A 16-year-old patient with no relevant medical history presented with pain superolateral to the patella after a sports-related injury. Subsequent imaging revealed an anatomic bipartite patella with a disrupted fibrocartilaginous junction. Anatomic bipartite patella are normal variants that typically cause minimal to no pain. Painful variants are most often corrected with surgical excision of the excess bone. Open reduction and internal fixation (ORIF) of the accessory bone to the patella is a rare but proven strategy to reduce pain without excision, especially in patients with tendinous attachment to the accessory bone.

Background: The bipartite patella is a controversial variant, with definitions spanning from normal to stigmata related to patellofemoral dysplasia.
Objective: The purpose of this study is to quantitatively determine if a bipartite patella is in the spectrum of normal versus forme fruste of underlying patellofemoral dysplasia in children using magnetic resonance imaging (MRI) data. A secondary purpose is to assess the MRI findings of the symptomatic bipartite and its implications for patient care.

Introduction: Multipartite patella is an incidental diagnosis, rarely symptomatic, and described scantily in the literature. Symptoms are secondary to direct injury or repetitive micro-trauma, resulting in the separation of fibro-cartilaginous joints across the multiple patellar components. Treatment is usually conservative, and occasionally, in resistant cases, surgery is advised.
