FAQ


What do you see as the advantages of resurfacing over Total Hip Replacement (THR)?

There is better functional performance with hip resurfacing. There is also a shorter recovery time with hip resurfacing, and it preserves bone for future need.

Is there anything I will not be allowed to do after my hip resurfacing procedure?

Not really. We have a number of professional athletes from a variety of different sports (skiing, tennis, golf, marathon running).

What would be my “window of opportunity” time frame for having hip resurfacing?

A hip resurfacing procedure can happen anytime symptoms warrant. Patients need to have resurfacing procedures performed while their bone remains healthy.

Is hip resurfacing new?

No, but it has greatly improved as the result of better instruments, implants and knowledge.

My orthopedic surgeon does not recommend hip resurfacing. Why?

Hip resurfacing is more difficult to perform and special training is required. It also takes longer and we do not charge more for the procedure. Most surgeons find total hip replacement quite satisfactory.

Do you see an increased risk of loosening of the cup component due to bone stock, and would that be the same for resurfacing as for total hip replacement?

There are more options for cup fixation with total hip replacement although the risk of loosening should be minimal with resurfacing.

Are there issues for resurfacing due to leg length?

Leg length is not addressed with the resurfacing procedure. It is very unusual for patients to have a significant leg length issue after resurfacing. Patients often feel the leg is longer at first since the wear of the joint results in gradual shortening over the proceeding months or years. By month seven most patients do not feel there is a difference in their leg lengths.

How long does an average resurfacing procedure take?

Usually between one to two hours.

With hip dysplasia, do you anticipate any need for bone grafting or screw fixation in the cup component?

We have the ability to perform both if necessary.

Do you use spinal or general anesthesia resurfacing surgery?

The surgery can be done with either anesthetic. The choice of anesthesia is generally decided by the patient and the anesthesiologist. Most patients prefer a spinal anesthetic with sedation that has them asleep during the procedure.

Which incision approach would you use for a case such as mine?

Either a posterior or anterior approach can be used. Patients seem to recover faster with the posterior approach.

What do you use to close the incision?

Usually intradermal sutures (they don’t need to be removed).

Will there be a need for banking my own blood, or do you use a blood salvaging technique?

Under normal circumstances blood transfusions are not necessary. We do
not need to save or pre-donate blood.

Do you anticipate any post-op weight-bearing restrictions?

No.

What are your other post-op restrictions and for how long?

Limit flexion to 90 degrees for one month.

What are the statistics of getting a post-operative infection at the hospital?

Less than a 1% chance.

Is there any chance I could come out of a surgery with a Total Hip Replacement rather than a resurfacing?

This is not at all likely (less than 1 in a thousand).

Is there an increased risk of AVN with a femoral head deformity?

Yes, there is still a small risk.

Is there a risk of dislocation?

Yes, but this does not reach a percentage point as a risk. The risk is less than with total hip replacement.

Is there a risk of nerve damage?

Yes. 1%

Are there any unusual risks or complications as compared with THR?

Yes. Component positioning is more difficult with resurfacing.

How long would you anticipate a resurfacing to last?

The implants typically do not wear out. The main concern is the bone.

Do you see a possibility of any unusual device wear or load issues?

No.

Should I go out of the country for hip resurfacing?

No. Hip resurfacing can be done here. We are concerned about the Americans that go abroad, especially because patients that go abroad do not always receive accurate follow-up care.
