Biomedical engineers must overcome significant hurdles to create joint replacements that can serve as stand-ins for healthy bone and cartilage. In this podcast, Dr. Sabick outlines how engineers overcome those challenges to make joint replacement an increasingly common and usually successful procedure that improves the quality of life for hundreds of thousands of people every year. She provides a brief overview of the field of biomedical engineering and also details a case study about a patient who needs a hip replacement as an illustration of several key concepts of engineering design.
