摘要：
A positioning apparatus for guiding resection of a patient tissue and guiding placement of a prosthetic implant component in a desired implant position with respect to the resected patient tissue and method of use are described. A locating block includes a mating surface contoured for mating contact with the patient tissue. A cutting plane indicator provides a physical indication of a desired cutting plane for the resection. A placement indicator is spaced apart from the locating block and includes a component-contacting feature. An elongate spacing arm is operative to space the placement indicator apart from the locating block. The spacing arm is configured to place the component-contacting feature of the placement indicator at a predetermined placement position in three-dimensional space relative to the patient tissue. The placement position predetermination is at least partially based upon pre-operative imaging of the patient tissue.
