Abstract: Provided herein is an arc-shaped meniscus prosthesis with a first end having a first fastening part for securing the first end to a bone surface and a second end having a second fastening part for securing the second end to a bone surface. A curved intermediate section connects the first end and the second end. The curved intermediate section is made of a single first biocompatible, non-resorbable material that has a tensile modulus of at most 160 MPa. The first material is isotropic with regard to the tensile modulus and the intermediate section is a monolithic piece of the first material.

Abstract: A prosthesis for a mammal comprises a prosthesis body (302) with a dorsal surface (311) and a ventral surface (312) shaped to fit in a joint between a tibia and a femur so that the dorsal surface faces a distal end of the femur and the ventral surface faces a proximal end of the tibia. At least one fixation element (303) is provided for fixing the prosthesis body (302) to the tibia (150), wherein the dorsal surface (311) is inclined in a dorsal direction towards a caudal edge of the prosthesis body, to stabilize the femur.

Abstract: A prosthesis assembly (100) for orthopaedic implantation comprises a prosthesis body (110) and an attachment portion (112) coupled to the prosthesis body (110) for attaching the prosthesis assembly (100) to a bone by way of a bone anchor (120) or other fixating means. The attachment portion (112) comprises an opening (130) having a receiving portion (132) with a first cross-sectional transverse width and a retaining portion (134) extending from the receiving portion (132), the retaining portion (134) having a second cross-sectional transverse width, which is less than the first cross-sectional transverse width. A system comprising the prosthesis assembly (100) includes a bone anchor (120) having a fastening member (124) for engaging the opening (130) and a stem (122) for securing to the bone.

Abstract: A meniscus prosthesis includes a core made of a first biocompatible, non-resorbable material having a first tensile modulus. The core includes an arc-shaped body having: a first end having a first through-hole; a second end having a second through-hole; a curved intermediate section connecting the first end and the second end; a first surface configured to face a first interior surface of the joint during use and a second surface configured to face a second interior surface of the joint during use, an inner edge and an outer edge. The core comprises a transverse cross-section in which the width is greater than the height along the length of the core. A cushioning material surrounds the intermediate section of the core, the cushioning material being made of a second biocompatible, non-resorbable material having a second tensile modulus, which is lower than a tensile modulus of the first material.

Abstract: A joint prosthesis assembly, includes a joint prosthesis body (1) made of a first biocompatible non-resorbable material and an anchoring element (2-5) made of a second biocompatible non-resorbable material. The anchoring element (2-5) is arranged to allow rotation of an end portion of the joint prosthesis body (1) with respect to the anchoring element (2-5) when in situ.
