BACKGROUND The use of larger femoral heads has been proposed to reduce the risk of dislocation after total hip arthroplasty, but there is a lack of evidence to support this proposal. The aim of this multicenter randomized controlled trial was to determine whether the incidence of dislocation one year after total hip arthroplasty is significantly lower in association with the use of a 36-mm femo...

Options in the management of the deficient femur during revision hip arthroplasty include cemented or cementless fixation. The results with cemented femoral revision have not been historically successful. While the use of extensively coated implants in revision total hip arthroplasty has been more uniformly excellent, issues, such as thigh pain, stress shielding, and lack of bone stock restorat...

BACKGROUND Little is known about the impact of the reason for revision total hip arthroplasty (THA) on the outcomes following revision THA. In this study, our objective was to assess the association of operative diagnosis with patient-reported outcomes (PROs) after revision THA. METHODS We used prospectively collected data from the Mayo Clinic Total Joint Registry that collects pre- and post-...

Background and purpose - In Sweden, less than 5% of patients who undergo total hip arthroplasty (THA) have revision. Younger patients have an increased risk of revision. New prosthetic designs are being introduced in order to improve outcomes further. We investigated whether the introductory phase of new cup designs would increase the revision rate. Patients and methods - All THAs and first-tim...

Background: Cementless total hip replacement is the common THR performed in England, Wales, Northern Irelandand the Isle of Man. The Corail stem is the most popular cementless implant and has a ODEP 10A rating. Review ofits performance in the registry identified an increase rate of revision amongst the smaller stem sizes. However, claritywas not provided on the explanation for this finding. We ...

background: the infection after total hip arthroplasty is one of the major and catastrophic complications and often cause multiple procedures, heavy cost and life threatens and disability for the patient. in this study, we report our experience about infected total hip arthroplasty. methods: in this study, among patients referred to kashani hospital in isfahan, iran from 2001 to 2007, 659 patie...

BACKGROUND Periodic clinical and radiographic evaluation is commonly recommended by orthopaedic surgeons to monitor patients following total joint arthroplasty, yet the compliance with and efficacy of patient follow-up protocols have not been well defined. The purpose of this study was to evaluate patient compliance with early clinical follow-up after total hip arthroplasty or total knee arthro...
