What are the symptoms of avascular necrosis?

In the early stages of avascular necrosis, patients may not have any symptoms. As the disease progresses, however, most

patients experience joint pain - at first, only when putting weight on the affected joint, and then even when resting. Pain usually develops gradually and may be mild or severe. If avascular necrosis progresses and the bone and surrounding joint surface collapses, pain may develop or increase dramatically. Pain may be severe enough to limit the patient’s range of motion in the affected joint. The period of time between the first symptoms and loss of joint function is different for each patient, ranging from several months to more than a year. In the course of avascular necrosis, however, bone tissues break down faster than the body can repair them. In the early stages of avascular necrosis, patients may not have any symptoms.
