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. It is basically a disease of children and adolescence. [6]
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 .
Intermittent hydrarthrosis (IH), also known as periodic synoviosis, periodic benign synovitis, or periodic hydrarthritis, is a chronic condition of unknown cause characterized by recurring, temporary episodes of fluid accumulation in the knee.
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 .
Medical algorithms based on best practice can assist everyone involved in delivery of standardized treatment via a wide range of clinical care providers. Many are presented as protocols and it is a key task in training to ensure people step outside the protocol when necessary.
The tests also include MRI, ultrasound and X-ray test, which give better information about the joint inflammation. [7] Although MRI is superior method for this assessment, the US using the HEAD-US method performed by paediatric radiologists is a reliable tool for detection and quantification of haemophilic arthropathy in children in comparison ...
The patellar tap is a technique used in an examination of the knee to test for knee effusion or "water-on-the-knee". [1] With the examinee lying on their back, the examiner extends the knee and presses the area above the kneecap with the palm of one hand. This pushes fluid under the kneecap and lifts it.
Chest X-ray and chest CT may show pleural effusion, nodules, infiltrates, abscesses and cavitations. [citation needed] Bacterial cultures taken from the blood, joint aspirates or other sites can identify the causative agent of the disease. [citation needed] Other illnesses that can be included in the differential diagnosis are: [citation needed ...
