# What to know before choosing joint care *Straight Answers | Regenerative Therapy Glendale* > Regenerative therapy Glendale questions answered plainly, including home care, PRP, insurance, severe wear and local visits. Glendale errands often mean several stops by car. You'll notice knee or hip stiffness while getting in and out. The answers below cover home care, procedures and urgent symptoms. They're meant to help before an exam. Start with the question closest to your concern. ## Sources 1. The AAOS third-edition clinical practice guideline for non-arthroplasty management of knee osteoarthritis is the orthopedic profession's own GRADE-style appraisal of the same options a regenerative clinic sells; it is the benchmark against which any 'regenerative' claim on this topic should be read, and it rates the strongest support for exercise, weight loss and self-management rather than for injectables. Brophy RH, et al. — [AAOS Clinical Practice Guideline Summary: Management of Osteoarthritis of the Knee (Nonarthroplasty), Third Edition.](https://pubmed.ncbi.nlm.nih.gov/35383651/). *The Journal of the American Academy of Orthopaedic Surgeons*, 2022. DOI: 10.5435/JAAOS-D-21-01233. 2. The 2019 ACR/Arthritis Foundation guideline makes STRONG recommendations for exercise, weight loss in people with overweight or obesity, self-efficacy and self-management programs, tai chi, cane use, tibiofemoral bracing, topical NSAIDs, oral NSAIDs and intra-articular glucocorticoid injection in knee OA. Notably it does NOT strongly recommend any biologic injectable. Kolasinski SL, et al. — [2019 American College of Rheumatology/Arthritis Foundation Guideline for the Management of Osteoarthritis of the Hand, Hip, and Knee.](https://pubmed.ncbi.nlm.nih.gov/31908163/). *Arthritis & rheumatology (Hoboken, N.J.)*, 2020. DOI: 10.1002/art.41142. 3. OARSI 2019 designates arthritis education plus structured land-based exercise (with or without dietary weight management) as CORE treatments for knee OA and strongly recommends topical NSAIDs (Level 1A), while strongly recommending AGAINST oral and transdermal opioids (Level 5). The treatments with the strongest evidence in this condition remain the least dramatic ones. Bannuru RR, et al. — [OARSI guidelines for the non-surgical management of knee, hip, and polyarticular osteoarthritis.](https://pubmed.ncbi.nlm.nih.gov/31278997/). *Osteoarthritis and cartilage*, 2019. DOI: 10.1016/j.joca.2019.06.011. 4. The Cochrane review of exercise for knee osteoarthritis found high-quality evidence that land-based therapeutic exercise provides short-term benefit in pain and physical function, sustained for at least 2-6 months after the programme ends, with mild transient soreness the only reported adverse effect across 45 trials. It is the best-evidenced treatment for this condition and it costs nothing per injection. Fransen M, et al. — [Exercise for osteoarthritis of the knee.](https://pubmed.ncbi.nlm.nih.gov/25569281/). *The Cochrane database of systematic reviews*, 2015. DOI: 10.1002/14651858.CD004376.pub3. 5. A randomized trial in the New England Journal of Medicine compared physical therapy against intra-articular glucocorticoid injection for knee osteoarthritis and found physical therapy produced better WOMAC outcomes at one year. When a clinic offers an injection, the comparator that matters is not 'nothing' - it is a course of supervised exercise. Deyle GD, et al. — [Physical Therapy versus Glucocorticoid Injection for Osteoarthritis of the Knee.](https://pubmed.ncbi.nlm.nih.gov/32268027/). *The New England journal of medicine*, 2020. DOI: 10.1056/NEJMoa1905877. 6. FDA states plainly that no stem cell, exosome, stromal vascular fraction, umbilical cord blood, Wharton's jelly or amniotic-fluid product has been approved for the treatment of ANY orthopedic condition - it names osteoarthritis, tendonitis, disc disease, tennis elbow, back pain, hip pain, knee pain, neck pain and shoulder pain individually. The only FDA-approved stem cell products in the United States are cord-blood-derived blood-forming stem cells for disorders of the hematopoietic system, and there are currently no FDA-approved exosome products. 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). *FDA*, 2020. 7. The RESTORE trial - a participant-, injector- and assessor-blinded RCT of 288 adults aged 50+ with symptomatic medial knee OA (Kellgren-Lawrence 2-3) - compared three weekly intra-articular PRP injections against saline placebo, with co-primary endpoints of 12-month knee pain and medial tibial cartilage volume on MRI. PRP did not beat placebo on either. It is the single best-designed test of the specific claim that PRP changes joint structure, and it was negative. Bennell KL, et al. — [Effect of Intra-articular Platelet-Rich Plasma vs Placebo Injection on Pain and Medial Tibial Cartilage Volume in Patients With Knee Osteoarthritis: The RESTORE Randomized Clinical Trial.](https://pubmed.ncbi.nlm.nih.gov/34812863/). *JAMA*, 2021. DOI: 10.1001/jama.2021.19415. 8. A four-arm, multicentre, single-blind phase 2/3 randomized trial of 480 knee OA patients (KL II-IV) compared autologous bone marrow aspirate concentrate, autologous adipose stromal vascular fraction and allogeneic umbilical-cord-tissue mesenchymal stromal cells against a corticosteroid injection control. At 12 months NONE of the three orthobiologic injections was superior to another, or to the corticosteroid control, and none of the four groups showed a significant change in MRI osteoarthritis score from baseline. No procedure-related serious adverse events occurred. 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/). *Nature medicine*, 2023.

Full rest can add stiffness. Strong muscles support the joint during movement. Your doctor can review creams, pills or a brace. Don't push through sharp pain just to finish a task. ## Is exercise worth trying before a procedure? Yes, when you can move safely. A regular program can build strength, motion and walking time. It isn't the same as trying several moves once. You'll begin at a level your joint handles. Then you'll add effort slowly. Tell your doctor or therapist if soreness keeps stopping progress. ## What is regenerative medicine? Regenerative medicine covers care prepared from blood or tissue and placed by needle into a sore joint. For PRP, a clinician takes blood from your arm and spins it. The kept portion has extra platelets. Those small blood parts stop bleeding and hold proteins used in healing. The blood portion returns to your joint by needle. QC Kinetix offers consultations with clinicians, called medical providers, who discuss these non-surgical choices. ## Can regenerative therapy rebuild cartilage? Cartilage forms a slick layer over each bone end. Research hasn't shown that regenerative therapy reliably rebuilds it in an arthritic joint. You may hear reports of less soreness or easier movement. That can matter, but it isn't proof of new cartilage. Comfort and rebuilding are two separate questions. Ask which result the treatment is meant to provide. ## Does insurance pay for regenerative medicine? Insurance coverage for this joint care is uncommon. You'll need to call your insurer before relying on a price. Ask the clinic's billing staff for the procedure and diagnosis codes. They're short sets of letters or numbers. One code names the procedure. The other names the health reason for it. Also request the full cost in writing. ## When does a sore joint need prompt care? Get care quickly when joint heat and swelling come with fever. After a fall, sudden trouble standing also needs attention. New limb weakness, lost feeling, or bladder or bowel trouble is urgent too. Those signs aren't a routine flare. You'll need to deal with them before arranging a planned joint procedure. ## What to bring when you call Keep your medicine names, joint notes and main daily goal nearby. The clinic can explain what happens during an exam. It can also describe available treatment choices and both locations. Schedule a free consultation: --- Understand the soreness. Know what to try.
