Iliopsoas tendonitis and Iliopsoas Syndrome

• Iliopsoas tendonitis is inflammation of the iliopsoas muscle which can also affect the bursa lying under the iliopsoas muscle tendon.  
• Iliopsoas syndrome is a stretch, tear or complete rupture of the iliopsoas muscle and/or iliopsoas tendon.
• The iliopsoas muscle and tendon are commonly injured from acute trauma and/or overuse resulting from repetitive hip flexion.
• The pain may radiate down the anterior thigh to the knee.
• One variant is the internal snapping hip syndrome which results in an audible snap or click in the hip or groin with hip flexion.
• Treatment consists of rest, stretching exercises, physical therapy and NSAIDs.
