Evolution of arthroscopy： from a technique to a subspecialty

The arthroscope was first introduced to orthopaedics as a diagnostic instrument by Tagaki in 1918. A high degree of clinical accuracy, combined with low morbidity, has encouraged the use of arthroscopy to assist in diagnosis, to determine prognosis and often to provide treatment. Arthroscopy has dramatically changed the orthopaedic surgeons＇ approach to the diagnosis and treatment of a variety of joint ailments. Moreover, arthroscopists have specialised in sport medicine and this field was one of the most popular fellowship choices among graduating orthopaedic residents. Arthroscopy has already evolved to an important subspecialty of orthopaedics.
