first of all iam appreciating your thought
her leg is like this since the acciedent,she is 30yr,with grade 4 of the Rt and the Lt with grade 1.she is not resisting the movment and all investgation came -ve.we take her to x-ray and show narrowing of the joint nothing else.now we refer her to orthopedic surgen.

iam thinking now about your idea,it can be right because she is severly depressed following her lost of her husband in that accident
