Medication
Physical therapy, to help decrease joint tenderness and stiffness, and to increase the joint’s range of motion. Use of a cane or crutches, to provide support and help relieve pain and weakness when walking. Most people with osteonecrosis eventually need surgery to repair the bone as the disease gets worse.
Procedures
Osteonecrosis is a bone disease. It results from the loss of blood supply to the bone. Without blood, the bone tissue dies.
Therapy
Bone loss due to osteonecrosis may be painful, especially in the hip and knee joints, which bear much of the body’s weight. Nonsteroidal anti-inflammatory drugs, or NSAIDs, work by reducing inflammation in the soft tissues surrounding the joint, relieving pain and swelling.
Self-care
A biopsy is a surgical procedure in which tissue from the affected bone is removed and studied. It is rarely used for diagnosis, as the other imaging studies are usually sufficiently distinct to make the diagnosis with a high level of confidence. Appropriate treatment for osteonecrosis is necessary to keep joints from collapsing.

What happens when bone tissue dies?
Avascular necrosis is the death of bone tissue due to a lack of blood supply. Also called osteonecrosis, it can lead to tiny breaks in the bone and cause the bone to collapse. The process usually takes months to years. A broken bone or dislocated joint can stop the blood flow to a section of bone.
What causes lack of blood flow to bones?
Avascular necrosis is a disease that results from the temporary or permanent loss of blood supply to the bone. It happens most commonly in the ends of a long bone. Avascular necrosis may be the result of injury, use of medicines, or alcohol. Symptoms may include joint pain and limited range of motion.
What medication causes osteonecrosis?
Bisphosphonates — such as alendronate (Fosamax, Binosto), risedronate (Actonel, Atelvia), ibandronate (Boniva) and zoledronic acid (Reclast, Zometa) — and denosumab (Prolia, Xgeva) have been linked to osteonecrosis of the jaw and atypical femoral fractures.

What is osteonecrosis made of?
What is osteonecrosis? Your bones are made up of living cells that need a blood supply to stay healthy. In osteonecrosis, blood flow to part of a bone is reduced. This causes death of bone tissue, and the bone can eventually break down and the joint will collapse.

What happens when avascular necrosis is blocked?
Avascular necrosis happens when something blocks the flow of blood to your bone tissue. Your bones are constantly changing as your skeletal system makes new bone tissue to replace aging bone tissue that eventually breaks down and dies.
Why does the body make new bone tissue?
Think of this as a cycle — your body makes new tissue to replace the tissue that’s breaking down and dying. This pattern needs to happen correctly to keep your bones healthy and strong. Blood carries the nutrients and oxygen bones need to stay healthy and regenerate. Without blood flow, your skeletal system can't make new bone tissue fast enough. The dying bone begins to crumble and eventually collapses.

What is osteonecrosis?
Osteonecrosis, also known as avascular necrosis (AVN), aseptic necrosis or ischemic bone necrosis, is a disease resulting in the death of bone cells. If the process involves the bones near a joint, it often leads to collapse of the joint surface and subsequent arthritis due to an irregular joint surface.
How does osteonecrosis affect the body?
In the early stages of osteonecrosis, 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 osteonecrosis progresses and the bone and surrounding joint surface collapse, pain may develop or increase dramatically. Pain may be severe enough to cause joint stiffness by limiting the range of motion in the affected joint. Disabling osteoarthritis may develop 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.
What causes bone cell death?
Osteonecrosis has many different causes. Loss of blood supply to the bone may lead to bone cell death and can be caused by an injury (bone fracture or joint dislocation; called traumatic osteonecrosis). At times, there may be no history of injury (non-traumatic osteonecrosis); however, other risk factors are associated with the disease such as some medications (steroids, also known as corticosteroids), alcohol usage or blood coagulation disorders. Increased pressure within the bone also is associated with osteonecrosis. One theory is that the pressure within the bone causes the blood vessels to narrow, making it difficult for blood to circulate through the bone. Osteonecrosis can also be associated with other disorders. The exact reason osteonecrosis develops is not fully understood for some risk factors. Sometimes, osteonecrosis occurs in people with no risk factors (idiopathic). Some people have multiple risk factors. Osteonecrosis most likely develops because of the combination of factors, possibly including genetic, metabolic, self-imposed (alcohol, smoking), and other diseases that you may have and their treatment.
What bone is affected by osteonecrosis?
Although it can happen in any bone, osteonecrosis most commonly affects the ends (epiphysis) of long bones such as the femur (thigh bone). Commonly involved bones are the upper femur (ball part of the hip socket) the lower femur (a part of the knee joint), the upper humerus (upper arm bone involving the shoulder joint), and the bones of ankle joint. The disease may affect just one bone, more than one bone at the same time, or more than one bone at different times. Orthopedic surgeons most often diagnose the disease using either an X-ray of magnetic resonance scan (MRI).
What happens if you leave a bone untreated?
If left untreated, the disease progresses, and the bone may develop a crack whereby the bone can get compressed (collapse) together (similar to compressing a snowball). If this occurs at the end of the bone, it leads to an irregular joint surface, arthritic pain and loss of function of the affected areas.
How to determine the best treatment for bone and joint disease?
To determine the most appropriate treatment, the doctor considers the following aspects of a patient’s disease: the age of the patient; the stage of the disease–early or late; the location and amount of bone affected–a small or large area. The underlying cause has not been shown to influence outcomes of treatment.
Which imaging is the most sensitive for osteonecrosis?
Research studies have shown that magnetic resonance imaging (MRI) is currently the most sensitive method for diagnosing osteonecrosis in the early stages. The tests described below may be used to determine the amount of bone affected and how far the disease has progressed. X-Ray.

What is the condition called when you have a bone in your knee?
This condition is called osteonecrosis, which literally means "bone death.". In the knee, the knobby portion of the thigh bone on the inside of the knee is most often affected. However, osteonecrosis of the knee may also occur on the outside of the knee or on the flat top of the lower leg bone.
What happens to the articular cartilage when the bone is in stage 4?
The articular cartilage covering the bone begins to loosen as the bone itself begins to die. Operative treatments may be considered at this point. Stage IV: At this point, the bone begins to collapse. The articular cartilage is destroyed, the joint space narrows, and bone spurs may form.
Can osteonecrosis be caused by steroids?
Steroid-induced osteonecrosis frequently affects multiple joints and is usually seen in young patients. Regardless of the cause, if the disease is not identified and treated early, it can develop into severe osteoarthritis.
What kind of doctor treats osteonecrosis?
