthritis of the knee.](https://pubmed.ncbi.nlm.nih.gov/40169165/). *Cochrane Database of Systematic Reviews*, 2025. DOI: 10.1002/14651858.CD013342.pub2. 6. FDA states verbatim of stem cell products, stromal vascular fraction (adipose-derived cells), umbilical cord blood, Wharton's jelly, amniotic fluid and exosome products: 'None of these products have been approved for the treatment of any orthopedic condition, such as osteoarthritis, tendonitis, disc disease, tennis elbow, back pain, hip pain, knee pain, neck pain, or shoulder pain.' The only FDA-approved stem cell products in the United States are blood-forming (hematopoietic progenitor) cells derived from umbilical cord blood, approved only for disorders of blood production, and there are currently NO FDA-approved exosome products. U.S. Food and Drug Administration — [Consumer Alert on Regenerative Medicine Products Including Stem Cells and Exosomes](https://www.fda.gov/vaccines-blood-biologics/consumers-biologics/consumer-alert-regenerative-medicine-products-including-stem-cells-and-exosomes). *FDA (Center for Biologics Evaluation and Research)*, 2020. 7. FDA's patient and consumer notice on regenerative medicine states that it has received reports of BLINDNESS, TUMOUR FORMATION, neurological events, bacterial infections including life-threatening blood infections, unwanted immune reactions, and cells migrating and forming unintended tissue, following the use of unapproved regenerative medicine products - a list that explicitly includes stromal vascular fraction, amniotic fluid, Wharton's jelly, ortho-biologics and exosomes. It also warns that a product's presence on clinicaltrials.gov, or a firm's registration with FDA, does NOT mean the product is legally marketed.

Medicare's national coverage determination states that CMS covers autologous platelet-rich plasma ONLY for patients with chronic non-healing diabetic, pressure and/or venous wounds, and only inside an approved coverage-with-evidence-development clinical study. Every approved study listed under the NCD is a wound-healing study. There is no Medicare national coverage for PRP in osteoarthritis or tendinopathy, which is why these injections are billed to the patient.

The AAOS patient-education FAQ on orthobiologics states that because orthobiologics are relatively new the evidence supporting their use is LIMITED, that rigorous testing of effectiveness in most orthopedic conditions is lacking, and that preliminary results are encouraging but hard to evaluate. It names tendinopathies such as tennis elbow, pain from early knee osteoarthritis, adjunct healing after rotator cuff repair, and avascular necrosis as the settings where biologic therapies have shown promise, and notes that stem cell treatments not derived from the patient's own body and further manipulated in a laboratory can only be offered inside an FDA-approved clinical trial.

PRP stands for platelet-rich plasma. Staff spin your blood to gather platelets, then put the prepared blood into your aching joint. The joint may briefly feel sore or swollen afterward. Cost matters too, and no one can promise your result. ## How sore is the place where marrow is taken for BMAC? BMAC means bone marrow aspirate concentrate. Staff take marrow from your pelvis, spin it, and put the concentrate into the aching joint. The spot on your pelvis and the joint may both feel tender. Ask about driving, bathing, sleep, and heavier work. ## How soon can I stand or walk after PRP? There isn't one walking schedule for every joint. Standing or walking on the treated leg isn't the same as pickleball, riding, or a long trail outing. Your clinic directions should explain both walking and exercise. Worsening redness, warmth, fever, or illness needs prompt care. ## Where is the nearby QC Kinetix clinic? The Queen Creek clinic option is in Chandler at 1100 S.

Then ask about soreness, recovery time, cost, and activity limits. Your medicines may affect what's safe. Clear answers won't depend on broad promises. ## The clinic can answer your treatment questions QC Kinetix Chandler offers consultations.
