Iliopsoas Tendonitis and Impingement After Total Hip Arthroplasty.

Iliopsoas impingement and tendinitis are a relatively uncommon but debilitating complication after total hip arthroplasty. Treatment for symptomatic iliopsoas pathology includes conservative management (nonsteroidal anti-inflammatories, ultrasound-guided corticosteroid injections, and physical therapy), iliopsoas tenotomy or fractional lengthening, and revision total hip arthroplasty with acetabular implant revision. Recognizing the etiologies of impingement as well as techniques and published outcomes of available treatment modalities is helpful in patient counselling, management, and optimization of clinical outcomes in symptomatic patients.
