Abstract: A design method for designing a guide tool including a guide channel for use during cartilage repair in a joint is disclosed. The design method includes: selecting a direction along a joint axis indicating placement of the guide tool in the joint; and placing a positioning mark on the guide tool. The positioning mark is designed to be aligned with the center of said guide channel on a determined joint axis direction and thereby indicating a placement direction of the guide tool in relation to the selected joint axis during use of the guide tool. A design method of insert tools and/or an implant comprising positioning marks and also the guide tool, implant and insert tools designed using this method are also disclosed.

Abstract: A guide tool adapted for removal of damage cartilage and bone and adapted for guiding insert tools during repair of diseased cartilage at an articulating surface of a joint is disclosed. The guide tool includes a guide base having a positioning body and a guide body protruding from the guide base. The guide body includes a height adjustment device and a guide channel with a length. The guide channel extends throughout the guide body and through the height adjustment device with one opening on a cartilage contact surface of the positioning body and one opening on the top of the height adjustment device. The guide body includes a height adjustment device being arranged to enable stepwise adjustment of the length.
