Is it advisable to do exercise when affected by Osteonecrosis? Which activities would you suggest and how intense should they be?

Exercise is generally recommended for individuals with Osteonecrosis, provided it is low-impact and performed under medical guidance to avoid excessive stress on compromised joints. While physical activity is essential to maintain muscle strength and mobility, patients must strictly avoid high-impact activities that could accelerate bone collapse in areas affected by Osteonecrosis.

Is exercise safe for someone with Osteonecrosis?

For the 410 members of the DiseaseMaps community living with Osteonecrosis, movement is a double-edged sword. While inactivity leads to muscle atrophy and stiffness, excessive load on a necrotic joint can worsen structural damage. Exercise is safe and beneficial only when it minimizes weight-bearing stress on the affected bone, helping to manage pain and improve cardiovascular health without jeopardizing joint integrity.

Which physical activities are recommended for Osteonecrosis?

Focus on non-weight-bearing or low-impact exercises that preserve joint range of motion. The following activities are typically well-tolerated:

• Swimming and Water Aerobics: Buoyancy reduces gravitational pressure on the hip or knee, making this the gold standard for Osteonecrosis management.


• Stationary Cycling: Provides mobility without the impact of road cycling.


• Gentle Yoga or Pilates: Excellent for flexibility, provided you avoid poses that place full body weight on the affected joint.


• Seated Strength Training: Using resistance bands to maintain muscle mass around the affected area.

What activities should be avoided?

To prevent the progression of Osteonecrosis, strictly avoid high-impact activities such as running, jumping, contact sports, or lifting heavy free weights that place direct vertical pressure on the affected limbs. If you experience sharp, localized pain during any movement, stop immediately; "no pain, no gain" does not apply to Osteonecrosis.

How can I start an exercise program safely?

Before beginning any regimen, consult an orthopedic surgeon to determine the stage of your Osteonecrosis. A physical therapist is essential for creating a customized program that includes "pacing"—performing shorter, more frequent sessions rather than one intense workout—to manage fatigue and joint stress effectively.

Next steps

• Obtain clearance from your orthopedic specialist regarding your specific stage of bone involvement.


• Request a referral to a physical therapist experienced in treating bone-related pathologies.


• Join the DiseaseMaps Osteonecrosis community to share experiences with others managing activity levels.


• Monitor your symptoms using a pain diary to identify which movements improve or worsen your condition.
