Questão jurídica principal
Whether the claimant's health had materially worsened since the 2004 MEDAS report so as to justify reconsideration of the pension claim.
Decisão extraída
The cantonal court's factual finding was incomplete and partly contrary to the record, especially regarding new knee findings; further medical clarification was required.
Fundamentação extraída
The file showed new orthopedic diagnoses after the MEDAS report, and the treating physician had expressly linked advanced knee disease to work capacity. These findings could not be ignored, and they might affect the invalidity degree.
