ACL reconstruction

ACL reconstruction and knee stability, explained clearly.

If your knee gives way, the question is not only what the MRI says. The question is whether the knee is stable enough for the life, work, and sports you want back. I look at the injury, the exam, the meniscus, the cartilage, and your goals before talking about surgery.

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 I usually see patients

Most ACL patients remember the moment: a twist, a pop, swelling, or a knee that no longer feels safe. Others come in after an MRI and want to know whether the tear actually needs reconstruction.

02

What we look at together

We review motion, swelling, the stability exam, MRI findings, meniscus or cartilage injury, sport goals, work needs, and whether the knee is giving way in real life.

03

Your options

Some patients can start with rehab, bracing, and careful activity changes. Others need reconstruction because the knee remains unstable or because their work or sport requires a stable pivoting knee.

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

  • Knee is stable enough for nonoperative rehab
  • Swelling and motion need to calm down before surgery
  • Activity goals do not require reconstruction

02

What may make reconstruction reasonable

  • Repeated giving-way episodes
  • Pivoting sport or work demands
  • Meniscus or cartilage protection is a major concern

03

What may mean more tests

  • MRI does not explain symptoms
  • Meniscus, cartilage, MCL, or bone bruise questions
  • Growth plate or prior surgery concerns

04

What changes recovery planning

  • Graft choice and associated repairs
  • School, sport, work, and brace needs
  • Return-to-sport testing and confidence

ACL decision guide

The MRI matters, but the real question is whether the knee is trustworthy.

ACL decisions depend on instability, sport goals, work needs, meniscus injury, cartilage damage, and how much rehab the patient can commit to.

Think about 01

Start with motion and swelling

Many patients need to calm the knee down, restore motion, and understand the injury before surgery is scheduled.

Think about 02

Decide if stability is enough

If the knee keeps giving way, or if pivoting sports are important, reconstruction may become the better conversation.

Think about 03

Plan the comeback

Return to sport depends on strength, balance, confidence, motion, swelling control, and time. It is not just a calendar date.

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

MRI plus stability

An ACL decision is not only an MRI finding. Instability, sport, work, meniscus, and confidence matter.

02

Recovery is the treatment

Surgery is one day. Rehab, swelling control, strength, and return testing drive the long-term result.

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

Sports knee patients want their confidence back.

ACL and meniscus care is about more than the MRI. It is about stability, swelling, mechanical symptoms, activity goals, and a recovery plan the patient can follow.

03

Return-to-sport and return-to-work milestones

You may be ready to schedule if

A pop or pivot injury followed by swelling
The knee gives way or feels untrustworthy
MRI concern for ACL tear
Meniscus or cartilage injury may also be present
You need a real return-to-sport or return-to-work plan

Why patients choose this practice

Sports knee, meniscus, ACL, injection, and recovery decisions are connected
MRI findings are matched to the exam and the way the knee behaves
Return-to-work, return-to-sport, and long-term joint protection are discussed together

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 ACL recovery

ACL recovery needs swelling control, motion, strength phases, graft protection, and return-to-sport criteria.

Patient questions

Questions I hear in the office.

Does every ACL tear need surgery?

No. The decision depends on instability, activity goals, age, associated meniscus or cartilage injuries, and how the knee behaves after rehab.

Can I wait before surgery?

Sometimes. Many patients need swelling and motion to improve first. The risk is repeated giving-way episodes, especially if they damage the meniscus or cartilage.

How long is ACL recovery?

ACL recovery is measured in months, not weeks. Strength, motion, swelling, confidence, and return-to-sport testing matter before going back.

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.
