Regenerative medicine in Honolulu, without the snake oil

Orthobiologics are injections made from your own blood or bone marrow — PRP, BMAC, and A2M — that may reduce pain and improve function in selected patients. They do not regrow cartilage. Dr. Paul Morton, a fellowship-trained hip and knee surgeon, diagnoses and stages the joint first, delivers the biologic under image guidance, and says plainly when a covered injection, therapy, or surgery would serve you better.

Orthobiologics are treatments built from substances found naturally in your own body — platelets, growth factors, cytokines, marrow cells, plasma proteins — plus hyaluronic acid, which your joints make themselves. Concentrated and placed precisely where tissue is irritated or damaged, they aim to change the chemistry inside a joint or tendon: less inflammatory signaling, less pain, better function.

What they can and can't do: in selected patients, orthobiologics may reduce pain and improve function, and for some that means surgery delayed or avoided. They do not regrow cartilage or reverse arthritis, and the research behind each one is at a different stage — which is why every treatment on this page is labeled honestly below.

The range of problems they are used for is wide: cartilage wear from osteoarthritis, soft-tissue tears and tendinopathy, bursitis, muscle strains, and ligament sprains. They're also worth considering when an injury simply isn't healing the way it should — or when physical therapy and pain medication haven't delivered.

Every joint at this practice starts with the same question: what's the least invasive treatment that will actually work for this patient? The ladder runs from activity modification and physical therapy, through conventional injections (cortisone, hyaluronic acid gel), to biologics — PRP, BMAC, A2M — and iovera° cryoneurolysis for nerve-driven knee pain. Surgery sits at the top of the ladder, used when it's genuinely the right rung — and skipping straight to it is as much a failure of judgment as never getting there. The full ladder for arthritic joints is laid out on the hip and knee arthritis page.

This is the comparison patients ask for most, so here it is in one place. The figures are the ones Dr. Morton quotes in clinic and uses across this site; none of these injections regrows cartilage, and each row links to its full page.

Read across a row and the pattern is clear: cortisone for a flare you need calmed now, gel for month-to-month cushioning (often covered), PRP for a longer biologic effect in a knee that still has cartilage to protect, and BMAC reserved for specific jobs — chiefly early hip AVN. Which rung fits is a diagnosis question, decided at a consultation with imaging.

Each treatment has a lane where evidence and experience support it — and a label that says how strong that evidence is:

Two more products come up constantly in regenerative-medicine marketing, and they deserve honest context. Dr. Morton offers PRP, BMAC, and A2M only — each prepared from your own tissue in the same visit, which is what keeps them within FDA rules.

Adipose-derived mesenchymal stem cells (AD-MSCs) are harvested from body fat. In the laboratory these cells can differentiate into bone, cartilage, and muscle cells, which is why they attract intense research interest — but research interest is not the same as proven joint treatment, and products that are enzymatically processed or expanded in a lab fall outside what a clinic may legally offer without FDA approval.

Amniotic tissue and umbilical-cord products come from donated tissue and carry growth factors and healing proteins. Their best-established use is in chronic wounds and skin ulcers — worth remembering when a clinic markets them as a joint cure. The FDA's consumer warning about unapproved stem cell products is explicit: unapproved stem cell products have caused serious harm, and "stem cell" marketing for arthritis is a red flag, not a credential. The same standard applies to every biologic on this site: for osteoarthritis, cell-based injections remain experimental — many studies have been done, most show minimal improvement, and none has demonstrated that stem cells reliably fix orthopedic problems.

For patients who choose joint preservation, Dr. Morton uses a structured framework so treatments reinforce each other and the response can actually be measured. It is a starting point adjusted to your diagnosis and your response — never a fixed package of shots sold in advance. If the first series doesn't earn its keep, the plan changes; that is the whole point of tracking the response.

Step 1 — Diagnosis first

Every plan begins with a hands-on office examination to pinpoint the source of pain and any functional limits, plus up-to-date imaging — X-ray, MRI, or ultrasound — so treatment targets the actual problem rather than a guess.

Step 2 — A typical six-week treatment phase

Why PRP plus hyaluronic acid? The two work on different timelines: HA improves the joint's glide and cushioning within a few weeks, while PRP's effect on inflammatory signaling builds more gradually. Some studies suggest the combination outperforms either alone in osteoarthritis, though the evidence is not settled. Why laser? MLS laser is offered to patients who want an extra, drug-free tool against swelling and soreness during the series. The AAOS clinical practice guideline on non-arthroplasty management of knee osteoarthritis (3rd edition, 2021) rates laser evidence as limited — as it does PRP itself — so it's an option, not a requirement.

