Bipartite patella is recognized as a developmental anomaly of ossification. Most of them are asymptomatic and are discovered incidentally. Bipartite patella is sometimes misdiagnosed as a patella fracture, because the x-ray images of both these conditions may appear very similar. In this case, the patient complained of left knee pain after x-ray films revealed a fracture-like line in the left patella. The patient was then diagnosed as having a patella fracture. In China, the injury degree is categorized as serious injury, minor injury, and trivial injury. As the injury degree of patellar fracture is identified as minor injury, the defendant who injured the patient will be sentenced to prison for ≤3 years. However, the defendant objected to this judgment and applied for the second evaluation of injury degree. On the basis of the site of injury, clinical manifestations, and imaging findings, we diagnosed the patient with bipartite patella which belongs to normal anatomic variant. Therefore, the injury degree of the patient was not minor injury.

“…‘Bipartite’ or ‘tripartite’ patellae are also described in cats, and some authors have hypothesised that a developmental anomaly occurs during patellar ossification resulting in patellar non-union in this species (Langley-Hobbs and others 2008, Langley-Hobbs 2009, Hermer and others 2012). It is likely that such a non-union is a consequence of several centres of ossification within the patella in cats as well as in human beings or dogs (Langley-Hobbs 2009, Oohashi 2015). …”

A 15-month-old female Belgian Malinois presented with an inability to ambulate on its pelvic limbs after running away. Orthopaedic examination revealed painful stifles, crepitus and a bilateral lack of patellar continuity. Radiographs confirmed bilateral patellar fractures showing a similar fracture pattern on both sides, with three parts divided in the shape of a ‘Y’. Surgical treatment consisted of fracture stabilisation using pins and wires protected by a tibio-patellar prosthesis and type Ia external fixator. Bone healing occurred and a satisfactory level of function was observed at long-term follow-up. This report describes the original presentation of bilateral patellar fractures in a dog. The bilateral presentation and similar fracture pattern on both sides potentially support the notion that failure of the patellar secondary ossification centres to unite caused fragility of both patellae.

“…Sometimes it develops from 2 (bipartite) or more (multipartite) ossification centers and the segments are united by fibrous union (25,26). Acute or chronic repetitive trauma to the patella can result in painful bipartite or multipartite patella.…”

Recurrent or chronic activity related knee pain is common in young athletes. Numerous intrinsic conditions affecting the knee can cause such pain. In addition, knee pain can be referred pain from low back, hip or pelvic pathology. The most common cause of knee pain in young athletes is patellofemoral pain syndrome, or more appropriately termed idiopathic anterior knee pain. Although, numerous anatomical and biomechanical factors have been postulated to contribute the knee pain in young athletes, the most common underlying reason is overuse injury. In this paper, we have reviewed selected conditions that case knee pain in athletes, including anterior knee pain syndrome, Osgood-Schlatter disease, Sinding-Larsen-Johanssen syndrome, juvenile osteochondritis dissecans (JOCD), bipartite patella, plica syndrome, and tendonitis around the knee.
