This is a patient demand report for orthopedic and sports medicine practice owners and marketing leads. It covers what patients pay for gel and PRP knee injections, what Medicare and commercial plans cover, what the evidence says and what patients find when they search before they call. The practice-side facts come first; the patient detail below is the evidence behind them.
For practice owners: what this search looks like from your side
A few facts, side by side.
In the suburban New York survey, 76 of 91 clinics offered orthobiologic knee injections. Among them, 98% of the orthopedic sports medicine practices offered PRP, and 84% of those practices, against 85% of alternative clinics, gave a PRP price when called. (Arthroscopy, Sports Medicine, and Rehabilitation, 2026)
In Chicago, alternative clinics charged significantly more for a single PRP injection than orthopedic sports medicine practices, and their prices varied more. (Orthopaedic Journal of Sports Medicine, 2025)
At one hospital-based practice that introduced a bundled-payment program for PRP, 37.76% of women used it against 18.18% of men, and 51.61% of non-white patients against 29.14% of white patients. (Orthopedic Research and Reviews, 2026)
Gel is covered for qualifying patients under the Medicare and Aetna policies covered below. PRP is not.
Of the eight ranking pages I could open for this comparison, six cited no study or coverage policy.
What those mean together for your practice is for you to work out.

What patients pay
Northwest Orthopaedic Specialists in Spokane, Washington posts a full self-pay menu. It lists Synvisc-One at $670 per joint, Euflexxa at $275 per dose, PRP at $600 unilateral and $900 bilateral, and a new-patient visit at $275. (NWOS self-pay pricing) The Orthopaedic Surgery Center in Youngstown, Ohio lists PRP at $2,068. (The Orthopaedic Surgery Center price list)
For PRP, a 2025 telephone survey of clinics in suburban New York found a median price of $1,000 at orthopedic sports medicine practices and $875 at alternative clinics. (Arthroscopy, Sports Medicine, and Rehabilitation, 2026)
The course is what patients end up paying for. According to the FDA dosing table in Aetna’s policy, Synvisc-One, Monovisc, Durolane and Gel-One are single injections. Euflexxa, Synvisc and Gelsyn-3 are three weekly shots, Hymovis is two, and Supartz FX and Hyalgan are five. (Aetna CPB 0179)
At the Spokane prices, a patient sees:
- Synvisc-One, one shot: $670 per knee.
- Euflexxa, three weekly doses: 3 × $275 = $825 per knee.
- PRP, one injection: $600 for one side. Three injections, as in the RESTORE trial, each charged at that listed price: 3 × $600 = $1,800.
One study compared full courses. Using typical charges at a large private orthopedic practice, a series of three PRP injections cost $1,433.67 more than a series of gel injections. (Arthroscopy, 2020)
Because neither PRP policy reviewed below pays for it, the PRP price is usually the full amount the patient pays, as my report on PRP injection cost vs surgery covers in more detail.
What Medicare pays your practice
| Gel (hyaluronic acid) | PRP (platelet-rich plasma) | |
|---|---|---|
| How it is billed | A product-specific HCPCS J-code (for example J7325 for Synvisc or Synvisc-One, J7323 for Euflexxa) plus CPT 20610, or 20611 with ultrasound guidance | CPT 0232T, which covers the injection plus harvesting, preparation and image guidance when performed |
| Shots per course | 1 to 5 depending on the product | No single standard. The RESTORE trial used 3 weekly injections |
| Medicare | Palmetto GBA covers it when its criteria are met | Noridian, the western US contractor, does not cover it for joint conditions |
| Aetna commercial plans | Medically necessary when criteria are met | Experimental, investigational or unproven for knee osteoarthritis |
The billing codes come from Aetna’s viscosupplementation policy, which lists 13 J-codes for gel products and names 0232T among codes not covered for those indications. (Aetna CPB 0179) Medicare contractor Palmetto GBA states that 20610 or 20611 “may be billed for the intra-articular injection in addition to the drug.” (CMS billing article A59030)
Gel. Palmetto GBA, the Medicare contractor for states including Georgia, Tennessee and the Carolinas, requires X-ray evidence of arthritis, at least 3 months of failed conservative care such as physical therapy or anti-inflammatories, and failure of or a reason to avoid a steroid injection. It also says gel is not covered “as the initial treatment” of knee arthritis. (CMS LCD L39260) Aetna’s commercial policy has similar steps and excludes patients scheduled for a knee replacement within 6 months. (Aetna CPB 0179)
Palmetto GBA covers a repeat gel series only if “at least 6 months have elapsed since the prior series,” the patient improved after the last one and symptoms have come back. Aetna uses the same six-month gap. That caps gel at two series per knee per year. For a cash patient at the Spokane prices, two Synvisc-One series come to 2 × $670 = $1,340 a year, and two Euflexxa series 2 × $825 = $1,650.
