well the VA sent me a letter that I did not have a knee replacement even thought they had the full documentation of it and the had given me the rehab 100% so started that battle back in early september with no word yet. I also refiled for my hearing and tinnitus. I had the appointment with the ear dr today after the tests he said I do have hearing loss with ringing and it is due to noise exposure and he recommended hearing aids from the VA and whatever compensation they give. Last time they acknowledged the Ear problems but said there was no proof it was service connected. I also submitted numerous hearing tests from when I was active duty that noted the loss and tinnitus ( I worked the deck as a AT troubleshooter final checker in A-6 intruder squadrons for most of my 20 years in) as of right now I have 20 % 10 for each knee but the right one has had A TOTAL knee replacement which is a minimum of 30 % so when i will all of these i should be between 50 and 60 % and finally not have it taken from my retirement check Please wish me luck
