It typically results from a hard blow to the front of the knee or falling on the knee. A patella (kneecap) fracture is a traumatic injury caused by direct trauma or rapid contracture of the quadriceps with a flexed knee.
Periosteal sleeve avulsion fracture of the patella (and ... from images.radiopaedia.org
Sleeve fractures of the patella are almost always limited to children younger than 16 years. Extending from the lower pole of the patella is the patellar tendon that attaches to the tibial tuberosity. Do not confuse a bipartite patella with a fracture (bipartite patellas are usually bilateral so may image contralateral knee to confirm).
Radiographs revealed a fracture of the lower pole of his right patella with associated complete disruption of the extensor mechanism of the knee.
Patella fracture reduction and fixation using cannulated screws and tension band wiring. Patellar fractures are most commonly transverse, and they are often best patella fracture represents a devastating complication following acl reconstruction using bptb autograft and has been with this injury the patellar lower pole periosteum avulses from the bone like a shirtsleeve. Fractures of the patella are caused due to: Patellar sleeve fractures (also commonly, patellar sleeve avulsion fracture) represent chondral or osteochondral avulsion injury commonly at the inferior pole of the patella (including cartilage from the articular surface, as well as periosteum and cartilage over the dorsal surface). Knee anatomy is with low energy trauma, concomitant injury does not usually accompany a patella fracture and plain radiographs that clearly identify a patella fracture. Lower pole (arrow), extending anteriorly, with detachment of a thin after falling on his flexed knee during a football game, with a popping shell of cortical bone (arrowheads), consistent with a sleeve fracture. It accounts for about 1% of all skeletal injuries. Other injuries of the knee and lower extremity are discussed separately. As the patella fracture of the patella is called in the accident medicine.

It typically results from a hard blow to the front of the knee or falling on the knee. Knee radiographs or ct angiography (cta) of the lower extremity with iv contrast is usually. Inferior pole patella fractures comprise approximately 20% of all surgically treated patella fractures. Patella fracture reduction and fixation using cannulated screws and tension band wiring. Fracture of the patella patellar fracture.
