“…6 In traumatic fractures, the margins of the fracture fragments are more ragged, whereas in non-traumatic fractures, the accessory fragments tend to have sclerotic, smooth margins. Magnetic resonance imaging is the diagnostic tool of choice.…”

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 followup period of 13 months.

“…We define conservative treatment as anything that does not require surgery. Both Okuno et al [19] and Stocker and Laer [24] assessed the effectiveness of immobilisation. In both studies, teenage patients suffered indirect patella trauma, with fracture across the bipartite synchondrosis.…”

“…This was diagnosed by clinical findings and plain radiographs. Okuna et al [19] immobilised two patients for 3 weeks followed by gradual resumption of sport. Both patients returned to full sporting activity within 3 months, and radiographic union of the bipartite fragment had occurred by 4 months follow-up.…”

Purpose This study aimed to identify the most effective method for the treatment of the symptomatic bipartite patella. Methods A systematic review of the literature was completed, and all studies assessing the management of a bipartite patella were included. Owing to the paucity of randomised controlled trials, a narrative review of 22 studies was completed. A range of treatments were assessed: conservative measures, open and arthroscopic fixation or excision and soft tissue release and excision. Results All of the methods provided results ranging from good to excellent, with acceptable complication rates. Conclusions This is a poorly answered treatment question. No firm guidance can be given as to the most appropriate method of treating the symptomatic bipartite patella. This study suggests that there are a number of effective treatments with acceptable complication rates and it may be that treatments that conserve the patella are more appropriate for larger fragments. Level of evidence IV.

“…Therefore, I suppose that in the case of the developmental anomaly of ossiWcation type bipartite patella, consolidation may not take place and when consolidation is shown, it is probably fracture or stress fracture of the patella or accessory ossiWcation centers of the patella [3]. Okuno et al [4] also described traumatic separation of a type I bipartite patella and bone union was obtained in their conservatively treated cases. However, these cases may also represent a transverse fracture or transverse stress fracture of the distal part of the patella.…”
