Hi! I hope your mom is doing really well. My mom had both knees done and it is thebest thing she ever did...she is 71 and can do what she has never been able to do with her grandkids...get on the floor and play with them. It took somewhere in the area of a year or so to heal completey and to get used to the new material in the knees, but she is really hapy she did it. I wish we could convince my mother in law to get it done....she is a mess.

Take care and I wish you all the best with you and your mom!!!!!!!!!!!!!!!
