Arthroplasty is a common procedure in orthopedic surgery to address severe osteoarthritis (OA) in the hip joint. With the burgeoning “baby boomer” generation and older athletes who wish to return to competitive levels of sports, understanding how sporting activity affects arthroplasty outcomes is becoming exceptionally important. The demand for total joint arthroplasty is projected to increase in the first three decades of the twenty-first century. Patients who have had a hip or knee replacement are more and more expecting to participate in athletics after rehabilitation.
