Is a little pus on my partial knee replacement sight where the stitch is anything to be concerned about a month after surgery?

Yes. Yes it requires good local wound care. Clean it several times each day with hydrogen peroxide and cover and change bandaid regularly. This is usually a stitch that is working its way to the surface. Check with your doctor and you may need antibiotics to help clear the area up.
Yes,see your surgeon. "pus" at a surgery site always potentially concerning. It could be something relatively minor such as a buried absorbable stitch irritating the skin, or it could be a very serious problem of a deep infection in the joint. Only your surgeon should make that call and do it asap!

Uncommon, age. If the partial knee replacement is performed correctly, one should expect it to last for many years. At the age of 38, you still need to avoid running for excercise, just as for a full knee replacement. If indicated, much better option for you at your very young age. Read more...
