Background: A number of surgical approaches are available for total hip arthroplasty (THA), but there limited large-volume, multi-surgeon data comparing the rates early revisions following these approaches. The aim this study was to compare rate revision primary conventional THA related approach. Methods: Data from Australian Orthopaedic Association National Joint Replacement Registry were analyzed all patients who had undergone a osteoarthritis January 2015 December 2018. outcome measure...
The use of computer navigation has been shown to produce more accurate cup positioning when compared with non-navigated total hip arthroplasty (THA), but so far there is only limited evidence show its effect on clinical outcomes. present study analyzed data from the Australian Orthopaedic Association National Joint Replacement Registry assess impact rates all-cause revision and for dislocation following THA.Data all navigated primary THAs performed osteoarthritis in Australia January 1,...
Background and purpose - The Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) was analyzed to determine trends in use of primary total elbow arthroplasty (TEA), the types prostheses used, diagnoses, reasons for revision, whether diagnosis or prosthesis design influenced revision rate.Patients methods During 2008-2018, 1,220 TEA procedures were reported which 140 TEAs revised. Kaplan-Meier estimates survivorship used describe time first hazard ratios (HR) from...
Background and purpose - The increase in shoulder arthroplasty may lead to a burden of revision surgery. This study compared the rate (2nd) following aseptic 1st arthroplasty, considering type primary, class revision.Patients methods All revisions primary total reverse (rTSA group) stemmed stemless (non-rTSA procedures reported our national registry between April 2004 December 2018 were included. 2nd was determined using Kaplan-Meier estimates comparisons made Cox proportional hazards...
Abstract Background There has been decreased use of anatomic total shoulder arthroplasty (aTSA) because reverse TSA (rTSA) is increasingly being used for the same indications. Although short-term studies generally have not found survivorship differences between these implant designs, are often small and their follow-up limited to short term. Likewise, degree which patient characteristics (such as gender, age, American Society Anesthesiologists [ASA] score) may or be associated with calls...
Abstract Background THA is a reasonable surgical option for some patients with fragility fractures of the femoral neck, but it has risk prosthesis dislocation. The combination that reduces dislocation and rate revision surgery not known. Questions/purposes In receiving primary neck fracture, does (1) all-cause or (2) reason differ among standard head size, large dual mobility (DM), constrained liner? (3) Is there difference in when are stratified by age at time surgery? Methods Data were...
Abstract Background The Birmingham Hip Resurfacing (BHR) prosthesis is the most commonly used metal-on-metal hip resurfacing arthroplasty device. current manufacturer-recommended target demographic for BHR male patients, younger than 65 years requiring a femoral head size of ≥ 50 mm. Female older and individuals with smaller femoral-head diameter (≤ mm) are known to have higher revision rates. Prior studies suggest that survivorship when in comparable primary conventional THA, but comparing...
Background: Dislocation remains a leading cause of revision following primary and total hip arthroplasty (THA). The aim the present study was to compare rate second THA major first for treatment dislocation using an implant with standard, large head, dual-mobility, or constrained acetabular liner. Methods: Data were obtained from Australian Orthopaedic Association National Joint Replacement Registry September 1999 through December 2018. All THAs that had been performed osteoarthritis...
Abstract DNA methylation is an ideal trait to study the extent of shared genetic control across ancestries, effectively providing hundreds thousands model molecular traits with large QTL effect sizes. We investigate cis DNAm QTLs in three European (n = 3701) and two East Asian 2099) cohorts quantify similarities differences architecture populations. observe 80,394 associated mQTLs (62.2% probes significant mQTL) be both while 28,925 (22.4%) are identified only a single ancestry. mQTL sizes...
Abstract Background There are increasing reports of corrosion between the femoral head and trunnion in primary conventional THA, resulting metal particulate release often termed trunnionosis. may be heightened awareness this condition because severe soft-tissue reactions initially thought to solely attributable prostheses with a metal-on-metal (MoM) bearing surface. It is unclear what percentage revisions for THA non-MoM surfaces can attributed trunnionosis extent adverse reaction debris...
Abstract Background We aimed to measure the period effect (change over time) in 30‐day mortality after total hip arthroplasty (THA) and knee (TKA) using data from Australian Orthopaedic Association National Joint Replacement Registry. Methods performed an observational study national registry all hospitals performing THA TKA Australia including people undergoing primary elective conventional for osteoarthritis 2003 2017, inclusive. Data Registry, Death Index Bureau of Statistics were used...
Abstract Background TKA generally has excellent long-term survivorship. When a new knee system supersedes previous model, increased survivorship, improved functional performance, or both may be expected, because key areas of design modification are often targeted to address wear, stability, and the patellofemoral articulation. However, not all changes beneficial, our knowledge, arthroplasty been systematically evaluated in context that occur during development systems. Questions/purposes...
The 2021 Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) report indicated that total shoulder replacement using both midhead (TMH) length humeral components and reverse arthroplasty (RTSA) had a lower revision rate than stemmed in anatomic (aTSA)-for all prosthesis types diagnoses. However, there are many factors affect the outcome of replacement, including stem polarity, polyethylene type, glenoid fixation (cemented vs. cementless). aim this study was to...
Abstract Background Mortality after THA and TKA is lower than expected for several years surgery when compared with age- sex-adjusted population data. With long-term followup (beyond approximately 10 years), some evidence has suggested that this trend reverses, such postsurgical mortality higher as more time passes. However, the degree to which may be case not been clearly established. Questions/purposes In large-registry study, we asked: What mortality, adjusted age, sex, calendar year....
Background Total knee replacement (TKR) has been shown to perform differently in patients with rheumatoid arthritis (RA) when compared osteoarthritis (OA). In this study, we compare the survivorship between these two groups and examine patient prosthesis factors that impact revision rate. Methods All RA OA undergoing TKR Australia from 1 September 1999 31 December 2016 were included. Revision rates assessed using Kaplan–Meier estimates of survivorship. The cumulative percent analysed age,...
Periprosthetic joint infection (PJI) is a devastating complication of total knee arthroplasty (TKA). An association between low surgeon volume and higher rates following primary TKA has been suggested. The purpose the present study was to determine if there relationship rate revision for after TKA.We searched Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) identify all procedures that were performed treatment osteoarthritis from September 1, 1999, December...
