Knee arthritis.
Understand the whole joint.
Knee pain is rarely explained by one MRI line. A useful evaluation looks at cartilage, meniscus, subchondral bone, synovium, tendons, mechanics, strength, and the patient’s actual goals.
Why the painful knee needs context
Osteoarthritis describes structural change in the joint, but the degree of change on an X-ray or MRI does not perfectly predict pain or function. The practical question is which structures are contributing to symptoms now and which are modifiable.
I look at joint-space loss, effusion and synovitis, meniscal disease, subchondral bone, alignment, range of motion, quadriceps capacity, hip mechanics, activity demands, and prior treatment response. That creates a better foundation for deciding whether the next step is rehabilitation, medication, an injection, an orthobiologic procedure, or surgical consultation.
A treatment ladder, not a single injection
Load & strength
Improving strength, movement capacity, body composition, and activity dosing can change symptoms even when imaging does not change.
Medication & injections
Anti-inflammatory medication, corticosteroid, or hyaluronic acid can be reasonable in selected situations depending on goals and medical history.
PRP & BMAC
Regenerative procedures may be considered for selected patients after severity, alternatives, goals, and evidence are reviewed.
The goal is not to “treat the MRI.”
The goal is to improve pain, function, confidence, and activity while choosing the least invasive treatment that reasonably fits the problem.
PRP and BMAC are not interchangeable
PRP and bone marrow aspirate concentrate are different biologic preparations. I do not think of either as an automatic next step simply because arthritis is present.
Go deeper on the decision-making.
What patients usually want to know.
Do I need an MRI before a knee evaluation?
Not always. Existing X-rays or MRI can be helpful, but history, examination, and sometimes point-of-care ultrasound may answer important questions before additional imaging is ordered.
Can PRP help knee osteoarthritis?
PRP is one nonsurgical option that may be considered for selected patients with knee osteoarthritis. Expected benefit varies with disease severity, patient factors, product characteristics, and treatment goals.
Is BMAC the same as stem cell therapy?
BMAC is a bone marrow-derived concentrate containing multiple cell and signaling components. It is commonly marketed under the broad phrase “stem cell therapy,” but that phrase can imply more than the product actually contains or is proven to do.
When should I see a surgeon?
Progressive loss of function, severe structural disease, mechanical problems that are unlikely to respond to nonsurgical care, or failure of a reasonable nonsurgical plan may make surgical consultation appropriate.
