The Board has determined that additional development is needed for the issues of an initial evaluation in excess of 10 percent disabling, separate evaluations for radiculopathy, and TDIU. The case will be returned to the Board after compliance with appellate procedures.

The Board remands the claims for an initial rating in excess of 10 percent for degenerative disc disease and associated radiculopathy, as the record does not include all relevant treatment records prior to back surgery.

The veteran was granted a total disability rating based on individual unemployability due to his service-connected disabilities.

The Board denied service connection for a back disorder, including degenerative disc disease, degenerative arthritis, spondylolisthesis, and compression fracture at L2, as the evidence did not support a finding that these conditions were incurred in or aggravated by service.

The Board granted service connection for right knee strain, left knee strain, lumbar radiculopathy of the right lower extremity, and lumbar radiculopathy of the left lower extremity. It also granted initial ratings for various disabilities including a 20 percent rating for lumbar degenerative disc disease with intervertebral disc syndrome, spondylosis, and spondylolisthesis, a 30 percent rating for labral tear, including superior labral anterior-posterior lesion, status post surgical repair, and higher ratings for other conditions.
