Hi my name is Julianne, I'm 31, 6'1 and weigh 100kg. I have severe osteoarthritis, I had a tibial realignment on both knees in 2008. My cartlidge loss in the right is so bad it gives out constantly and I use a walker to walk inside and a
powerchair to go outside. If I build up my knee muscles with no cartlidge will that help? I was previously knock kneeded before surgery. I have panic attacks with my knees constantly giving out on me.
