In the case of osteoarthritis, fluid within the joint can be drained to relieve pain and an anaesthetic and steroid injection put into the joint cavity to reduce pain and stiffness.
The most comfortable approach to use is a posterior one.
Joint aspirate can be taken away and local anaesthetic and hydorcortizone put into the joint to relieve pain.
This is used to reduce symptoms of impingement especially when the bursa is inflamed.
Hydrocortizone is injected to reduce symptoms of tendonitis or partial tear.
It is advisable to avoid vigorous activity for one week after the injection.