A qualifying patient with Original Medicare pays the 2026 Part B deductible of $283, then usually 20% of the Medicare-approved amount. (Medicare.gov)
PRP. Noridian, the Medicare contractor for California and much of the western US, including Washington state, calls its policy “a non-coverage policy for all Platelet Rich Plasma injections and/or applications as a means of managing musculoskeletal injuries and/or joint conditions.” (CMS LCD L39058) Aetna lists PRP for osteoarthritis, including the knee, as experimental, investigational or unproven. (Aetna CPB 0784)
What the evidence patients read says
Guidelines. The American Academy of Orthopaedic Surgeons guideline adopted in August 2021 says gel injections are “not recommended for routine use” for knee arthritis (moderate strength). It says PRP “may reduce pain and improve function” (limited strength, downgraded for inconsistent evidence). (AAOS guideline)
PRP against gel. A 2026 meta-analysis of 21 randomized trials with 1,790 patients found no pain advantage for PRP at 3 and 6 months, a small advantage at 12 months, and substantial heterogeneity and risk of bias across studies. (Arthroscopy, 2026) A 2025 meta-analysis limited to 15 double-blind trials with 1,632 patients found PRP better than gel at 12 months on a standard arthritis score. (Arthroscopy, 2025) A separate review of 79 abstracts of such reviews found spin in every one, most often a conclusion claiming benefit despite high risk of bias in the underlying trials. (European Journal of Orthopaedic Surgery & Traumatology, 2025)
Each against placebo. In the RESTORE trial, 288 patients received three weekly injections of PRP or saline. After 12 months, pain scores improved by 2.1 points with PRP and 1.8 with saline, a difference that was not significant. (JAMA, 2021) For gel, a BMJ review of 169 trials found that in the large placebo-controlled trials the pain reduction was 2.0 mm on a 100 mm scale, below the smallest difference the authors counted as clinically important, with a higher risk of serious adverse events (relative risk 1.49). (BMJ, 2022)
Side effects. Across 24 trials, the odds of complications with PRP were not significantly different from gel. Almost all complications were mild or moderate. (Arthroscopy, 2025)
Value. One model put a series of PRP at $8,635.23 per quality-adjusted life year and gel at $5,331.75, both under the $50,000 threshold the authors used for cost-effective. (Arthroscopy, 2020) A second analysis based on Medicare fee schedules found PRP cost-effective against gel and saline only if the whole 12-month course cost less than $1,192.08. (Arthroscopy, 2020)
Surgery later. In observational studies, patients who had gel injections went 9.8 months longer before a knee replacement, though the authors say causality cannot be concluded, and there was too little data on PRP. (Journal of Clinical Medicine, 2022) Replacement prices are covered in my reports on knee replacement cost and partial vs total knee replacement cost.
Who patients are
A patient who gets covered gel has, by policy, already had X-ray evidence, at least 3 months of conservative care and a steroid injection that failed or was ruled out. Aetna excludes patients scheduled for a knee replacement within 6 months, so covered gel patients are not booked for a replacement in the next six months.
PRP patients pay cash under every policy reviewed here. When one hospital-based practice offered a bundled PRP price, women and non-white patients used it at higher rates than men and white patients.
Questions patients ask before they book
These are the questions your page and your front desk need to answer.
- Does the patient meet their plan’s criteria for gel, and does a steroid injection have to come first? A good page lists the criteria in plain words.
- Which gel product, and how many shots? A good page prices the full course, since one shot and five shots cost very differently.
- For PRP, how many injections, and is each one priced separately? A good page posts both prices.
- Does the price include the visit and ultrasound guidance? A good page shows the new-patient visit if it is a separate line.
- What did the practice’s own patients report at 6 and 12 months? A good page shows them if the practice tracks them.
What a page that wins this search includes
When I reviewed the pages that rank for this comparison, most were clinic blogs or health content sites. Of the eight I could open, six linked to no study, CMS policy or AAOS guideline at all, and the result titled most directly for the comparison, “PRP vs Gel vs Steroid Knee Injections”, listed no prices at all. This report puts posted prices, coverage rules and the published evidence side by side.
A page that wins this search includes:
- Per-shot and per-course prices. The course total is where the two injections separate.
- Medicare, commercial and self-pay coverage on separate lines, with gel’s criteria spelled out.
- A bundled PRP price, if the practice offers one.
- The evidence linked both ways, including the AAOS guideline, RESTORE and the BMJ review.

Frequently asked questions
Is PRP more expensive than gel injections for the knee? Per shot, not always: one Spokane clinic lists one-side PRP at $600 and Synvisc-One at $670 per joint. Over a course, one study put a three-shot PRP series $1,433.67 above a gel series.
Does Medicare cover gel injections for knee arthritis? Under Palmetto GBA’s policy, yes, when criteria are met, including X-ray evidence, at least 3 months of conservative care and a failed or unsuitable steroid injection. A repeat series needs at least 6 months’ gap.
Does Medicare cover PRP for the knee? Noridian’s policy is a non-coverage policy for PRP in joint conditions, and Aetna treats it as experimental for knee osteoarthritis.
How many gel injections does a course take? It depends on the product: one for Synvisc-One, Monovisc, Durolane or Gel-One, three for Euflexxa or Synvisc, and five for Supartz FX or Hyalgan.
Does PRP work better than gel? Some meta-analyses report a small advantage for PRP at 12 months, but the trials vary in quality, and a large placebo-controlled trial found PRP no better than saline.
