Q. Can 3-D printing be used for creating artificial hips and knees for joint replacement?
Doctor Answer is medically reviewed by SecondMedic medical review team.
Absolutely! 3-D printing technology has already been used to create a number of medical implants, such as artificial hips and knees for joint replacement surgery. This is a rapidly advancing field, and the potential for further applications in healthcare is immense.
In fact, 3-D printing can be used to make custom designed hip and knee replacements that are tailored specifically to an individual patient's anatomy. Using these personalised implants offers many advantages – they fit more securely than traditional implants, improving stability; they result in quicker healing times; and they have the potential to minimise postoperative complications. Additionally, 3-D printed prosthetics don’t require the same costly moulds or tools needed by traditional manufacturing processes, making them much more cost effective overall.
3-D printing is also being explored as a way to improve other types of medical devices. For example, researchers at Vanderbilt University recently created an implantable device using layers of carbon nanotubes printed onto flexible plastic substrates – this type of implant could help restore nerve signals in patients with spinal injuries or paralysis. Similarly, researchers at Princeton University have developed soft robot actuators made from 3-D printed hydrogel materials – these could be used for drug delivery systems or even surgical robotics!
Clearly there are some exciting applications for 3-D printing in the world of medicine – with further advances in the technology we can only expect it will become even more widely used across a variety of different treatments and procedures.
