There are over one million joint replacement surgeries each year in the United States alone! Most of these are knee replacements followed by hip replacements, and all of them are gross sounding.

The technology used for joint replacement has improved over the years, allowing your fake knees and hips to last longer and work better than in the past. We researched what goes into joint replacement surgery (it sounds just the worst), what materials are used to help you get the best results, and previewed new technology that is being worked on to make this process even better in the future.
