About ISTA

Following a series of international symposia focused on the development of custom prostheses for arthroplasty, the International Society for the Study of Custom Prostheses (ISSCP) was formally established in 1990. In 1994, as the Society expanded its scope to encompass a broader range of interests, its name was changed to the International Society for Technology in Arthroplasty (ISTA).

Mission Statement

The corporation is a nonprofit public benefit corporation and is not organized for the private gain of any person. It is for public and charitable purposes.
