Manipulation Under Anaesthesia, commonly known as MUA, is often the first intervention recommended to patients with a stiff knee after surgery. But what does this procedure actually involve, and what are the risks? In our latest interview, IAA founder Kayley Usher sits down with Dr. Ralph Rosenberger, an orthopaedic surgeon in Austria who specialises in arthrofibrosis and revision knee surgery, to discuss why patients should think carefully before agreeing to a manipulation.

In Part 1 of this series, we explored how Dr. Marco Valoroso approaches the diagnosis of knee arthrofibrosis after total knee replacement (TKR), as well as the imaging tools and clinical reasoning that guide his evaluations. In this second half of our conversation, we turn to the surgical aspects of treatment — from manipulation under anesthesia to surgical strategies, revision decisions, and best practices to prevent recurrence.

Welcome to the inaugural international panel discussion on the surgical treatment of arthrofibrosis.
