Wrecked Knees? Nose Cartilage Can Fix Them, University of Basel Study

IF YOU need a new knee, look no further than the end of your nose. It turns out that nasal cartilage is a good substitute for the knee's natural shock-absorbing tissue – so much so that nine people have undergone the first nose-to-knee cartilage transplant. Unlike many tissues in the body, cartilage, which covers and cushions the surface of joints, has little capacity to regenerate once damaged. Sports injuries or falls can lead to loss of cartilage, but it also degenerates in diseases like osteoarthritis. Treatment options are limited and people often need to have the entire joint replaced with an artificial one.
