- See: Bipartite Patellae:
- multipartite patella may present diagnostic dilemma in child with anterior knee symptoms;
- these often incidental radiographic findings have been classified into three types:
- type I--at inferior pole (5 % of all lesions)
- type II--at lateral patellar margin (20 %)
- type III--at superolateral pole (75 %)
- exact prevalence of bipartite or multipartite patella is unknown;
- bilaterality is uncommon;
- strong nine-to-one male dominance has been a consistent finding;
- Diff Dx:
- acute fracture
- stress fracture
- dorsal patellar defect;
- exam of symptomatic knee shows slightly enlarged patella w/ tenderness at junction of the main body of patella and the fragment;
- depends on acuity and severity of symptoms;
- w/ acute injry, pain is usually due to separation between fragment and the main body of patella, & knee immobilization for 3 weeks wil suffice;
- in chronic cases, modification of activity over three to four weeks may be all that is required for resolution;
- if symptoms persist, entire fragment, through region where fragment meets the body of the patella, may be excised to eliminate the
