If you have had two or three hydrodilatations and your shoulder is still very stiff, then it is an option to consider shoulder arthroscopy. Shoulder arthroscopy is key hole surgery on the shoulder – it allows for a full assessment of the shoulder, followed up by removal of all scar tissue in the shoulder joint. Following the release, the shoulder is gently manipulated under anaesthetic to regain full movement.
Any surgical or invasive procedure carries risks. Before proceeding, you should seek a second opinion from an appropriately qualified health practitioner.
