Looking for some info, guys.<br /><br />I have a service connected disability (knee @ 10%) that the government has paid me a pension for the last 13 years. Recently I found that I am going to need surgery on it, as it has deteriorated over the years. They want to scope it first, then they will make the decision as to if they are going to replace the ACL again or do a complete knee reconstruction/replacement.<br /><br />My question is this...the VA and I have already agreed to the 10% disability 13 years ago, and the knee has gotten worse, can I resubmit paperwork to get the % upped, or am I locked in for life at 10%?
