The Hospital for Special Surgery moves to its East River site between 70th and 71st Streets
The Hospital for Special Surgery relocates in 1955 to its present campus beside the East River, running from East 70th to East 71st Street, after occupying a building at 42nd Street and Second Avenue since 1912. By then it had carried its current name for fifteen years, and one of the country's earliest bone banks had been set up at the hospital in 1948.

John Insall completes the first total condylar knee implant
In February 1974 the orthopedic surgeon John Insall, who had joined the hospital in 1961, completes the first implant of the Total Condylar Prosthesis. The design grew out of his work with Peter Walker on the Duocondylar prosthesis in 1970. Insall later refined it as the Total Condylar Prosthesis II in 1976 and 1977 and went on to serve as president of the Knee Society in 1987.
