My teenager daughter has been diagnosed with a vacuum phenomenon in her knee please can you tell me the best way to treat this as she is in quite a bit of discomfort (she is a ballet dancer) but because there is no large swelling our doctor has not referred us for any further treatment but did not give us any guidance on what to do
Hello. Thank you for writing us here. Well vacuum phenomenon is just pressure change in the capsule of joint. You can get a small puncture done at knee joint to relieve the pain. Best regards Chat Doctor.
