Restoration of anatomy is essential in total hip arthroplasty (THA) to optimize function and stability. Leg-length discrepancy of ≥10mm is poorly tolerated and can be the subject of litigation. We use a multimodal protocol to optimize soft tissue balancing which involves pre- operative templating, leg-length measurement supine and after positioning, use of an intra-operative leg-length and offset measurement device and implants with standard and high-offset options. Radiological leg-length and femoral offset were measured in a consecutive series of 100 patients who had THA for unilateral arthritis by an independent observer pre- and post-operatively using validated methods and the contra lateral hip as a control.Introduction
