Patient: Can osteonecrosis of the femoral head be completely cured? Is it better to be more active or less active with osteonecrosis of the femur? And why does the knee hurt so much? Patient: Can ischemic osteonecrosis of the femur be cured? How long does it take to walk? Can it be cured without surgery? Doctor: Ischemic necrosis of the femoral head is a difficult disease to cure, many orthopedic surgeons at home and abroad are trying to find ways to treat this disease, but so far, there is no 100% effective treatment. Conservative treatment of just taking drugs has the worst effect, only relieving the symptoms, with little possibility of recovery. Various head-preserving surgeries have some efficacy before the femoral head collapses, and some (40% – 50%) patients are able to recover because of the surgery and do not need other surgeries, but there are still some patients who cannot fully recover. For patients with early ischemic necrosis of the femoral head (stage 2 or less), decompression implant support surgery (allograft fibula or metal tantalum rod grafting) is generally used and can lead to healing in some patients with early osteonecrosis. Please bring your clinical information to the outpatient clinic for specific recommendations on whether you are a candidate for early head preservation surgery.
