The pattern of pathologies affecting the hips of local Chinese patients is very different from that in western countries. Although there is no data on the actual incidence of hip disease in Hong Kong, one local study involving 647 cases of total hip replacement showed that AVNFH was the commonest cause, contributing to 45.6% of all cases of hip Abstract: Avascular necrosis of femoral head (AVNF...

This review presents current virtual reality based training simulators for hip, knee and other orthopaedic surgery, including elective and trauma surgical procedures. There have not been any reviews focussing on hip and knee orthopaedic simulators. A comparison of existing simulator features is provided to identify what is missing and what is required to improve upon current simulators. In tota...

PURPOSE To assess periods required for resuming car driving in 130 patients who had undergone total hip replacement (THR). METHODS 80 men and 50 women aged 39 to 80 years who had been driving automatic (n=49) or manual (n=81) cars in the previous 3 months and underwent unilateral primary THR of the right (n=85) or left (n=45) hip were recruited. Patients were advised to resume driving after 6...

This article presents a single case study on the feasibility of using a low-cost and portable vision-based system (a Microsoft Kinect sensor) to monitor changes in movement patterns before and after a total hip replacement surgery. The primary subject was a male older adult with total hip replacement who performed two different functional tasks: walking and sit-to-stand. The tasks were recorded...

Background and purpose - Fast-track protocols have been successfully implemented in many hospitals as they have been shown to result in shorter length of stay (LOS) without compromising results. We evaluated the effect of fast-track implementation on the use of institutional care and results after total hip replacement (THR). Patients and methods - 3,193 THRs performed in 4 hospitals between 20...

OBJECTIVE to compare the combined role of genetic variants loci associated with risk of knee or hip osteoarthritis (OA) in post-traumatic (PT) and non-traumatic (NT) cases of clinically severe OA leading to total joint replacement. METHODS A total of 1590 controls, 2168 total knee replacement (TKR) cases (33.2% PT) and 1567 total hip replacement (THR) cases (8.7% PT) from 2 UK cohorts were ge...

BACKGROUND/AIMS To evaluate the clinical course of hip arthritis and the risk factors for hip joint replacement in patients with ankylosing spondylitis (AS). METHODS In this retrospective analysis, we evaluated 488 AS patients at a single tertiary hospital. At baseline and the most recent visit to the outpatient clinic from the patients with hip arthritis in AS, radiographic hip arthritis was...

BACKGROUND Total hip or knee replacement is highly successful when judged by prosthesis-related outcomes. However, some people experience long-term pain. OBJECTIVES To review published studies in representative populations with total hip or knee replacement for the treatment of osteoarthritis reporting proportions of people by pain intensity. DATA SOURCES MEDLINE and EMBASE databases search...

OBJECTIVES To evaluate the performance of a patient assessed outcome measure, the Oxford Hip Score, in a national study of primary hip replacement surgery. DESIGN A survey of patients' health status before undergoing primary hip replacement surgery and three months and one year after surgery. SETTING 143 hospitals in three NHS English regions. PATIENTS 7151 patients admitted for primary t...
