Knee: Options and What the Evidence Actually Shows
Osteoarthritis, meniscus injury, and ligament problems dominate knee searches. Here is the standard ladder of care — and where autologous cell approaches enter the conversation.
Anatomy and clinical context
The knee is a weight-bearing hinge with cartilage, menisci, ligaments, and synovium that all age and fail differently. Pain is common; the diagnosis behind it is not always the same.
Most patients work through activity modification, physical therapy, bracing, oral meds, and image-guided injections before considering surgery. Regenerative injectates are often discussed in that middle band — after conservative care, before or instead of arthroplasty in selected cases.
The standard ladder of care
Conservative care first, then injections, then surgery when indicated. Cell therapy belongs inside that conversation — not above it.
- 1
Conservative care
Activity modification, physical therapy, weight management, bracing, and oral analgesics or anti-inflammatories.
- 2
Injections
Corticosteroid, hyaluronic acid, PRP, and orthobiologic injectates including same-day bone marrow or adipose-derived products when a physician recommends them.
Autologous cell approaches enter here — dose and donor age are what change the conversation.
- 3
Surgery
Arthroscopy for selected mechanical problems; osteotomy or partial/total knee replacement when joint disease is advanced.

Evidence
Where cell therapy fits
Large controlled trials of same-day, minimally manipulated products in knee OA have often landed at parity with cheaper comparators. That does not mean cells never help — it means dose and product type matter, and honest reading of the literature is part of good care.

The honest read — Same-day products keep landing at parity. The approved products that show more are the expanded ones — which makes dose, not enthusiasm, the variable worth acting on.
- 01Parity with comparator
MILES (Mautner, Nature Medicine 2023) compared BMAC, umbilical tissue, and SVF to corticosteroid in knee OA: none beat steroid at one year; MRI scores did not improve.
SourceMILES - 02Parity with comparator
Shapiro (AJSM 2017) compared BMAC to saline in contralateral knees — no difference on primary endpoints.
SourceShapiro 2017 - 03Dose-enabled pathway
Culture-expanded products such as Cartistem (Korea) and Stempeucel (India) illustrate pathways where therapeutic dose is engineered — the argument for banking younger cells and expanding later.
The sources
Both directions, cited plainly — the trials that found no advantage and the approvals that show what engineered dose looks like.

You are your own best donor
The most powerful medicine you'll ever use is already inside you.
Your stem cells are the body's repair crew — the same cells that build, heal, and renew tissue your whole life. Bank them now, at their most potent, and keep that regenerative power on your side for the years ahead.
Your cells, your biology, zero rejection.
No donor waitlist, no match required. These are your own stem cells — the safest, most natural material medicine has to work with.
Younger cells are stronger cells.
Your stem cells are more vigorous today than they'll ever be again. Bank them now and you lock in that youthful potency — 35-year-old cells stay available to the 55-year-old you.
One bank becomes a lasting supply.
Culture expansion turns a single collection into dose after dose — enough for a full course of treatment, not a one-shot souvenir. Rolling out now as our Florida cGMP lab comes online.
Ready the moment you need it.
When you and your physician decide it's time, your cells are waiting at peak potency — so the treatment works with the best version of you.
