Challenges to Creating Replacements That Work>>
  A successful replacement joint has to be designed to:  
  • Be easy for the surgeon to put in without damaging surrounding tendons and ligaments.
  • Work for people of different sizes and shapes.
  • Replicate the motion of the original joint as closely as possible.
  • Produce minimal friction and wear when it moves, so that it lasts a long time.
  • Be able to be attached to the surrounding bone without damaging or weakening it too much.

In the 1930s and 40s, a few pioneering surgeons began to experiment with hip replacements.
