Dear Editor,Stress fractures are caused by repeated micro trauma to the bone over a period of time. It can happen in normal bone exposed to abnormal repetitive stress or in abnormal bone receiving normal stress. In healthy individuals, tibia stress fractures occur most frequently amongst athletes who participate in activities that involve prolonged walking, running or jumping. 1 The tibia shaft is most commonly affected, whereas the proximal tibia is less common. 2 Risk factors include excessive training, alteration in normal gait biomechanics such as tightness of calf muscles, unequal leg length, osteoporotic bone and vitamin D deficiency. 3,4 This type of fracture can be easily misdiagnosed due to its clinical presentation and location near the knee, 5,6 which can mimic medial-sided osteoarthritis, meniscal injuries and pes anserinus bursitis. We describe an atypical presentation of atraumatic proximal tibia stress fracture in a young healthy male with no known risk factors.
