# What do people ask before a joint procedure? *stem cell therapy Surprise | Common Questions Answered* > Straight answers to common stem cell therapy Surprise questions about the visit, walking, recovery, cost, and warning signs. This page gives straight answers to common questions about a joint procedure. They’re general because your health and sore joint still need an exam. Among its choices, QC Kinetix offers regenerative treatments, office procedures where a doctor or another licensed medical provider may use spun marrow, washed fat, or platelets separated from your blood. I’d ask anything still unclear before agreeing. ## Sources 1. A retrospective comparison of 523 bone marrow aspiration procedures against 435 open iliac crest bone graft harvests found aspiration significantly reduced complications - relevant because marrow aspiration for a joint injection is a real procedure with a real, if low, complication rate. Hernigou P, et al. — [Morbidity of graft harvesting versus bone marrow aspiration in cell regenerative therapy](https://pubmed.ncbi.nlm.nih.gov/24658874/). *Int Orthop*, 2014. DOI: 10.1007/s00264-014-2318-x. 2. In 96 patients, concentrated bone marrow aspirate contained a mean of 26.3 million nucleated cells per mL but only about 1,422 colony-forming units of connective tissue progenitors, and the nucleated cell count had negligible predictive value for how many progenitor cells were actually present (r-squared 0.28). Muench LN, et al. — [Nucleated Cell Count Has Negligible Predictive Value for the Number of Colony-Forming Units for Connective Tissue Progenitor Cells (Stem Cells) in Bone Marrow Aspirate Harvested From the Proximal Humerus During Arthroscopic Rotator Cuff Repair](https://pubmed.ncbi.nlm.nih.gov/33581306/). *Arthroscopy*, 2021. DOI: 10.1016/j.arthro.2021.01.064. 3. Mesenchymal stromal cells make up only about 0.001 to 0.01 percent of the nucleated cells in bone marrow, so the harvesting and processing technique - aspiration site, syringe size, centrifuge speed and time - materially determines what ends up in the syringe, and no consensus protocol exists. Jeyaraman M, et al. — [Impact of the Process Variables on the Yield of Mesenchymal Stromal Cells from Bone Marrow Aspirate Concentrate](https://pubmed.ncbi.nlm.nih.gov/35200410/). *Bioengineering (Basel)*, 2022. DOI: 10.3390/bioengineering9020057. 4. In a 480-patient, four-arm, multicenter randomized phase 2/3 trial, none of three orthobiologic cell injections - autologous bone marrow aspirate concentrate, autologous adipose stromal vascular fraction, or allogeneic umbilical cord tissue-derived mesenchymal stromal cells - was superior to any other, or to a corticosteroid injection control, on pain at 12 months. Mautner K, et al. — [Cell-based versus corticosteroid injections for knee pain in osteoarthritis: a randomized phase 3 trial](https://pubmed.ncbi.nlm.nih.gov/37919438/). *Nat Med*, 2023. DOI: 10.1038/s41591-023-02632-w. 5. FDA states in its consumer alert that the only FDA-approved stem cell products in the United States are blood-forming stem cells derived from umbilical cord blood, approved for disorders of the blood-forming system, and that NONE of these products - stem cells, stromal vascular fraction, umbilical cord blood, Wharton's jelly or amniotic fluid - has been approved for the treatment of any orthopedic condition, including osteoarthritis, tendonitis, disc disease, tennis elbow, back pain, hip pain, knee pain, neck pain or shoulder pain. US Food and Drug Administration, Center for Biologics Evaluation and Research — [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). *null*, 2020. 6. 21 CFR 1271.10(a) sets the four criteria a human cell or tissue product must meet to be regulated SOLELY under section 361 of the Public Health Service Act: it must be minimally manipulated; intended for homologous use only, as reflected by labeling and advertising; not combined with another article beyond water, crystalloids or a preserving agent; and either have no systemic effect and not depend on the metabolic activity of living cells, or else be for autologous use, use in a close blood relative, or reproductive use. US Code of Federal Regulations, Title 21 — [21 CFR 1271.10 - Are my HCT/P's regulated solely under section 361 of the PHS Act](https://www.ecfr.gov/current/title-21/chapter-I/subchapter-L/part-1271/subpart-A/section-1271.10). *null*, 2004. ## How is stem cell therapy done during an office visit? The clinic reviews your health, medicines, and joint first. A doctor may draw marrow from your pelvis or remove a small amount of fat. The clinic prepares it, then puts the finished liquid at your joint. Ask which steps will happen in your case. ## What can I do when I get home? Your written directions need to cover walking, driving, work, wound care, and medicine. The joint wound may need different care from the spot on your pelvis or abdomen. Don’t copy another person’s schedule, because your procedure may differ. ## Can I walk after the visit? Some walking may be allowed, but the safe amount varies. Ask whether you’ll need a cane, brace, or help getting inside. If walking makes the soreness climb later, tell the doctor how far you went. ## How long might my knee stay sore? There isn’t one recovery time for every knee procedure. Ask when the knee and the sore spot on your pelvis or abdomen may settle. You’ll also need to know when activity can increase and when follow-up occurs. ## What does stem cell therapy cost in Arizona? There isn’t a reliable Arizona average in the information used here. Ask for a written price with the procedure and follow-up listed. I’d also ask what you owe if the doctor stops before drawing enough marrow or fat. ## Which side effects need a call? Call promptly for fever, spreading redness, wound drainage, rising soreness, or calf swelling. A joint that is hot and swollen with fever may need urgent care. Get the after-hours number before leaving, so you won’t have to search later. ## What can I ask at the consultation? Take a list of your medicines, old joint records, and notes on the tasks that now hurt. Ask what the exam suggests and which non-surgical choices fit. Your first consultation won’t cost anything. Get the procedure, recovery, follow-up, and price explained in plain words. Ask when surgery or another opinion may make more sense. You can wait to decide until those answers are clear.
