The Board has determined that the veteran's degenerative arthritis of the right knee is secondary to his service-connected left knee disability and grants this claim. The bilateral ankle disability issue remains pending as it requires further examination.

The Board denied service connection for multiple disabilities, including bilateral wrist, ankle, foot, shoulder, allergic rhinitis, sinusitis, lumbosacral spine, and carpal tunnel syndrome, as the evidence did not support a finding that these conditions were related to active service.

The Board granted service connection for multiple conditions, including bilateral foot disability, knee disability, ankle disability, cervical degenerative disc disease, spondylosis, and cervicalgia, secondary to a service-connected lumbar strain, as well as GERD. The claims of readjudication were also granted.

The Board denied service connection for multiple conditions, including fatigue, bilateral eye disability, hypertension, diabetes mellitus, GERD, penile condition, left foot disability, and others. Some claims were remanded for further development.

The Board denied service connection for hypertension, sinusitis, chronic fatigue syndrome (CFS), a cervical spine disability, a bilateral ankle disability, a bilateral knee disability, and a bilateral shoulder disability as there was no evidence of current diagnoses or medical nexus to active service.
