OBJECTIVES Analysis of discrepancies between patient and surgeon expectations before total hip arthroplasty (THA) should enable a better understanding of motives of dissatisfaction about surgery, but this question has been seldom studied. Our objectives were to compare surgeons' and patients' expectations before THA, and to study factors which affected surgeon-patient agreement. METHODS 132 a...

BACKGROUND Patients with hip osteoarthritis (OA) have muscular weakness, impaired balance, and limp. Deficits in the different limb muscles and their recovery courses are largely unknown, however. We hypothesized that there is persisting muscular weakness in lower limb muscles and an impaired balance and gait 2 years after THA. PATIENTS AND METHODS 20 elderly patients with unilateral OA were ...

CONTEXT Although prevalence of obesity and incidence of total joint arthroplasty (TJA) have dramatically increased over the last two decades in the U.S., little is known of the preoperative and postoperative weight patterns of patients undergoing TJA. OBJECTIVE To describe the preoperative and postoperative weight patterns of patients undergoing TJA and evaluate characteristics associated wit...

Leg-length inequality after total hip arthroplasty (THA) is a source of patient morbidity and concern, potentially contributing to nerve palsies, low back pain, and abnormal gait mechanics. The purpose of this study was to compare the degrees of leg-length inequality in patients undergoing primary THA via 3 surgical approaches: anterior, conventional posterior, and posterior-navigated (ie, usin...

The Global Orthopaedic Registry (GLORY) has been designed to monitor a broad range of complications and outcomes that occur following total hip arthroplasty (THA) and total knee arthroplasty (TKA). GLORY provides global 'real-world' data, in contrast to the data generated by the controlled conditions of clinical trials. The results to date show an overall incidence of both in-hospital and post-...

Avascular necrosis (AVN) may confer an increased risk of complications and readmission following total hip arthroplasty (THA). However, current risk-adjustment models do not account for AVN. A total of 1706 patients who underwent THA for AVN from 2011 to 2013 were selected from the American College of Surgeon's National Surgical Quality Improvement Program database and matched 1:1 to controls u...

INTRODUCTION Although total hip arthroplasty (THA) is superior to bipolar hemiarthroplasty (BHA) for displaced femoral neck fracture in terms of hip pain, function and reoperation rate, THA has a higher rate of dislocation. The direct anterior approach (DAA) and a dual mobility cup (DMC) are associated with lower rates of dislocation. The aim of this study was to investigate the outcomes of THA...

The aim of our study was to evaluate the effectiveness of debridement, antibiotics, irrigation and retention (DAIR) in patients who developed a periprosthetic joint infection (PJI) after primary hip or knee arthroplasty in two community hospitals in the Netherlands. We retrospectively collected data in two hospitals in the Netherlands on all episodes of PJI after primary hip (THA) and knee arth...

OBJECTIVE Several studies investigated the association between bisphosphonate use and the risk of implant revision after total hip or knee arthroplasty (THA or TKA); However, the findings were inconsistent. We performed this meta-analysis to evaluate the overall relative risk of such an event. METHODS We searched the PubMed, EMBASE and Cochrane library databases to identify relevant publicati...


 Tha?bit b. Qurra (d. 288/901), a Sabian of H?arra?n, and his descendants remained in their ancestral religion for six generations. Why did they persist despite pressure to convert? This article argues that religious self-identification as could be distinct advantage Baghdad’s elite circles. It focuses on Tha?bit’s great-grandson Abu?
