The 2015 Cochrane review of 27 trials (1,767 participants) found intra-articular corticosteroid better than sham for knee OA pain (SMD -0.40, 95% CI -0.58 to -0.22; NNTB 8), but the benefit decayed with time: moderate at 1-2 weeks, small at 13 weeks, and no evidence of any effect at 26 weeks. All outcomes were graded LOW quality. Jüni P, et al. — [Intra-articular corticosteroid for knee osteoarthritis.](https://pubmed.ncbi.nlm.nih.gov/26490760/). *Cochrane Database Syst Rev*, 2015. DOI: 10.1002/14651858.CD005328.pub3. 2. A meta-analysis of eight RCTs found the pooled effect of intra-articular corticosteroid on knee pain was -0.58 SMD (95% CI -0.88 to -0.27; NNT 5.1), with the effect approaching statistical insignificance at four months and a non-significant pooled risk ratio for adverse effects of 0.95.

DOI: 10.1097/PHM.0000000000001384. 3. A meta-analysis of 10 RCTs of RECURRENT intra-articular corticosteroid injections (2-8 injections per patient) found they often gave inferior or non-superior relief compared with hyaluronic acid, PRP, saline or orgotein at 3 months and beyond, and no benefit over placebo in pain or function at 12-24 months. Donovan RL, et al. — [Effects of recurrent intra-articular corticosteroid injections for osteoarthritis at 3 months and beyond: a systematic review and meta-analysis in comparison to other injectables.](https://pubmed.ncbi.nlm.nih.gov/36108937/). *Osteoarthritis Cartilage*, 2022. DOI: 10.1016/j.joca.2022.07.011. 4. In a 2-year double-blind RCT of 140 patients with symptomatic knee OA and ultrasound synovitis, 40 mg intra-articular triamcinolone every 12 weeks produced significantly greater cartilage volume loss than saline (index compartment cartilage thickness change -0.21 mm vs -0.10 mm; between-group difference -0.11 mm, 95% CI -0.20 to -0.03) with no significant difference in knee pain. McAlindon TE, et al. — [Effect of Intra-articular Triamcinolone vs Saline on Knee Cartilage Volume and Pain in Patients With Knee Osteoarthritis: A Randomized Clinical Trial.](https://pubmed.ncbi.nlm.nih.gov/28510679/). *JAMA*, 2017. DOI: 10.1001/jama.2017.5283. 5. A 2-year double-blind RCT of triamcinolone every 3 months versus saline found NO difference in joint space loss between groups and significantly improved pain and stiffness with repeated steroid injections, and the authors concluded that long-term intra-articular steroid injection is safe for the anatomical structure of the knee. Raynauld JP, et al. — [Safety and efficacy of long-term intraarticular steroid injections in osteoarthritis of the knee: a randomized, double-blind, placebo-controlled trial.](https://pubmed.ncbi.nlm.nih.gov/12571845/). *Arthritis Rheum*, 2003. DOI: 10.1002/art.10777. 6. The RUbICOn mixed-methods HTA study, commissioned specifically to address uncertainty about recurrent injections, combined a UK primary-care cohort (2005-2020) linked to hospital data with a safety analysis, patient and clinician interviews, and a three-round Delphi to set research priorities - the current formal acknowledgement that the long-term risks and benefits of repeat injections remain unresolved. Whitehouse MR, et al. — [RecUrrent Intra-articular Corticosteroid injections in Osteoarthritis: the RUbICOn mixed-methods study.](https://pubmed.ncbi.nlm.nih.gov/41217479/). *Health Technol Assess*, 2025. DOI: 10.3310/LFAJ9337. 7. Medicare Part B claims show hyaluronic acid injections rose from 1,090,503 services in 2012 to 1,209,489 in 2018 and total costs from $290.10 million to $325.02 million (2020 dollars) - utilisation and spending both increased despite the AAOS recommendation against routine use. Zhu KY, et al. — [Hyaluronic Acid Injections for Knee Osteoarthritis: Has Utilization Among Medicare Beneficiaries Changed Between 2012 and 2018?](https://pubmed.ncbi.nlm.nih.gov/35580316/). *J Bone Joint Surg Am*, 2022. DOI: 10.2106/JBJS.21.00832. 