Background: Stress fractures are microscopic fractures caused by repetitive cumulative micro trauma on the bone over a period of time. Stress fracture is seen to occur in military personnel and sports persons who indulge in intense physical activity. It causes morbidity, economic loss and long periods of absence from duty and training. Tibia stress fractures are more commonly unilateral and are usually in the diaphyseal portion of the tibia. Case Report: We present a case of bilateral symmetrical synchronous stress fractures of medial condyles of bilateral tibia in a military man. X-ray, computed tomography and MRI of the knees revealed the stress fractures. A symmetrical and synchronous presence of stress fractures in the lower limbs is unusual. Conclusion: Radiological investigations are conclusive in cases of stress fractures. In case of unilateral stress fracture, contralateral side should also be investigated to diagnose bilateral injury.
