Embodiment Construction

[0016] Now refer to figure 1 and Figures 2A to 2D , we will describe a mode of implementation of the ligament 11 according to said invention, which is an open ring.

[0017] This example has many advantages: First, it is very easy to make. Additionally, due to the thin final diameter of the bundle, a small diameter tunnel needs to be drilled, which is clearly preferable in terms of surgery.

[0018] According to an essential characteristic, refer to figure 1 , the ring formed by the second intraosseous end portion 12' or the femoral end portion is open. Thus, the first intraosseous end portion 12 or the tibial end portion is composed of two cylindrical strands 12a, 12b.

[0019] The two intraosseous end portions 12, 12' are interconnected by an intraosseous intermediate portion 13 formed by two bundles 13a, 13b of professional wires. The professional wires of the intra-articular middle part 13 are free, whereas they are joined together at the intra-osseous ends 12, ...

Abstract

Prosthetic ligament (11) for replacing a natural articular ligament, comprising a first intraosseous end part (12), called the tibial end part, and a second intraosseous end part (12'), called the femoral end part, the two intraosseous end parts (12, 12') surrounding an intraarticular central part (13), characterized in that the first intraosseous end part (12) is in the form of two cylindrical strands (12a, 12b), and in that the second intraosseous end part (12') forms a loop connected to the first intraosseous end part (12) via the intraarticular central part (13), which is composed of at least two bundles of technical filaments, each of the bundles being connected to the first intraosseous end part (12) at one of its ends and to the second intraosseous end part (12') at the other of its ends.

Description

technical field [0001] The present invention relates to an artificial ligament designed to be placed in place by lateral fixation techniques, and to methods of preparing such a ligament. This ligament can be used in orthopedic surgery of the knee as a replacement for the anterior and posterior cruciate ligaments. Background technique [0002] A number of artificial ligaments are known which have been designed to replace articular ligaments. These include coiled and folded ligaments of ribbon-like fabrics woven or knitted from biocompatible materials so that the longitudinal specialized threads of the ligament are free from each other or otherwise interconnected. These known ligaments generally have the overall shape of an elongated cylinder comprising two outer intraosseous parts and a middle intraarticular part. Examples of such ligaments are likewise provided in French patents FR 2.755.846 and FR 2.688.690. [0003] Conventional surgical techniques for securing these ar...
