Research

Dr. Gross summarizes his study as follows:

Cleary my preference is an uncemented femoral component and most of my patients follow my recommendation. However, I still cement some femoral heads at the requestof patients who are not comfortable with the porous femoral option.

In summary:

♦ Fully porous femoral resurfacing components are now available in the US from Biomet.

♦ These components allow us to eliminate cement completely from the resurfacing procedure.

♦ No other companies are yet selling these in the US.

♦ Corin has had a partially porous femoral component available in Europe for several years.

♦ Virtually all clinical data on hip surface replacement to date is based on an uncemented acetabular component and a cemented femoral component (hybrid fixation).

♦ Corin data from England with a partially porous femoral components is equivalent to data with cemented femoral components at 1-3 years in over 600 patients.

♦ My limited 7 year data with a Corin HA nonporous uncemented femoral component is promising.

♦ It is not clear, if uncemented technology on the femur will be better or worse then cemented femoral components at this point.

♦ I perform either the traditional hybrid or the latest fully porous resurfacing as desired by the patient. My preference is the uncemented technique.
