DESIGNING SHAPE & STRUCTURE
|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.