8. A systematic review of 105 clinical orthopaedic PRP studies found only 11 (10%) described the preparation protocol well enough to be repeated, and only 17 (16%) reported quantitative metrics on the composition of the final PRP product - so 'PRP' in one trial is frequently not the same product as 'PRP' in another. Chahla J, et al. — [A Call for Standardization in Platelet-Rich Plasma Preparation Protocols and Composition Reporting: A Systematic Review of the Clinical Orthopaedic Literature.](https://pubmed.ncbi.nlm.nih.gov/29040132/). *J Bone Joint Surg Am*, 2017. DOI: 10.2106/JBJS.16.01374. 9. The RESTORE randomized trial (288 participants, leukocyte-poor PRP, 3 weekly injections) found no significant difference from saline placebo at 12 months in knee pain (-2.1 vs -1.8 points; difference -0.4, 95% CI -0.9 to 0.2) or in medial tibial cartilage volume (-1.4% vs -1.2%), with 29 of 31 secondary outcomes also showing no between-group difference. 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. 10. FDA's HCT/P guidance sets out the minimal-manipulation and homologous-use criteria that decide whether a human cell or tissue product is regulated solely under 21 CFR Part 1271 (section 361) or requires a biologics licence; cell-based orthopaedic injections that fall outside those criteria are unapproved drugs and biological products, and no cell-based product is FDA-approved to treat osteoarthritis. U.S. Food and Drug Administration — [Regulatory Considerations for Human Cells, Tissues, and Cellular and Tissue-Based Products: Minimal Manipulation and Homologous Use - Guidance for Industry and FDA Staff](https://www.fda.gov/regulatory-information/search-fda-guidance-documents/regulatory-considerations-human-cells-tissues-and-cellular-and-tissue-based-products-minimal). *U.S. Food and Drug Administration*, 2020. 11. A systematic review of eight studies (299 knees, mean follow-up 12.9 months) found BMAC improved 34 of 36 patient-reported outcomes from baseline, but all three comparative studies failed to show BMAC superior to other biologic injections or to placebo - a finding the authors weigh against its high cost. Keeling LE, et al. — [Bone Marrow Aspirate Concentrate for the Treatment of Knee Osteoarthritis: A Systematic Review.](https://pubmed.ncbi.nlm.nih.gov/34236913/). *Am J Sports Med*, 2022. DOI: 10.1177/03635465211018837. ## How much does a cortisone shot cost without insurance? There isn't one dependable average because exam and added service charges differ by office. Ask for every charge in writing before booking, including whether paying cash changes your final total. ## Does Medicare pay for hyaluronic acid injections? Medicare has paid for many gel shots, but coverage varies by joint, case, and plan. Ask the office to check before each visit, explain what you may owe, and say whether prior approval is required. ## What changes the PRP knee injection cost? PRP is platelet-rich plasma made by spinning your blood, gathering liquid plasma and platelets that carry healing signals. Concentrated PRP gathers more platelets, so ask which form and how many visits the price covers before agreeing to care. ## What can help joint soreness at home? Ease the activity that caused the ache, but move the joint only as far as feels comfortable. Use warmth for stiffness and a covered cold pack for swelling, then call if normal tasks keep getting harder. ## When does a sore joint need care today? Get prompt care when the joint becomes hot and swollen while you have fever. Sudden numbness, weakness, deformity, or trouble standing also needs help now, especially after a fall, so don't wait at home. ## What if the soreness does not settle? Regenerative treatments at QC Kinetix include PRP and concentrated PRP, both prepared from your blood. A doctor examines the joint first, then explains fit, cost, recovery, and later care if soreness remains. ## What if the soreness keeps returning? A medical provider examines the joint and asks when the soreness began. Bring earlier X-rays, your medicine list, and notes about painful tasks. The provider explains which non-surgical choices may fit your cause. Ask about the full price, recovery, and warning signs before deciding.
