The present invention relates to a medical implant for cartilage and/or bone repair at an articulating surface of a joint. The implant comprises a contoured implant body and at least one extending post. The implant body has an articulating surface configured to face the articulating part of the joint and a bone contact surface configured to face the bone structure of a joint, where the said articulating and bone contact surfaces face mutually opposite directions and said bone contact surface is provided with the extending post. A cartilage contact surface connects the articulating and the bone contact surfaces and is configured to contact the cartilage surrounding the implant body in a joint. The articulating surface has a layer that consists of titanium nitride (TiN) as the wear-resistant material. The cartilage contact surface has a coating that substantially consists of a material having chondrointegration properties.

Method of manufacturing an implant and an implant with two coatings

The present invention relates to a surgical kit, a saw guide and other related tools used in the osteotomy for temporary removal of a piece of a first bone structure to gain temporary access for treatment of defects of a second bone structure, as well as methods for designing and manufacturing said tools.

Tools for assisting in osteotomy procedures, and methods for designing and manufacturing osteotomy tools

A medical implant for cartilage repair at an articulating surface of a joint includes a contoured, substantially plate shaped, implant body and at least one extending post. The implant body has an articulate surface configured to face the articulating part of the joint and a bone contact surface configured to face the bone structure of a joint, where the articulate and bone contact surfaces face mutually opposite directions and the bone contact surface is provided with the extending post. A cartilage contact surface connects the articulate and the bone contact surfaces and is configured to contact the cartilage surrounding the implant body in a joint. The cartilage contact surface has a coating that substantially only includes a bioactive material.

Implant for cartilage repair

A surgical kit suitable for repair of articular surfaces in the talocrural joint, includes: a surgical implant having a cap with an outer surface conforming to a talus dome surface and an inner surface having a central implant anchoring peg extending perpendicularly from said inner surface, a hollow tubular shell suitable for correct pre-drilling for implantation of the surgical joint implant in the dome of the talus, and a saw guide conforming and fixable to the lower portion of the tibia and providing saw guide surfaces in at least one plane, suitable for osteotomy of a lower portion of a tibia to expose the dome of the talus.

Surgical kit for repair of articular surfaces in the talocrural joint including surgical saw guide

A surgical kit for cartilage repair at an articulating surface of a joint, including a medical implant and a set of tools. The medical implant includes a substantially plate shaped implant body having a predetermined cross-section that substantially corresponds to the area of the damaged cartilage. The set of tools includes a guide tool including a positioning body and a guide channel. The positioning body has a cartilage contact surface that has a shape and contour that is designed to correspond to and to fit the contour of the cartilage or subchondral bone in the joint in a predetermined area surrounding the site of diseased cartilage. The guide channel has a cross-sectional profile that is designed to correspond to the cross-section of the plate shaped implant body. Additional tools in the set of tools have a cross-sectional profile that is designed to correspond to the cross-sectional profile of the guide channel.

Surgical kit for cartilage repair comprising implant and a set of tools

A manufacturing system for a surgical kit includes surgical tools and an implant for cartilage repair in an articulating surface of a joint. The design system includes the basic blocks of: I. Receiving design parameters for a surgical kit in a computer controlled manufacturing system, the design parameters for the surgical kit representing a model for a medical implant and a guide tool for implanting the implant; II. Manufacturing a medical implant dependent on the design parameters; and III. Manufacturing a guide tool for implanting the implant dependent on design parameters.
