It is particularly seen in the last trimester of the pregnancy and remission occurs spontaneously at the postpartum period. This disorder frequently affects the hip joint, while it may rarely migrate to the knee, ankle, and the foot joints. In this article, we report a 35-year-old female case who had transient osteoporosis of the hip at the last trimester of her pregnancy and showed migration to the bilateral knee after childbirth. While spontaneous recovery of the disorder in the postpartum period was expected, transient osteoporosis interestingly advanced to her knee joints in our case. To the best of our knowledge, this is the first case of the migration of transient osteoporosis to the knee joint in the postpartum period.
