There is disclosed a prosthetic ligament (20) made of woven implantable material and which can be introduced into a passage (11) formed in a pair of adjoining bones (12, 13) of a bone joint, there being enlarged entrances (14) at each end of passage (11) to receive bone plugs (14a) for closing the entrances after the ligament has been introduced into the passage and the entrances. The ligament (20, 30) comprises a main tubular portion (21) to be located in the passage (11) and having its axis extending generally longitudinally of the ligament, and end portions (25) each intended to be located in a respective entrance (14) and to project therefrom for securement to the respective bone (12, 13) by mechanical fixation. At least one of the end portions (25) comprises a tubular portion (26) which extends transversely of the longitudinal axis and which is open at each end so as to receive an elongate anchoring element (a cross piece of a staple 28 or an anchoring bar 31) of a mechanical fixation arrangement which is operative to make a mechanical fixation of the end portion to the respective bone, and there is also provided a strengthened section (27) in the form of a dense weave section which is adjacent to the transverse tubular portion (26) and which can therefore withstand tensile load which may be applied in use to the ligament. |
