Joint aspiration (arthrocentesis) is a procedure where fluid is drained from a joint with a needle and syringe for laboratory analysis. This may help determine the causes of joint swelling or arthritis.
Rheumatoid arthritis is an autoimmune disease that causes chronic inflammation of the joints, the tissue around the joints, as well as other organs in the body. Because it can affect multiple other organs of the body, rheumatoid arthritis is referred to as a systemic illness and is sometimes called rheumatoid disease.
Gout is a condition that results from crystals of uric acid depositing in tissues of the body. Gout is a condition that can lead to abnormally elevated levels of uric acid in the
blood, recurring attacks of joint inflammation (arthritis), deposits of
hard lumps of uric acid in and around the joints, and decreased kidney
function and kidney stones.
The knee joint is composed of three compartments and ligaments which stabilize the joint. Causes of knee pain may include injury, degeneration, infrequently infection and rarely bone tumors. Although routine x-rays do not revel meniscus tears, they can be used to exclude other problems of the bones and tissues. The knee joint is the most commonly involved joint in rheumatic disease, as well as immune diseases that affect various tissues of the body.
Lyme disease is a bacterial illness, which is spread by ticks when they bite the skin. Initially the disease affects the skin causing a reddish rash associated with flu-like symptoms. It takes weeks to months after the initial redness of the skin for its effects to spread throughout the body. Lyme disease can be treated with antibiotics. Lyme disease can be prevented by using tick avoidance techniques.
Arthritis is inflammation of one or more joints. When joints are inflamed they can develop stiffness, warmth, swelling, redness and pain. There are over 100 types of
arthritis including osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, lupus, gout,
and pseudogout.
Chronic pain is pain (an unpleasant sense of discomfort) that persists or progresses over a long period of time. In contrast to acute pain that arises suddenly in response to a specific injury and is usually treatable, chronic pain persists over time and is often resistant to medical treatments.
Brucellosis is an infectious disease caused by the Brucella bacteria. Symptoms and signs include sweating, fever, fatigue, dizziness, headache, cough, chest, joint, and abdominal pain, and enlarged liver and/or spleen. Brucellosis is treated with antibiotics.
Plant thorn synovitis (plant thorn arthritis) is joint inflammation caused by a thorn puncturing the joint and leaving residual plant matter in the joint. Symptoms and signs include swelling, reddish discoloration, loss of range of motion, pain, tenderness, and stiffness. Treatment involves a surgical procedure called a synovectomy with joint lavage to remove the affected joint lining tissue and thorn fragments.
Hydroxyapatite crystal disease is the inflammation caused by hydroxyapatite crystals. These tiny crystals of hydroxyapatite deposit by mistake in or around joints and may cause inflammation of the joints and nearby tissues such as the tendons and ligaments (particularly causing rotator cuff problems in the shoulder). Treatment options include rest, cold application, medications to reduce inflammation, and cortisone-related medication injections.
