The aim of this study was to systematically review the literature on measurement of muscle strength in patients with femoroacetabular impingement (FAI) and other pathologies and to suggest guidelines to standardise protocols for future research in the field. The Cochrane and PubMed libraries were searched for any publications using the terms ‘hip’, ‘muscle’, ‘strength’, and ‘measurement’ in the ‘Title, Abstract, Keywords’ field. A further search was performed using the terms ‘femoroacetabular’ or ‘impingement’. The search was limited to recent literature only.Objectives
Methods
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
