Fine Needle Aspiration
Fine Needle Aspiration (FNA) is a minimally invasive procedure used to remove fluid from a joint or cyst for diagnostic or therapeutic purposes. At RAD Clinics, we offer this advanced treatment using the latest ultrasound-guided techniques to ensure precision and comfort. FNA is an effective method to help reduce swelling, relieve discomfort, and gather samples for further analysis when necessary.

Mode of Action of Fine Needle Aspiration
The purpose of fine needle aspiration is to withdraw fluid from a joint or cyst using a thin, hollow needle. By extracting excess fluid, FNA helps relieve pressure, reduce swelling, and in some cases, prevent further complications. It is also a useful diagnostic tool, as the fluid collected can be analysed to determine the presence of infection, inflammation, or other underlying conditions.

Procedure of Fine Needle Aspiration for Joint or Cyst
The FNA procedure at RAD Clinics is performed under sterile conditions and typically involves the following steps:
- Preparation: The area around the joint or cyst is cleaned, and local anaesthetic may be used to minimise discomfort.
- Needle Insertion: A fine, hollow needle is inserted into the joint or cyst under ultrasound guidance to ensure precise placement.
- Fluid Aspiration: Fluid is gently withdrawn through the needle into a syringe.
- Post-Procedure: A dressing is applied to the area, and the patient is usually able to return to normal activities shortly after the procedure.
Procedure of Fine Needle Aspiration for Joint or Cyst
At RAD Clinics, we use real-time ultrasound guidance to ensure accuracy and safety during the FNA procedure. Ultrasound imaging allows the practitioner to visualise the joint or cyst, ensuring that the needle is positioned correctly. This increases the precision of the aspiration, reduces discomfort, and minimises the risk of complications.
Conditions Treated with Fine Needle Aspiration
Joint Effusion
Excess fluid build-up in the joint, often due to inflammation or injury.
Cysts
Such as ganglion cysts or Baker’s cysts, which can cause discomfort and swelling.
Benefits of Fine Needle Aspiration for Joint or Cyst
- Minimally Invasive: FNA is a quick, non-surgical procedure that avoids the need for more invasive treatments.
- Relief from Discomfort: By removing excess fluid, the procedure can alleviate pressure and reduce pain.
- Accurate Diagnosis: Fluid aspirated during the procedure can be sent for analysis to identify potential causes of joint swelling or cyst formation.
- Quick Recovery: Patients typically experience minimal downtime and can return to normal activities shortly after the procedure.
- Precision: Ultrasound guidance ensures accurate needle placement and a more comfortable experience for the patient.

What size needle is used to drain a cyst?
The needle size used for cyst drainage depends on the cyst's location, size, contents and the procedure required. RAD Clinics uses a fine, hollow needle under ultrasound guidance to position the needle accurately and withdraw fluid safely.
Is fine needle aspiration performed under ultrasound?
Yes, fine needle aspiration at RAD Clinics is performed under real-time ultrasound guidance. Ultrasound allows the clinician to visualise the cyst or joint and position the needle accurately during aspiration.
Where can I get a fine needle aspiration done?
