Questione giuridica chiave
Whether the impairment compensation for the 1999 accident had to be increased beyond 20% because of the knee prosthesis and alleged worsening.
Decisione estratta
No. The court held that the insurer correctly fixed the integrity impairment at 20% and no further compensation was due.
Motivazione estratta
The assessment had to be based on the uncorrected state before the prosthesis. The competing medical opinion relied mainly on the insured's subjective complaints and on the post-prosthesis situation. No medically established aggravation, instability, or durable additional impairment warranting a higher percentage was shown.
