Procedure for Harvesting of Crude BTB for Patellar Tendon Tibial Donor
[0036]A BTB was harvested according to the following procedure:
[0037]1. Using blunt and sharp dissection remove the three layers of connective tissue from the anterior portion of the tendon.
[0038]2. Using scalpel or scissors cut along the medial and lateral borders of the tendon. Use the scissors to bluntly dissect under the tendon to separate it from the fat layer.
[0039]3. Cut around the Patellar block to separate it form the proximal tibia and distal femur. Leave approximately 4 cm of quadriceps tendon attached to the patellar if required. If no quadriceps tendon attachment is specified then remove quadriceps from patellar completely using sharp dissection.
[0040]4. Pull tendon away from capsule and remove all excess adipose tissue to the point of tibial insertion.
[0041]5. With a saw make a transverse cut through approximately the tibial tuberosity about 30 mm from the tendon insertion point. Make a similar cut a...

Procedure for Forming Patellar Tendons with Preshaped Dowels for Patellar Tendon Tibial Donor
[0048]A BTB was harvested according to the following procedure:
[0049]1. Using blunt and sharp dissection remove the three layers of connective tissue from the anterior portion of the tendon.
[0050]2. Using a scalpel or scissors cut along the medial and lateral borders of the tendon to separate it from the fat layer.
[0051]3. Cut around the Patellar block to separate it from the proximal tibia and distal femur.
[0052]4. Pull tendon away from capsule and remove all excess adipose tissue to the point of tibial insertion.
[0053]5. With a saw make a transverse cut through the tibial tuberosity about 30 mm from the tendon insertion point. Make a similar cut just proximal to the insertion point removing the tibial plateau. Make another cut across the coronal plane 20-30 mm posterior from the insertion point.
[0054]6. With a saw square the sides of the tibia bone block.
[0055]7. With a saw cut and square ...
