Abstract: A prosthetic socket component for articulating anatomical joints includes a shell member for being affixed to a first bone of the joint and a liner to be received in a cavity of the shell member through an opening in the shell member communicating with the cavity. The cavity has a longitudinal axis that is angularly offset from a longitudinal axis of the shell member, and the liner is rotatable relative to the shell member about the cavity axis to change the size of an angle made by a socket opening in the liner with the cavity opening. A method of implanting a prosthetic socket component includes the step of aligning a portion of the liner with one of a plurality of portions of the shell member to position the socket opening a predetermined angular distance from the cavity opening. An introducer for the prosthetic socket component includes a handle and a head for being received in the cavity with a longitudinal axis of the handle aligned with the shell member longitudinal axis.
