The Board has determined that the Veteran's right knee disability, including osteoarthritis and a meniscus injury, was not incurred in or aggravated by active military service. The preexisting condition of a right knee arthroscopic surgery is considered to have existed prior to service and did not increase in severity during service. Osteoarthritis is deemed the natural progression of the pre-existing right knee injury/treatment combined with post-service obesity and occupational bending.
The deciding factor: The VA examiner concluded that the sum effect of the appellant's preexisting right knee injury/treatment, post-service obesity, and the additional risk factors for knee osteoarthritis (occupational bent knee activities) was clear and unmistakable evidence that any increase in disability was due to the natural progression of the pre-existing disease.
