title: Isokinetic performance of hip muscles after revision total hip arthroplasty via previous anterolateral approach.
abstract: We investigated the isokinetic performance of hip muscles and clinical outcomes after revision total hip arthroplasty (THA) via same anterolateral approach used in primary surgery. Thirty patients who had undergone previous THA via an anterolateral approach underwent both acetabular and femoral component revision after aseptic loosening. The Harris Hip Score (HHS) was evaluated during a minimum 2-year follow-up. The isokinetic muscle strength of the operated and nonoperated hips was assessed 1 year after surgery. The HHS improved from 49.0 to 77.4. Operated and nonoperated hips exhibited similar isokinetic performance during all measurements (flexion, extension, and abduction) (p>0.05). This prospective study showed that the anterolateral approach preserves abductor strength after revision THA in aseptic cases with acceptable functional and clinical results. The main clinical relevance of this study is that the same anterolateral approach used in previous primary THA is also safe and viable for revision THA.
