Referral patterns of hip pain in patients undergoing total hip replacement.
This study was undertaken to determine the most common referral patterns of hip pain in patients scheduled to undergo primary and revision total hip replacement. The exact location of pain from the hip was recorded prospectively for 323 patients (358 hips) who had primary total hip replacement and for 94 patients who had revision of a loose total hip. Seventy-three percent of patients with primary hip disease had pain in the groin, and 27% had groin pain that referred to the knee. Eighty-nine percent of 57 patients who had femoral component loosening had thigh or knee pain, and all of the 34 patients who had a loose acetabular component with a well-fixed femoral implant had pain in the hip region without distal radiation of pain. These results indicate that in patients who have a painful total hip, thigh pain is highly suggestive of femoral component loosening and pain located around the hip region that does not radiate distally is associated with isolated acetabular component loosening.
