Prepatellar Bursa

Fig. 3.37a,b. Complete tendon tear, a Long-axis 12-5 MHz US image over the quadriceps tendon with b fat-suppressed T2-weight-ed MR imaging correlation shows a transverse hypoechoic gap in the tendon substance fiUed with fluid (asterisks) between the proximal and distal ends (arrows), consistent with a complete rupture. Note that the tendon tear forms a communication between the joint and the prepatellar bursa. P, patella... 

There are several bursae around the knee. These may be either subcutaneous in location (such as the prepatellar bursa and the superficial infrapatellar bursa), between tendons and bone (such as the deep infrapatellar bursa) or between tendons and ligaments (such as the anserine bursa, the semi-membranosus-medial collateral ligament bursa and... 

From the anatomic point of view, the subcutaneous prepatellar bursa is located anterior to the lower half of the patella and the proximal patellar tendon, just deep to the skin. More caudally, the superficial infrapatellar bursa is located between the tibial tuberosity and the skin. The deep infrapatellar bursa lies between the deep boundary of the distal patellar tendon and the anterior aspect of the tibia. The anserine bursa intervenes between the superficial... 

The prepatellar bursa is a synovium-lined structure located in the subcutaneous tissue over the lower half of the patella and the upper third of the patel-... 

The infrapatellar area includes the patellar tendon, the prepatellar and infrapatellar bursae and the Hoffa fat pad. Both longitudinal and trans-... 

US findings of acute prepatellar bursitis reflect the underlying pathology. In an acute gout attack, US detects an anechoic intrabursal effusion, whereas in post-traumatic bursitis the blood filling the bursa...
