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 ]
These include the subacromial, prepatellar, retrocalcaneal, and pes anserinus bursae of the shoulder, knee, heel and shin, etc. (see below [broken anchor]). [1] Symptoms vary from localized warmth and erythema (redness) [ 1 ] to joint pain and stiffness, to stinging pain that surrounds the joint around the inflamed bursa.
Examples include the subacromial bursa that protects the tendon of shoulder muscle as it passes under the acromion of the scapula, and the suprapatellar bursa that separates the tendon of the large anterior thigh muscle from the distal femur just above the knee. [1] An adventitious bursa is a non-native bursa.
The suprapatellar bursa, the largest bursa, extends the joint space anteriorly and proximally. The subpopliteal recess and semimembranosus bursa are located posteriorly and are much smaller; The lateral and medial subtendinous bursae of gastrocnemius are located at the origin of the two heads of the gastrocnemius muscle. Non-communicating bursae:
Knee pain affects about 15 to 33 percent of cyclists, according to a 2018 systematic review published in Open Access Journal of Sports Medicine. ... you may have a type of bursitis.
Prepatellar bursitis is an inflammation of the prepatellar bursa at the front of the knee. It is marked by swelling at the knee, which can be tender to the touch and which generally does not restrict the knee's range of motion. It can be extremely painful and disabling as long as the underlying condition persists.
Risk factors include other knee problems such as osteoarthritis, meniscal tears, or rheumatoid arthritis. [1] [3] [4] The underlying mechanism involves the flow of synovial fluid from the knee joint to the gastrocnemio-semimembranosus bursa, resulting in its expansion. [1] The diagnosis may be confirmed with ultrasound or magnetic resonance ...
Pes anserine bursitis may result from stress, overuse, obesity and trauma to this area. An occurrence of pes anserine bursitis commonly is characterized by pain at the medial knee and upper tibial region, especially when climbing stairs, tenderness, and local swelling. [2]
