A method and instrumentation for performing a patellofemoral arthroplasty orthopaedic procedure includes coupling an anterior cutting block to a femur of a patient such that the cutting block references local anatomy of the femur. The anterior cutting block is used to perform a number of bone cuts to establish a trochlear cavity in the femur. The trochlear cavity is formed such that a trochlear prosthesis may be inset into the cavity and substantially flush with the surrounding cartilage. A finishing burring guide and burr bit may be used to detail the shape and/or size of the trochlear cavity. Additionally, a trochlear drill guide may be used to facilitate establishing peg holes in the patient's femur to receive corresponding pegs of the trochlear prosthesis.
