Ian Scott Smillie (15 April 1907 – 18 March 1992) was a British professor of orthopaedic surgery who became an international authority on conditions of the knee.

After junior hospital posts in Chester and Grimsby, he became, in 1936, clinical assistant to Mr (later Sir) Walter Mercer who later became the first Professor of Orthopaedic Surgery in Edinburgh.

[1][2] At the start of World War II Smillie was appointed surgeon in charge of the Emergency Medical Service Hospital at Larbert, Stirlingshire.

In both centres he continued to promote and develop the concept of team care in orthopaedics and emphasised the importance of rehabilitation.

[7] Smillie was an enthusiastic advocate of removal of the injured meniscus and developed instruments and techniques to facilitate this procedure.

From the 1980s advances in technology and understanding of the adverse consequences of meniscectomy led to a more conservative approach being adopted.

[5][11] The Ian Smillie award is presented each year by the University of Dundee to the most distinguished student on the Master of Orthopaedic and Trauma Surgery (ChM Orth) course.
