Bipartite Patella Causing Knee Pain in Young Adults: A Report of 5 Cases

Abstract

We report on 5 patients who underwent arthroscopic excision or open reduction and internal fixation for bipartite patella. All patients presented with refractory anterior knee pain. The diagnosis of bipartite patella was made using radiography, and confirmed with magnetic resonance imaging or computed tomographic arthrography. All 5 patients achieved complete resolution of symptoms after surgery, and remained pain-free after a mean follow-up period of 13 months.
