“…We found an incidence of unresolved painful bipartite patella of 9.2 per 100,000 recruits. The amount of literature dealing with the existence and surgical excision of bipartite patella in skeletally mature patients is small and consists mainly of case reports [3,11,13]. The principal finding of our study was surgical excision of the accessory patellar fragment resulted in excellent or good functional long-term outcome in all but one patient.…”

“…Postoperative recovery was swift, and no major complications were seen. During the past three decades, surgical excision of painful bipartite patella has been described in some case reports [9,11,23], in limited case series including only a few (five to nine) patients [14,22], and in two studies of comparable size as the current study; one reported favorable outcome for a mixed group of 16 adolescent or adult patients with a followup of 1 year [30], and the other reported complete pain relief for 13 of 16 patients aged approximately 14 years with a 7-year followup [5]. The only previous study focusing solely on adults reported complete pain relief for nine patients, with less than 1-year followup, who underwent excision of a bipartite patella that became painful after injury to the knee [13].…”

Excision of the accessory bipartite fragment is widely used, but its long-term outcome is not known. We evaluated the outcome after surgical excision of a symptomatic accessory bipartite or multipartite patella fragment in young adult men performing their compulsory military service and determined the incidence of painful bipartite patellae in this group of skeletally mature adults. We followed 25 of 32 patients for a minimum of 10 years (mean, 15 years; range, 10-22 years). The incidence of painful, surgically treated bipartite patella was 9.2 per 100,000 recruits. Patients' median age at surgery was 20 years. There were 19 superolateral and six lateral bipartite fragments. Other radiographic findings were rare. At followup, the Kujala score mean was 95 points (range, 75-100 points), and osteoarthrotic changes (Kellgren-Lawrence Grade 1) were seen in two knees. No reoperations related to bipartite patella occurred during the followup. Symptomatic bipartite patella is rare and does not seem primarily associated with anatomic deviations, but when incapacitating pain persists despite nonoperative treatment, surgical excision seems to yield reasonable functional outcome and quick recovery with no apparent adverse sequelae. Our data suggest there is no reason to avoid this technically undemanding procedure for treating persistent symptoms of bipartite patella in young adults.

“…The most frequent is the bipartite patella, but several other bipartite bone and epiphyses are described in the literature such as hamate [4], lunate [1], sesamoid [12], parietal [2], atlas [7], and cuneiform [3]. Frequently, the bipartite bones are asymptomatic, but in some cases, they can cause pain or, more rarely, instability [3,9,13,14,19]. We report what we believe is the first case of a bilateral bipartite ossification center in the proximal tibial epiphysis.…”

“…Numerous cases of bipartite ossific centers have been described including those in the hamate, lunate, sesamoid, parietal, atlas, cuneiform and, most frequently the bipartite patella (0.2% to 6%) [1][2][3][4][5][6][7][8][9][10][12][13][14][15][16][17][18][19][20]. Most bipartite bones represent incidental findings and are asymptomatic, but cases of painful bipartite ossification have been reported [3,9,13,14,19].…”

Bipartite Tibial Epiphysis: Radiologic and Arthroscopic Presentation

We report the case of a bilateral bipartite ossification center of the proximal tibia in a 15-year-old boy with a history of knee injury. The presence of the duplicated ossific centers was an incidental finding on radiography and computed tomography performed after injury. Arthroscopy showed continuous hyaline cartilage between the two ossific centers confirming the diagnosis of a developmental abnormality; however, the articular surface was depressed in the region overlying the smaller ossific center. We presume the presence of an accessory center in the posteromedial aspect of the tibial plate could be a source of instability for the corresponding capsular and meniscal structures. This is, to our knowledge, the first report of tibial bipartite epiphysis.

A bipartite patella in a juvenile from a medieval context

One hundred and thirty six well-preserved medieval skeletons were excavated in advance of re-development in Norwich. The right patella of a 13-15 year old skeleton (SK 65) displays a 'fracture line' running through the supero-lateral pole. This represents the fusion of a secondary ossification centre, a condition known as bipartite patella. It should not be confused with other anatomical variants or with pathological processes.
