Which are the symptoms of Osteonecrosis?

Symptoms of Osteonecrosis

Osteonecrosis, also known as avascular necrosis, is a condition that occurs when there is a temporary or permanent loss of blood supply to the bones, leading to bone death. This can affect various bones in the body, but it commonly occurs in the hip, knee, shoulder, and ankle joints. The symptoms of osteonecrosis can vary depending on the stage and location of the affected bone.

Early Stage Symptoms

In the early stages of osteonecrosis, individuals may not experience any symptoms. However, as the condition progresses, the following signs may become noticeable:

• Pain: The most common symptom of osteonecrosis is pain, which may initially be mild and intermittent. As the condition worsens, the pain can become more severe and persistent.


• Stiffness: Joint stiffness, especially after periods of inactivity or rest, is another early symptom. This stiffness may gradually improve with movement.


• Joint discomfort: Some individuals may experience a feeling of discomfort or aching in the affected joint.

Advanced Stage Symptoms

If osteonecrosis progresses without treatment, the following symptoms may develop:

• Increased pain: The pain may become more intense and may occur even at rest or during nighttime, affecting sleep quality.


• Limited range of motion: As the condition worsens, the affected joint may become increasingly difficult to move, leading to a reduced range of motion.


• Joint collapse: In advanced stages, the bone may collapse, causing severe joint deformity and further impairing joint function.


• Cracking or popping sounds: Some individuals may experience cracking or popping sounds (crepitus) when moving the affected joint.


• Joint instability: The affected joint may feel unstable or give way, making it difficult to bear weight or perform daily activities.

Specific Symptoms based on Affected Bones

The symptoms of osteonecrosis can also vary depending on the specific bone affected:

• Hip: Hip osteonecrosis may cause groin pain that can radiate to the buttocks or thigh. Walking and weight-bearing activities may worsen the pain.


• Knee: Knee osteonecrosis can cause knee pain, swelling, and difficulty bending or straightening the knee.


• Shoulder: Shoulder osteonecrosis may result in shoulder pain, limited range of motion, and weakness in the affected arm.


• Ankle: Ankle osteonecrosis can cause ankle pain, swelling, and difficulty walking or bearing weight on the affected foot.

If you experience persistent joint pain or any of the mentioned symptoms, it is important to consult a healthcare professional for an accurate diagnosis and appropriate treatment. Early detection and intervention can help prevent further damage and improve outcomes.
