Arthroplasty of the hip. Leg length is not important.

Author information

Victoria Hospital, Dunfermline, Scotland, UK.


Discrepancy in leg length after total hip replacement has been associated with patient dissatisfaction. We prospectively studied 200 consecutive patients undergoing unilateral Charnley hip replacements to identify whether there is a demonstrable association between such disparity and postoperative function. Radiological measurements between defined points on the pelvis and femur of the operated hip were compared with the same points on the contralateral joint. A lengthening index was derived and statistical analysis used to compare this with validated functional outcome scores (Harris hip score and the SF36 Health Survey) and patient satisfaction. Our results showed no statistical association between leg-length discrepancy after hip arthroplasty and functional outcome or patient satisfaction.
