More than 300,000 total hip replacement surgeries are performed in the United States each
year to treat degenerative joint diseases that cause pain and disability. The statistical …

Total hip arthroplasty (THA) surgery has shown dramatic changes in terms of increased
number of procedures and of technical development in recent years. It has been described …

Competition occurs between the osteoblasts in regional microenvironments and pathogens
introduced during surgery, on the surface of bone implants, such as joint prostheses. The …

We report the long-term survival and functional outcome of the Birmingham Hip Resurfacing
(BHR) in patients aged< 50 years at operation, and explore the factors affecting survival …

Metal-on–highly cross-linked polyethylene is considered the preferred bearing surface for
conventional total hip arthroplasty because of its safety profile and excellent results in the …

Background Evidence suggests some metal-on-metal (MOM) THAs have higher rates of
failure and subsequent revision than other bearing surfaces. However, there are few studies …

Background In young patients with osteonecrosis of the femoral head (ONFH), short-stem
total hip arthroplasty (THA) could allow a potential advantage in preserving metaphyseal …

Fretting corrosion in taper joints is of concern since the mid-1970s. Thus, different metallic
and ceramic material combinations have been tested and used clinically. While the stem is …

Objective Revision total hip arthroplasty (THA) is associated with increased cost, morbidity,
and technical challenge compared to primary THA. A better understanding of the risk factors …

A novel polymer-on-metal hip joint prosthesis design that makes use of uni-directional
articulations was developed and tested in this work. The new implant was tested using two …
