How To Do Knee Arthrocentesis
Aftercare for Knee Arthrocentesis
Ice, elevation, and oral nonsteroidal anti-inflammatory drugs (NSAIDs) may help relieve pain. With large effusions, apply an elastic bandage after the procedure to help limit swelling and pain. If intra-articular anesthetic has been given, limited joint activity should be prescribed for 4 to 8 hours. Weight-bearing joints, such as the knee or ankle, may be especially prone to injury after anesthetization. If an intra-articular corticosteroid has been given, the joint should be rested for about 24 to 48 hours. If the patient has increased erythema, pain, and/or swelling > 12 hours after the procedure, the joint should be examined for possible infection.
