Miss Tressa Amir is a consultant orthopaedic surgeon with a special interest in shoulder, elbow and upper limb conditions. Her main surgical interests include advances in the arthroscopic (keyhole) treatment for rotator cuff injuries and dislocations of the shoulder as well as joint replacement for shoulder arthritis.

Having qualified from both Cambridge University and Imperial College London, she completed her specialist orthopaedic training on the North-West Thames rotation in London. This gave her the opportunity to work with many world renowned upper limb surgeons. Prior to becoming a consultant, she underwent a one-year advanced UK training fellowship in shoulder, elbow, wrist and hand surgery at the Robert Jones and Agnes Hunt Orthopaedic Hospital in Oswestry.

She is on the GMC specialist register for orthopaedic surgery and is a member of the British Shoulder and Elbow Society (BESS). She is a Consultant Orthopaedic Surgeon at West Hertfordshire Hospitals NHS Trust and the clinical lead for Upper Limb.

Miss Amir was appointed as a Welcome Trust Fellow in 2013 and undertook research on rotator cuff sparing approaches for total shoulder replacement. She was also involved in the development of a new total shoulder replacement with the Biomechanical Engineering Department at Imperial College. Her work has been published and presented internationally.

Miss Amir is involved in the training of higher surgical trainees. She teaches on a number of orthopaedic and trauma courses nationally and is an AO Faculty member. She enjoys teaching and explaining complex principles simply and transfers these skills to help ensure patients have sufficient knowledge and understanding to make informed decisions about their treatment.
