Reading on this page a lot knees seem to be something that the va downplays a lot. You can get three different ratings for knees and that should be a huge collection for your overall rating. Yet most people I see get 20-30% even with knee replacements. Am I wrong? What ratings do some of you guys have for your knees if you can share. For context my knees are gone gone, and I’m wondering after my exam if I’ll just be given a 20% for each and they call it a day.
