A tool intended to facilitate the trimming of the stem of a patellar prosthesis to adapt the length of the stem to fit differing cross-sectional thickness of a human patella is disclosed. The trimming tool includes a seat area for receiving the prosthesis and a cap member for securing the prothesis in the seat. The cap area includes an aperture therethrough which exposes a specific length of stem for trimming. A cutting guide on the cap member ensures that the stem is cut in a perpendicular orientation to the centerline axis of the prosthesis.
