First joint to be built artificially?

The first joint to be built artificially was the artificial hip joint, developed in the 1960s by Sir John Charnley. His pioneering work in hip replacement surgery revolutionized orthopedic medicine by providing a solution for patients suffering from severe Arthritis and joint degeneration. The synthetic joint allowed for improved mobility and pain relief, setting the stage for advancements in joint replacement technology. This innovation has led to the development of various artificial joints used in knees, shoulders, and other joints today.
