BACKGROUND: Dislocation is a leading cause of revision after primary total hip arthroplasty (THA). Although more common in the first few years after the procedure, dislocation can occur at any time. This study investigated the difference in late dislocation in ceramic-on-ceramic (CoC) bearings compared with metal-on-polyethylene and ceramic-on-polyethylene bearings in THA. METHODS: Data were used from the Australian Orthopaedic Association National Joint Replacement Registry, and the cumulative percent revision for dislocation was estimated using the Kaplan-Meier method for the different bearing surfaces...

Aseptic loosening of implants remains the most common reason for revision surgery for hip, knee, or ankle prostheses. Although a great scientific effort has been made to explain the underlying mechanisms it remains poorly understood, complex, and multifactorial. Many factors, including age, body weight, activity lesions, implant design, fixation methods, material proprieties, immunologic responses, and biomechanical adaptations to total ankle replacement all contribute to the development of periprosthetic osteolysis...

BACKGROUND: Aseptic loosening due to bone remodelling processes after total hip replacement is one common cause for revision surgery. In human medicine, dual-energy X-ray absorptiometry (DEXA) is the gold standard for quantitative evaluation of bone mineral density, whereas in veterinary medicine conventional radiography is used for follow-up studies. Recently, a method has been described using digital X-ray images for quantitative assessment of grey scale values of bone contrast. Therefore, the aim of the present study was to evaluate the correlation of bone mineral density (BMD) measured by DEXA with grey scale values (GV) measured in digital X-ray images (RX50, RX66) ex vivo...

INTRODUCTION: In younger patients, ceramic-on-ceramic (CoC) bearing surfaces are usually recommended for total hip replacement (THR) because of their low wear rate and longer expected functional life. Although technical advancements have reduced the risk of ceramic bearings fracture, this complication remains a major concern. CASE DESCRIPTION: We present the case of a 56-year-old patient undergoing 3 revision hip arthroplasties of the right hip due to ceramic liner fractures...

We present the case of a 94 years- old patient, which was operated 14 years ago of a right total knee replacement for osteoarthritis, actually she suffers of pain and instability; her X ray shown polyethylene wear without loosening of the metal components. The polyethylene insert is not manufactured anymore so we decided cement a new polyethylene insert on the native tibial baseplate. The two years follow up show us a patient asymptomatic, good function and no radiolucencies on the tibial component. We only found a similar case report in Madrid and we believed that this decision, taken from total hip revisions, will succeed...

OBJECTIVES: For patients with femoral neck fractures, total hip arthroplasty (THA) demonstrates superior outcomes compared with hemiarthroplasty. However, hemiarthroplasty remains a common treatment for femoral neck fractures and the conversion rates are unknown. We compared the results of the 2 procedures using a Medicare database. METHODS: We assembled a cohort of 70,242 patients 65 to 90 years of age with an ICD9 diagnosis and matching Current Procedure Terminology code for femoral neck fracture between 2008 and 2012...

Early detection of adverse local tissue reaction (ALTR) to prosthetic hip wear debris is vital to improve the success of revision surgery. Magnetic resonance imaging with metal artefact reduction sequencing (MARS MRI) is considered the modality of choice to provide cross-sectional imaging of the soft tissues. The areas adjacent to the prosthesis are, however, not readily imaged using these protocols. Ultrasound has also been recommended as an imaging modality in the follow-up of hip replacement surgery. We decided to characterise the typical ultrasound findings in a group of patients undergoing routine biennial review of arthroplastic hips with particular reference to the hip capsule, femoral neck and iliopsoas bursa and tendon adjacent to the implant...

BACKGROUND: Approximately 88,000 primary hip replacements are performed in England and Wales each year. Around 1% go on to develop deep prosthetic joint infection. Between one-stage and two-stage revision arthroplasty best treatment options remain unclear. Our aims were to characterise consultant orthopaedic surgeons' decisions about performing either one-stage or two-stage revision surgery for patients with deep prosthetic infection (PJI) after hip arthroplasty, and to identify whether a randomised trial comparing one-stage with two-stage revision would be feasible...

