The Veteran's claims for increased ratings and service connection were denied based on the evidence of record.

The Board denied a rating in excess of 30 percent for the Veteran's total left knee replacement, finding that it resulted in at most intermediate degrees of residual weakness, pain, or limitation of motion.

The Board denied the veteran's claims for increased ratings for left knee instability, left knee arthritis, right shoulder strain, and residual scars to the right shoulder, index finger, and long finger.

The Board granted service connection for a left foot disability (other than callosities) and a right hip disability, as well as increased ratings for an acquired psychiatric disorder, bilateral foot disability prior to July 6, 2020, lumbar spine disability, right knee instability prior to October 2, 2019, and left knee instability. However, it denied increased ratings for the bilateral foot disability since July 26, 2020, right knee arthritis, left knee arthritis, and right knee instability since October 2, 2019.

The Board is remanding the matters for clarification from the private examiner as to whether a goniometer was used, and will defer further adjudication until such clarification is provided.
