Wear Reduction in Total Ankle Arthroplasty Using Highly Crosslinked UHMWPE
نویسنده
چکیده
Introduction: Bearing couples within total ankle arthroplasty (TAA) typically utilize cobalt chromium alloys articulating on ultrahigh molecular weight polyethylene (UHMWPE). Articulation of these surfaces during in vivo loading can generate UHMWPE wear particles, which may then result in osteolysis and component loosening [1]. Osteolysis has been observed following TAA in 15-22% of patient populations [2,3]. Use of highly crosslinked UHMWPE (HXPE) has been shown to reduce wear in other joint systems [4] compared to conventional UHMWPE (CPE); and thus has the potential to improve wear performance of TAA. The goal of this study was to quantify the impact of crosslinking on wear within TAA using loading parameters biomechanically relevant to the ankle joint.

Ultra-high molecular weight polyethylene (UHMWPE) is extensively used in total joint replacements. Wear, fatigue, and fracture have limited the longevity of UHMWPE components. For this reason, significant effort has been directed towards understanding the failure and wear mechanisms of UHMWPE, both at a micro-scale and a macro-scale, within the context of joint replacements. We have previously ...
