A system for preparing a trochlear region of a resected femur is disclosed. The system includes a reamer guide (20, 70) and a reamer (30, 40). The reamer guide (20, 70) has a first arcuate portion (21, 71), a second arcuate portion (23, 73), a wall (25, 75), a protrusion (27, 77) connected to the wall, a leg (28, 74, 78) connected to one of the first or second arcuate portion (21, 23, 71, 73), and a distal tip portion (26, 76) connected to the leg (28, 74, 78). The reamer (30, 40) is adapted to rotatably connect to the distal tip portion (26, 76), and the reamer has a first end portion (32, 47), a second end portion (36, 48), and one or more flutes (38, 44).
