Imagine a doctor doing ordinary activities in his kitchen, stopping to draw some of the everyday objects around him, like an orange and a corkscrew. Then watch him turn those drawings into advanced patents for hip and knee replacements. Dr. Michael Ries holds 45 patents, and many of his ideas came to him in the kitchen. The remarkable efficiency of the human hip and knee are described here through simple illustrations, explaining why hip and knee replacements will never be quite as perfect as the joints we were born with. Health care professionals, patients considering joint replacement, students, and inventors will find The Joint Kitchen informative, entertaining, and thought-provoking. Dr. Ries shows that a state of tranquility allows the creative and problem-solving parts of the brain to connect and form new ideas that can transform and improve lives.
