The knee bursae are the fluid-filled sacs and synovial pockets that surround and sometimes communicate with the knee joint cavity. The bursae are thin-walled, and filled with synovial fluid. They represent the weak point of the joint, but also provide enlargements to the joint space.[1] They can be grouped into either communicating and non-communicating bursae or, after their location – frontal, lateral, or medial.
Knee bursae
Sagittal section of right knee-joint, thus showing only frontal bursae.
X-ray of the knee of a 12-year-old male, with knee effusion extending into the suprapatellar bursa.
In front, there are five bursae:
the suprapatellar bursa or recess between the anterior surface of the lower part of the femur and the deep surface of the quadriceps femoris.[2] It allows for movement of the quadriceps tendon over the distal end of the femur. In about 85% of individuals, this bursa communicates with the knee joint. A distension of this bursa is therefore generally an indication of knee effusion.[3]
the deep infrapatellar bursa between the upper part of the tibia and the patellar ligament.[2] It allows for movement of the patellar ligament over the tibia.[4]
the subcutaneous (or superficial) infrapatellar bursa between the patellar ligament and skin.[2]
the pretibial bursa between the tibial tuberosity and the skin.[2] It allows for movement of the skin over the tibial tuberosity.[4]
