PURPOSE: This study hypothesized that the use of bisphosphonates (BPs) after total joint arthroplasty (TJA) is associated with a lower implant revision rate. This study aimed (1) to investigate the association between BP use and the revision rate of TJA and (2) to determine the relationship between the medication period and the revision rate of TJA. METHODS: National Health Insurance Service data on surgeries, medications, diagnoses, and screenings of 50 million Koreans were reviewed...

INTRODUCTION: Dislocation is a serious and common complication and a great concern with the use of total hip arthroplasty (THA) when treating displaced femoral neck fracture (FNF). Dual-mobility (DM) THA might reduce the dislocation risk. We aim to report the dislocation and revision rate of primary DM THA in patients with displaced FNF. MATERIALS AND METHODS: Between 2005 and 2015, 966 consecutive patients (676 women) at mean age 80.5 years (range 42-104) with displaced FNF were operated with DM articulation THA by posterolateral approach (PLA)...

PURPOSE: The hypothesis of the present study was that degenerative fibro-ostosis (FO) of the ischial hamstring tendon insertion is a risk factor for heterotopic ossification (HO) following THA. METHODS: We followed 103 consecutive patients (43 males, 60 females, mean age 61 years) who underwent unilateral cementless THA for primary hip osteoarthritis and investigated the incidence of HO within the first 12 months after surgery. On pre-operative radiographs, a standardized evaluation for FO of the ischial hamstring tendon insertion concerning horizontal, vertical, and square dimensions was performed...

BACKGROUND: Long-term trends in serum metal ion concentration after metal-on-metal (MoM) total hip arthroplasty (THA) are unclear. In most studies, serum metal ion levels increase initially and remain constant during follow-up. However, there are no previous studies that evaluate the metal ion level longitudinally at multiple intervals over the long term. Increasing metal ion levels during the long-term follow-up of patients who underwent cementless MoM THA has been seen, so this study investigated those trends...

BACKGROUND: There is a lack of understanding on relationship between the femoral geometry and outcomes of total hip arthroplasty (THA). We investigated clinical and radiographic outcomes of THA using a cementless tapered wedge stem in patients with Dorr type A proximal femoral morphology and compared with those of type B femurs at a minimum follow-up of 5 years. METHODS: We analyzed 1089 hips (876 patients) that underwent THA using an identical cementless tapered wedge stem...

While femoral intramedullary alignment has been found to be the most accurate and reproducible method for proper femoral component orientation in total knee arthroplasty, certain situations preclude the use of intramedullary alignment, such as ipsilateral long-stem total hip arthroplasty, femoral shaft deformity (congenital or post-traumatic), capacious femoral canal, and retained hardware. These cases require alternative alignment guides, that is, extramedullary alignment. The purpose of this study was to determine the accuracy of intramedullary alignment in reproducing the femoral anatomic axis...

BACKGROUND: Heterotopic ossification (HO) is a well-recognized complication of proximal femoral resection (PFR) surgery in children with cerebral palsy (CP). Although single-dose radiation prophylaxis (SDRP) has been shown to be effective at lowering the rates of HO following adult total hip arthroplasty; there has been limited study examining the efficacy of SDRP for HO prevention in children with CP undergoing PFR. The purpose of this study was to assess the efficacy of SDRP in children with CP undergoing PFR...

No study has compared the prevalence of fretting and corrosion at the trunnion of cobalt-chrome (Co-Cr) and zirconia ceramic heads in the same patients. The authors sought to compare the prevalence of fretting and corrosion at the trunnion after total hip arthroplasty with a 32-mm Co-Cr or a 32-mm zirconia ceramic head-on-polyethylene bearing. Isolated revision of the ace-tabular components was performed in 78 patients (156 hips) for polyethylene wear and osteolysis of the acetabulum. Seventy-eight Co-Cr head-titanium alloy stem pairs were compared with 78 zirconia ceramic head-titanium alloy stem pairs in the same patients...

