Embodiment Construction

[0027] The specific technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] An artificial total knee replacement prosthesis capable of reconstructing the anterior cruciate ligament of the present invention includes a liner 1 and a tibial plateau support 2, Figure 1 to Figure 4 are the structural schematic diagrams of the liner 1 and the tibial plateau holder 2 respectively.

[0029] Such as figure 1 , figure 2 As shown, the liner 1 is made of a low friction, high density, low wear plastic, such as ultra high molecular weight polyethylene or other resins known to be suitable for these applications. The liner 1 is symmetrical with respect to the center plane vertically and along the front-to-back direction, and its shape is ellipse, rectangle with rounded corners, etc. The liner of the technical solution of the present invention is an ellipse with a rear groove. Liner 1 includes an elliptical pla...

Abstract

The present invention is one kind of artificial total knee replacement prosthesis of rebuildable anterior cruciate ligament, which comprises tibia plant holder piece and pad; tibia plant holder piece comprises horizontal plant and member bar fastened together, top surface of pad has double horizontal spaced spherical concave surface to receive separated one part of femur condyle. Designing a pore path both on pad and tibia plant holder piece, which penetrate separated the horizontal plants of pad and tibia plant holder piece and connect to each other, makes anterior cruciate ligament can cross the pore path and be fixed of two ends separated femur external malleolus and tibia down horizontal plant of tibia plant holder piece, realizes rebuilding of anterior cruciate ligament in artificial total knee replacement.

Description

technical field [0001] The invention relates to an artificial total knee replacement prosthesis, in particular to an artificial total knee replacement prosthesis capable of reconstructing the anterior cruciate ligament. Background technique [0002] The artificial joint is one of the most important advances in the orthopedic field in the 20th century, and it is also the most mature and successful organ transplant in tissue and organ transplantation; Walking like a normal person greatly improves the quality of life. As a mature treatment method, it has been widely used at home and abroad. At present, artificial joint replacement has become the ultimate treatment for severe bone and joint diseases, and is known as an important milestone in the development history of orthopedics in the 20th century. [0003] The development of total knee replacement (TKR) surgery has also achieved great success, but in a long-term follow-up study, the complications of total knee replacement su...
