Sowa B, et al. - Researchers assessed the importance of the subchondral bone layer and the influence of the design of the glenoid component. In order to diminish the micromotions of the glenoid component, conservative reaming proved important. A help in the preservation of the subchondral bone layer without sacrificing proper implant seating could be provided by the implantation of a glenoid component that matches with the bony underlying glenoid.
