ABSTRACT:
A prosthesis, such as a ligament or tendon prosthesis, comprises a low elastic modulus load bearing element (1) to which are attached a plurality of fine filaments (3) having a higher elastic modulus. The arrangement is such that the fine filaments are unstressed unless the load on the prosthesis exceeds a predetermined value, thus simulating the mechanical response of native collagenous tissue. The fine filaments, which are preferably of polyester, are arranged to allow ingrowth of fresh connective tissue.
