TRAUMATIC BILATERAL KNEE, BONE INFARCTIONS IN YOUNG MALE: AN UNUSUAL PRESENTATION OF MILD TO MODERATE GRADE TRAUMA ? A CASE REPORT

Osteonecrosis is a common complication of corticosteroid therapy. In this study, we report the case of a patient with trauma of both knees one year back who had been diagnosed with knee osteonecrosis involving bilateral tibial and femur probably due to microvascular injury. A 22-year-old male patient presented with a history of twisting injury of both knees for which he had not taken proper medical treatment and splintages to immobilize the limb. He was taking some analgesics by some medical practitioner after some time he develop gradual onset pain initially during work but after some time experienced in rest also located anteriorly in the knee. Magnetic resonance imaging performed on admission showed osteonecrosis of the bilateral proximal tibial and distal femur, almost equally pronounced. Osteonecrosis is a fairly common complication in patients with the history of corticosteroid use for the treatment of variety of systemic and rheumatic disorders but can also occurred due to trauma. The condition can manifest itself anywhere in the skeletal system, most commonly in the femoral head. Distal femur and proximal tibia with bilateral involvement is quite rare in the literature. Trauma of both knees and within one year gross osteonecrosis of bilateral knee joint is rarest presentation.
