Key legal question
Whether the insured's right-knee condition remained causally related to the 2010 accident
Extracted holding
The knee complaints were no longer in natural causal connection with the accident; they resulted from pre-existing degenerative disease.
Extracted reasoning
Medical reports showed pre-existing gonarthrosis, no fresh post-traumatic lesion after the fall, and the current evolution matched the natural progression of advanced degenerative changes and obesity.
