As the title says I have arthritic knees and I am about to try the "gel" injections to help with that. My ortho doesn't want me to do squats and 10 years ago I would just ignore him and let my ego tell me what to do, but being 46 and not 36 I am going to try to follow his advise. My question is has anyone tried to substitute anything for squats? I really want to give this a go, but I also want to be able to golf and hike up and down mountains in 20++++years to hunt and fish. I am open to any and all thoughts for consideration.
