( Joint Aspiration)

 

What to Expect

Anesthesia

Your doctor may give you local anesthesia. This numbs the area where the needle will enter the joint.

Description of the Procedure

Your doctor will clean the area where the needle will be inserted. Next, a needle attached to a syringe will be inserted into the fluid-filled joint cavity. Your doctor will draw the fluid into the syringe. After this, the doctor may take the syringe off and inject some medicine into the joint through the needle. After the needle is removed, the doctor will put pressure on the spot over the joint. A bandage will be placed over the area.

How Long Will It Take?

About 5-10 minutes

How Much Will It Hurt?

You may feel stinging or burning if local anesthesia is injected into the area.

Post-procedure Care

When you return home after the procedure, do the following to help ensure a smooth recovery:
  • For the first 24 hours, use an ice pack for 15-20 minutes at a time every 3-4 hours. Place a towel between your skin and the ice pack.
  • To reduce discomfort, take a pain reliever.
  • Ask your doctor when you can resume normal activities.
  • Be sure to follow your doctor's instructions.
