Objective: Osteoarthritis (OA) is a disease impacting the synovial joint complex, yet transcriptional changes specific to shoulder OA remain underexplored. This study aims to profile transcriptomic changes in periarticular tissues from patients undergoing shoulder replacement for OA. By correlating these profiles with QuickDASH scores-a validated measure of worsening shoulder function-this research seeks to understand the gene expression changes associated with clinical decline.

Factors associated with failure of locking plate fixation in proximal humerus fractures.

Injury

November 2024

School of Public Health and Preventive Medicine, Monash University, 553 St Kilda Rd, Melbourne, 3004, Australia; Health Data Research UK, Swansea University Medical School, Swansea University, Singleton Park, Sketty, Swansea SA2 8PP, United Kingdom.

Background: Locking plate fixation remains the mainstay of surgical fixation of unstable proximal humerus fractures, however rates of failure remain high. The aim of this study was to identify risk factors that could be used to predict the likelihood of fixation failure.

Method: Patients with proximal humerus fractures managed with locking plate fixation between 2010 and 2019 at a Level 1 trauma centre were included.

Background: Uncomplicated joint replacement improves pain and other patient-reported outcome measures (PROMs) such as joint function scores and quality-of-life measures. However, the overall impact of periprosthetic joint infection (PJI) and its successful treatment on PROMs is poorly defined. In this study, we describe quality-of-life scores using the 12-item Short Form survey, version 2 (SF-12v2), collected as part of a large, prospective, observational study of PJI.

October 2024

Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR), Adelaide, SA, Australia; Department of Orthopaedics, University Hospital Geelong, Barwon Health, Geelong, VIC, Australia; Barwon Centre for Orthopaedic Research and Education (B-CORE), St John of God Hospital and Deakin University, Geelong, VIC, Australia.

Article Synopsis
  • This study analyzed shoulder arthroplasty procedures from a national registry to evaluate revision rates for osteoarthritis, focusing on the best options for men and women.
  • Three types of shoulder arthroplasties were compared: stemless shoulder arthroplasty (slTSA), stemmed shoulder arthroplasty (stTSA), and cementless reverse shoulder arthroplasty (rTSA), with cumulative percent revision (CPR) calculated over a 7-year period.
  • Results indicated that while all methods had similar revision rates, rTSA showed significantly lower rates than slTSA after 9 months; gender also played a role, with women experiencing lower revision rates than men for stTSA and rT

Background: With advances in health state valuation methods, new value sets may be developed for some countries. Quantifying the impact of moving between existing and new value sets is critical for guiding decisions around utility score interpretation, reporting and comparison with published scores.

Objectives: The aim of this study is to examine, using large-scale national registry data, how the new Australian EQ-5D-5L value set impacts utility scores for patients undergoing joint replacement.

Background: Patient outcomes following low-trauma hip fracture are suboptimal resulting in increased healthcare costs and poor functional outcomes at 1 year. Providing early and intensive in-hospital physiotherapy could help improve patient outcomes and reduce costs following hip fracture surgery. The HIP fracture Supplemental Therapy to Enhance Recovery (HIPSTER) trial will compare usual care physiotherapy to intensive in-hospital physiotherapy for patients following hip fracture surgery.

Article Synopsis
  • * Conducted on a cohort of 741 participants, results showed significant improvements in both OHS and OKS at 12 months post-diagnosis, but no further improvements were noted at 24 months.
  • * Factors that predicted better functional outcomes included clinical cure and early PJI diagnosis, while chronic renal issues and signs of inflammation negatively impacted these outcomes.

Comparable low revision rates of stemmed and stemless total anatomic shoulder arthroplasties after exclusion of metal-backed glenoid components: a collaboration between the Australian and Danish national shoulder arthroplasty registries.

J Shoulder Elbow Surg

December 2024

Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR), Adelaide, SA, Australia; Barwon Centre for Orthopaedic Research and Education (B-CORE), St John of God Hospital and Deakin University, Geelong, VIC, Australia.

Background: The stemmed anatomic total shoulder arthroplasty is the gold standard in the treatment of glenohumeral osteoarthritis. However, the use of stemless total shoulder arthroplasties has increased in recent years. The number of revision procedures are relatively low, and therefore it has been recommended that national joint replacement registries should collaborate when comparing revision rates.

The Latarjet procedure is an established surgical treatment for recurrent glenohumeral joint instability with glenoid bone loss. Intraoperatively, the conjoint tendon and its attachement on the coracoid bone graft is routed through a split in subscapularis where the graft is fixed to and augments the anteroinferior glenoid. The objective of this in vitro study was to quantify the influence of glenohumeral joint position and conjoint tendon force on the lines of action and moment arms of subscapularis muscle sub-regions after Latarjet surgery.

Background: Two classes of primary reverse total shoulder arthroplasty (rTSA), inlay (in-rTSA), and onlay (on-rTSA) were compared to determine differences in rates of revision.

Methods: Between 1 January 2012 and 31 December 2020, all primary in-rTSA or on-rTSA procedures were compared from a large national arthroplasty registry by cumulative percentage revision (CPR). Kaplan-Meier estimates of survivorship and hazard ratios from Cox proportional hazard models adjusted for age, gender, glenosphere size, and humeral fixation determined any associations to the risk of revision.

Background: Increase in supraspinatus tendon thickness (STT) resulting from swimming practice has been observed in those with a history of shoulder pain. The magnitude of change in STT after a swimming session and its rate of recovery may be an indicator of future shoulder pain incidence.

Hypothesis: The supraspinatus tendons that demonstrate a greater increase in thickness as a result of swimming practice will have an increased likelihood of future shoulder pain in a cohort of competitive swimmers over a period of 6 months.

Background: Australian healthcare relies on both private and public sectors to meet the demand for surgical care. Rapid growth of shoulder replacement surgery highlights a disparity in service provision, with two-thirds occurring privately. This study aimed to assess the influence of hospital setting on shoulder replacement revision rate at a national level.

A comparison of revision rates for stemmed and stemless primary anatomic shoulder arthroplasty with all-polyethylene glenoid components: analysis from the Australian Orthopaedic Association National Joint Replacement Registry.

J Shoulder Elbow Surg

February 2024

Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR), Adelaide, SA, Australia; Barwon Centre for Orthopaedic Research and Education (B-CORE), St John of God Hospital and Deakin University, Geelong, VIC, Australia.

Background: We compared the rate of all-cause revision of 2 classes of primary anatomic shoulder arthroplasty, stemmed (stTSA) and stemless (slTSA), undertaken with cemented all-polyethylene glenoid components.

Methods: A large national arthroplasty registry identified 2 cohort groups for comparison, stTSA and l undertaken for all diagnoses between January 1, 2011, and December 31, 2021. A subanalysis from January 1, 2017, allowed capturing of additional patient demographics including American Society of Anesthesiologists score, body mass index, and glenoid morphology.

Development of OA (OA) is multifactorial and is strongly associated with risk factors such as aging, trauma, metabolic disorders, and obesity. Metabolic Syndrome (MetS)-associated OA, collectively coined MetS-OA, is an increasingly recognized entity in which metabolic disorders and low-grade inflammation play a key mechanistic role in the disruption of joint homeostasis and cartilage degradation. Although there have been enormous efforts to discover biomarkers of MetS and OA, studies investigating a pathophysiological link between MetS and OA are relatively limited, and no serum blood marker has proved diagnostic so far.
