According to the National Joint Registry, in England and Wales there are approximately 160,000 total hip and knee replacement procedures performed each year. Approximately the same number of hip and knee joints are replaced.
Whilst many people people are completely satisfied with the results, some go on to develop other problems.
Leg length discrepancy (LLD) after total hip arthroplasty (THA) has been associated with back pain and sciatica, gait disorders, general dissatisfaction and dislocation. (Konyvers and Bannister - The importance of leg length discrepancy after total hip arthroplasty, 2004) A study was conducted of 90 people undergoing a primary THA. After operation 56 (62%) limbs were long by a mean of 9 mm and this was perceived by 24 (43%) patients after three months and by 18 (33%) after 12. The mean Oxford Hip Score in patients who perceived true lengthening was 27% worse than the rest of the population after three months and 18% worse after 12. In 55 (98%) patients, lengthening occurred in the femoral component.


If you are about to have a hip replacement or have just a hip replaced, have your consultant check for limb length discrepancy and issue you with orthotics if required.
