PRP for knee osteoarthritis uses a concentrated dose of your own platelets to calm the inflamed environment inside an arthritic knee, so you can stay active and delay or avoid a replacement. The published trials favor concentrated PRP over cortisone and gel, and dose is the variable that separates the trials that worked from the ones that did not. At Dynamic Athlete in Boulder, the protocol is Dynamic PRP+: high-dose, multi-spin PRP concentrating platelets over 10 billion (12 to 20 times baseline), co-delivered with Exosome-Containing Fibrin-Rich Plasma and placed into the joint under live ultrasound, by Dr. Aneesh Garg, DO, CAQ, The Regen Doc.
If a surgeon has framed a replacement as your next step, this is the second opinion: done right, PRP is one of the most studied ways to manage knee osteoarthritis without surgery.
The Decision
If your knee pain limits you but a surgeon has framed replacement as the path, you have a window. PRP is most predictable in mild to moderate arthritis, when the joint still has space and the goal is to buy back active years.
The real decision is whether the PRP you get is the kind the favorable evidence describes: high-dose, paired with a scaffold, and placed in the joint under ultrasound by a physician. A single-spin shot given by feel is a different product wearing the same name.
- PRP manages knee osteoarthritis without surgery. It calms the inflamed joint so you stay active and delay or avoid a replacement. It does not cure arthritis or regrow the joint.
- Dose decides the result. A 2024 American Journal of Sports Medicine review tied higher-dose PRP to better knee outcomes; the lower-dose 2021 JAMA trial showed none. Dynamic PRP+ is high-dose by design: platelets over 10 billion.
- The injectable goes in under live ultrasound, by a physician, not a technician. Blind knee injections often miss the joint; ultrasound confirms the PRP lands where the arthritis lives.
- over 90% of patients self-report 75% or greater improvement, all without surgery with Dynamic PRP+.
- HSA and FSA dollars typically apply, and Cherry financing spreads the cost monthly; insurance covers the consult.
Why Dynamic PRP+ is built for the arthritic knee
PRP is not one standardized product. For a knee, four decisions separate a protocol-grade injection from a commodity shot.
The dose is high, because the knee evidence rewards it
Concentrated PRP outperformed hyaluronic acid in a 2017 American Journal of Sports Medicine trial and a 2017 meta-analysis. A 2024 systematic review tied higher-dose PRP to better knee outcomes, while the lower-dose 2021 JAMA RESTORE trial found no benefit over placebo. Dynamic PRP+ concentrates platelets over 10 billion (12 to 20 times baseline), so the biology delivered into your knee matches the favorable evidence.
It is paired with Fibrin-Rich Plasma, not injected alone
Most clinics spin your blood once, draw off the platelet layer, and discard the rest. Dynamic PRP+ keeps it: the injection is co-delivered with Exosome-Containing Fibrin-Rich Plasma, used as a biological scaffold inside the joint, giving the platelets a matrix to work within rather than a dose dispersed in joint fluid.
It is placed in the joint under live ultrasound
A knee injection placed by feel does not reliably reach the joint. Landmark-only injections often miss the joint space and land in soft tissue, wasting the biologic. Live ultrasound lets the physician watch the needle enter the joint and confirm the PRP lands where the arthritis lives. Guidance is not an upsell; it is how an injectable is supposed to be done.
A physician performs it, and reports the outcomes honestly
Every Dynamic PRP+ procedure is performed by Dr. Aneesh Garg, DO, CAQ, The Regen Doc, never handed to a technician. The physician injecting your knee teaches regenerative medicine to other physicians. over 90% of patients self-report 75% or greater improvement, all without surgery. That is self-reported outcome data, not a guarantee; response varies with your tissue and the stage of arthritis.
PRP versus cortisone and gel for the knee
Three injections are commonly offered for an arthritic knee. They do different jobs; PRP is the one built for the long game.
| Injection | What it does | Best use |
|---|---|---|
| PRP (Dynamic PRP+) | A high dose of your own platelets to shift the joint’s inflammatory environment; favored over gel and cortisone over a year. | Active adults managing mild to moderate arthritis who want to delay or avoid a replacement. |
| Cortisone | Short-acting anti-inflammatory that quiets a flare; does not change the joint, and repeated use can be hard on cartilage. | Short-term relief of an acute flare, used sparingly. |
| Hyaluronic acid (gel) | Lubricates and cushions the joint for a season; does not alter the underlying disease. | Temporary symptom relief when a biologic is not chosen. |
Are you a candidate? Ask this before you book
The best responders are active adults whose knee pain limits them but whose joint still has space. When a knee is too advanced for PRP alone, the plan can step up to Dynamic Stem Cell+, physician-selected cells paired with High-Dose PRP. Print these questions for any provider.
- How concentrated is your PRP? A high-dose, multi-spin protocol, or a single-spin bedside kit at 2 to 3 times baseline?
- Is the injection placed in the joint under live ultrasound, or by feel using surface landmarks?
- Do you pair the PRP with a biological scaffold, or inject platelets alone?
- Does a physician prepare and personally perform the injection, and what are your own self-reported outcomes, stated honestly without a guarantee?
