Questão jurídica principal
Whether the pension entitlement from 14 February 2011 required further medical assessment and a recalculation of invalidity.
Decisão extraída
The record was insufficient for the period from 14 February 2011 onward; the case had to be remitted for further expert medical clarification.
Fundamentação extraída
The later knee complaints could neither be reliably linked nor excluded as accident-related on the existing file. Prior medical opinions did not address the later deterioration, while a later opinion suggested probable accident causality without explanation.
