REGENERATIVE JOINT TREATMENT · CARLSBAD AND LAGUNA HILLS
Lasting relief for a bad knee, without a replacement
Physical therapy didn't stick, and cortisone shots buy less time every round. Dr. Steve Derrington goes after what's causing the knee pain, so you can get back to the life you've had to put on hold.
Three things decide whether a treatment like this works:
A full hands-on exam with ultrasound
Every injection placed under imaging, never by feel
Provider experience. We’ve performed more Regenexx regenerative procedures than any clinic in California
Individual results vary.

Meet Dr. Steve
Derrington
At Macalester he played baseball and football and made all-conference. He spent his spare hours in the athletic training room, working on other people’s injuries so they could get back on the field. That’s still the job.
After medical school he did his residency in Physical Medicine and Rehabilitation, then a fellowship in Napa in interventional spine and sports medicine, where he learned to place treatments under ultrasound and live x-ray. He teaches that placement to other physicians now, so the hands doing the work are the ones the rest learn from.
He performs every procedure himself, and the cells are processed in his own lab, on site, the same day. He still does CrossFit, so he knows what it costs somebody to give up something they love.

How it works
Four steps between here
and an answer
Our treatments are self-pay. Insurance doesn't cover them. The plan gets built around what the knee needs rather than around what a policy will pay for. Payment plans are available through Cherry and CareCredit, and the team goes over them after your consultation.

FAQ
Frequently Asked Questions
What does it cost, and will insurance cover any of it?
Treatment is self-pay, and insurance doesn't cover it. HSA and FSA funds can be used. The price depends on the joint and on what Dr. Derrington finds when he examines you, so you get the exact figure at your consultation.
How long before I feel better, and would I need more than one treatment?
Results vary more than anyone would like. Some people notice a change in a few weeks and others take a few months. Dr. Derrington tells you what's reasonable for your joint before you commit to anything.
What if I'm too far gone for this?
Dr. Derrington will tell you at your consultation. Some joints are past the point where this helps, and some people are better served by a surgeon. If that's you, he'll say so and point you at one.
I had an injection like this somewhere else and nothing happened.
Common enough to be worth a conversation. When one of these fails, the cause is usually the wrong structure, a needle placed by feel instead of under imaging, or a preparation too dilute to do much. None of that is a verdict on your body.
Do I need imaging, and who am I actually speaking to?
No imaging needed to start. The fifteen-minute call is with Dr. Derrington's team. You meet Dr. Derrington himself at your consultation, and that's where he goes through any imaging with you.
