Bipartite Patella: Symptoms, Causes, and Treatment.
The purposes of this study were to report clinical features of the developmental anomaly of ossification type bipartite or tripartite patella using a large series and to propose a new classification for the developmental anomaly of ossification type bipartite or tripartite patella. The first author prospectively examined 111 patients with symptomatic or asymptomatic bipartite (131 knees) or.
Bipartite patella is a congenital condition (present at birth) that occurs when the patella (kneecap) is made of two bones (instead of a single bone). Normally, the two bones would fuse together as the child grows. But in patella bipartite, they remain as two separate bones. Most of the time, this condition is silent. The.

In a MRI study of 53 patients with bipartite patella, bone marrow edema within the accessory fragment was the sole finding on knee MRI in the majority of the patients. 4 In a histological study the articular cartilage was intact in most of the patients. 12 Most of the cases of painful bipartite patella have been treated using conservative.
PurposeBipartite patella is a known cause of anterior knee pain. Our purpose was to detail the magnetic resonance imaging (MRI) features of bipartite patella in a retrospective cohort of patients imaged at our institution.Materials and methodsMRI exams from 53 patients with findings of bipartite patella were evaluated to assess for the presence of bone marrow edema within the bipartite.
A sunrise view of the patella is obtained with the knee in flexion and the x-ray beam tangential to the patella, throwing the patella into relief by eliminating overlap of the patella with the femur and tibia. This can demonstrate vertical fractures not seen on an AP or lateral view. A bipartite patella is a normal variant that can simulate.
An example of bipartite patella at the superolateral pole; the accessory ossification center at the superolateral pole remains unfused. On an x-ray, you will be able to see that the patella consists of two bones, the smaller part is the unfused segment and it is rounded and usually located laterally—this can be confused with a fracture.
The patella is readily palpable in the supine patient. The main body may be tender to palpation with traumatic contusions or fractures. Occasionally there is a bipartite patella, with a groove between the superolateral portion and the main patellar fragment (Fig. 7-22).This can be a variant of normal. If it is associated with tenderness to palpation, swelling, or crepitus, a patellar fracture.

Bipartite Patella: MR imaging characteristics and frequency I. M. Omar1, M. Schweitzer2 1Radiology, Thomas Jefferson Univerity Hospital, Philadelphia, PA, United States, 2Radiology, New York University Hospital for Joint Diseases, New York, New York, United States Background: Bipartite patella has been described as a developmental variation, usually involving the superolateral aspect of the.
Bipartite patella is usually an asymptomatic, incidental finding. However, in adolescents, it may be a cause of anterior knee pain following trauma or a result of overuse or strenuous sports activity. Most patients improve with nonsurgical treatment. Surgery is considered when nonsurgical treatment fails. Excision of the fragment is the most.

The patella, also known as the kneecap, is a flat, circular-triangular bone which articulates with the femur (thigh bone) and covers and protects the anterior articular surface of the knee joint.The patella is found in many tetrapods, such as mice, cats and birds, but not in whales, or most reptiles.
INTRODUCTION. Bipartite patella is commonly asymptomatic and often an incidental finding on radiological imaging. The patella remains bipartite when secondary ossification centres stop fusing to form a single patella, and may be bilateral in up to 50% of cases (1 Atesok K, Doral MN, Lowe J, Finsterbush A.
