The Board has granted service connection for the Veteran's right knee osteoarthritis, finding that it is related to his in-service combat-related injuries. The claim was reopened due to new and material evidence received since the last denial.

The Board granted service connection for obstructive sleep apnea (OSA) as secondary to the Veteran's service-connected hypertension and an earlier effective date of May 14, 2018, for radiculopathy right lower extremity. Other claims were denied.

The Board denied service connection for obstructive sleep apnea and erectile dysfunction, but granted an increased rating of 40 percent for a low back disability (intervertebral disc syndrome) and 20 percent for bilateral lower extremity radiculopathy.

The Board granted service connection for adjustment disorder with mixed anxiety and depressed mood, but denied service connection for sinusitis. The Board also granted initial ratings of 20%, 30%, and 70% for right knee osteoarthritis, left knee osteoarthritis, and adjustment disorder with mixed anxiety and depressed mood, respectively.

The Board granted service connection for allergic rhinitis and denied service connection for left ear hearing loss, while dismissing the appeal for sinusitis. The claims for initial disability ratings for acute bronchitis and right knee osteoarthritis were remanded.