Step 3 — Measure the response

A follow-up visit after the series asks the only question that matters: did it help, by how much, and for how long? Honesty cuts both ways here. Meta-analyses favor PRP over hyaluronic acid at six to twelve months, but the RESTORE trial (Bennell et al., JAMA, 2021) found no benefit over saline at 12 months in mild-to-moderate knee arthritis — so a weak response is real information, not a reason to buy more of the same shot.

Step 4 — Around six months

In patients whose first series helped, a booster PRP injection — with hyaluronic acid when your plan covers it — can extend the effect. In patients it didn't help, the conversation moves to the next rung of the ladder instead.

Step 5 — Ongoing care

The ideal orthobiologics patient has early-to-moderate arthritis or a soft-tissue injury, wants to stay active, and understands the honest goal: less pain, better function, more years out of your own joint — not regeneration miracles.

You may be a candidate if…

• Your knee or hip has mild-to-moderate arthritis — worn and painful, but not bone-on-bone
• You have a tendon, ligament, or meniscus problem that hasn't responded to a proper strengthening program
• You're an athlete protecting a joint after injury, or an active adult not ready for replacement
• You're medically better served by avoiding surgery, and comfortable with a cash-pay treatment whose response varies

It may be too soon or too late if…

• You haven't yet tried the covered basics — therapy, activity modification, cortisone or gel — that may work just as well
• Your joint is bone-on-bone; no biologic rebuilds absent cartilage, and replacement deserves an honest conversation
• The pain comes from a mechanical problem — a locked meniscus, a collapsed femoral head, instability — that needs its own fix
• You have an active infection, a bleeding disorder, or active cancer

A consultation with imaging tells you which rung of the ladder you're actually on.

Hawai‘i has no shortage of clinics selling "regenerative" shots. What they can't sell is judgment. A fellowship-trained hip & knee surgeon starts with the diagnosis — is this pain actually arthritis, or a meniscus tear, AVN, or an SI joint problem wearing a costume? — stages the joint honestly, delivers the biologic under image guidance, and tells you plainly when biologics would waste your money. When a joint is truly bone-on-bone, the kindest thing anyone can do is say so and explain what actually fixes it.

It's also why an orthopedic surgeon — rather than a chiropractor or a physician without musculoskeletal training — is the right person to deliver these treatments (how to choose a regenerative medicine specialist):

Orthobiologic injections are low-risk procedures — but no honest practice calls any procedure risk-free. Complications are rare and can include infection, bleeding, or nerve injury; a BMAC marrow draw adds a sore harvest site for a few days and, rarely, bleeding or nerve irritation at the back of the pelvis. Sterile technique and image-guided delivery keep those risks to a minimum, and because PRP, BMAC, and A2M are prepared from your own blood or bone marrow, there is no foreign substance for your body to react to. Prescription blood thinners are coordinated with your prescribing physician beforehand — never stopped on your own.

Most orthobiologic injections are not covered by insurance, which still classifies them as investigational. There are useful exceptions: some plans cover hyaluronic acid injections for a documented osteoarthritis diagnosis, and the consultation and imaging that decide candidacy are usually covered. Check what your plan covers — and let the office do the legwork:

Call (808) 439-6201 or book a consultation online. Dr. Morton sees joint-preservation patients at Pacific Bone & Joint in Honolulu (Ala Moana), West O‘ahu (Kunia), Hilo, and Kona — so treatment and follow-up stay close to home — and most new patients are seen within one to two weeks.

What to bring: a photo ID, your insurance card, a list of current medications (especially any blood thinner), and any prior X-rays or MRI. If your imaging was taken in Hawai‘i, the office can usually retrieve it electronically; new standing X-rays can be taken in clinic the same day. Managed-care and Medicaid/Quest plans may need a referral from your primary care physician for the consultation — the office checks before your visit.

At the visit, Dr. Morton examines the joint, reviews the imaging, and tells you which rung of the ladder you're on — a covered injection, a biologic series with a written quote, therapy, or a surgical conversation. When an in-person first visit isn't practical — a neighbor island without a nearby clinic, or a patient traveling from across the Pacific — a telehealth consultation can review your imaging and start the conversation, with any injection done in clinic.
