Key legal question
Whether the knee lesions were covered as an accident or an accident-like bodily injury caused by the Nordic walking incident.
Extracted holding
The event was only an accident-like occurrence if the claimant proved that the meniscus tears and ACL rupture were caused by the stumble; that proof failed.
Extracted reasoning
A mere stumble is not an unusual accident, but it can be an external event. Here, however, it was not established with predominant probability that the diagnosed lesions were caused by the incident.
