A method and apparatus are provided for replacing the articular surface of the ball of a ball and socket joint. The method comprises the steps of establishing the location of the intramedullary canal adjacent the ball of the joint, and placing a locating component, such as a reamer or broach, in the canal. The method further comprises sizing the articular surface of the ball to be replaced, placing on the component a resecting guide having an opening therein for receiving the component and a complementary surface to the articular surface of the ball to be replaced, rotating the component in a manner determined by the opening in the resecting guide, and resecting the ball in a manner determined by the orientation of the resecting guide.
