dman001948,Detonator,
Both of you need to get a IMO.......this must come from a ortho doctor.
I left service with a R knee mess..Miniscus tear , anterior Cruciate Ligament....for years the VA low balled me, I wised up and started using a private ortho, I now have a rating of 30% with additional 10% for arthritis, with 10% for ankle, 10% for hip,and a % for Back, not to mention other injuries not due to the knee.
If you have a problem make your doctor connect the dots,the VA will not do it for you as the burden of proof is yours.
