BACKGROUND The prevalence of asymptomatic deep vein thrombosis diagnosed by venography after hip or knee replacement remains high despite 7 to 10 days of anticoagulant prophylaxis. However, the risk of symptomatic events in such patients is unclear. We performed a meta-analysis to provide reliable estimates of the risk of symptomatic venous thromboembolism occurring within 3 months of hip or kn...

The function of a total hip replacement is dependent upon the implant design and materials, wear and performance characteristics, short and long-term stability, surgical technique and component placement and alignment. Although the surgeon only directly controls the surgical technique, component placement and alignment, an understanding of the biomechanical performance of total hip replacement ...

OBJECTIVE To test the hypothesis that farmers are at high risk of hip osteoarthritis and to investigate possible causes for such a hazard. DESIGN Cross sectional survey. SETTING Five rural general practices. SUBJECTS 167 male farmers aged 60-76 and 83 controls from mainly sedentary jobs. All those without previous hip replacement underwent radiography of the hip. MAIN OUTCOME MEASURES H...

BACKGROUND Hip and knee arthroplasty aims to restore the joint function and to improve health-related quality of life (HRQoL) in patients with articular damage. It is important to quantify the HRQoL improvement and when this is achieved. The Oxford knee score and the Oxford hip score were developed to evaluate patients after knee and hip arthroplasty. We sought to evaluate HRQoL changes in the ...

Our aim was to determine the success rate of repeated debridement and two-stage cementless revision arthroplasty according to the type of infected total hip replacement (THR). We enrolled 294 patients (294 hips) with an infected THR in the study. There were 222 men and 72 women with a mean age of 55.1 years (24.0 to 78.0). The rate of control of infection after the initial treatment and after r...

Total Hip Replacement (THR) is the most successful operation in medical history, and this editorial would like to take a look at the history of its development and how the contributions of great British orthopaedic surgeons made it possible. Britain continues to produce notable orthopaedic surgeons and special mention will go to the founding father of modern THR, Sir John Charnley. Further, the...

Using a regional arthroplasty register, we assessed the outcome, at five years, of 1198 primary Charnley total hip replacements (THRs) undertaken across a single health region in England in 1990. An independent clinical and radiological assessment was completed for 497 operations, carried out in 18 different hospitals, under the care of 56 consultants and by differing grades of surgeon. The ove...

OBJECTIVES To introduce the practice of a nurse-led orthopaedic clinic for managing stable patients after total hip or knee replacement and to evaluate its efficacy. DESIGN Case series. SETTING A public hospital in Hong Kong. PATIENTS Patients who had stable primary total knee replacement or total hip replacement done for longer than 2 years were managed in a nurse-led total joint replace...

INTRODUCTION Dislocation of a prosthetic hip is the second most common complication after thromboembolic disease in patients undergoing total hip arthroplasty, with an incidence reported as 0.5 to 20%. Although the period of greatest risk for dislocation has been reported to be within the first few months after surgery, late dislocation occurs more commonly then previously thought. CASE PRESE...

This study compared component wear rates and pre-revision blood metal ions levels in two groups of failed metal-on-metal hip arthroplasties: hip resurfacing and modular total hip replacement (THR). There was no significant difference in the median rate of linear wear between the groups for both acetabular (p = 0.4633) and femoral (p = 0.0872) components. There was also no significant difference...
