Hydrarthrosis (/ˌhaɪdrɑːrˈθroʊsɪs/) is a medical term that refers to the accumulation of fluid in a joint cavity. The spelling of this complex word can be broken down into its phonetic components. The prefix "hydr-" means water, followed by the combining form "-arthr-" meaning joint, and the suffix "-osis" indicating a condition. The IPA transcription of each phoneme helps to elucidate the spelling and pronunciation of this technical term. Diagnosing hydrarthrosis involves imaging techniques such as X-rays, MRI, and ultrasound to determine the extent of fluid build-up in the affected joint.
Hydrarthrosis is a medical term used to describe a condition characterized by the accumulation of excessive synovial fluid within a joint, causing swelling, pain, and limited range of motion. The term is derived from the Greek words "hydra" meaning water and "arthron" meaning joint.
Hydrarthrosis commonly affects weight-bearing joints such as the knees, ankles, and hips. It is often associated with underlying joint disorders like osteoarthritis, rheumatoid arthritis, gout, or joint injury. In these conditions, inflammation in the joint lining, known as the synovium, triggers the excessive production of synovial fluid, which is normally responsible for lubricating and nourishing the joint.
The accumulation of synovial fluid in hydrarthrosis leads to joint swelling, which can cause pain, stiffness, and a feeling of pressure within the affected joint. Movements and weight-bearing activities may become challenging, affecting mobility and quality of life.
The diagnosis of hydrarthrosis is typically made through physical examination, medical history, and imaging tests such as X-rays or MRI scans to evaluate the joint and the amount of fluid present. Treatment options for hydrarthrosis may include conservative measures such as rest, ice, compression, and elevation (RICE), non-steroidal anti-inflammatory drugs (NSAIDs) to reduce swelling and pain, and intra-articular injections of corticosteroids or hyaluronic acid. In some cases, surgical interventions like arthrocentesis (joint aspiration) may be required to remove excess synovial fluid, alleviate symptoms, and identify the underlying cause of the condition.
In summary, hydrarthrosis is a condition characterized by excessive accumulation of synovial fluid within a joint, leading to joint swelling, pain, and limited

The word "hydrarthrosis" is derived from two Greek roots: "hydro" meaning "water" and "arthro" meaning "joint".
- The Greek word "hydro" (ὕδωρ) comes from the Indo-European root "wed-", which means "water" and has given rise to words like "hydrology", "hydrate", and "hydrogen".
- The Greek word "arthro" (ἄρθρον) means "joint" and is related to the Sanskrit word "jānāti", which means "to know" or "to perceive".
When combined, "hydro" and "arthro" form the word "hydrarthrosis", which refers to the abnormal accumulation of fluid within a joint, often caused by inflammation.