BACKGROUND: Impaction bone grafting is an established reconstruction technique to address bone loss in revision total hip arthroplasty. Intuitively, it would seem to be a very attractive method as "missing bone is replaced with bone." The potential restoration of bone stock is of particular value in the younger patient who may be facing future revision procedures. METHODS AND RESULTS: Although undoubtedly some units have published good results with this method, more recent long-term data have revealed some of the limitations of this reconstruction technique...

There have been a number of reports on the occurrence of taper corrosion and/or fretting and some have speculated on a link to the occurrence of adverse local tissue reaction specifically in relation to total hip replacement which have a metal-on-metal bearing. As such a study was carried out to compare the magnitude of material loss at the taper in a series of retrieved femoral heads used in metal-on-polyethylene bearings with that in a series of retrieved heads used in metal-on-metal bearings. A total of 36 metal-on-polyethylene and 21 metal-on-metal femoral components were included in the study all of which were received from a customer complaint database...

INTRODUCTION: Impaction Bone grafting (IBG) in Revision THR is challenging and places demands on allograft stores. Identifying a potential synthetic replacement that works in the longer term was the aim of this study. METHODS: We retrospectively reviewed 21 sequential patients who had undergone revision THR using IBG. They were randomised to receive either combined allograft and synthetic graft or Allograft alone. Among the surviving 15 patients, there were total of 25 procedures were carried out...

Hundreds of thousands of revision surgeries for hip, knee, and shoulder joint arthroplasties are now performed worldwide annually. Partial removal of hardware during some types of revision surgeries may create significant amounts of third body metal, polymer, or bone cement debris. Retained debris may lead to a variety of negative health effects including damage to the joint replacement. We describe a novel technique for the better containment and easier removal of third body debris during partial hardware removal...

BACKGROUND: Total hip arthroplasty is the most widely used procedure to treat avascular necrosis (AVN) of the femoral head. Few studies have compared the outcomes of THA in femoral head AVN and primary hip osteoarthritis. Therefore we performed a case-control study to compare THA for femoral head AVN vs. primary hip osteoarthritis in terms of: (1) prosthesis survival, (2) complication rates, (3) functional outcomes and radiographic outcomes, (4) and to determine whether specific risk factors for THA failure exist in femoral head AVN...

BACKGROUND: Deep prosthetic joint infection (PJI) is a devastating complication of joint replacement surgery. It is difficult to treat, and patients often require multiple major revision surgeries to eradicate the infection. Treatment can have negative and long-term impact on patients' quality of life. Understanding current service provision provides valuable information needed to design and evaluate support interventions for patients. AIM: This survey aimed to identify usual care pathways and support in UK National Health Service (NHS) orthopaedic centres for patients receiving revision surgery for PJI after hip or knee replacement...

BACKGROUND: Fixation of the greater trochanter with total hip replacement is challenging and associated with short- and long-term complications. Locking plate technology has been used for fixation of other bones and may be applied successfully in trochanteric fixation. The purpose of this retrospective study was to analyze the utility of the use of trochanteric locking plates in total hip arthroplasty (THA) patients. METHODS: From 2004 to 2014, 32 procedures were performed to fix the greater trochanter in patients with trochanteric fracture, osteotomy, or nonunion in the setting of THA...

BACKGROUND: Hip and knee arthroplasties are common and successful procedures, however, success and durability are not guaranteed. The revision burden, defined as the ratio of implant revisions to the total number of arthroplasties in a specific period, is a measure of the steady state of arthroplasty success in a given registry. This study examines the hypothesis that revision burden would be similar among contemporary joint replacement registries and improving over time compared with historic controls...

BACKGROUND: Demand for revision total hip replacement (RTHR) is increasing. Outcomes after RTHR are varied, with reasonable pain relief but smaller gains in function and mobility. Whether sub-optimal rehabilitation contributes to poorer functional outcomes is unclear. Current rehabilitation is not well defined and there is little research into RTHR rehabilitation. AIMS AND OBJECTIVES: To gather information about the current rehabilitation of patients undergoing planned, single-stage revision or re-revision THR surgery...
