Knee Pain That Won't Quit — Even After Injections?
You've had cortisone. Maybe gel injections (hyaluronic acid). Maybe PRP or stem cell injections. You were told the next stop is a knee replacement. But you're not ready for that — and you shouldn't have to be.
LDRT addresses the inflammation that injections temporarily quiet, but never fix.

Why injections eventually stop working
Cortisone temporarily suppresses inflammation chemically — and that's the strength, but also the weakness. The underlying inflammatory cells continue producing pain-generating cytokines once the cortisone clears. Each subsequent injection often provides less relief and shorter duration. Gel injections add cushioning but do not address inflammation. PRP delivers growth factors but cannot interrupt the chronic inflammatory cycle in advanced osteoarthritis.
How LDRT is different
LDRT works on the inflammatory cells themselves — specifically modulating macrophages and reducing inflammatory cytokines in the joint capsule and surrounding soft tissues. The result, for many patients with advanced osteoarthritis who have exhausted injection therapy, is meaningful and lasting pain reduction. Without surgery. Without ongoing injections. Without downtime.
Who this is for
- Advanced knee osteoarthritis (often "bone on bone")
- Multiple cortisone or gel injections with diminishing returns
- PRP or stem cell injections that did not deliver lasting relief
- Patients told they need a total knee replacement but want to defer or avoid it
- Patients who are not surgical candidates due to other health considerations
- Both knees affected — yes, both can be treated
