Barnes, William v. Jack Cooper Transport Co.
In this interlocutory appeal, the Tennessee Workers’ Compensation Appeals Board reviewed a case involving William Barnes, an employee who sustained a left knee injury at work, exacerbating pre-existing osteoarthritis. The employer, Jack Cooper Transport Co., and its current insurer, National Interstate Insurance Company, denied authorization for a total knee arthroplasty, arguing it was related to pre-existing conditions rather than the recent 2018 work incident. The trial court initially ordered authorization, but the Appeals Board reversed this specific order. While affirming the provision of reasonable and necessary medical benefits causally related to the 2018 injury, the Board found that the preponderance of medical evidence, particularly from the authorized treating physician Dr. Garside, did not support the conclusion that the 2018 incident was the primary cause (contributing more than 50%) for the need of the total knee arthroplasty, outweighing the opinion of Dr. Jones which the trial court credited.
