Abstract: A joint prosthesis for attachment to a bone of a patient, comprising an anchor with a head surface and a stem for attachment to an end of the bone, the head surface having an anatomically accurate shape.

Abstract: A bioreactor generates load-bearing cartilaginous or fibro-cartilaginous tissue by applying hydrostatic pressure and/or deformational loading to scaffolds seeded with chondrocytes and/or other cells. A scaffold may be shaped to reproduce the geometry of all or part of a load bearing articular surface or defect as acquired from a database or patient-specific geometry data. Optionally a scaffold can be attached to a substrate which promotes integration of this tissue construct with the underlying bone of the patient joint. In the bioreactor, ambient hydrostatic pressure and scaffold deformational loading can be prescribed with any desired waveform, using magnitudes which prevail in diarthrodial joints. The loading platen, permeable or impermeable, may conform to all or part of the scaffold surfaces.

Abstract: The present invention relates to a method of generating a three dimensional representation of one or more anatomical joints, wherein the representation comprises two or more movable bodies and one or more links, comprising the steps of inputting anatomically representative data of two or more movable bodies of the selected joint or joints; selecting one or more link types responsive to the representative data of the bodies; selecting link characteristics responsive to each selected link type; generating an equilibrium condition responsive to interaction between the bodies and the links; and displaying a three dimensional representation of the selected joint or joints responsive to the data generated from the equilibrium condition of the anatomical joint or joints. The present invention further relates to a system for generating a three dimensional representation of one or more anatomical joints, and a method of planning surgery of one or more anatomical joints.
