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 .
Repeated, periodic joint effusions of the knee. Usually one knee is affected but sometimes both knees. Other joints may also be involved along with the knee. Effusions are large, restricting range of motion but significant pain is not a feature. There is usually stiffness. Tenderness of the joint may or may not be present. [1]
Septic arthritis is the purulent invasion of a joint by an infectious agent [5] [6] with a resultant large effusion due to inflammation. [7] Septic arthritis is a serious condition. It can lead to irreversible joint damage in the event of delayed diagnosis or mismanagement.
Osteoarthritis is the most common cause of a joint effusion of the knee. [ 15 ] In smaller joints, such as at the fingers, hard bony enlargements, called Heberden's nodes (on the distal interphalangeal joints ) or Bouchard's nodes (on the proximal interphalangeal joints), may form, and though they are not necessarily painful, they do limit the ...
A tibial plateau fracture is a break of the upper part of the tibia (shinbone) that involves the knee joint. [1] This could involve the medial, lateral, central, or bicondylar (medial and lateral). [3] Symptoms include pain, swelling, and a decreased ability to move the knee. [1] People are generally unable to walk. [2]
Joint effusion and limited range of motion are common associated features. It affects primarily large joints, including knee (>50% of cases), elbow, hip, and shoulder. SOC is twice as common in men as women. Some patients have intra-articular bodies resting in stable positions within joint recesses or bursae.
General symptoms are stiffness, swelling, synovial effusion, pain, redness, tenderness, grinding, instability and intra-articular bleeding of the injured joint. [1] [11] As a result of these symptoms, post-traumatic arthritis often comes along with the loss of ability.
Arthrocentesis, or joint aspiration, is the clinical procedure performed to diagnose and, in some cases, treat musculoskeletal conditions. The procedure entails using a syringe to collect synovial fluid from or inject medication into the joint capsule .
