Which activity is often recommended for patients with osteonecrosis as part of their initial treatment?

Range of motion exercises are often recommended as part of the initial treatment for patients with osteonecrosis due to their focus on maintaining joint flexibility and function without placing excessive stress on the affected area. Osteonecrosis, a condition characterized by the death of bone tissue due to a lack of blood supply, can lead to joint pain and decreased mobility.

Incorporating range of motion exercises helps to minimize stiffness, improve circulation around the joint, and maintain joint function, which is crucial for patients dealing with this condition. These exercises are typically low-impact and can be tailored to the individual's needs, making them a safe and effective choice during early treatment.

In contrast, activities like aggressive weight lifting, high-impact aerobic activity, and long-distance running could exacerbate the symptoms or lead to further damage to the affected joint, making them unsuitable for initial management of osteonecrosis.
