Abstract
Autor introduces an overview of current treatment options for symptomatic bipartite patella treated both conservatively and by surgery. Bipartite patella or congenital fragmentation of the patella is a rare condition involving 2-6% of population.
In most cases, bipartite patella appears to be asymptomatic. In the case of an extensive overload or after a trauma, pre-existing bipartite patella can become symptomatic and painful.
In addition to medical history and proper clinical examination, the most important in the diagnosis of bipartite patella are skyline views for patella or MRI imaging. Most of the painful bipartite patellae respond well to conservative treatment.
Where symptoms persevere despite the conservative treatment measures, surgery may be indicated. The surgery includes surgical excision of the accessory fragment, lateral retinacular release or lateral vastus desinsertion from the accessory fragment.
All the options have been reported with good long-term outcomes. Open osteosynthesis is indicated rarely and for specific indications only.
