On the table
What it does, the lengths it comes in and what experienced techs know about it.
What it’s for
The new ligament in an ACL reconstruction when the patient's own tendon is not used. It is opened on the surgeon's call, thawed and prepared on the back table (trimmed, sized through sizing tubes and stitched at the ends), then pulled through the bone tunnels and fixed with screws or buttons.
Lengths and variants
Each graftGRAFTTissue or a man-made material moved into place in surgery to replace or repair a damaged part.Full entry is labeled with its measured size. In one tissue bank's range the anterior tibialis is 22 to 38 cm long and 6 to 12 mm wide; the label also gives the folded diameter, the smallest tunnel the doubled tendon fits through. Small folded-diameter grafts (5 to 7.5 mm) and frozen or freeze-dried forms are offered.
