What is...
Adductor tubercle on the medial condyle. Over rotation, less superimposition of fibular head. Under rotation, more superimposition of fibular head.

What is...
Proximal femur (hip) fracture
Osteroporosis- loss of bone mass from metabolic or other factors.
Avascular necrosis- loss of blood circulation and cell death.
Both lead to weakening or collapse of weight bearing joints (hip joint).
