Daphne17, thank you for your reply. I know it will have to have something more. The bone graft broke and the plate was temporary. I did not know that since I'm now under another Dr. That seems to know just what he's talking about. I was left with a very stiff knee from tnr so it was add already stiff now my bend is maybe 50. So hopefully rod will strengthen my left leg and knee. It's very weak and I've had lots of thearpy and more to come. I am just praying I make right decision. Again thank you so much.
