An orthopedic implant is a medical device manufactured to replace a missing joint or bone, or to support a damaged bone.[1] The medical implant is mainly fabricated using stainless steel and titanium alloys for strength and the plastic coating that is done on it acts as an artificial cartilage.[2] The biodegradable metals in this category are magnesium-based [3] and iron-based alloys, though recently zinc has also been investigated.[4] Currently, the uses of bioresorbable metals are as fracture fixation implants[5][6][7][8] Internal fixation is an operation in orthopedics that involves the surgical implementation of implants to repair a bone.[9][10] During the surgery of broken bones through internal fixation the bone fragments are first reduced into their normal alignment then they are held together with the help of internal fixators such as plates, screws, nails, pins, and wires.[11][12]

Research progress
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.[39] A surface engineering method was developed for biodegradable magnesium alloys to enhance orthopedic implants.[40][41]
