Radiographic review of limb-length discrepancy after total hip arthroplasty

Background A clinical and radiographic review was undertaken to evaluate technical causes for limb-length discrepancy (LLD) after total hip arthroplasty and the resultant effect on function. We hypothesized that limb lengthening most commonly occurs as a result of low placement of the acetabular implant. Methods A sample of 116 primary total hip arthroplasties performed between 2005 and 2007 with complete 1-year postoperative clinical outcomes …
