Questão jurídica principal
Whether the right-knee arthritis and resulting knee-prosthesis surgery were predominantly caused by the 1978 accident.
Decisão extraída
The causal link was not shown with the requisite probability; the right-knee condition was not attributable to the accident.
Fundamentação extraída
The court accepted the comprehensive expert report and supplemental report as convincing and consistent. The medical records showed no decisive arthrosis signs in the years immediately after the accident; the 1984 imaging did not demonstrate osteochondral changes sufficient to establish accident causation.
