Total hip arthroplasty is a highly successful treatment for end-stage arthritis that substantially improves patients' symptoms and function. Unfortunately, complications in the early postoperative period are inevitable, even in procedures performed by experienced surgeons using careful surgical techniques. Current strategies to prevent and effectively manage the most common early complications after total hip arthroplasty, including periprosthetic joint infection, instability, leg-length inequality, and periprosthetic femoral fracture, are discussed.
