Abstract: Suprapatellar systems, system components, and methods of operating on a tibial fracture of a patient are disclosed. A method can include making an incision proximal to a patella of a knee joint, forming an operation space, and inserting a portion of a retractor in the operation space to define an entry canal. The retractor can be inserted in a low profile configuration and, once positioned as desired by a surgeon, expanded to a high profile configuration. Expansion of the retractor can expand the operation space in at least one of an anterior-posterior direction or a medial-lateral direction and can increase a diameter of the entry canal. The method can further include inserting a trocar, having at least one guide hole, in the entry canal and guiding a guide pin through the at least one guide hole and into a tibia.
