Kernrechtsfrage
Whether the bilateral knee complaints were in a natural causal relationship to the 1977 military accident.
Extrahierter Entscheid
The knee complaints were not shown, with the required degree of probability, to be naturally causally linked to the 1977 accident.
Extrahierte Begründung
The medical record did not establish a probable causal connection; early and intermittent references to knee symptoms were insufficient, long symptom-free periods intervened, and the most persuasive medical opinions characterized the complaints as likely degenerative rather than accident-related.
