Highly cross-linked polyethylene still outperforms conventional polyethylene in THA: 10-year RSA results

Cross-linked compared with historical polyethylene in THA: an 8-year clinical study.

UNLABELLED Wear particle-induced osteolysis is a major cause of aseptic loosening in THA. Increasing wear resistance of polyethylene (PE) occurs by increasing the cross-link density and early reports document low wear rates with such implants. To confirm longer-term reductions in wear we compared cross-linked polyethylene (irradiation in nitrogen, annealing) with historical polyethylene (irradi...

[Polyethylene particles in synovial fluid after knee arthroplasty with a conventional or highly cross-linked polyethylene. Preliminary study].

AIM OF THE STUDY In recent years cross-linked polyethylenes have been developed in an attempt to reduce the wear, as has been demonstrated in knee simulators. The aim is to assess, by counting particles of polyethylene in synovial fluid, whether the reduction in wear is confirmed in patients with a highly crosslinked polyethylene prosthesis. MATERIAL AND METHODS A prospective randomised study...

Hip Resurfacing Using Highly Cross-linked Polyethylene: Prospective Study Results at 8.5 Years.

BACKGROUND Hip resurfacing is an option to consider when treating younger, more active patients. Advantages over total hip arthroplasty include a more normal gait and a lower incidence of thigh pain. METHODS In this prospective study, 190 hip resurfacing procedures (164 participants) were performed using a cobalt-chromium femoral component and a cementless acetabular cup with a 3.8-mm highly ...

Cross-linked Polyethylene Engineered for TKA

Introduction It is well known that the wear resistance of ultra-high molecular weight polyethylene (UHMWPE) improves in proportion to the crosslinking irradiation dose. It is also well known that the mechanical properties and oxidative stability of UHMWPE are affected by the irradiation dose, resin type, and post-irradiation heat treatment, among others factors. Therefore, careful consideration...
