Kernrechtsfrage
Whether the cantonal court correctly held that only the left-knee complaints were accident-related and that no further natural or adequate causal link existed for shoulder, back, and psychological complaints.
Extrahierter Entscheid
The cantonal court's assessment was upheld; only the knee complaints remained compensable.
Extrahierte Begründung
The medical records convincingly showed that only the first accident caused compensable knee complaints, while shoulder and back complaints lacked natural causation and psychological complaints lacked adequate causation.
