Your own marrow, placed exactly where the damage is.
Bone marrow concentrate (BMC) is a regenerative injection made from your own bone marrow, harvested and concentrated in a single visit and delivered into a damaged joint or tendon under image guidance. At Ethos Integrative Medicine in Scottsdale, we use BMC for structural damage beyond the reach of PRP: moderate to advanced knee and hip arthritis, and partial rotator cuff tears with substantial tendon damage.
Most BMC conversations start with an imaging report. The language on it has moved from “mild” to “moderate” or “advanced,” and the specialist who reviewed it has started talking about a joint replacement as a matter of timing. Meanwhile, you’re still working at full speed and still active, and you have no interest in building your life around one joint.
This is BMC’s territory: joints with too much structural damage for platelets alone, and too much life left in them for a replacement. It’s one of four regenerative medicine treatments we offer, and your evaluation decides whether it’s the right one for you.
Bone marrow concentrate, also called bone marrow aspirate concentrate (BMAC), starts with a small draw of marrow from the back of your pelvis. We concentrate it on-site and inject it into the damaged tissue the same day. Nothing is grown in a lab, and nothing comes from a donor.
PRP delivers growth factors from your platelets and depends on the repair cells already living in the damaged tissue to respond. In a joint with significant cartilage loss, those cells are scarce. BMC brings its own, drawn from one of the body’s richest reservoirs of regenerative cells, along with the signaling proteins that direct them.
In a systematic review covering 4,626 patients, 94.4% of outcomes showed improvement at approximately 13 months. Your result will still depend on the joint and how much damage is present, which is why candidacy comes first.
The full mechanism is covered in our guide, What Is Bone Marrow Concentrate?
BMC is the right call when two things are true: your imaging shows structural damage that platelets alone are unlikely to resolve, and the joint still has enough cartilage left to respond. On a knee X-ray, that usually looks like visible narrowing of the joint space, with bone not yet resting on bone.
BMC is worth a serious look if:
BMC isn’t the second attempt after PRP fails. It’s a separate tool for a separate injury profile. If your knee is bone-on-bone, no injection will rebuild it, and you’ll hear that from us at your evaluation. Milder cartilage wear usually responds to PRP, and instability driven by loose ligaments is prolotherapy territory. When surgery is genuinely the better path, we’ll say so.

Your physician starts with your MRI or X-rays and a hands-on exam, grading the cartilage loss and pinpointing which structures are generating the pain. Those findings decide whether BMC, PRP, or another approach fits your joint. The evaluation is covered by our Leave You Better Promise: if you walk out without a clear picture of your options, we refund it.
BMC is two procedures in one visit, which makes it a longer appointment than PRP. First, the back of your pelvis is numbed and a small volume of marrow is drawn. That sample is concentrated on-site while the treatment area is prepared, and the concentrate is then delivered into the damaged tissue under image guidance.
Expect soreness in two places for several days: the harvest site and the treated joint. Most patients need a single BMC procedure. Improvement builds gradually over the following months, and you’ll return to full training in stages your physician sets with you.
Knee and hip arthritis carry BMC’s strongest evidence; partial rotator cuff tears are a more selective use.
The knee is BMC’s core indication. Bone marrow concentrate for knee pain comes into play when imaging shows moderate to advanced loss in a joint that still has years of hard use ahead of it.
Bone marrow concentrate for hip pain has its strongest evidence in osteoarthritis of the joint itself. Tendon problems around the hip are usually PRP cases. Because the hip sits deep beneath muscle, an injection placed without image guidance is largely guesswork.
Rotator cuff tendinopathy and smaller partial tears usually respond to PRP. BMC is reserved for partial-thickness tears with more substantial tendon damage, where the tissue needs more cellular support than platelets can supply. Tear size and location decide candidacy, and we’ll tell you where yours falls once we’ve reviewed your MRI.
The physician who evaluates your joint is the one who performs the marrow harvest and places the concentrate. The person who made the plan carries it out.
We offer four orthobiologic treatments: PRP, prolotherapy, MFAT, and BMC. Having all four means we never have to fit your injury to the one tool we happen to have. BMC gets recommended when your injury calls for it, and only then.
Your progress is tracked through Databiologics, so the question of whether BMC worked for you gets answered with data.
Ethos is private pay, so insurance has no say in how long we spend with you or which treatments you’re allowed to try.
Our regenerative patients come from across Scottsdale, Paradise Valley, and North Phoenix, and most of them have no plans to slow down. They want a joint that keeps up.

How does BMC work?
Should I get BMC or PRP?
Can BMC keep me out of surgery?
Is bone marrow concentrate the same as stem cell therapy?
Partly. BMC contains your own stem and progenitor cells, along with other regenerative cells and signaling proteins, concentrated and returned to your body in the same visit. It isn’t lab-expanded and doesn’t come from a donor, which is what most “stem cell therapy” advertising implies. We use the precise name so you know exactly what’s going into your joint.
Does the bone marrow draw hurt?
Your physician numbs the area before the draw. Most patients describe pressure and a brief, deep ache while the marrow is collected, followed by soreness at the site for a few days. If it worries you, bring it up at your evaluation, and your physician will walk you through exactly what to expect.
Is BMC covered by insurance?
Ethos is private pay and doesn’t bill insurance, and most plans don’t cover BMC wherever you have it done. We discuss pricing openly once your evaluation confirms BMC is the right treatment for your injury.
If surgery is on your calendar or in the back of your mind, get a regenerative opinion before you commit. Book a Discovery Call with our Scottsdale team, and we’ll give you a straight answer on whether BMC fits your joint.
