01 ABOUT

What Is Osteonecrosis?

A condition in which blood flow to the top of the thighbone, inside the hip joint, decreases
and part of the bone dies.

The femoral head is the rounded part of the bone that bears your body weight. If the dead bone collapses, it can lead to hip pain and difficulty walking.

Treatment options vary with the extent and location of the necrosis and the condition of the bone. The first step is to assess your condition.

How It's Diagnosed and Treated

02 SYMPTOMS

Does any of this
sound familiar?

For anyone dealing with pain in the knee, hip, foot, ankle or other joints, or with questions about treatment.

Your hip or other joints hurt
every time you walk or stand up
Pain persists despite
ongoing injections or treatment
An MRI has shown bone marrow lesions (BML)
or osteonecrosis
You'd like to discuss options
other than joint replacement
Work or family makes it hard
to take time off for a hospital stay
You want advice so you can
keep up your sports or hobbies

These symptoms alone are not enough to diagnose osteonecrosis of the femoral head. The cause is determined through examination and tests.

03 TREATMENT

Treatment options that fit
each patient's condition.

Which treatment is right for you depends on your condition.
We explain a treatment plan that takes into account your examination and test results, your wishes and your lifestyle.

01Joint Treatment

Joint Injections

We offer joint treatments such as stem cell therapy and PRP (platelet-rich plasma). The doctor decides at your examination which areas and symptoms can be treated and whether a treatment is right for you.

  • For the knee, hip, foot, ankle and other joints
  • Culturing the cells for stem cell therapy takes about a month
  • Regenerative medicine is self-pay (not covered by insurance)

02Depends on Your Condition

Same-Day Surgery

We perform same-day surgery for osteonecrosis of the femoral head, osteonecrosis of the knee, foot or ankle, and osteoarthritis. If a hospital stay would be difficult for you, please talk to us.

  • Suitability is assessed through examination, imaging and other tests
  • May be combined with joint injections
  • Referral to partner hospitals when needed
About Same-Day Surgery

Results and progress vary from person to person. In some cases, another treatment, such as joint replacement surgery, may be appropriate. Before any treatment, we explain its cost, its risks and how many visits to expect.

First Visit: Steps and What to Bring

FAQ

Frequently Asked Questions

Can I see the doctor without MRI images?

Yes. You don't have to bring MRI images, but if you have images or test results, please bring them. Not having to bring images doesn't mean an MRI is unnecessary for diagnosis. The doctor decides which tests you need.

What is the difference between a free phone consultation and an in-person visit?

In a free phone consultation, the medical director asks about your condition and explains the treatment options that may be available. At an in-person visit, we do X-rays, ultrasound, blood tests and other tests as needed, and the doctor decides on a treatment plan. A phone consultation alone cannot confirm whether a treatment is suitable for you.

Is my appointment confirmed when I send a request online?

No. The online form sends us your request and preferred times. Our staff will then call you within two clinic days (not counting days the clinic is closed) to arrange the date and time, and your appointment is confirmed after that.

Can I discuss options other than joint replacement?

Yes. We listen to your wishes and explain the options based on your examination and test results. Depending on your condition, joint replacement surgery or another treatment may be appropriate, and we refer you to a partner hospital when needed.

Can I see the doctor on Sundays?

Yes, the clinic sees patients on Sundays. However, it may be closed on some Sundays or for part of the day, so please ask when you make your appointment.
