Understanding Hip Impingement (FAI)
In FAI, the shape of the ball or socket causes them to rub abnormally during movement. Over time this can damage the labrum and cartilage, leading to pain and, in some cases, earlier arthritis.
Common Symptoms
- Groin pain, especially during or after activity
- Stiffness or discomfort after prolonged sitting
- Pain with deep bending or twisting
- Clicking or catching in the hip
Common Causes
- Cam impingement (ball shape abnormality)
- Pincer impingement (socket overcoverage)
- Combined structural factors
- Repetitive hip flexion in sport
How Assessment Works
Assessment includes history, examination of hip movement (impingement tests), X-rays to assess bone shape, and sometimes MRI to evaluate the labrum and cartilage.
Treatment Options
- Physiotherapy and activity modification
- Avoiding movements that provoke symptoms
- Ultrasound-guided injections for symptom relief
- Hip arthroscopy to address structural problems in selected cases
When to Seek Specialist Care
If you have persistent groin pain with activity or sitting, or symptoms that limit sport or daily life, a specialist assessment can help determine whether impingement is the cause.
Frequently Asked Questions
Does hip impingement always need surgery?
No. Many people manage symptoms with physiotherapy and activity modification. Surgery is considered when symptoms persist despite conservative care and imaging supports a structural problem.
Will hip impingement lead to arthritis?
FAI may contribute to the development of arthritis in some people over time. Assessment and appropriate management aim to reduce symptoms and protect the joint.