BACKGROUND: Early postoperative mobilisation is important for enhanced recovery, but can be hindered by orthostatic intolerance, characterised by dizziness, nausea, vomiting, feeling of heat, blurred vision and ultimately syncope. Although the incidence of orthostatic intolerance following total hip arthroplasty has been identified, few studies have yet investigated potential risk factors for developing orthostatic intolerance after hip arthroplasty. OBJECTIVES: The aim of this study was to assess the incidence of orthostatic intolerance on the first postoperative day after total hip arthroplasty, potential predisposing risk factors for developing orthostatic intolerance and its effect on length of stay...

PURPOSE: Acetabular revision of failed total hip arthroplasty (THA) is often associated with severe bone loss. Therefore, a variety of revision implant systems has been developed during recent years, with the augment-and-modular-cage system being one of the newest additions to this portfolio. Together with biologic downsizing by means of impaction bone grafting, this uncemented system promises a high modularity and versatility to treat all acetabular defects up to Paprosky types IIIa and IIIb without pelvic discontinuity...

INTRODUCTION: In the last three decades, total hip replacement in young patient became a habitual procedure. Principles of bone preservation are pushing many surgeons to implant conservative femoral components in patient younger than 65 years. Despite an overall good survivorship and clinical outcomes of conservative implants, failed cases are reported and the need to revise a conservative femoral component became an occasional procedure (with high prevalence of failed resurfacing implants)...

BACKGROUND: Large-diameter head metal-on-metal (MoM) bearings in total hip arthroplasty (THA) are associated with increased whole blood levels of chromium (Cr) and cobalt (Co), adverse reactions to metal debris (ARMD) and poor survival rates. The prevalence of high metals concentrations, ARMD and the risk of revision surgery may vary significantly among different prostheses and long-term studies are few. This single-center study reports the long-term results of the 38-mm MoM bearing system...

BACKGROUND: There has been a shift from cemented to uncemented hip arthroplasty. One popular uncemented combination is the R3 acetabular cup with Polarstem, having the lowest revision rate in the UK National Joint Registry. However, there are no medium-term clinical outcomes on this combination in the literature. The aim of this study is to review our centre's outcomes with this combination using conventional bearings with a minimum of 7-year follow-up. METHODS: Using our centre's arthroplasty database, we identified all patients that underwent a total hip arthroplasty using these implants from August 2009 to December 2010...

Osteonecrosis of the femoral head occurs because of the suppression of blood circulation. At the level of the area affected by the ischemic phenomenon, there are two types of events, in the first stage there is necrosis of the cellular elements, followed by a reparatory phase of the spongy bone tissue. The objective of the study was the histological and immunohistochemical (IHC) analysis of bone metabolism in the repair phase. We observed the action of the main cells involved in the remodeling, the osteoblasts and the osteoclasts, following the reaction of the markers of their activity: osteoprotegerin, osteonectin, osteopontin...

Pseudotumors are not uncommon complications after total hip arthroplasty (THA) and may occur due to differences in bearing surfaces of the head and the liner ranging from soft to hard articulation. The most common causes of pseudotumors are foreign-body reaction, hypersensitivity and wear debris. The spectrum of pseudotumor presentation following THA varies greatly-from completely asymptomatic to clear implant failure. We report a case of pseudo-tumor formation with acetabular cup aseptic loosening after revision ceramic-on-metal hip arthroplasty...

Purpose: Pain caused by osteoarthritis is primarily nociceptive pain; however, it is considered that a component of this pain is due to neuropathic pain (NP). We investigated the effects of total hip arthroplasty (THA) in patients with NP diagnosed by the PainDETECT questionnaire. Materials and Methods: One hundred sixty-three hips (161 patients) were evaluated. All patients were asked to complete the PainDETECT questionnaire based on their experience with NP, and clinical scores were evaluated using the Japanese Orthopaedic Association (JOA) Hip Score before and after THA...

In Western patient populations, the reported incidence of imaging-demonstrated deep vein thrombosis (DVT) after total hip arthroplasty (THA) is as high as 70% without prophylaxis. The reported rates of symptomatic pulmonary embolism (PE) after THA in recent studies range from 0.6% to 1.5%, and the risk of fatal PE ranges from 0.11% to 0.19% in the absence of prophylaxis. Predisposing factors to DVT in western patients include advanced age, previous venous insufficiency, osteoarthritis, obesity, hyperlipidemia, dietary and genetic factors...
