Introduction: Osteolysis around orthopaedic implants, a consequence of the wear process, is a major problem for the long-term survival of the implants. We and others previously reported quantitative versions of the murine calvarial model of titanium particle induced osteolysis [1,2]. However, the most common particle type that is generated from orthopaedic implants is ultrahigh molecular weight...

The crossing internal suture augmentation technique is an all-inside technique of anterior cruciate ligament reconstruction with augmentation of the hamstring tendon autograft with a braided ultrahigh-molecular-weight polyester-polyethylene suture tape resting on the adjustable cortical buttons on both the femoral and tibial sides. The internal suture augmentation acts as a backbone supporting ...

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 pop...

Novel structures with functional gradation in composition and structure were successfully made in Ti-TiO(2) combination using laser engineered net shaping. The addition of fully dense, compositionally graded TiO(2) ceramic on porous Ti significantly increased the surface wettability and hardness. The graded structures with varying concentrations of TiO(2) on the top surface were found to be non...
