Joint Puncture – Arthrocentesis – For Joint Diagnosis and Treatment
Joint puncture, also known as arthrocentesis, is a medical procedure that involves inserting a needle into a joint for diagnostic or therapeutic purposes. This procedure may be performed by an orthopedist, rheumatologist, or other joint specialist.
Why is a joint puncture performed?
A joint puncture may be performed for several reasons:
- Diagnostic reasons:
- Synovial fluid analysis: Taking a sample of fluid from a joint for analysis can help diagnose conditions such as infection, inflammation, gout, or bleeding in the joint.
- Diagnosis of arthritis: Identifying the type of arthritis, whether it is rheumatoid, osteoarthritis, gouty arthritis, or another form.
- Therapeutic reasons:
- Removal of excess fluid: Reducing swelling and pain by removing excess fluid from the joint.
- Administration of medications: Injecting medications such as corticosteroids or hyaluronic acid directly into the joint to reduce inflammation and pain.
How is a joint puncture performed?
The doctor will examine the patient and take a medical history, including questions about current symptoms, medications, and allergies. The area around the joint will be cleaned with an antiseptic to reduce the risk of infection. Local anesthesia may be used to reduce pain during the procedure.
Joint Puncture Procedure
The doctor will insert a sterile needle into the joint cavity. Fluid will be aspirated (withdrawn) from the joint using a syringe. If necessary, medications will be injected into the joint through the same needle.
After the Joint Puncture Procedure
Pressure and a bandage will be applied to the puncture site to reduce bleeding and swelling. The orthopedist will advise you to rest the joint and avoid strenuous activity for several days.
Possible complications after joint puncture
Although a joint puncture is generally a safe procedure, some complications can occur, including:
- Infection
Risk of infection at the puncture site.
- Bleeding
Minor bleeding or hematoma formation at the injection site.
- Pain
Pain or discomfort during or after the procedure.
- Damage to structures
Damage to joint structures, although this is rare.
When is joint puncture recommended?
Joint swelling of unknown cause. Suspected joint infection. Joint pain that does not respond to usual treatments. The need for diagnosis of a specific type of arthritis. The need to inject medication directly into the joint.
