However, when revision, radiographic evidence of a loose component, and recurrence of pain were all used as determinants of failure, the cumulative rate of success was only 75percentnt.
There was 99% implant survival; 1 patient required revision of a loose tibial component after a motor vehicle accident.
Hofmann et al. [ 24] reported 98% survival of TKAs performed with a similar technique with minimum 5-year followup, with no revisions due to a loose tibial component.
During the ten-year period of follow-up, twelve of the original group of patients had a revision of a loose tibial component.
Furthermore, we have shown that its low recalcitrance arises from several key features such as: a loose non-cellulosic wall component structure, high enzyme accessibility, good hydrophilicity, and less ordered crystalline structure.
This patient also had a loose tibial component and the only loose femoral component in the series.
The third research question addresses the question of how much motion is present at the stem-cement and cement-bone interfaces for radiographically well-fixed components as compared to loose components.
Radiographs demonstrated a loose femoral component and the stem was found to be loose at the time of revision.
At the ten-year evaluation, six of the sixty-one knees that had not been revised had a loose tibial component.
One patient had a loose patellar component, which had avulsed from the patella within the first few weeks after the operation.
A vision of culture not as a loose assemblage of disparate fragments but as an organic unity, each component, like the organs in a body, carefully adapted to occupy a particular place, each part essential to the functioning of the whole.
