The Veteran's increased rating claims for left hip arthritis, right thigh scar (as a residual of a right knee gunshot wound), and right knee gunshot wound residuals were denied. The Veteran was not granted any additional disability evaluations.

The Veteran's service-connected lumbar spine and associated bilateral lower extremity radiculopathies rendered him unable to secure or follow substantially gainful employment from June 30, 2006, onward. The Board granted a 20% disability rating for the period on appeal (not including any periods of convalescence) due to severe muscle spasm and guarding resulting in abnormal gait or spinal contour.

The Board has determined that the AOJ's decision denying service connection for OSA, claimed as secondary to service-connected psychiatric disorder and DDD of the lumbar spine, is flawed due to a failure to consider whether obesity was an intermediate step in the development of OSA. The case is being remanded to obtain an addendum medical opinion.

The Veteran's PTSD symptoms more nearly approximate the criteria for a 70 percent rating, warranting an increased rating.,Service connection for lumbar degenerative disc disease (DDD) and degenerative arthritis is remanded due to insufficient evidence in the record.,The Veteran's current employment status does not affect his entitlement to service connection for DDD and degenerative arthritis.

The Veteran's knee and hip conditions have been rated based on their current functional impairment, with some issues granted ratings while others are denied. The Veteran received separate maximum schedular ratings for his right knee meniscus tear residuals and left knee instability.
