    Summary
    Purpose: The aim of this study was to determine outcomes of total hip replacement (THR) with the Lemania cemented femoral stem. Methods: A total of 78 THR patients were followed and compared to 17 "fit”, healthy, elderly and 72 "frail” elderly subjects without THR, using clinical outcome measures and a portable, in-field gait analysis device at five and tenyears follow-up. Results: Forty-one patients (53%), mean age 83.4years, available at tenyears follow-up, reported very good to excellent satisfaction. Mean Harris Hip and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores were 81.2 and 10.5 points, respectively, with excellent radiological preservation of proximal femur bone stock. Spatial and temporal gait parameters were close to the fit group and better than the frail group. Conclusions: Lemania THR demonstrated very good, stable clinical and radiological results at tenyears in an older patient group, comparable to other cemented systems for primary THR. Gait analysis confirmed good walking performance in a real-life environment.
