How cold light was introduced to arthroscopy.

Eugen Bircher (1882-1956) the first knee surgeon to use diagnostic arthroscopy.

Eugen Bircher was a strong advocate of diagnostic arthroscopy as shown in several papers on the topic of internal derangements of the knee published between 1921 and 1926. During that time, he performed about 60 endoscopic procedures, which usually preceded a meniscectomy. We believe that this was the first time arthroscopy was used in a large scale for clinical purposes.
