Pes anserine bursitis is an inflammatory condition of the medial (inner) knee at the anserine bursa, a sub muscular bursa, just below the pes anserinus. Pathology [ edit ]
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 ]
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 anserinus tendinitis/bursitis syndrome, or pes anserine bursitis, is a cause of chronic knee pain and weakness. [3] [4] It occurs when the medial portion of the knee is inflamed. If the bursa underlying the tendons of the sartorius, gracilis, and semitendinosus gets irritated from overuse or injury, a person can develop this ailment. This ...
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.
Knee effusion, informally known as water on the knee, occurs when excess synovial fluid accumulates in or around the knee joint. It has many common causes, including arthritis , injury to the ligaments or meniscus , or fluid collecting in the bursa , a condition known as prepatellar bursitis .
The numerous bursae surrounding the knee joint can be divided into the communicating and the non-communicating bursae: [2] Communicating bursae: 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
When the deep bursa is involved, bending the knee generally increases the pain. [2] Other conditions that may appear similar include patellar tendonitis and prepatellar bursitis. [5] Treatment is generally by rest, alternating between ice and heat, and NSAIDs. [1] Infrapatellar bursitis is relatively rare. [4]
