Reducing acute joint swelling: Arthrocentesis (or drainage of joint) may be useful to relieve joint swelling and improve range of motion. Local steroid injections can also reduce fluid accumulation short-term, but do not prevent onset of episodes.
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 .
A Baker's cyst, also known as a popliteal cyst, is a type of fluid collection behind the knee. [4] Often there are no symptoms. [2] If symptoms do occur these may include swelling and pain behind the knee, or knee stiffness. [1] If the cyst breaks open, pain may significantly increase with swelling of the calf. [1]
[5] Diffuse TGCT (D-TGCT) — also called pigmented villonodular synovitis (PVNS)— is a rare tumor that presents as a proliferative, destructive, intra-articular lesion, most commonly in the knee. [3]: 102 [6] Common symptoms of TGCT include swelling, pain, stiffness and reduced mobility in the affected joint or limb. [3]: 102
[1] [6] Diagnosis is generally based on symptom and physical examination. [1] 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]
It generally presents with pain and swelling in the affected bone. [1] Pressure on neighbouring tissues may cause compression effects such as neurological symptoms. [1] The cause is unknown. [1] Diagnosis involves medical imaging. [1] CT scan and X-ray show lytic expansion lesions with clear borders. [1] MRI reveals fluid levels. [1]
When an infection gets into the knee joint, “the knee quickly becomes really swollen, red, and hot,” says Dr. Gladstone. If untreated, infection can affect the whole body, causing fevers and ...
Radiologic images demonstrating degenerative joint damage. Other symptoms that are more typical of psoriatic arthritis than other forms of arthritis include enthesitis (inflammation in the Achilles tendon (at the back of the heel) or the plantar fascia (bottom of the feet)), and dactylitis (sausage-like swelling of the fingers or toes).
