Key legal question
Whether the March 3, 2008 knee event was an accident or accident-like bodily injury
Extracted holding
The event was not shown to be an accident and the diagnosed knee arthrosis was not an accident-like bodily injury.
Extracted reasoning
The complaint did not challenge the lower court's finding that the event lacked an unusual external factor, and arthrosis does not qualify as an accident-like bodily injury under the relevant provisions.
