We all know that vitamins are good for your body. But did you know that vitamins can even make orthopedic implants last longer? Artificial joints are incredibly well-made and can last a very long time — often more than 30 years. However, like any mechanical part, they can start to wear out over time. Usually, the plastic liner in the joint is the weak link. This plastic is typically made of cross-linked polyethylene, a material similar to what kitchen cutting boards are made from. The exciting news is that implant companies are now creating a new type of plastic that could last even longer!
A recent article in the Journal of Shoulder and Elbow Surgery highlights how vitamin E is being used to make better plastics for shoulder implants. The study tested a new type of polyethylene that has vitamin E added to it and compared it to the standard type of plastic. Scientists put these materials through intense wear simulations — kind of like putting them on a treadmill to see how long they would last. The results were impressive: the vitamin E-enhanced plastic showed much less wear than the regular plastic.
So, why does vitamin E make a difference? When plastic is exposed to wear and tear, it can release tiny particles that may irritate the bone and cause problems like loosening of the implant. Vitamin E acts like a shield, reducing the breakdown of the plastic and lowering the risk of these issues. This means the new plastic could help joint replacements stay in great shape for even longer.
While we still need more long-term studies to see how these implants perform in real people over decades, the early results are very promising. Many companies are already starting to include vitamin E-enhanced plastics in their implants, giving surgeons and patients more options to choose from. This is an exciting step forward in improving a procedure that has already changed so many lives for the better.
