Does Lateral Meniscal Allograft Transplantation Using the Keyhole Technique Restore the Anatomic Location of the Native Lateral Meniscus?
When comparing the position of the horns preoperatively and postoperatively, both horns showed mean relative postoperative positional changes of<5% of relative values and<5 mm of absolute values in both the coronal and sagittal planes. The keyhole technique in lateral MAT can reconstruct the lateral meniscus close to its native anatomic position by avoiding displacement of>5 mm in both the coronal and sagittal planes.
The serum samples from elderly subjects possessed a relatively high incidence of anti-basement membrane zone antibodies detectable with guinea pig esophagus as substrate. This observation of a specific immune defect in elderly individuals might explain why they are more susceptible to developing bullous pemphigoid.
