Q. A 28-year-old man comes to your clinic with bilateral hip and groin pain for the past 3 months. He explains the pain as a constant, dull, achy pain at rest that is exacerbated by hip movement or weight bearing. He also has difficulty opening his legs and rotating his thigh internally and externally. The patient has had no recent falls or other trauma. Medical history is significant for systemic lupus erythematosus, diagnosed four years ago and treated with continuous low-dose prednisone and hydroxychloroquine. In physical examination, he has no active lupus skin lesion, swelling or inflammation in other joints, and no cushingoid findings. There is no redness, warmth, or tenderness over the hip joints, but decreased active and passive internal and external rotation, extension, and abduction in both hips are noted. Magnetic resonance imaging (MRI) of the hip joints is shown below. What is the best treatment approach for this patient?
