Orthopedic injections

Injection options without guessing at the pain source.

Injections can be useful, but only when we know what we are treating. Knee pain, hip pain, tendon pain, arthritis, and referred pain can feel similar and need different plans.

How the visit works

You should leave with a clearer plan than when you arrived.

01

Tell the story

Dr. Morton starts with what happened, what has changed, what you have already tried, and what you need your body to do again.

02

Look at the source

Your exam and imaging help separate arthritis, injury, implant problems, referred pain, and other causes that can feel similar.

03

Choose the next step

The plan may be therapy, bracing, injections, orthobiologics, arthroscopy, robotic surgery, revision workup, or a clear reason to wait.

Before you book

The first visit is better when the story is organized.

Joint Replacement Hawaii has always asked practical questions before the appointment because the details matter: what hurts, where it hurts, what you have tried, and what life activity you want back.

01

What are you having trouble with?

Getting in and out of a car
Getting up from a chair
Stairs
Walking long distances
Pain at night
Exercise, sports, or work

02

What are you noticing?

Swelling
Instability or giving way
Stiffness or limited motion
Catching or locking
Grinding
Difficulty bearing weight

03

What have you already tried?

Physical therapy
Brace, cane, walker, or crutches
Steroid or gel injections
PRP or BMAC questions
NSAIDs or Tylenol
Prior arthroscopy or surgery

Before you decide

The conversation I want patients to understand.

01

When injections help

An injection may calm inflammation, help with pain, buy time, or help confirm where pain is coming from.

02

What we compare

We compare steroid, gel, PRP, BMAC, therapy, bracing, medications, arthroscopy, replacement, or waiting when appropriate.

03

When injections are not enough

Advanced arthritis, deformity, locking, instability, infection concern, or a painful implant may need a different workup.

How I think through the recommendation

The decision should be explained, not handed to you.

Patients should know what would make us wait, what would make treatment reasonable, what might require more testing, and what changes recovery planning.

01

What may make us wait

  • Diagnosis is not clear enough for an injection
  • Symptoms are improving with simpler care
  • Cost, coverage, or expectations need more discussion

02

What may make PRP or BMAC reasonable

  • Mild or moderate arthritis with realistic goals
  • Tendon, ligament, or joint-preservation problem fits
  • The patient understands limits and aftercare

03

What may mean more tests

  • X-rays are needed to stage arthritis
  • MRI may be needed for meniscus, tendon, or cartilage questions
  • Severe deformity or instability changes the conversation

04

What changes aftercare

  • Activity modification after injection
  • Response tracking over weeks to months
  • Clear plan if symptoms do not improve

Injection decision guide

Start with what we are treating, then choose the injection.

BMAC, PRP, gel, steroid injections, braces, therapy, arthroscopy, and replacement are not interchangeable. I explain the options after we know the target and the severity of the problem.

Think about 01

Name the target

Tendon pain, mild arthritis, bone-on-bone arthritis, meniscus injury, and referred pain all need different conversations.

Think about 02

Know the tradeoffs

Cost, insurance, timing, aftercare, and expected response are part of the decision, especially for PRP and BMAC.

Think about 03

Avoid miracle claims

I do not promise cartilage regrowth. If an injection is unlikely to help, I want patients to hear that clearly.

For informed patients

The details matter, especially when the decision is not simple.

If you are comparing surgeons, robotics, revision care, injections, or recovery plans, these are the questions I want you to feel comfortable asking.

01

Candidacy first

PRP and BMAC depend on diagnosis, arthritis severity, alignment, tissue quality, and expectations.

Imaging reviewCost and coverageAftercare plan

02

No miracle claims

The visit should avoid promises about cartilage regrowth and compare injections with therapy, bracing, arthroscopy, replacement, or waiting.

Honest limitsOptions comparedFollow-up if symptoms persist

Patient words

The trust signal should match the decision.

Patients are looking for listening, clear explanations, office kindness, and a plan that makes sense for their specific problem.

Patient trust

PRP and BMAC deserve honest counseling.

Some patients are good candidates. Some are not. The conversation starts with diagnosis, imaging, arthritis severity, cost, and expectations.

01

BMAC and PRP education

02

Candidacy before treatment

03

No miracle claims or guaranteed cartilage-regrowth language

You may be ready to schedule if

Arthritis flare or activity-limiting pain
Trying to delay surgery when reasonable
You want to compare steroid, gel, PRP, or BMAC
Prior injection wore off
You need to understand timing before possible surgery

Why patients choose this practice

PRP and BMAC are discussed only after diagnosis and imaging review
Regenerative options are explained without cartilage-regrowth promises
Surgery, therapy, bracing, injections, and waiting can be compared honestly

Older patients and caregivers

Older patients and caregivers deserve a clear plan too.

Safety, medications, stairs, rides, hearing, memory, home help, and caregiver questions can change the recommendation and the recovery plan.

01

Who should come with you

Bring the person who helps with medications, rides, meals, stairs, wound checks, or remembering instructions. A second set of ears helps.

02

How to plan home safety

Think about loose rugs, bathroom setup, stairs, lighting, pets, walking aids, shower safety, and where you will sleep the first few nights.

03

When to call the office

Call for worsening wound redness, drainage, fever, severe swelling, a fall, medication confusion, or symptoms that do not match your instructions.

04

When not to wait

Chest pain, shortness of breath, fainting, stroke-like symptoms, major deformity, or dangerous symptoms need emergency care.

Helpful to bring

X-rays, MRI, CT scans, or reports if you already have them
Where the pain starts, where it travels, and what it stops you from doing
Prior injections, therapy, medications, braces, or operations
Your goals for work, walking, golf, hiking, sports, travel, and recovery

Make the visit count

Bring the story, not just the scan.

Imaging helps, but the story matters too: what changed, what you tried, what failed, and what life you want back. This is especially important for revision opinions, prior surgery, and neighbor island travel.

Recovery preview

Prepare for BMAC or PRP aftercare

Orthobiologic aftercare should explain activity changes, response tracking, realistic expectations, and follow-up.

Patient questions

Questions I hear in the office.

Which injection is best?

There is no universal best injection. The right option depends on diagnosis, imaging, prior treatments, health history, and goals.

Can injections delay surgery?

Sometimes they can help manage symptoms, but timing depends on severity, function, and whether surgery is already the more realistic conversation.

Can I get an injection before joint replacement?

Injection timing before surgery can matter. Ask before receiving injections near a possible surgery date.

Mahalo

You do not have to figure this out alone.

If pain, injury, arthritis, or an old implant is keeping you from life, bring your questions. Dr. Morton and the team will help you understand the problem and the next step.

Written for patients by the practice

Orthopedic guidance should be clear enough to help you make a real decision.

Dr. Paul Norio Morton created Joint Replacement Hawaii to help patients understand hip pain, knee pain, arthritis, sports injuries, robotic joint replacement, revision surgery, injections, and recovery before they come in for a visit.

Recognition

Awards, focused training, and Hawaii-specific care planning help patients compare trust before they schedule.
