Kernrechtsfrage
Whether the 2008-06-16 knee event qualified as an accident or accidental bodily injury under UVG/ATSG.
Extrahierter Entscheid
The insured failed to prove, with the required probability, an external factor such as a fall, other accident event, or externally caused bodily movement.
Extrahierte Begründung
The medical record did not establish a full patellar dislocation caused by an external trauma; the court accepted that only a lateral subluxation was shown and that prior, non-traumatic patellar episodes were likely. Further medical investigation could be omitted in anticipatory evaluation.
