Questione giuridica chiave
Whether the left-knee complaints reported in 2006 were caused by a service-related injury or were late consequences of the 1993 military service episode.
Decisione estratta
The required natural and adequate causal link was not established with predominant probability.
Motivazione estratta
The contemporaneous medical records showed only a worsening of a pre-existing condition during service, not a documented structural knee injury; the later expert opinion relied on an inaccurate history and did not prove continuing effects of a service injury.
