# What to compare before paying for joint care *Costs and Choices — Biologic Injections Surprise* > Biologic injections Surprise cost and treatment choices explained simply, from home care and cortisone to PRP and surgery alternatives. Start with care that costs little and asks little of you. Avoid the movement that brings soreness. Keep moving in other ways and continue comfortable exercise. Slow weight loss can reduce strain when extra weight is a concern. These steps can still help after a clinic procedure. A high price doesn't prove better relief. Get the full charge in writing before you pay. ## What to ask about prp injection cost Platelet-rich plasma (PRP) comes from a blood sample spun in a machine to collect platelets, the small parts that stop bleeding. The prepared blood then goes beside the sore area. Offices don't all make it the same way. Two prices can cover different care, like repair bills with different parts. Ask whether the total includes the blood draw and follow-up visits. Find out whether the office expects one treatment or several. Ask what you'll owe if the first one doesn't help enough. Get each answer in writing. You'll often pay for PRP yourself. Don't let a discount rush your choice. ## What studies say when you ask does PRP work Researchers compare PRP with cortisone or a salt-water shot. Some studies find more relief from PRP after several months. Other studies find no extra relief over salt water. It can help some people, but the result isn't certain. Ask what improvement would matter in your daily life. Walking farther or sleeping better gives you a clear test. Then ask when to judge the treatment. A knee result won't answer a shoulder question. QC Kinetix offers natural pain treatments, clinic procedures that use your prepared blood for the shot. Here, natural refers to using your blood. It doesn't mean the treatment works for every joint. ## What to compare with cortisone Cortisone often costs less and may be covered. It can work faster, though relief may be brief. PRP often means paying cash and waiting longer for an answer. Neither choice fixes every sore joint. Compare the total price and time away from usual activity. Ask whether you'll keep doing your current exercises. If surgery has come up, ask whether waiting could make it harder. Ignore words such as advanced or natural when you compare care. Focus on what the procedure contains, what relief is likely and what you'll pay. ## Sources 1. The AAOS third-edition clinical practice guideline on non-arthroplasty management of knee osteoarthritis contains 29 recommendations and explicitly highlights intra-articular corticosteroid, hyaluronic acid AND platelet-rich plasma as the areas where better research is still needed - including osteoarthritis characterisation, subgroup and severity stratification, control for bias, and cost-effectiveness analysis.

The 2015 Annals network meta-analysis of 137 studies (33,243 participants) compared oral and injected drugs for knee OA and found ALL interventions significantly outperformed oral placebo for pain, with intra-articular hyaluronic acid the most efficacious (effect size 0.63) and acetaminophen the least (0.18). Intra-articular treatments outperformed NSAIDs, which the authors noted may partly reflect the integrated effect of the injection process itself.

DOI: 10.7326/M14-1231. 3. The only randomized controlled trial of alpha-2-macroglobulin for knee osteoarthritis allocated 75 patients with KL grade 2-3 disease to A2M-rich concentrate, conventionally prepared PRP, or methylprednisolone, with 12-week follow-up. The A2M group improved significantly from baseline on VAS, WOMAC, KOOS and Tegner; the PRP group improved on none; the steroid group improved on Lysholm only. Critically, the CHANGE in scores did not differ significantly between the three groups - A2M was comparable to, not better than, PRP and corticosteroid.

The largest head-to-head trial of cell-based orthobiologics to date randomised 480 patients with KL II-IV knee OA across four arms: autologous bone marrow aspirate concentrate, autologous adipose stromal vascular fraction, allogeneic umbilical cord tissue-derived MSCs, and a corticosteroid injection control. At 12 months NONE of the three orthobiologic injections was superior to another or to the corticosteroid control on either co-primary endpoint (VAS pain, KOOS pain), and none of the four groups showed a significant change in MRI osteoarthritis score from baseline. No procedure-related serious adverse events were reported.

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.

A network meta-analysis restricted to LARGE randomized trials (at least 100 patients per group; 57 RCTs, 22,795 participants, 18 intra-articular interventions) found treatment effects were consistently larger in the 35 high-risk-of-bias trials than in the 22 low/unclear-risk trials. In the main analysis excluding high-risk trials, triamcinolone had the highest probability of exceeding the minimal important difference at weeks 2 and 6; hyaluronic acid had no effect on pain (SMD -0.04, 95% CrI -0.19 to 0.11, 11 trials) but higher odds of dropouts due to adverse events (OR 2.01) and of serious adverse events (OR 1.86). The effects of 16 of the 18 interventions were smaller than the MID and most were consistent with placebo effects.

RESTORE, the largest and most rigorously blinded placebo-controlled PRP trial in knee OA (n=288, participant-, injector- and assessor-blinded), gave three weekly injections of a commercial leukocyte-poor PRP or saline. At 12 months the change in knee pain was -2.1 vs -1.8 points (difference -0.4; 95% CI -0.9 to 0.2; P=.17) and the change in medial tibial cartilage volume was -1.4% vs -1.2% (difference -0.2%; P=.81). Twenty-nine of 31 prespecified secondary outcomes showed no between-group difference. The authors concluded the findings do not support the use of PRP for knee OA.

DOI: 10.1001/jama.2021.19415. 8. A meta-analysis of 34 RCTs (1,403 PRP knees vs 1,426 controls) found WOMAC favoured PRP over placebo at 12 months and over hyaluronic acid at 6 and 12 months, and favoured PRP over steroids on VAS pain, KOOS pain, daily function and quality of life at 6 months. Crucially, the authors state that the superiority of PRP DID NOT REACH the minimal clinically important difference for any outcome and the quality of evidence was low.
