In this report, we describe a case of @entity1642 over 6 months in the bilateral knees of an individual with @entity11810 . An 87-year-old @entity1 complained of spontaneous @entity158 in her right knee. A plain X-ray did not show any lesions at the time; however, 2  weeks later, a slightly displaced supracondylar @entity174 was observed. The @entity174 was treated with a long leg cast for 6  weeks. The @entity1 was able to walk with a walker 12  weeks after the injury, but her right thigh muscles had atrophied. Four months after the first injury, she suffered left knee @entity158 . Magnetic resonance imaging (MRI) showed an undisplaced supracondylar @entity174 of the left femur. After undergoing the same treatment as for the previous @entity174 for 8  weeks, she complained of @entity158 in the proximal tibia, and a @entity174 in the lateral tibial plateau was observed by MRI. No @entity3018 were found by imaging or laboratory studies. Her bone mineral density was found to be low, and she was diagnosed with @entity1642 due to @entity11810 . The work overload on the healthy side induced by @entity425 on the affected side may have caused the subsequent insufficiency @entity174 on the healthy side. These findings suggest that one should pay attention to and treat lower limb @entity2057 when managing insufficiency @entity174 of the lower limbs.
