A 56-year-old man visits his GP due to hip discomfort. He reports that it has been gradually worsening for the past three months. The pain is constant throughout the day and night, but it is most severe when he puts weight on it. He denies experiencing any morning stiffness. He has attempted to alleviate the pain with paracetamol and ibuprofen, but to no avail. The patient’s medical history includes active Crohn’s disease, which is being treated with corticosteroids. During the examination, there is tenderness when palpating the anterior groin area, but the range of passive motion is normal. What is the most probable diagnosis?
