Transient osteoporosis is a rare self-limited condition that affects mostly middle-aged men or women in the third trimester of pregnancy. The most commonly affected joint is the hip, while bilateral involvement of the knees is extremely rare. Complete resolution of symptoms and MRI findings occurs over 8 to 10 months after clinical onset. We present a case of a 40-year-old woman diagnosed with bilateral transient osteoporosis of the knees, in the early postpartum period treated for 6 months with calcitonin, analgesics and physiotherapy.
