AC43617 - Malinowski v. Sikorsky Aircraft Corp. (Motion for articulation; expert opinion and medical probability; medical evidence; “On appeal, the defendant claims that (1) the board erred in affirming the commissioner’s finding that the workplace activities of the plaintiff, Richard Malinowski, substantially and permanently aggravated preexisting degenerative arthritis in his left knee, resulting in the need for a total knee replacement, and (2) the commissioner erred in failing to grant its motion for articulation. We affirm the decision of the board.”)
