Hip impingement, or femoroacetabular impingement (FAI), occurs when extra bone growth on the hip socket or femur causes the joint to pinch and rub. This can result in symptoms such as hip or groin pain, stiffness, catching, or limited range of motion. For runners, the repetitive hip flexion and rotation inherent to each stride can exacerbate these symptoms, particularly during higher mileage or faster training blocks. Not all runners with FAI experience pain, but when symptoms arise, addressing

Femoroacetabular impingement (FAI) occurs when there is abnormal contact between the femoral head and the acetabulum, leading to pain and restricted hip movement. It is classified as cam, pincer, or mixed-type impingement. Patients often experience hip or groin pain, stiffness, and discomfort with deep flexion or prolonged sitting. Diagnosis is based on clinical assessment and imaging, such as X-rays or MRI. Treatment depends on symptoms and severity. Conservative management includes activity mo
