Bipartite patella is a normal variation in ossification development. This variation is usually asymptomatic but can cause persistent and debilitating anterior knee pain with an injury. We report the case of a 56-year-old man complaining of persistent anterior left knee pain following trauma. Standard knee radiographs show a bilateral Bipartite Patella appearance, and magnetic resonance imaging shows discrete bony edema of the cancellous bone of the accessory bone and about the synchondrosis explaining the anterior knee pain, associated with a crack in the posterior compartment of the medial meniscus. Conservative care including medical treatment with non-steroidal anti-inflammatory drugs, physical therapy was used. Magnetic resonance imaging is the most valuable diagnostic tool for evaluating detailed morphologic and pathologic changes in patients with the bipartite patella.
