Abstract

The invention relates to a bone-patellar tendon-bone graft structure and a preparation method thereof. The bone-patellar tendon-bone graft structure comprises a patellar cylinder, a patellar ligament,a tibia cylinder and a cone-shaped body, wherein the patellar cylinder and the tibia cylinder are connected to two ends of the patellar ligament through natural biological tissue, and the cone-shapedbody is formed by polishing one end of the patellar cylinder and one end of the tibia cylinder. The tips of the two conical bodies face the same direction; two circular holes with the diameter of 2 mm are respectively formed in the one-third boundary of each of the patella cylinder and the tibia cylinder, the circular holes penetrate through the patella cylinder and the tibia cylinder, and No. IImacromolecule non-absorbable braided wires penetrate through the circular holes. The bone-patellar tendon-bone graft structure has the advantage that reliable and effective transplantation and repairof fractured ligaments such as knee joint cruciate ligaments can be achieved.

Description

technical field [0001] The invention relates to the technical field of transplant surgery, in particular to a structure of a bone-patellar tendon-bone graft and a preparation method thereof. Background technique [0002] The cruciate ligament of the knee joint is an important stable structure of the knee joint. It is hinged between the intercondylar fossa of the femur and the intercondylar eminence of the tibia, preventing the tibia from shifting forward and backward along the femur. The cruciate ligament of the knee can be divided into two front and rear parts. The anterior cruciate ligament starts from the medial surface of the lateral femoral condyle, obliquely forward and downward, and ends at the front of the intercondylar eminence of the tibia and the front corner of the medial and lateral meniscus; the posterior cruciate ligament It originates from the lateral surface of the medial femoral condyle, goes obliquely posteriorly and inferiorly, and inserts on the posterio...
