for strength and the plastic coating that is done on it acts as an artificial cartilage. The biodegradable metals in this category are magnesium-based and iron-based alloys, though recently zinc has also been investigated. Currently, the uses of bioresorbable metals are as fracture fixation implants

The discipline of orthopedic implants is constantly evolving as new biomaterials become available. An important consideration in this respect is that the health status of the patient influences the optimal choice of the material to be implanted. For instance it was shown that patients with steatotic liver disease benefit from nanohydroxyapatite-coated (nHA) titanium surfaces, whereas this is not necessary for patients without fatty liver disease. A
