Clinical features include pain, swelling, tenderness, and bursitis (especially suprapatellar
The probe was placed in the axial plane in the suprapatellar
Significant improvement in VAS, SF-36, WOMAC score, hyperemia, and thickness of suprapatellar
recess synovium from baseline was seen up to 6 months after intra-articular HA injection.
It can be seen in the overall joint, particularly in the suprapatellar
pouch, presenting as hyperintense in T1 and intermediate to hyperintense in T2 sequence (Figure 2a, b).
Slightly larger pea-sized loose bodies were noted, mainly in the suprapatellar
It originates from the anterior surface of the distal aspect of the femur and inserts into the proximal and posterior aspects of the suprapatellar
A bursa around the knee was classified as present when there was more than 5 mm of synovial liquid in the suprapatellar
bursa and as absent when there was less than 5 mm. Other fluid-filled bursae were considered present or absent and described based on their locations.

effusion by ultrasonography and its association with symptoms of radiographic knee osteoarthritis: a cross-sectional observational study," Arthritis Research & Therapy, vol.
Synovial biopsies obtained during debridement from the suprapatellar
pouch were sent for both microbiology and pathology.
Physical examination revealed tenderness and a gap in both suprapatellar
regions, no active motion in the extensor mechanism, and palpable defects in the quadriceps tendons with respect to attachment to the patella.
There was an associated suprapatellar
effusion without evidence of infiltration through the physis.
Popliteal fat was totally absent, but infrapatellar fat was very well preserved, and some adipose tissue was also evident in suprapatellar
