“…Green (1975) reported that BP is seen 9 times more in males than females. Other studies showed male/female rate of 2.1 (O'Brien et al, 2011), 3.1 (Kavanagh et al), 3.3 (Ogata, 1994), 3.4 (Oohashi et al) and 4.3 (Weaver, 1977). But these are not the prevalence rates obtained by population scanning, only the ratio of the number of BP cases.…”

KOSE, O.; ERASLAN, A.; ERGUN, A.; EGERCI, O. F. & ERCAN, E. C.Prevalence of bipartite patella in Turkish population; analysis of bilateral knee radiographs in 897 subjects. Int. J. Morphol., 33(3):1108-1113, 2015. SUMMARY:Bipartite patella is a normal anatomic variant of patella. There are various data about the prevalence of bipartite patella in the literature. The aim of this study was to investigate its prevalence, type distribution and sex predilection in Turkish population. Bilateral knee radiographs were retrospectively reviewed of 897 consecutive adult patients. Cases with bipartite patella were categorized according to the Oohashi classification. Medical records were examined in order to differentiate symptomatic and asymptomatic bipartite patellae. We contacted symptomatic patients by telephone to learn continuity of knee pain. We identified 11 cases (7 male, 4 female) of bipartite patella among the 283 male and 614 female patients. No bilateral cases were identified. The prevalence of bipartite patella was 1.22% overall, 2.47% in males, and 0.65% in females. The most common type was superolateral bipartite patella as seen in 9 patients (81.8%). One subject had lateral bipartite and one subject had superolateral tripartite patella. Painful bipartite patella was found in only 2 patients (18%). One of them had continuing symptoms even after 12 months. In conclusion, we found that the prevalence of bipartite patella in Turkish population was approximately 1%. Both inclusion of only adult (skeletally mature) subjects and assessment with bilateral imaging increased the reliability of this value. In accordance with the literature, bipartite patella was found significantly more frequent in males and mostly in superolateral type. More studies are needed in order to obtain the prevalence, type and sex distribution of bipartite patella in different populations.

“…The most commonly encountered patellar variant is the bipartite type and has been reported to be more common in males than females by a ratio of 9:1 [4][5][6][7]. In 1921, Saupe has classified this skeletal variation into three subgroups depending on the location of the fragments.…”

AbstractMusculoskeletal injuries in the non-elite athletes are a clinical entity that is being seen more frequently nowadays. The term “weekend warriors” applies to amateur participants in sports activities and is related to an increasing number of musculoskeletal injuries mainly due to overuse. Concomitant skeletal variations may as well predispose to trauma. We add to the literature two cases of multipartite patella in which locally injected ropivacaine (ropivacaine hydrochloride) and steroid (betamethasone acetate-betamethasone sodium phosphate) relieved the symptoms completely. Here, we describe the clinical, imaging features and the course of treatment.

“…Bourne and Bianco [3] performed a case series of 16 patients (12 males and 4 females), with a mean age of 14.5 (11)(12)(13)(14)(15)(16)(17)(18)(19) years. In their detailed follow-up after 84 (12-156) months, they reported an 'excellent' result in 13 of 16 patients.…”

“…Saupe [23] described the most frequently used classification of bipartite patellae, which is based on the position of the accessory ossification centre. Type 1 (5 %) is characterised by a transverse split and the accessory cen-views can also be helpful [16]. Only 2 % of patients have symptoms [26].…”

“…A bipartite patella therefore results from the failure of the ossification centres to unite, resulting in a fibrocartilaginous union between the bipartite fragment and patella body [4]. The incidence of a bipartite patella is reported as 1 to 2 % in the population [16]. Saupe [23] described the most frequently used classification of bipartite patellae, which is based on the position of the accessory ossification centre.…”

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.
