Three Cases of Ipsilateral Limb Swelling Secondary to Iliopsoas Bursitis Following Total Hip Arthroplasty

This article reports three cases of ipsilateral limb swelling following total hip arthroplasty secondary to vascular compression from iliopsoas bursitis. The etiology was attributed to insufficient acetabular component anteversion, leading to polyethylene liner wear and iliopsoas impingement. Two patients underwent revision surgery and achieved symptom resolution. In contrast, the third patient opted for conservative management, resulting in recurrent limb swelling and the development of deep vein thrombosis. The patient required interventional treatment by the vascular surgery service and ultimately showed clinical improvement.
