suprapatellar bursa

In a standing posture, the suprapatellar bursa is seemingly redundant.

The largest communicative bursa is the suprapatellar bursa described above.

Fluid from the knee joint also can accumulate in the suprapatellar bursa to form another type of synovial mass.

The suprapatellar bursa is prevented from being pinched during extension by the articularis genus muscle.

The suprapatellar bursa, the largest bursa, extends the joint space anteriorly and proximally.

Retract the patella laterally and flex the knee to gain a good view of the anterior compartment of the joint and the suprapatellar bursa.

Anteriorly, the reflection of the synovial membrane lies on the femur; located at some distance from the cartilage because of the presence of the suprapatellar bursa.

In this position, the A-P diameter of the suprapatellar bursa (anterior and posterior synovial membranes plus effusion) was measured in the longitudinal plane.

Articularis genus pulls the suprapatellar bursa superiorly during extension of the knee, and prevents impingement of the synovial membrane between the patella and the femur.

Anteriorly, the synovial membrane is attached on the margin of the cartilage both on the femur and the tibia, but on the femur, the suprapatellar bursa or recess extends the joint space proximally.
