Femoral Acetabular Stress Injury

A femoral acetabular stress injury is bone stress around the hip joint caused by repetitive loading. It may cause deep groin pain that worsens with impact activity.

Frequently Asked Questions

What is a femoral acetabular stress injury?

A femoral acetabular stress injury is an overuse injury involving stress around the hip joint where the thigh bone meets the socket. It can cause deep hip or groin pain during activity. Early recognition is important because continued loading can worsen the injury.

What causes a femoral acetabular stress injury?

It is usually caused by repetitive impact or high training loads. Running, jumping, military training, and sudden increases in activity can increase risk. Bone health, nutrition, and recovery time also matter.

What are the symptoms?

Symptoms often include deep groin or hip pain that worsens with activity and improves with rest. Pain may become more constant if the injury progresses. Limping or pain with weight bearing should be evaluated.

How is it treated?

Treatment usually includes stopping painful impact activity and protecting weight bearing if needed. Physical therapy helps address strength, mobility, and mechanics once pain improves. Imaging may be needed to determine severity.

When can I return to sports?

Return depends on healing, pain-free walking, and gradual tolerance to loading. Many stress injuries require several weeks to months before full return. Progression should be gradual to avoid worsening or recurrence.
