Abstract

The present invention relates to a method and instrumentation for gaining access to areas in and around joints for treatment and to provide new implants and instrumentation adapted for the new method. In a transosseous core approach of the present invention, the joint is entered through a pathway provided in a portion of a joint bone. Such pathway is preferably made by taking out a bone core from the bone in or adjacent to the joint, wherever possible without substantially compromising physical integrity and physiological viability of the joint. Typically the main route for the transosseous core approach traverses through a more-accessible bone of the joint which can be aligned with a less-accessible bone of the joint in order to facilitate treatment of articular surfaces and/or other structures in the joint. The transosseous pathway into the joint is preferably provided by novel surgical instruments such as a core cutter, cartilage punch, hemostatic device, and retractable axial/transaxial cutting device. Implants modules are also provided which can be inserted into the joint through the transosseous pathway and assembled in situ inside the joint to form an implant assembly.
