The operation is usually performed under a general anaesthetic but various anaesthetic techniques are possible. The operation usually takes 45 to 60 minutes.
Impingement is usually treated by an arthroscopy (keyhole surgery). Your surgeon will use instruments to remove any thickened tissue, release any tight tissue and to shave off some bone.
Your surgeon may also be able to repair rotator cuff tears using keyhole surgery. However, they may need to use open surgery. They will use stitches that anchor into the bone.
