Effect of minimally-invasive implantation of unicompartmental knee arthroplasty on cement penetration and biomechanical stability. An experimental study in human tibiae

摘要

Background: Unicompartmental knee arthoplasty is a well-established treatment modality for anteromedial osteoarthritis and can be implanted minimally-invasive. However, the operation is technically demanding, which might lead to an increased failure rate. This study was conducted to determine the influence of a minimally-invasive approach on biomechanical fixation strength and morphological cement penetration.
