What metals were used in orthopedic implants the 1960s?

Stainless steel was the primary metal used in orthopedic implants during the 1960s. It is a strong and corrosion-resistant metal that was well-suited for use in implants. However, stainless steel can also cause problems with wear and tear, and it can be difficult to machine into complex shapes.

Cobalt-chromium alloys were also used in orthopedic implants during the 1960s. Cobalt-chromium alloys are stronger and more wear-resistant than stainless steel, but they are also more expensive.

Titanium was first used in orthopedic implants in the 1960s, but it was not widely used until the 1970s. Titanium is a strong, lightweight, and corrosion-resistant metal that is ideal for use in implants.
