GOod luck Sheeriquilts. My mom had both her done at the same time a few year back and she did well. This time replaced the right knee again. Just be sure after you have it done to let any doctors know, incl. the dentist, you have implants, she forgot she had them and had a dental procedure and got a bad infection in her knee, hence this second one. This way you have a heads up. DOn't be nervous. We will have you in our thoughts and prayeres too. Hope you have someone who can keep us up to date.
